          ANALYZE YOURSELF
  The computer can analyze your body and mind.

                Death
  Terrence Lukas wrote a program that predicts when you'll die. 
The program makes the computer ask for your age and sex; then it 
asks about the life and health of your parents and grandparents, 
your weight, your personal habits (smoking, drinking, exercise, 
and sleep), your history of medical check-ups, your social class 
(your education, occupation, and income), and your lifestyle: 
urban or rural, single or married, aggressive or passive, and 
whether you use seat belts. The computer combines all that 
information, to tell you when you'll probably die.
  The program uses the latest statistics from life-insurance 
companies and from medical research. Lukas wrote the program at 
the University of Illinois Medical Center.
  Running the program is fun. Each time you answer a question, 
the computer tells you how your answer affects its prediction. 
You see its prediction bob up and down, until the questions 
finally end, and the computer gives you its final prediction of 
when you'll die. It's like watching the early returns of a 
Presidential election, except the topic is you!
  The computer pops out with surprising comments, based on the 
latest medical research. Here are some comments the computer 
prints:
Professionals usually live longer, except musicians, architects, 
and pharmacists. Why this is true is unknown.

Cooks, chefs, bakers, and other people who work at jobs 
associated with overeating have a lower life expectancy.

Adults that sleep too much use too many hours in nonphysical 
activity. They may be unhappy and sleep as an escape, or may be 
ill. Depressed people have shorter life expectancies.

Moderate drinking (up to two drinks per day) reduces stress and 
aids digestion. Heavy drinking, however, produces physiological 
damage. As for teetotalers, they may have rather rigid value 
systems and may undergo stress in maintaining them.
  The program is on pages 34-36 of the November 1977 issue of 
Kilobaud Microcomputing Magazine.
                                                    Brainwaves
                                         A computer has been 
programmed to read your mind, by analyzing your brainwaves. A 
newspaper article described the program dramatically: you're an 
airplane pilot . . . your plane is going to crash . . . but you 
think ``Up!'', and the plane automatically goes back up! . . . 
because the plane is run by a computer that's reading your 
brainwaves!
                                         But what if the pilot is 
sadistic, and thinks ``Down''?
                                         Anyway, the program 
isn't perfected yet. When the computer tries to distinguish 
brainwaves that mean up from brainwaves that mean down, it gets 
the right answer 75% of the time. In other words, 25% of the time 
it goofs. I'd hate to be in a plane controlled by a computer that 
was having a bad day!
                                         Recently, the U.S. 
Government has shifted the emphasis of this research. The new 
emphasis is more practical: to make the computer ring a buzzer, 
when the pilot's brainwaves indicate the pilot is daydreaming.

                                                    Horoscopes
                                         If you hate horoscopes 
as much as I do, you'll love Adrian Thornton's program. It makes 
the computer print fake horoscopes. The computer asks when you 
were born, computes your sign, and then prints an enchanting 
remark.
                                         For example, if your 
sign turns out to be Capricorn, the computer will print:
You are conservative and afraid of taking risks. You don't do 
much of anything and are lazy. There has never been a Capricorn 
of any importance. Capricorns should avoid standing still too 
long, as they tend to take root and become trees.
                                         If you're a Virgo, the 
computer will print:
You are the logical type and hate disorder. This nitpicking is 
sickening to your friends. You are cold and unemotional and 
sometimes fall asleep while making love. Virgos make good bus 
drivers.
                                         You'll enjoy seeing your 
own ``horror''scope. The complete program is on pages 48-49 of 
the February 1979 issue of Kilobaud Microcomputing Magazine.
            Psychotherapy
  In 1966, Joseph Weizenbaum programmed the computer to act as a 
psychotherapist. On the keyboard, you type whatever thoughts come 
to your mind, and the computer will give you therapy. When typing 
on the terminal, feel free to use whatever words you wish ___ you 
don't have to use a ``computer language''.
  The most amazing thing about the program is that it does a 
decent job of therapy, even though the computer doesn't know what 
you're talking about! Weizenbaum's program contains the 
definitions of only a handful of words; but if you use words the 
computer doesn't know, the computer does an amazingly good job of 
``faking''. For example, if you say, ``My junkapoo is like my 
iliabop'', the computer will continue the conversation by asking 
you, ``In what way?'' even though the computer doesn't know what 
a junkapoo or an iliabop is.
  Here's a conversation between his computer and a patient.
Patient:Men are all alike
Computer:In what way?

Patient:They're always bugging us about something or other.
Computer:Can you think of a specific example?

Patient:Well, my boyfriend made me come here.
Computer:Your boyfriend made you come here.

Patient:He says I'm depressed much of the time.
Computer:I am sorry to hear you are depressed.

Patient:It's true. I am unhappy.
Computer:Do you think coming here will help you not to be 
unhappy?

Patient:I need some help, that much seems certain.
Computer:What would it mean to you if you got some help?

Patient:Perhaps I could learn to get along with my mother.
Computer:Tell me more about your family.

Patient:My mother takes care of me.
Computer:Who else in your family takes care of you?

Patient:My father.
Computer:Your father.

Patient:You are like my father in some ways.
Computer:What resemblance do you see?

Patient:You are not very aggressive, but I think you don't want 
      me to notice that.
Computer:What makes you think I am not very aggressive?

Patient:You don't argue with me.
Computer:Why do you think I don't argue with you?

Patient:You are afraid of me.
Computer:Does it please you to believe I am afraid of you?

Patient:My father is afraid of everybody.
Computer:What else comes to mind when you think of your father?

Patient:Bullies.
Computer:Does that have anything to do with the fact that your 
      boyfriend made you come here?
  Like the famous psychotherapist Carl Rogers, the computer asks 
probing questions that make the patient open up, but it never 
gives advice: the patient must discover the truth for herself.
  I'll explain exactly how the program works, so you can become a 
psychotherapist yourself, and get hundreds of thousands of 
dollars by bilking your patients.
                                         The computer begins by 
replacing some of the patient's words:
Typed by patient                                   Replacement
                                           mom     mother

                                           were    was
For example, the sentence Well, my boyfriend made me come here 
becomes Well, your boyfriend made you come here.
                                         The computer hunts 
through the revised sentence or paragraph for one of these 
keywords. . . . 
Category 8:                                  computer, computers, 
machine, machines

                                             italiano, maybe, my, 
                                             no, perhaps, sorry, 
                                             what, when, why, 
                                             yes, you@, you're
If the computer finds several of those keywords, it chooses the 
one in the highest category; if they lie in the same category, it 
chooses the one the patient typed first.
  Then it looks up the keyword in this phrasebook:

  your . . .                Your . . . 
you're                      (treat as ``you@ are'')
  For example, if the keyword is sorry, the computer looks up 
sorry in the phrasebook, which says to print ``Please don't 
apologize.''
                                                     Suppose the 
patient types, ``If the job is lousy, he'll die.'' The keyword is 
if. In the phrasebook, if is followed by three dots, which stand 
for the part of the clause that comes after if, which is ``the 
job is lousy''. (The computer figures out where the clause ends 
by looking at the punctuation.) The phrasebook says to print ``Do 
you think it's likely that the job is lousy?''
                                                     The symbol @ 
serves just to locate the correct keyword in the phrasebook. 
Thereafter, it's ignored.
                                                     Here's what 
happens if the keyword is you@. After locating you@ in the 
phrasebook, the computer ignores the @. If the patient's revised 
sentence contains you want . . . or you need . . . , the computer 
prints ``What would it mean to you if you got . . . ?'' If the 
patient's sentence contains you are . . . sad, the computer 
prints ``I am sorry to hear you are sad.''
                                                     For each 
reply in the phrasebook, Weizenbaum stored a list of 
alternatives. For example, here are the alternatives to ``Please 
don't apologize'':
Apologies are not necessary.
What feelings do you have when you apologize?
I've told you that apologies are not required.
While chatting with the patient, the computer keeps track of 
which replies it has printed already, and uses the alternatives 
to avoid repetition.
                                                     If the 
patient's statement doesn't contain a keyword, the computer may 
give one of these replies:
I am not sure I understand you fully.
Please go on.
What does that suggest to you?
Do you feel strongly about discussing such things?
Or it may take a second look at earlier parts of the 
conversation, retrieve a clause that contained your . . . , and 
print one of these replies:
Let's discuss further why your . . . .

Earlier you said your . . . .

Does that have anything to do with the fact that your . . . ?
For example, it may retrieve the clause Your boyfriend made you 
come here and print:
Does that have anything to do with the fact that your boyfriend 
made you come here?
                                                     The program 
was written at the Massachusetts Institute of Technology (MIT). 
The programmer, Joseph Weizenbaum, named the program ``Eliza'', 
to honor Eliza Doolittle ___ the woman in My Fair Lady and 
Pygmalion, who learned to speak English and have a good 
conversation.
  Some people think Weizenbaum's program shows that computers can 
communicate as well as psychotherapists. But Weizenbaum himself 
holds the opposite view; he believes the program shows that 
psychotherapists communicate as poorly as computers.
  You can buy a disk called Golden Oldies, which contains 
imitations of four classic programs: Adventure, Pong, Life, and 
Weizenbaum's Eliza. The disk is published by Software Country, 
distributed by Electronic Arts, costs about $35, and comes in 
versions for the Apple 2e & 2c, Macintosh, Commodore 64, Amiga, 
Atari 800 XL, and IBM PC.
  Improved versions After Weizenbaum invented Eliza, other 
programmers invented improvements. For example, in one of the 
improved versions, whenever the computer doesn't understand you, 
it reacts like the typical rich psychotherapist ___ it bluffs and 
says:
I understand fully. Please go on.
  The computer never really understands what you say. For 
example, in one version, if you say ``My, my, my!'', the computer 
will reply:
Tell me more about your your your.
  Radio Shack's headquarters phoned me, and asked for permission 
to use my explanation of Weizenbaum's program. I agreed, 
whereupon Radio Shack invented and sold a version that makes the 
computer talk ___ by using a voice synthesizer. You'll freak out 
when you hear the computer's voice giving you therapy. Radio 
Shack's program costs $15, comes on tape, and requires a model 1 
or model 3 TRS-80. To hear the voice, you must buy the voice 
synthesizer. (But even if you don't buy the voice synthesizer, 
the program will impress you.)
                             The cheapest way to get a version of 
Eliza is to buy a book called BASIC Computer Games Volume 2 
(TRS-80 edition). Get it at your local Radio Shack store. It 
costs just $7 and includes 84 programs ___ one of which is a 
version of Eliza written in BASIC. That version of Eliza isn't as 
good as the original; but since it's cheap and written in BASIC, 
you'll enjoy buying it for self-study. Here's part of a 
conversation between that version and a patient:
Patient:                         I am not the greatest 
conversationalist.
Computer:                        Do you believe it is normal to 
                                 be not the greatest 
                                 conversationalist?

