 <\/p>\n

this is a fun, easy to read book. i was told to read it by a friend. i read it to avoid doing the linguistics tests im supposed to do. useful procrastination ftw!<\/p>\n

 <\/p>\n

As usual, comments and quotes below<\/p>\n

——————————————<\/p>\n

 <\/p>\n

Another thing I did in high school