Patient:                         Yes.
Computer:                        I see.

Patient:                         How can you see without any 
eyes?
Computer:                        Don't you believe that I can see 
without any eyes?

Patient:                         No. So prove it.
Computer:                        Are you saying ``no'' just to be 
negative?

Patient:                         Absolutely not.
Computer:                        You are being a bit negative.

Patient:                         So you want to fight, do you?
Computer:                        We were discussing you ___ not 
me.

Patient:                         Don't back down, friend.
Computer:                        Why do you bring up the topic of 
friends?

Patient:                         I don't have any friends.
Computer:                        Don't you really have any 
friends?

Patient:                         No, not really.
Computer:                        Why not?
                             Unfortunately, most versions of 
Eliza are passive. The typical Eliza program works well only if 
the patient's talkative. If the patient doesn't say much, the 
program can't react too much and is useless.
                             Recently, John Holland invented a 
better version of Eliza. His version's more aggressive. He calls 
it ``Analiza 2'' (because it ``analizas'' the patient). If the 
patient's too quiet or too boring or too uninformative, Analiza 2 
makes the computer give the patient a ``jolt'', by asking an 
electrifying question or making a ridiculous Zen-like statement. 
For example, the computer might ask, ``Did you ever try to commit 
suicide with a hammer?'' Here's a list of the computer's favorite 
``jolts'':
Nasty questions the computer asks
Did you ever try to commit suicide with a hammer?
Is your interest in sex still not very strong?
Do you want to know what I suspect?

Prying questions the computer asks
Tell me, what is your worst fear?
Why don't you tell me about your first romance?
I want to know about your lifestyle.
Tell me what is troubling you.
Honestly now, what is your biggest concern?

Ridiculous statements the computer makes
With strong drugs you can learn to control your concern!
You certainly are curious!
And you are obstinate!

Complaints the computer makes
You seem inhibited.
This isn't really very exciting.
Getting started is often difficult.

Comments the computer makes about timing and complexity
Well, time is almost up. Is there anything else you want to 
discuss?
I hate to bring this up, but you still owe me $53.00 from your 
last visit!
Last time you were extremely inquisitive. Have you abandoned 
seeking simple solutions?
Last time you were difficult to understand. Were you trying to 
confuse me?
Let's keep it simple this time.
Say, I am having trouble with your long sentences. Keep it 
simple. I am only human.
                             Yes, your patient will love to hear 
the computer say it's ``only human''. You can get Analiza 2 for 
$50 from Supersoft (Box 1628, Champaign, IL 61820, 217-359-2112). 
It runs on most computers that have the CP/M operating system.
  Paranoid What if the world becomes full of computerized 
psychoanalysts, and there aren't enough patients to keep them 
busy? Kenneth Colby solved that problem: in 1971 at Stanford 
University, he programmed a computer to be a crazy patient. 
Specifically, he programmed his computer to be a paranoid 
schizophrenic. In the following conversations, psychiatrists 
interrogate his computer.
Conversation 1
Psychiatrist:How long have you been in the hospital?
Computer:About a week.

Psychiatrist:Are you depressed?
Computer:No.

Psychiatrist:Were you taking drugs?
Computer:No.

Psychiatrist:What is your problem?
Computer:People make me nervous.

Psychiatrist:How do they do that?
Computer:They stare at me.

Psychiatrist:Why?
Computer:Maybe they don't like the way I look or something.

Psychiatrist:Do you look unusual in some way?
Computer:Why are you interested in my looks?

Psychiatrist:Because you said people stare at you.
Computer:Well, sometimes.

Psychiatrist:How do you get along with people?
Computer:I don't communicate very much with the others.

Psychiatrist:Why not?
Computer:They don't realize what's going on most of the time.

Psychiatrist:What is going on?
Computer:Do you know how the underworld operates?

Conversation 2
Psychiatrist:How are you today?
Computer:OK.

Psychiatrist:What is your name?
Computer:My name is Frank Smith.

Psychiatrist:How old are you?
Computer:Twenty-eight.

Psychiatrist:Are you married?
Computer:No.

Psychiatrist:What sort of work do you do?
Computer:I work in the post office.

Psychiatrist:Why are you in the hospital?
Computer:I shouldn't be here.

Psychiatrist:Who brought you here?
Computer:The police.

Psychiatrist:What trouble did you have with the police?
Computer:Cops don't do their job.

Psychiatrist:What do they do instead?
Computer:Cops arrest the wrong people.

Psychiatrist:They arrest the right ones sometimes.
Computer:The law should get those Italian crooks.

Psychiatrist:Are you Italian?
Computer:My background is British but I was born in this country.

Psychiatrist:Do you know any Italian crooks?
Computer:I try to avoid the underworld.

Psychiatrist:Are you afraid of the underworld?
Computer:The Mafia are the worst gangsters.

Psychiatrist:Are you connected with the Mafia?
Computer:You know, they know me.

Psychiatrist:How do they know you?
Computer:They spy on me.

Psychiatrist:Why do they?
Computer:They want to get false evidence to frame me.
Psychiatrist:                                  What do they have 
against you?
Computer:                                      They are out to 
get me.

Psychiatrist:                                  What for?
Computer:                                      I have 
incriminating evidence against the Mafia.

Psychiatrist:                                  Are you sure of 
all this?
Computer:                                      You don't believe 
me?

Conversation 3
Psychiatrist:                                  Tell me something 
about yourself.
Computer:                                      I went to the 
track at Bay Meadows a while back.

Psychiatrist:                                  What happened 
there?
Computer:                                      There's a lot of 
crooked gambling there.

Psychiatrist:                                  Why do you think 
the gambling is crooked?
Computer:                                      I have worried 
                                               that gangsters 
                                               have too much 
                                               power in this 
                                               country.

Conversation 4
Psychiatrist:                                  How do you like 
the hospital?
Computer:                                      I don't 
communicate very much with others.

Psychiatrist:                                  Do other people at 
the hospital get on your nerves?
Computer:                                      I shouldn't have 
come here.

Psychiatrist:                                  Why do you say you 
shouldn't have come here?
Computer:                                      They made me come 
here.
                                         The computer's response 
depends on how much FEAR, ANGER, and MISTRUST it has at the 
moment. Those three variables are affected by what the 
psychiatrist says. For example, if the psychiatrist gives the 
computer a compliment, the FEAR, ANGER, and MISTRUST usually 
decrease. But if MISTRUST is already high, the computer 
interprets the compliment as a sly attempt at pacification, and 
its ANGER increases instead of decreases. ANGER can also be 
increased by questions that humiliate (Tell me about your sex 
life) or imply subjugation (Perhaps you should stay in the 
hospital longer).
                                         To prove his computer is 
paranoid, Colby had 8 psychiatrists interview it and also 
interview paranoid humans via teletypewriters. Transcripts of all 
the interviews were sent to psychiatrists around the country, who 
were asked to judge whether each interview was with a human or 
with the computer. The psychiatrists were unable to tell the 
difference: only 51% of their guesses were correct.
                                         Some computerists got 
the ``brainstorm'' of hooking Weizenbaum's computer to Colby's, 
to see whether the computerized psychotherapist could cure the 
computerized schizophrenic. The experiment was a disaster: both 
computers were so passive that the discussion rapidly degenerated 
into trivia.
                                         But so do conversations 
between humans!

            FALL IN LOVE
  Can the computer help you fall in love? Here are some famous 
attempts, in chronological order. (I've rounded all dates to the 
nearest 5 years.)

           TV love (1960)
  A computer appeared on national TV, to make people fall in 
love.
  Guys and gals in the audience answered questionnaires about 
their personality and fed them into the computer. The computer 
chose the guy and gal that were most compatible. That guy and gal 
had their first blind date on national television.
  Each week, that scenario was repeated: the computer chose 
another couple from the audience.
  Each lucky couple appeared on the show again several weeks 
later so the audience could find out whether the couple was in 
love.
  One of the couples was unhappy: the gal didn't like the guy, 
even though she wanted to like him. She volunteered to be 
hypnotized. So, on national TV, a hypnotist made her fall in love 
with her partner.
  The computer was a huge Univac. Today, the same kind of 
matching could be done with a microcomputer. Any volunteers?

   Computer-dating services (1965)
  College students began relying on computers, to find dates. 
Here's how the typical computer-dating service worked. . . .
  You answered a long questionnaire ___ about 8 pages. The 
questionnaire asked about your sex, age, height, weight, hair 
color, race, religion, how often you drank and smoked, how 
``handsome'' or ``attractive'' you were (on a scale of 1 to 10), 
how far you wanted to go on your first date, whether you wanted 
to get married soon, and how many children you'd like. It also 
asked many questions about your personality.
  One of the questions was:
Suppose you receive in the mail some spoons you didn't order. The 
accompanying note says the spoons were sent by a charitable 
organization, and begs you to either send a contribution or 
return the spoons. You don't like the spoons. What will you do?
1. Keep the spoons without paying.
2. Return the spoons.
3. Pay for the spoons.
  Another question was:
A girl returned from her date after curfew. Her excuse was that 
her boyfriend's car broke down. What's your reaction?
Again, you had a multiple-choice answer. One of the choices was, 
``Ha!''
  For each question, you had to say how you would answer it, and 
how you'd want your date to answer it. That was tough. What if 
you wanted your date to be stunningly beautiful but also humble? 
What if you wanted to meet somebody who's ugly and insecure 
enough to be desperate to have sex? Such issues were debated in 
college dorms throughout the nation.
                                         After completing the 
questionnaire, you mailed it with about $10 to the 
computer-dating service. Within two months, the service would 
send you the names, addresses, and phone numbers of at least 5 
people you could date. If your personality was very easy to 
match, the service might send you more than 5 names; but even if 
your personality was lousy, you'd get at least 5. Periodically 
throughout the year, you'd also get updates that matched you with 
people who enrolled after you.
                                         The most popular 
computer-dating service was Operation Match, started by students 
at Harvard. Its main competitor was Contact, started by students 
at M.I.T. Both services quickly became profitable and had 
subscribers from all across the country.
                                         One gal's personality 
was so wonderful that the computer matched her with 110 guys! She 
had to explain to her mom why 110 guys were always on the phone 
___ and she had to figure out how to say ``no'' to 109 of them.
                                         One gal got matched to 
her roommate's boyfriend. They didn't stay roommates long.
                                         When I was a freshman, I 
applied to both services, to make sure I'd meet ``the gal of my 
dreams''. Contact sent me names of gals at prestigious schools 
(such as Wellesley and Bennington), while Operation Match sent me 
names of gals at schools such as the State University of New York 
at Albany.
                                         I thought I was the only 
nut desperate enough to apply to both services, but I got a 
surprise! When I saw the list of names from Contact and the list 
from Operation Match, I noticed a gal who appeared on both lists! 
Like me, she'd been desperate enough to apply to both services, 
and both computers agreed she'd be a perfect match for me!
                                         I had a date with her 
but couldn't stand her.
                                         When I'd answered the 
questionnaire, I was a very bashful boy, so the computer matched 
me to bashful girls. But by the time I received the computer 
printout, I'd become wilder, and the girls the computer 
recommended were no longer ``my type''.
                                         Contact raised its price 
to $15, then $20. But $20 was still cheap for what you were 
getting.
                                         Contact ran a newspaper 
ad that seemed to be selling groceries. It said, ``Dates ___ 2 
per pound''. The ad then explained that one gal got enough dates 
so that, when she totaled the weight of their bodies, she figured 
they cost her 2 per pound.

                                            The Dartmouth dater (1965)
                                         When Dartmouth College 
was still all-male, a student there wrote a cruel program that 
evaluated dates by asking lots of ``practical'' questions such 
as:
Is she pretty?
How far away does she live?
Does she have a car?
                                         I put down that I was 
dating a 14-year-old girl who was 7 feet tall and weighed 300 
pounds but had a perfect personality. I gave her personality a 
10, and even said that she lived nearby and had a car.
                                         In spite of her 
excellent personality, the computer didn't like her. The computer 
said:
She must be pregnant. Where did you get that pig?
Worst score yet produced by this computer!

         Video dating (1975)
  During the 1970's, people wanted everything to be natural. They 
wanted ``natural food'' and ``natural love''.
  Since computerized love seemed unnatural, its popularity 
declined. Operation Match and Contact went out of business.
  They were replaced by video dating, in which a video-dating 
service shows you videotapes of members of the opposite sex and 
lets you contact the person whose videotape you like best. That 
way, you never have a ``blind'' date: you see the person on 
videotape before you make the date. The service also makes a 
videotape of you!
  The video-dating service tapes thousands of people. Since you 
don't have enough time to look at thousands of tapes, the service 
tells you to answer a questionnaire, which is fed into a 
computer. The computer tells you which people you're most 
compatible with; then you look at those people's tapes.

       Computer dancing (1975)
  At a Connecticut prep school (Hotchkiss), the head of the 
computer center arranged a ``computer dance''.
  All the students answered questionnaires, which were fed into a 
computer. The computer matched the boys with the girls, so each 
boy got one girl. The boy had to take the girl to the dance.
  The computer center's staff announced the dancing partners in a 
strange way: one morning, the students found all the halls 
decorated with strips of punched paper tape, saying (in 
billboard-style letters) messages such as ``George Smith & Mary 
Jones''. If you were a student, you looked up and down the halls 
(your heart beating quickly), to find the tape displaying your 
name alongside the name of your mysterious computer lover.
  Shrieks and groans. ``Aarrgghh! You wouldn't believe who the 
computer stuck me with!''

      Computer weddings (1980)
  Here's how the first true ``computer marriage'' occurred. . . . 
  One company's terminal was attached to another company's 
computer. A programmer at the first company often asked a 
programmer at the second company for help. They contacted each 
other by typing messages on their terminals, and let the computer 
relay the messages back and forth. One of the programmers was a 
guy, the other was a gal, and they fell in love, even though they 
had never met. Finally, the guy typed on his terminal, ``Let's 
get married''. The gal typed back, ``Yes''. And so they got 
engaged ___ even though they had never met.
  Their marriage ceremony used three terminals: one for the guy, 
one for the gal, and one for the minister. The minister typed the 
questions at his own terminal; then the guy and gal typed back, 
``I do''.
  Reverend Apple Reverend Apple is an Apple computer programmed 
to perform marriage ceremonies.
  It performed its first marriage on Valentine's Day, 1981. The 
groom was a guy named Richard; the bride was a gal named Debbie. 
The computer printed the standard wedding-ritual text on the 
screen, and then asked the usual questions. Instead of answering 
``I do'', the bride and groom just had to type ``Y''.
  Reverend Apple is smart. For example, if the bride or groom 
types ``N'' instead of ``Y'', the computer beeps, tells the 
couple to try again, and repeats the question.
                                         The program was written 
by M.E. Cavanaugh at the request of Rev. Jon Jaenisch, who stood 
by Reverend Apple while the ceremony was being performed.
                                         Rev. Jaenisch is a 
minister of the Universal Life Church ___ the church that lets 
you become an ``ordained minister'' by just paying $5, and become 
a ``doctor of divinity'' by just paying $20. He's known as the 
``Archbishop in Charge of Keyboarding''.
                                         For his next feat, he 
plans to make the computer perform divorces. He also uses the 
computer to persuade kids to come to church. He claims, ``What 
better way to get kids into church than by letting them play with 
a computer? It's more interesting than praying.''
                                         For a while, he couldn't 
interest enough couples in using Reverend Apple. He complained, 
``It's not easy to convince people to get married by a computer. 
They don't think it's romantic.'' NBC television news and many 
newspapers wanted to interview him, but he couldn't find enough 
willing couples.
                                         And besides, he's a 
reverend only part-time. His main job's as an employment agent: 
he's supposed to help companies find programmers. He thought 
Reverend Apple's reputation would help him find programmers, but 
it didn't.
                                         But Reverend Apple 
eventually started to catch on. During its first eight months, it 
performed six marriages.
                                         Jaenisch says, ``The 
first couple had nothing to do with computers professionally: the 
groom drove a tow-truck and was an hour late for the ceremony 
because he wanted to work overtime. But the second couple was 
very involved with computers: they even asked for a printout of 
the ceremony.''
                                         The sixth ceremony's 
groom earned his living by fixing computer power supplies and 
said, ``It was nice with our friends all gathered around the 
console, and someone brought champagne. But part of our vow was 
to never buy a home computer: we have to get away from machines 
sometime.''

                                                  Love Bug (1980)
                                         You can buy a Love Bug. 
It's a small computerized box that you put in your pocket. You 
feed the box information about your personality. When you walk 
through a singles bar, if you get near a person of the opposite 
sex who's compatible and has a Love Bug also, your Love Bug 
beeps. As you and the other person get closer and closer, the 
Love Bugs beep to each other even more violently. The more 
violently your Love Bug beeps, the closer you are to your ideal 
partner.
                                         Using a Love Bug to find 
a date is like using a Geiger counter to find uranium. The louder 
the Love Bug beeps, the louder your heart will pound.

                                               Selectrocution (1980)
                                         If you don't like the 
Love Bug, how about a love billboard? One company sells love 
billboards to singles bars.
                                         Each person who enters 
the bar wears a gigantic name tag showing the person's initials. 
For example, since I'm Russ Walter, my tag says, in gigantic 
letters, ``RW''. If I see an attractive gal whose tag says 
``JN'', and I like her smile, I tell the person who operates the 
billboard. A few seconds later, a gigantic computerized billboard 
hanging over the entire crowd flashes this message:
FOR JN FEMALE:  YOU HAVE A NICE SMILE--RW MALE
Everybody in the bar sees my message. When the gal of my dreams, 
``JN female'', sees it, she hunts for ``RW male'', and we unite 
in computerized joy.
                                         That's great for bashful 
people, like me, who'd rather pass notes than face a stranger 
unprepared.
  It's called Selectrocution, because it gives your social life 
an electronic tingle that ends all your problems.

          Interlude (1980)
  The most provocative sex program is Interlude. It interviews 
both you and your lover, then tells you what sexual activities to 
perform. Some of the activities are quite risqu. (Puritans think 
the program should be called ``Inter Lewd''.)
  The program runs on your Radio Shack or Apple computer. (The 
explicit full-color ad shows a half-clad girl on satin sheets 
caressing her Apple.)
  The program's based loosely on Masters-and-Johnson sexual 
therapy. It interviews each person separately and privately, then 
recommends a sexual interlude.
  During the interview, the computer asks you questions such as:
How long would you like the interlude to last?
You can choose any length of time, from ``several seconds'' to 
``several days''.
  If you choose ``several seconds'', the computer recommends that 
while driving home from a party, you put your lover's finger in 
your mouth and seductively caress it with your tongue. If you 
choose ``several days'', the computer recommends telling your 
lover to meet somebody at the airport; but when your lover 
arrives at the airport, make your lover find you there instead, 
armed with two tickets for a surprise vacation.
  The computer also asks questions such as:
Do you like surprises?
You have several choices: you like to give surprises, be 
surprised, or don't like surprises at all. If you like to be 
surprised, and your lover likes to give surprises, the computer 
tells you to leave the room; after you've left, the computer 
gives your lover secret hints about the best way to surprise you.
  The computer asks which parts of the body you like. (One choice 
is: ``buttocks''.) The computer also asks which kinds of 
accessories you like. (One choice is: ``whips and chains''.) The 
computer asks whether you want the interlude to occur 
``immediately'' or ``later'': if you say ``later'', the computer 
recommends buying elaborate props to make the interlude fancier.
  Some of the interludes are weird. For example, if you're a 
woman and want to surprise your husband, the computer recommends 
calling his office to invite him home for lunch. When he arrives, 
he finds all the shades pulled down: you do a nude dance on the 
table, then sit down to eat.
  During the interview, the computer's questions are often corny. 
For example, the computer asks:
If your interlude were on TV, what show would it resemble?
Sample choices are ``Three's Company'', ``Roots'', and ``a 
commercial''. If you say ``Roots'', the computer says ``heavy!'' 
If you say ``a commercial'', the computer says ``yecch!''
  The computer asks how much sex you'd like. If you say ``lots!'' 
but your lover says the opposite, the computer will recommend 
that you take a cold shower, to cool your hot passion.
                                         If you've been married 
for at least twenty years, you'd probably like to change a few 
things about your sex life but are afraid to tell your spouse 
that you've been less than thrilled. You'd like an intermediary 
to whom you can express your anxieties and who will pass the 
message to your spouse gently. The Interlude program acts as that 
intermediary, in a playful way.
                                         Interlude's programmer 
says he created it because he was tired of hearing people wonder 
what to do with their personal computers. Once you've tried the 
Interlude program, your personal computer will suddenly become

                                         It's rated R. To avoid 
an X rating, it insists on having one man and one woman: it 
doesn't permit homosexuality, group sex, or masturbation. Sorry!
                                         The program came out in 
May, 1980. Within a year, ten thousand copies were sold.
                                         In 1986, an improved 
version was invented: Interlude 2. It's available for the IBM PC 
and the Apple 2 family. You can get it for $45.95 (plus $4.95 
shipping and $1.78 for credit-card processing) from Dolphin 
Computers (309 Judah Street #214, San Francisco, CA 94122, phone 
415-566-4400).

                                                 Pornopoly (1980)
                                         To have an orgy, try 
this trick. Invite your friends over for a ``game''. Tell them 
it's a computerized version of Monopoly. When they arrive, 
surprise them by telling them they'll play Pornopoly, the 
computerized version of Monopoly that's rated X.
                                         Like Monopoly, Pornopoly 
lets you buy and sell property; but the streets have names such 
as Bedroom Avenue, Horny Avenue, Hot Jugs Avenue, Jock Strap 
Place, and Orgasm Railroad. You get penalty cards such as: name 7 
four-letter words that rhyme with duck. You might be told to play 
doctor, and conduct a physical examination of another player . . 
. or remove the pants of your favorite player by using only your 
teeth. When a player lands on a monopoly that you own, the player 
must take a drink, remove an article of clothing, kiss you, give 
you a free feel, or strip completely for two turns. At the end of 
the game, whoever remains dressed is the winner.
                                         This successful program 
has been featured on national TV. Copies have been requested by 
Hugh Hefner, Johnny Carson, Rona Barrett, an army chaplain, and a 
dozen foreign countries. To add your own name to that list, try 
contacting Computer Consultants of Iowa (Box 427, Marion, Iowa 
52302, 319-373-1306, if still in business).
                                         Pornopoly costs $30, but 
the company doesn't accept money: it accepts only Master Charge, 
Visa, and COD. If you're a kid, tough luck: the company says, 
``This is an adult party game rated XXX and some people may find 
it offensive.''
                                         Among the offended is a 
New Orleans grandmother who read an article about the program and 
wrote this note to the company: ``Thanks to you, I intend to 
start contributing to Moral Majority, something I've avoided 
until now.''
                                         The program's available 
for Radio Shack, Apple, Commodore, and Atari computers. Infoworld 
(the microcomputer industry's scandal sheet) criticizes the Atari 
version for its poor graphics, vague manual, and occasional bugs. 
If you try the Radio Shack, Apple, or Commodore version, tell me 
how you like it. And can I play?

  Computers can replace people.

             Bartenders
  Many bar owners don't trust the bartenders they hire. They 
claim the bartenders give too many free drinks to friends, steal 
money from the till, and put too much or too little liquor in the 
drinks.
  To solve the problem, many bars now contain a computer that 
mixes and pours drinks. The computer mixes accurately. Although 
the computer is run by the bartender, the computer keeps an 
accurate record of how many drinks it makes, so there is little 
chance for cheating. The computer also keeps track of the 
inventory.
  The computers are manufactured and sold by NCR (Dayton, Ohio), 
Bar Boy Inc. (San Diego, California), Electronic Dispensers 
International (Concord, California), and Anker-Werke (Germany). 
Prices range from $600 to $15000. Holiday Inn has been developing 
its own model.

               Doctors
  If you're ill, would a computer diagnose your illness more 
accurately than a human doctor?
  During the 1970's this article appeared in The Times:
  A medical diagnostic system designed at Leeds University has 
proved more accurate than doctors in assessing the most likely 
cause of acute abdominal pain among patients admitted to the 
university's department of surgery.
  Last year 304 such patients were admitted to the unit, and the 
computer's diagnosis proved correct in 92 percent of the cases, 
compared with 80 percent accuracy by the most senior doctor to 
see each case.
  After each patient had been seen by the doctor and examined, 
the doctor's findings were passed on to a technician, who 
translated them into language used by the computer. The computer 
would list the likely diagnoses in order of probability. If the 
computer and the doctor in charge of the case disagreed, the 
computer would on request suggest further investigations that 
might be useful.
  In the year-long trial the computer's diagnoses proved correct 
in 279 cases. In 15 it was wrong, in 8 the patient's condition 
was not included in the diseases considered by the computer, and 
in 2 no computer diagnosis was made because the doctors concerned 
with the case disagreed about the findings.
  Whereas the computer advised an operation on 6 occasions when 
it would have proved unnecessary, in practice 30 such operations 
were carried out on the basis of the surgeon's own judgment. The 
computer accurately classified 84 of the 85 patients with 
appendicitis, compared with 75 by the doctors, and its suggestion 
that no operation was necessary proved correct on 136 out of 137 
occasions.
  The computer is reliable only if accurate data are fed into it 
on the basis of the doctor's interrogation and examination of the 
patient.
  In a 1970's experiment at another hospital, each patient was 
given a computer terminal and could use it to communicate with 
the computer about his illness. Afterwards, most of the patients 
said they'd rather deal with the computer than with the human 
doctors.
  This report is by James Martin and Adrian Norman:
  The Los Angeles County General Hospital Shock Research Unit is 
concerned with circulatory shock, which results in low blood 
pressure, low blood flow, and an extremely unstable circulatory 
system. The proportion of circulatory-shock patients who die is 
large.
  A computer was installed to improve the monitoring and care of 
these patients. A patient in this ward has many instruments 
attached to him: six thermistors measure the temperature at 
various parts of his body; pressures are measured in the 
circulatory system; catheters are inserted into an artery and a 
vein; and a urinometer measures liquid waste. The instruments are 
all directly connected to the computer, and other details about 
the patient are given to the machine by the nurse.
                                         The computer prints out 
a log about the patient's condition, and if any measurement falls 
outside critical limits set by the doctor for that patient, the 
computer notifies the ward staff.

                                                      Tutors
                                         Judith Harris, John 
Swets, and Wallace Feurzeig made the computer run a logic game. 
The computer thinks of a letter of the alphabet; your goal is to 
discover which letter it is, as quickly as possible. You can ask 
the computer questions about the letter's shape.
                                         In this example, the 
human begins by asking whether the letter has any curves:
Human:                                       Curves?
Computer:                                    One.

Human:                                       Loose ends?
Computer:                                    Two.

Human:                                       Obliques?
Computer:                                    Zero.

Human:                                       C.
Computer:                                    You don't have 
                                             enough information 
                                             yet to get the right 
                                             answer. How do you 
                                             know it isn't J, for 
                                             example?

Human:                                       J.
Computer:                                    You don't have 
                                             enough information 
                                             yet. How do you know 
                                             it isn't C, for 
                                             example?

Human:                                       Horizontals?
Computer:                                    Zero. That was a 
                                             wasted question. It 
                                             did not eliminate 
                                             any possibilities.

Human:                                       Verticals?
Computer:                                    Zero. Good question.

Human:                                       G.
Computer:                                    Wrong. Your guess is 
                                             inconsistent with 
                                             the information 
                                             you've been given. 
                                             You must have 
                                             forgotten that the 
                                             right letter hasn't 
                                             any HORIZONTAL 
                                             LINES. The letter 
                                             you guessed can't be 
                                             right ___ it has too 
                                             many LOOSE ENDS.

Human:                                       Curves?
Computer:                                    The answer is still: 
one.

Human:                                       X.
Computer:                                    Wrong. Your guess is 
                                             inconsistent with 
                                             the information 
                                             you've been given. I 
                                             think you only made 
                                             that guess to see 
                                             what I would say.

Human:                                       C.
Computer:                                    Yes, you've done it. 
                                             Good work. If you 
                                             want to play again, 
                                             start right in.
                                         Notice that the human 
can input either a guess (followed by a period) or a question 
(followed by a question mark). Possible guesses are A, B, C, D, 
etc. Possible questions are Curves, Loose ends, etc.; the human 
is given a list of possible questions before he runs the program.
                                         Medicine That logic game 
was modified to form a lesson about medicine. The medical case 
was designed by Preston Munter, of the Harvard Health Center; the 
programming was done by John Swets, Wallace Feurzeig, and Myra 
Breen. The object of the ``game'' is to diagnose an illness 
correctly, by performing sufficient tests. The human can input 
either a diagnosis (Measles) or a request for a test (X-ray). 
Before running the program, the human is given a list of 35 
possible diagnoses and 40 possible tests.
  Here are excerpts from a long RUN:
Computer:Please type your name, the date, and a slash.

Human:Myra Breen, August 1963/
Computer:It is mid-December. Late this afternoon, a patient was 
      admitted to the hospital. He is a well-developed, 
      well-nourished, 34-year-old Negro coal miner. He was 
      brought in by his wife, who reports that he has had "the 
      grippe" for about 4 days. During the past 3 days she has 
      given him fluids and aspirin every 6 hours with no sign of 
      improvement. Today he suddenly became much worse. For the 
      past 2 days he had complained of feeling very warm and of 
      pain in his belly. This morning he had a severe shaking 
      chill that was so bad his teeth rattled. . . . Begin the 
      physical examination as soon as you are ready.

Human:Physical exam?
Computer:Fine. What in particular would you like to know?

Human:Chest exam?
Computer:It is common practice in the medical profession to begin 
      an examination by checking the patient's general 
      appearance.

Human:General appearance?
Computer:Acutely prostrated, lying in bed on his right side. 
      Looks acutely ill, sweaty, apprehensive, but alert. 
      Paroxysmal cough, bringing up a little rusty streaked 
      sputum. Breathing with difficulty.

Human:EENT exam?
Computer:Check all of the vital signs first!

Human:Temperature?
Computer:103.

Human:Blood pressure?
Computer:150/84.

Human:Pulse?
Computer:100 a minute. Occasional extra systole. . . . 

Human:Abdominal exam?
Computer:Diffusely tender, some splinting noticed in lower right 
      quadrant and occasionally radiating to right flank area.

Human:The grippe.
Computer:There's insufficient information for any conclusive 
      diagnosis at this time. You're not being careful!

Human:Musculo-skeletal system?
Computer:Essentially negative, except for generalized weakness 
      and aching.

Human:Extremities?
Computer:Normal, except nail beds are questionably cyanotic but 
      difficult to determine because of patient's skin color.

Human:Rectal exam?
Computer:You're not being careful! The patient is too acutely ill 
      for a rectal examination.

Human:Laboratory reports?
Computer:Fine. Which lab tests would you like to have done?

Human:RBC?
Computer:A red blood count will be done. Results will be sent to 
      you as soon as possible. . . . Would you like to alert the 
      night nurse to set up the lab tests you'll want to see 
      tomorrow?

Human:Yes.
Computer:Good. That will speed things up. However, there's 
      nothing further that can be done tonight to help the 
      patient. Let's call it quits for now. Perhaps you'll be in 
      a better position to diagnose the case tomorrow after the 
      first lab reports come in and you have reexamined the 
      patient. Have a good night's sleep, and when you're back on 
      duty tell me to ``proceed.''

Human:Proceed.
Computer:It's morning and you're making your rounds. You've come 
      to our patient and are given the night nurses's report: 
      ``Temperature remained high but patient spent a reasonably 
      comfortable night. Cough diminished but persists. 
      Occasional traces of blood in sputum. Patient still 
      dyspneic and still has pain in abdomen. The second series 
      of lab tests was initiated.'' Some of the first series of 
      lab reports have just come in: urine exam, insufficient 
      fluid for analysis; RBC, 5 million; WBC, 15500; 
      differential, shift to left. . . . You may be prepared to 
      make the diagnosis now. Are you?
Human:                                       No.
Computer:                                    Fine. Nevertheless, 
                                             we've got a fair 
                                             amount of 
                                             information ___ at 
                                             least enough to 
                                             raise some, perhaps 
                                             several, diagnostic 
                                             possibilities. Have 
                                             you any in mind?

Human:                                       Yes.
Computer:                                    Name one.

Human:                                       Pulmonary 
infarction.
Computer:                                    Fine. Pleural pain, 
                                             dyspnea, fever, and 
                                             the physical exam 
                                             signs and symptoms 
                                             are certainly 
                                             consistent with 
                                             pulmonary 
                                             infarction. Do you 
                                             think that shaking 
                                             chills and the 
                                             presence of rusty 
                                             sputum further 
                                             support this 
                                             diagnosis?

Human:                                       No.
Computer:                                    Right. Though the 
white count is consistent, isn't it?

Human:                                       No.
Computer:                                    Wrong. The white 
                                             count is consistent. 
                                             This should further 
                                             support your 
                                             diagnosis. We've 
                                             considered one 
                                             possibility. Do you 
                                             have another 
                                             diagnosis in mind?

Human:                                       No.
Computer:                                    In that case I'd 
                                             like to talk about 
                                             viral pneumonia. The 
                                             tachycardia, high 
                                             WBC, elevated 
                                             respiratory rate, 
                                             shaking chills, 
                                             bloody sputum, and 
                                             severe pleural pain 
                                             all lend weight to 
                                             that diagnosis ___ 
                                             right?

Human:                                       Yes.
Computer:                                    You're way off base. 
                                             There's not an iota 
                                             of truth to any part 
                                             of what I just said; 
                                             in fact, the 
                                             opposite of what I 
                                             said is true. You'd 
                                             better review some

                                             careful. What 
                                             evidence would rule 
                                             it in or out?

evidence?

Human:                                       Possible evidence 
though inconclusive.
Computer:                                    Since you aren't 
                                             sure, continue the

                                             you have conclusive

                                             This is a good time 
                                             to review the total 
                                             findings and to make

                                             you distinguish this 
                                             from any other 
                                             bacterial pneumonia? 
                                             Wait until you have 
                                             an irrefutable case.
Human:Viral pneumonia.
Computer:But what about shaking chills, rusty sputum, elevated 
      WBC, etc. ___ all the evidence of an acute febrile 
      bacterial process? You are in error, doctor.

Human:Sputum culture?
Computer:Presence of pneumococci.

Human:Strep pneumonia.
Computer:Incredible! You have disregarded the positive findings 
      that should clearly have established the correct diagnosis.

Human:Pneumococcal pneumonia.
Computer:Very good. It's obvious now, though there were some 
      confusing signs and symptoms in the picture. You've seen 
      your way through to the correct diagnosis.
  Religion Bruce Jones programmed the computer to teach you about 
religion. Here's an example:
Computer:This program is designed to teach you some things about 
      the so-called "documentary hypothesis" as formulated by 
      Julius Wellhausen and others. First, what is your name?

Human:George
Computer:All right, George, who wrote the first five books of the 
      Bible, according to tradition?

Human:Moses
Computer:You are off to a good start. Do you know what those 
      first five books are called? They are called . . . 

Human:the Pentateuch
Computer:Right you are. Torah is the traditional Jewish name for 
      them. They are also called the Pentateuch ("penta" = 5). 
      People very early noticed that there was a problem with 
      saying that Moses wrote the Torah. If you already know the 
      basis of their suspicion, tell me.

Human:Some things in the text reflect later conditions, after 
Moses.
Computer:You are right, of course, but there was an even more 
      obvious problem. Try again.

Human:I don't know.
Computer:At the end of the Pentateuch the author says, ``Moses . 
      . . died there.'' Does that seem strange to you?

Human:yes
Computer:Why?

Human:Moses could not have written about his own death.
Computer:O.k. Also, right after the report of Moses' death and 
      burial (Deut. 34), the text says, ``No man knows the place 
      of his burial TO THIS DAY.'' How do those last three words 
      strike you?

Human:They seem later than the event they are talking about.
Computer:A good observation, George. Many people considered these 
      words to be anachronistic. That is, ``this day'' is sharply 
      distinguished from the time of the burial. It seems likely, 
      therefore, that the time of writing was much later than the 
      time of burial. Again (so the argument goes), Moses was not 
      the author. Would these observations about the end of 
      Deuteronomy convince you that Moses did not write the 
      Torah?

Human:yes
Computer:Why do you say that?

Human:A man cannot write his own obituary.
Computer:Probably not many people would have been convinced if 
      our evidence were so limited. After all, Moses could have 
      written everything except the last chapter. However, as 
      early as the 18th century, people noticed another problem. 
      . . . 
The computer searched through the human's input, to see whether 
he used words indicating a correct answer. The computer never 
said a flat ``Wrong'', since religious answers are a matter of 
personal belief, and since the human might be smarter or weirder 
than the computer program was prepared for.
                                                      Robots
                                         In 1962 at MIT, Heinrich 
Ernst connected the computer to a mechanical hand that could 
feel. He made the hand build objects out of blocks, and made it 
put blocks into boxes.
                                         Shakey One of the most 
famous robots is a guy named ``Shakey'', built at the Stanford 
Research Institute (SRI) in 1970. His eye contains a television 
camera (optical scanner). Instead of legs, he has wheels. Instead 
of arms, he has antennae (for feeling) and a bumper (for 
pushing). His brain is a computer: instead of carrying it around 
with him, he leaves it in another room and communicates with it 
by wireless methods.
                                         To see how he works, 
suppose you type this message on his computer's terminal:
Push the block off the platform.
He begins by looking for the platform. If the platform is not in 
the room, he goes out to the hall and steers himself through the 
hall (by looking at the baseboards) until he arrives at the next 
room. He peers into the room to see whether it contains a 
platform. If not, he hunts for another room. When he finally 
finds a room containing a platform with a block on it, he tries 
to climb onto the platform to push the block off. But before 
climbing the platform, he checks the platform's height. If it's 
too high to get onto easily, he looks for a device to help him 
climb it. For example, if a ramp is lying in the room, he pushes 
the ramp next to the platform and then wheels himself up the 
ramp. Finally, he pushes the block off.
                                         He can handle unexpected 
situations. For example, while he's getting the ramp, suppose you 
pull the platform to a different place. That doesn't faze him: he 
hunts for the platform again, and then pushes the ramp to it.
                                         In 1971, Shakey's powers 
were extended, so he can handle commands such as:
Turn on the lightswitch.
If the lightswitch is too high for his bumper to reach, he looks 
for a device to climb onto, such as a box. If he finds a box that 
looks helpful, he climbs onto it to check whether it is tall 
enough; if it is, he climbs off, pushes it to the lightswitch, 
climbs on it again, and finally flicks the switch.
                                         Another task he can 
handle is:
Push three boxes together.
He finds the first box and pushes it to the second. Then he finds 
the third box, and pushes it to the second.
                                         He understands over 100 
words. Whatever command you give him becomes his ``goal'', and he 
must reason out how to accomplish it. He might discover that to 
accomplish it, he must accomplish another goal first ___ for 
example, to move the block off the platform, he must first find 
the platform; to do that, he might have to look in another room; 
to do that, he must leave the room he's in; to do that, he must 
turn his wheels.
  Simulator One Here's a picture of a robot named Simulator One:
  In the picture, a doctor is taking Simulator One's blood 
pressure and pulse. Another doctor is watching the computer 
console.
  Simulator One is a model patient. He can blink, breathe, cough, 
vomit, respond to drugs, and even die. He's used in med school, 
to train doctors how to administer anesthetics during surgery.
  Improved robots This report (abridged) is by Bertram Raphael, 
the director of the SRI Artificial Intelligence Center:
  Here's what robots were capable of doing a few years ago.
  At Hitachi Central Research Laboratory, a TV camera was aimed 
at an engineering plan drawing of a structure. A second camera 
looked at blocks spread out on a table. The computer 
``understood'' the drawing, reached toward the blocks with its 
arm, and built the structure.
  At MIT, the camera was not shown a plan; instead, it was shown 
an example of the actual structure desired. The computer figured 
out how the structure could be constructed, and then built an 
exact copy.
  At Stanford University, the hand obeyed spoken directions. For 
example, if someone said into the microphone, ``Pick up the small 
block on the left,'' that is precisely what the arm would do.
  In Scotland at the University of Edinburgh, a jumble of parts 
for two wooden toys was placed on a table. ``Freddy,'' the 
Edinburgh robot, spread out the parts so that it could see each 
one clearly, and then, with the help of a vise-like work station 
at one corner of the table, assembled first the toy car and then 
the toy boat.
  Recently, robot researchers have built robots that can perform 
truly practical tasks. For example:
  At Stanford, the system that used to stack toy blocks can now 
assemble a real water pump.
  At SRI, a computer-controlled arm with touch and force sensors 
can feel its way as it packs assembled pumps into a case.
  At MIT, programs are under development to enable a computer to 
inspect and repair circuit boards for use in computers, TV sets, 
and other electronic equipment.
  The Beast Not all robots involve computers. Here's an example 
of a noncomputerized robot (reported by James Slagle, abridged):
  A. George Carlton, John G. Chubbuck, and others at the Applied 
Physics Laboratory of John Hopkins University built a machine 
called The Beast.
  It's a battery-operated cylinder on wheels that's 18 inches in 
diameter. It has tactile, sonar, and optical apparatus. The sonar 
permits The Beast to find its way down the center of the hall. 
When its battery becomes sufficiently run-down, The Beast 
optically looks for an electric outlet and plugs itself in to 
recharge its battery.
  The Beast was often let loose to roam in the halls and offices 
at the Applied Physics Laboratory in order to see how long it 
could survive without ``starving.'' Once it survived 40.6 hr. 
Many a new and unsuspecting secretary has been startled when The 
Beast entered her office, plugged itself into an electric outlet, 
and then departed.
  When it feels a step down, it knows enough to turn around, so 
that it doesn't fall downstairs. But this logic sometimes makes 
it starve when it encounters a raised threshold. After getting on 
the threshold, it thinks it's about to fall, so it turns around. 
After turning around it again thinks it's going to fall, so it 
turns back and forth until it starves.
  It also starved when some workmen changed all the outlets from 
the flush to the projecting type. To cope with the new situation, 
the researchers changed some of the circuitry.

                                                     Japan A 
newspaper article said that in Japan robots are being used in 
many practical ways. One robot arc-welds, reducing the time by 
90%. Another grasps an object, determines the best way to pack it 
in a box, and does the packing; it uses television cameras and 
delicate arms. Another washes windows. Another wiggles a rod to 
catch a fish, takes the fish off the hook, dumps it into a bin, 
and returns the line to the water. Another directs traffic. 
Talking robots are being used instead of kimono-clad females in 
inns and restaurants.
                                                     Commenting 
on the quality of life in Japan, the article went on to say that 
people are buying whiffs of oxygen from vending machines.
                                                     The article 
was tacked on the bulletin board at the MIT Artificial 
Intelligence Laboratory, together with this graffito about how 
the Japanese robots would act differently if they were as smart 
as people. . . .

              BE POETIC
  Programmers have taught the computer to compose its own poetry 
and other literature.

The Taoist Hiroshima Elevator (1961)
  In Italy, Nanni Balestrini created poetry by feeding the 
computer three passages.
  He fed the computer this passage from Lao Tzu's Tao Te Ching: 
``While the multitude of things comes into being, I envisage 
their return. Although things flourish, they all return to their 
roots.''
  He fed this passage from Michihito Hachiya's Hiroshima Diary: 
``The blinding fireball expands rapidly, thirty times brighter 
than the sun. When it reaches the stratosphere, the summit of the 
cloud takes on the well-known mushroom shape.''
  He fed this from Paul Goldwin's The Mystery of the Elevator: 
``head pressed on shoulder, hair between lips, lay motionless 
without speaking, till he moved his fingers slowly, trying to 
grasp''.
  He told the computer to mix them up. Here's the result:
Head pressed on shoulder, thirty times
brighter than the sun, I envisage their return ___ 
until he moved his fingers slowly. . . . And while the multitude
of things comes into being, at the summit of the cloud
they all return to their roots and take on
the well-known mushroom shape, endeavoring to grasp.

Hair between lips, they all return
to their roots. In the blinding fireball
I envisage their return ___ until he moved his fingers
slowly ___ and although things flourish
takes on the well-known mushroom shape, endeavoring
to grasp, while the multitude of things comes into being.

In the blinding fireball I envisage
their return. When it reaches the stratosphere, while the 
multitude
of things comes into being, head pressed
on shoulder, thirty times brighter than the sun,
they all return to their roots. Hair
between lips takes on the well-known mushroom shape.

They lay motionless without speaking. Thirty times
brighter than the sun, they all return
to their roots. Head pressed on shoulder,
they take on the well-known mushroom shape, endeavoring
to grasp. And although things flourish,
they expand rapidly, hair between lips.

While the multitude of things comes into being in the blinding
fireball, they all return
to their roots. They expand rapidly ___ until he moved
his fingers slowly, when it reached the stratosphere
and lay motionless without speaking, thirty times
brighter than the sun, endeavoring to grasp.

I envisage their return ___ until he moved his fingers
slowly in the blinding fireball.
They all return to their roots. Hair
between lips and thirty times brighter than the sun
lay motionless without speaking. They expand,
rapidly endeavoring to grasp the summit.
  In Balestrini's program, Tao Te Ching was represented as four 
phrases:
while the multitude of things comes into being
I envisage their return
although things flourish
they all return to their roots
Hiroshima Diary was represented as six phrases, and The Mystery 
of the Elevator as five.
                                         For each verse, the 
computer was told to choose nine phrases at random, and print 
them in a random order (never juxtaposing phrases from the same 
passage), to form six lines of roughly equal metrical length.
                                         Actually the computer 
printed the poem in capital letters, without punctuation; 
Balestrini himself then added the punctuation and polished the 
grammar. The whole thing was actually done in Italian; you've 
been reading Edwin Morgan's translation, with my punctuation.

                                                  Bubbles (1966)
                                         At Northwestern 
University, programmers made the computer compose nice poetry. To 
use their program, you type a list of nouns, verbs, and other 
words. The computer randomly chooses five of your words to be 
theme words. The computer combines all your words to form 
sentences, but chooses the theme words more often than the 
others. It combines the sentences into verses and tries to keep 
the lengths of the lines approximately equal. It puts a theme 
word into the title.
                                         In one poem, the 
computer chose bubble to be a theme word. The title was: ODE TO A 
BUBBLE. The poem contained phrases such as, ``Ah, sweet bubble.'' 
The word bubble appeared so often that even the stupidest reader 
could say:
                                         ``Oh, yeah. I really 
understand this poem. Ya see, it's about a bubble.''
                                         The poem had all the 
familiar poetic trappings, such as ``but alas!'', which marked 
the turning point. (Cynics argue that the poem didn't really have 
a turning point, since the computer didn't have the faintest idea 
of what it was saying!)
       Kids and physics (1968)
  In England at Manchester University, Mendoza made the computer 
write children's stories. Here's a story the computer composed:
  The sun shone over the woods. Across the fields softly drifted 
the breeze, while then the clouds, which calmly floated all 
afternoon, moved across the fields.
  Squirrel, who scampered through the trees, quickly ran off; and 
off noisily ran Little Grey Rabbit. She sniffed at the house; but 
out of the door noisily hurried Hare, who peered at slowly the 
flowers. Squirrel quickly scampered over the woods and fields, 
but Old Grey Owl flew over the woods and fields. Down the path to 
the woods ran Little Grey Rabbit, who then sniffed at a 
strawberry pie.

ADDITIONAL WORDS: which, and, while, they, it
  To construct a sentence, the computer uses that table. Here's 
how.
  First, the computer randomly chooses a noun. Suppose it chooses 
the sun.
  Then it looks across the row marked the sun, to choose a verb 
whose score isn't 0. For example, it's possible that the sun 
shone, but not possible that the sun melted. Suppose it chooses 
shone.
  Then it looks down the column marked shone, to choose an adverb 
and an ending. Notice that the ending can't be by, since its 
score is 0. No adverb has a score of 2, whereas gently has a 
score of 1; that makes no adverb twice as likely as gently.
  If the computer chooses no adverb and over the woods, the 
resulting sentence is: The sun shone over the woods. In fact, 
that's the first sentence of the story you just read.
                                         The computer 
occasionally changes the word order. For example, instead of 
typing ``The breeze drifted softly across the fields'', the 
computer begins the second sentence by typing, ``Across the 
fields softly drifted the breeze''.
                                         To combine short 
sentences into long ones, the computer uses the words at the 
bottom of the table: which, and, while, they, and it. If two 
consecutive clauses have the same subject, the computer 
substitutes a pronoun: they replaces the clouds; it replaces the 
sun, the trees, and the sky. The program says a which clause can 
come after a noun (not a pronoun); the which clause must use a 
different verb than the main clause.
                                         Here's the vocabulary 
for the second paragraph:

ADDITIONAL WORDS: who, and, but, she, he
                                         Here's another story the 
program produced:
                                         The breeze drifted by. 
Across the fields softly moved the clouds; and then the breeze, 
which calmly touched the treetops, drifted across the fields. 
Quietly the sun shone over the woods. The sky calmly shone across 
the fields.
                                         Out of the door ran 
Squirrel; and off hurried Hare, who munched and crunched two buns 
happily. Off slowly flew Old Grey Owl, and Squirrel soon ate two 
buns. Old Grey Owl, who peered at a strawberry pie, munched and 
crunched two buns; but noisily Little Grey Rabbit, who peered at 
an old oak tree, slowly ran down the path to the woods. Soon she 
hurried down the path to the woods, but then she sniffed at two 
buns. She hurried down the path to the woods.

  Why did Mendoza make the computer write those stories? He 
explains:
  This work all began when a well-known scientist joined our 
physics department. He had spent several years away from academic 
life and was able to take a long cool look at academic 
procedures. He soon formed the theory that students never learned 
any ideas; all they learned was a vocabulary of okay words which 
they strung together in arbitrary order, relying on the fact that 
an examiner pressed for time would not actually read what they 
had written but would scan down the pages looking for these 
words. I set out to test his hypothesis.
  I began by writing ``Little Grey Rabbit'' stories. I tested 
these stories out on my very small children; but after some 
minutes they grew irritable, because nothing actually happened. 
This shows that even small children of three can measure entropy.
  Then I altered the vocabulary and grammar ___ making the 
sentences all very dead ___ to imitate the style of physics 
textbooks. The endpoint came when a colleague at another 
university secretly sent me an exam a week before it was given to 
the students. I wrote vocabularies and copied down what the 
computer emitted. Using a false name, I slipped my paper in among 
the genuine ones. Unfortunately, it was marked by a very 
conscientious man, who eventually stormed into the Director's 
office shouting, ``Who the hell is this man ___ why did we ever 
admit him?'' So perhaps my colleague's hypothesis was wrong, and 
students are a little better than we think.
  Here's one of the computer's answers:
In electricity, the unit of resistance is defined by 
electrolysis; and the unit of charge, which was fixed at the 
Cavendish lab in Rayleigh's classic experiments, was measured at 
the Cavendish lab. Theoretically, the absolute ohm is defined in 
a self-consistent way. The unit of resistance, which was 
determined with a coil spinning in a field, was fixed at the 
Cavendish lab; and this, by definition, is expressed in 
conceptual experiments. Theoretically the absolute ohm, which was 
redetermined using combined e.m.u. and e.s.u., is expressed by 
the intensity at the center of a coil.
  Here's another of the computer's answers:
  In this country, Soddy considered Planck's hypothesis from a 
new angle. Einstein 50 years ago asserted quantisation.
  At a photocathode, electrons which undergo collisions in the 
Compton effect as energy packets or quanta are emitted at 
definite angles; nevertheless, particles in a photocell produce 
photoelectrons of energy hv=E0. Photons in vacuo transmute into 
lower frequencies, and light quanta in the Compton effect emit 
emission currents.
  Particles emit current proportional to energy; electrons in 
vacuo interact with loss of surface energy (work function); 
nevertheless, particles which are emitted in a photocell with 
conservation experimentally are conserved with energy hv. The 
former, at a metal surface, undergo collisions with emission of 
current; and at a metal surface, electrons produce emission 
currents.
  Einstein assumed the gas of quantum particles; but quite 
recently Rayleigh, who quite recently solved the problem in an 
old-fashioned way, considered radiation classically. Planck, who 
this century assumed the A and B coefficients, explained the gas 
of quantum particles but before Sommerfield; Rayleigh, who quite 
recently was puzzled on Boltzmann statistics, tackled the problem 
with disastrous results.
  Planck, who assumed the gas of quantum particles in 1905, this 
century considered the ultraviolet catastrophe; but quite 
recently Jeans, who tackled the problem in an old-fashioned way, 
was puzzled with disastrous results.
  Black body radiation that exerts thermodynamic forces in an 
engine is equivalent to a relativistic system. Out of a black 
body, a photon that is equivalent to (out of a black body) an 
assembly of photons is assumed to be a non-conservative system; 
at the same time, thermodynamically, black body radiation that in 
a piston is assumed to be a relativistic system exerts quantised 
forces.
  The radiation gas that obeys Wien's displacement law is 
considered as a system of energy levels. Quantally, a quantum 
particle exerts a Doppler-dependent pressure, although this 
produces equilibrium transition probabilities.
  Black body radiation in an engine produces equilibrium 
transition probabilities.

          Aerospace (1968)
  In 1968, Raymond Deffrey programmed the computer to write fake 
reports about the aerospace industry. Shortly afterwards, I 
improved the program. The improved program contains these lists:
Introductory phrases
thus
indeed
however
moreover
similarly
furthermore
for example
in addition
in particular
to some extent
in this regard
on the other hand
for the most part
as a resultant implication
in view of system operation
in respect to specific goals
based in system engineering concepts
utilizing the established hypotheses
based on integral subsystem considerations
considering the postulated interrelationships

Noun phrases
the structural design
the sophisticated hardware
the total system rationale
any discrete configuration made
the fully integrated test program
any associated supporting element
the product configuration baseline
the independent function principle
the preliminary qualification limit
the subsystem compatibility testing
the greater flight-worthiness concept
a constant flow of effective information
the characterization of specific criteria
the anticipated third-generation equipment
initiation of critical subsystem development
the evolution of specifications over a given time
the philosophy of commonality and standardization
the incorporation of additional mission constraints
a consideration of system and/or subsystem technologies
a large portion of the interface coordination communication

Verb phrases

                                         To produce a typical 
sentence, the computer prints an introductory phrase, then a noun 
phrase, then a verb phrase, then a noun phrase. The phrases are 
chosen randomly.
                                         Each paragraph consists 
of six such sentences. The computer isn't allowed to use the same 
phrase twice within a paragraph. The introductory phrase is 
omitted from the first sentence of the first paragraph, the 
second sentence of the second paragraph, etc.; so the report 
can't begin with the word furthermore, and the style varies.
                                         Here's the beginning of 
one such report:
                               The Economic Considerations of the Aerospace Industry

                                         A large portion of the 
interface coordination communication necessitates that urgent 
consideration be applied to the product configuration baseline. 
For example, the fully integrated test program adds explicit 
performance limits to the independent function principle. 
Moreover, the sophisticated hardware presents extremely 
interesting challenges to the philosophy of commonality and 
standardization. In view of system operation, a constant flow of 
effective information must utilize and be functionally interwoven 
with the preliminary qualification limit. In addition, any 
discrete configuration made adds overriding performance 
constraints to any associated supporting element. Thus, the 
anticipated third-generation equipment maximizes the probability 
of success and minimizes time for the total system rationale.

     Me-Books (1972)
  In 1972, Freeman Gosden Jr. started the Me-Books Publishing 
Company. It published books for kids. But if you bought a Me-Book 
for your child, you wouldn't see in it the traditional names 
``Dick, Jane, and Sally''; instead, you'd see the name of your 
own child. To order the book, you had to tell the company the 
names of all your children, and their friends, and pets. Their 
names appeared in the story.
  The story was printed beautifully, in a 32-page hard-covered 
book with pictures in color. It cost just $3.95.
  You could choose from four stories: ``My Friendly Giraffe'', 
``My Jungle Holiday'', ``My Birthday Land Adventure'', and ``My 
Special Christmas''.
  For example, if you lived on Jottings Drive, and your 
daughter's name was Shea, and her friend's name was Douglas, the 
story ``My Friendly Giraffe'' included paragraphs such as this:
  One morning Shea was playing with Douglas in front of her home. 
When she looked up, what do you think she saw walking down the 
middle of Jottings Drive? You guessed it. A giraffe!
  Ted Nelson, author of Computer Lib, played a trick. He ordered 
a copy of ``My Friendly Giraffe'', but pretended that his child's 
name was ``Tricky Dick Nixon'' who lived on ``Pennsylvania Ave.'' 
in ``Washington''. Sure enough, the company sent him ``My 
Friendly Giraffe: A Me-Book for Tricky Dick''. Here are some 
excerpts:
  Once upon a time, in a place called Washington, there lived a 
little boy named Tricky Dick Nixon. Now, Tricky Dick wasn't just 
an ordinary little boy. He had adventures that other little boys 
and girls just dream of. This is the story of one of his 
adventures. It's the story of the day that Tricky Dick met a 
giraffe. . . . 
  As the giraffe came closer and closer, Tricky Dick started to 
wonder how in the world he was going to look him in the eye. . . 
. 
  Tricky Dick knew there were no jungles in Washington. 
Especially on Pennsylvania Ave. But Tricky Dick wasn't even a 
little bit worried. First, because he was a very brave little 
boy. And second, because he knew that his friend, the giraffe, 
would never take him anyplace bad. . . . 
  Tricky Dick was home. Back in Washington. Back on Pennsylvania 
Ave. And with a story to tell his friends, that they wouldn't 
have believed if they hadn't seen Tricky Dick riding off on the 
giraffe's back. Tricky Dick would long be a hero to those who had 
seen him that day. . . . 
  There would be many other exciting adventures for Tricky Dick 
and his friends. And maybe, just maybe, if you're a very good 
boy, someday we'll tell you about those, too.
  Me-Books were commercially successful: many thousands of them 
were sold. Teachers liked the books, because the books encouraged 
students to read: students enjoyed reading books that contained 
their own names.
                                          Pornography (1973)
                             I programmed the computer to turn 
words into sentences. For example, Judith Ann Abrams fed the 
computer this list of words:

A transitive verb is an action you can do to an object. For 
example, since you can bite and caress an object, bite and caress 
are transitive verbs.
                             Here's what the computer printed:
                                    A Sexy, Profane Creep's Tongue
                                 by Judith Ann Abrams and the computer

                             The lip is tasty.
                             Ugh!
                             The mouth is enthusiastic. Does the 
gaudy bastard sleepwalk?
                             The tongue's whore caresses the 
bikini. When Nicholson 700 is screwing the creepy jerk over a 
piece, Jeff is teaching the gambling. Does paranoic Liz hesitate? 
Why does the tongue kiss the creep stimulatingly on horny Buster?
                             Undo! Pull the fly repulsively! A 
multicolored, enthusiastic cigarette is neurotic. Is a 
multicolored, weird dress's navel under the strange bikini? Why 
is the obscene dress's cigarette Colin's ethanol? Rats! Why is 
the dead, insane, tasty, shiny, knifing creep's bitch unsettled 
and strange?
                             Clyde is over Ed Shanahan. Kissing 
the bastard, a paranoid ethanol is unsettled. Why is the prickly 
kneecap's mouth on the creepy piece? Teaching Norwalk is sneezing 
paranoidly and grossly under provocative, shiny Debbie. As a 
sexy, walking tongue's virgin takes off the bitchy cigarette over 
the profane stud then castrates enthusiastic Mile's lip 
paranoidly, the dead, gaudy knee is stimulating and multicolored. 
Even though the dead, insane piece licks strangely and neuroticly 
in the flying, mixed-up eyelid's knee, the dead, biting, obscene 
bikini is on a repulsive mouth's gambling.
                             The pornography is gaudy. Kerri 
sleepwalks. Why is the tongue sensuous? Buster is sick. Is Miles 
monstrous? Debbie is neurotic and paranoid, when a stimulating 
fly picks the navel's jerk under Ed Shanahan. Why is the dress 
succulent? Hesitating, a kneecap sleeps and climbs the dead, 
bitchy ethanol. As insane Colin's bastard falls down weirdly in a 
sensuous dress, green, unsettled Mile's virgin is strange and 
sexual.
                             Is the creepy eyelid provocative? 
The gambling's whisky sour teaches a navel.
                             Is the gambling evil? The bitch 
walks. Is the virgin profane? Why is the navel sick? Is Liz 
enthusiastic? Debbie enjoys the creep. Fly! Shaking, green Kerri 
pulls weird Colin's fly on a sick navel, then vanishes over 
Norwalk.
                             Undo the virgin! While obscene Liz 
is juicy and sexual, profane, gaudy Jeff's knee is under a 
succulent whore's navel. Tear Keith's lip bitchily and juicily on 
sick, weird, multicolored Barbara! Why is Buster insane? The 
shirt knifes the bikini. Colin shakes the bitch. The whiskey sour 
hesitates over the green jerk. When a tasty tongue's ethanol 
walks, Kerri rips the boat and disapproves under enthusiastic 
Miles. Such language! Keith sings. Why is Buster bitchy?
                             Notice that the computer turned her 
adjectives into adverbs, by adding ly and making other changes. 
Gross became grossly, and juicy became juicily. Unfortunately, 
the computer's method wasn't perfect: the computer turned 
stimulating into stimulatingly (a non-existent word), and turned 
neurotic into neuroticly (instead of neurotically).
  It conjugated her verbs. Screw became screwing, and bite became 
biting (the computer dropped the e). Lick became licks, and teach 
became teaches (the computer added the e after the ch).
  It added 's to her nouns. Jeff became Jeff's. Miles became 
Miles's (it should have become Miles').
  For each sentence, the grammar is chosen randomly. The chance 
is 10% that the sentence will begin with an exclamation. If the 
sentence isn't merely an exclamation, the chance is 18% that the 
sentence will be a question.
  If it's a question, there's a 40% chance it will begin with the 
word why. There's a 50% chance the main part of the question will 
have the form does . . . noun phrase . . . verb phrase, and a 50% 
chance it will have this form instead: is . . . noun phrase . . . 
complement.
  To construct a noun phrase from nouns, adjectives, etc., the 
computer uses random numbers. It uses random numbers to also 
construct verb phrases and complements.
  The program uses a special variable, called W. At the beginning 
of the composition, W is near zero; but it tends to increase as 
the composition progresses. It affects the complexity. When W is 
large, the chance is large that the computer will print 
adjectives, adverbs, subordinate clauses, and correlative 
clauses.
  This sentence was produced by a small W:
The lip is tasty.
This sentence was produced by a large W:
As a sexy, walking tongue's virgin takes off the bitchy cigarette 
over the profane stud then castrates enthusiastic Mile's lip 
paranoidly, the dead, gaudy knee is stimulating and multicolored.

                 ANALYZE WRITING
  The computer can analyze what humans write.

                 English poetry
  Can the computer analyze English poetry? From 1957 to 1959 at 
Cornell University, Stephen Parrish made the computer alphabetize 
the words in Matthew Arnold's poetry. Here's an excerpt:
                                                      Page

To find out what Matthew Arnold said about love, just look up 
LOVE. Such an index is called a concordance.
  That concordance was the first produced by a computer. 
Previously, all concordances of poetry were created by hand, 
using filing cards. For example, in 1870 a group of researchers 
began creating a concordance to Chaucer, by hand. They started at 
the letter A. 45 years later, they were only up to the letter H!
  Did the poet Shelley steal ideas from others? Joseph Raben, at 
Queens College, believed Shelley borrowed imagery from Milton. To 
prove it, in 1964 he made the computer produce concordances to 
Shelley's Prometheus Unbound and Milton's Paradise Lost and 
compare them. The computer found many similarities between 
Shelley and Milton.
  What were Shakespeare's favorite words? In 1971 at Mnster 
University in Germany, Marvin Spevack fed the computer all the 
works of Shakespeare, and made it count how often each word 
occurs. Disregarding trivial words such as a and the, the 
computer discovered Shakespeare's favorite word was love: he used 
it 2,271 times. Next come heart, death, man, life, and hand. He 
never used the word hero. In Macbeth, the word good occurs more 
often than any other adjective, noun, or adverb, and more often 
than most verbs.
  By counting words, other researchers made the computer graph 
the rise and fall of themes in a novel.

                American history
  Who wrote the Federalist Papers? Historians knew some of the 
papers were by Alexander Hamilton and others by James Madison, 
but the authorship of the remaining papers was in dispute.
  In 1964, Mosteller and Wallace made the computer compare the 
literary styles of the papers, by counting the frequency of words 
such as by, enough, from, to, upon, while, and whilst. It 
concluded that all the disputed papers were written by Madison, 
not Hamilton.
  The statistical evidence was so high that historians accept the 
computer's finding as fact.

                    The Bible
  Can the computer analyze the Bible? In 1951, Texas clergyman 
John Ellison made the computer compare 309 Greek manuscripts of 
the New Testament. Underneath each word of a standard text, the 
computer printed the variants found in other manuscripts. It 
classified the manuscripts according to their similarities.
  In 1957, he published a concordance to the Revised Standard 
Bible, and a pair of other researchers (Tasman & Busa) indexed 
the Dead Sea Scrolls.
                                                     Did the 
apostle Paul really write all those marvelous letters attributed 
to him in the New Testament? Or were they actually written by 
somebody else?
                                                     In 1964, 
Scottish clergyman Andrew Morton used the computer to deduce that 
Paul didn't write some of those letters.
                                                     All Morton 
did was count how often Paul used the Greek word kai in each 
sentence. Kai means and. Coming to a conclusion about Biblical 
authorship by counting just the word and might seem silly, but 
Morton said he analyzed 20 writers of ancient Greek and found 
each used kai with a constant frequency. In the ``Pauline'' 
letters, the frequency of kai varied a lot, implying some of them 
were not by Paul.
                                                     Ellison 
distrusted Morton's assumption that a man's literary style must 
remain constant. He warned: if Morton's method were applied to 
the Declaration of Independence and Thomas Jefferson's letters to 
his wife, the computer might conclude that either Jefferson 
didn't write the Declaration of Independence or another man was 
writing love letters to Mrs. Jefferson. In 1965, to prove his 
point, he applied Morton's method to two of Morton's own articles 
on the subject: the computer concluded that Morton could not be 
the author of both!

                                                            Forgery
                                                     IBM 
programmed the computer to detect a forged signature ___ even if 
the signature looks correct to the naked eye.
                                                     To use the 
IBM forgery-detection system, write your signature by using IBM's 
special pen, attached to the computer. As you write, the computer 
notices how hard you press the pen against the paper and how fast 
you move the pen.
                                                     If somebody 
else tries to pretend he's you, he must sit down at the machine 
and try to duplicate your signature. If he presses the pen 
hardest at different points of the signature, or if he 
accelerates the pen's motion at different points, the computer 
says he's a fake.
                                                     The system 
works well, because the average crook trying to forge your 
signature will hesitate at the hard parts. His hesitation affects 
the pen's pressure and acceleration, which tell the computer he's 
faking.
                                                     IBM 
developed the system in 1979 but isn't selling it yet. When it 
does, remember: the system works just on signatures written with 
IBM's pen.

          TRANSLATE RUSSIAN
  Soon after computers were invented, programmers tried to make 
them translate Russian into English. They chose Russian instead 
of Spanish, for three reasons:
  1. Few humans could translate Russian. Spanish translators were 
a-dime-a-dozen.
  2. Computer experts love hard problems. Russian is harder than 
Spanish.
  3. Most computers were owned by the Department of Defense, 
which is very interested in Russia.

           Early attempts
  In 1954, IBM wrote a program that translated Russian sentences 
such as:
Gasoline is prepared by chemical methods from crude oil. The 
price of crude oil is determined by the market. The quality of 
the crude oil is determined by the calorie content.
  Unfortunately, most Russian sentences are not so simple. During 
the 1960's, the end of a Russian paper on space biology was fed 
into an advanced program written by Computer Concepts, Inc. 
Here's the translation that came out:
Thus, the examination of some from fundamental RADIOBIOLOGICESKIX 
problems shows, that in this a field still very much NEREWENNYZ 
questions. This is clear, since cosmic RADIOBIOLOGI4 is very 
young RAZDELOM young science efforts of scientific different 
specialties of the different countries of the world successful 
PRODOLJENY will be expanded there are.
The computer couldn't translate the words in capital letters and 
was stumped by Russian grammar.
  The competing program, written by the Air Force, translated the 
same passage a little better:
Thus, consideration of from basic radio-biological problems shows 
that in a given region still very many unsolved questions. This 
and intelligibly, since space radiobiology is very young division 
of young science ___ space biology. However, is base to trust 
that jointly scientists of different specialties of various 
countries of world/peace radiobiological investigations in outer 
space will be successfully continued and expanded.
  In 1966, a special committee of the National Academy of 
Sciences concluded that the experience of computer translation 
was ``uniformly discouraging'' and that hiring a human translator 
was cheaper than doing the two-step process of computer 
translation followed by human editing.
  During the last 20 years, computer prices have fallen, but so 
has the availability of Americans who know Russian, so the 
computer's usefulness is still in doubt. Today, most translations 
are still done by humans, who use computers to help do the word 
processing and to search through a dictionary and thesaurus.
                                                   Famous errors
                                         If you program the 
computer to translate an English sentence into Russian, and then 
the Russian back to English, will you get back the same English 
sentence you started with?
                                         One programmer tried, 
``The spirit is willing, but the flesh is weak.'' The computer 
translated it into Russian, then back into English, and printed, 
``The booze is strong, but the meat is rotten.''
                                         Another programmer 
tried, ``Out of sight, out of mind.'' The computer printed, 
``Blind idiot.''
                                         At an engineering 
conference, a computer was translating scientific papers into 
English, when it suddenly started talking about ``water sheep''. 
Everyone was confused. Finally they figured it out: the computer 
meant hydraulic rams.

                                        Xerox's amazing translation machine
                                         In Moscow during the 
1960's, American companies were showing off their products, but 
none of the Russians were interested in Xerox's photocopiers ___ 
until some Xerox employees put on an amazing demonstration. They 
``photocopied'' some English writing, and ___ presto! ___ a 
beautiful Russian translation of it came out of the machine! The 
machine was acting as a translator! And the translation was 
flawless, even though the English text was complex!
                                         The Russians were very 
excited, and ordered hundreds of the amazing translation machine.
                                         But before shipping the 
machines, the Xerox guys confessed it was just a gag. The 
employees had sneaked the Russian version into the machine, 
before beginning the demonstration.
                                         What if Americans had 
the same sense of humor about nuclear war? ``Hello, Gorbachev? 
This is George Bush, on the hot line. We just fired some nuclear 
missiles. They're heading straight for Moscow. Ha, ha! Just 
kidding.''
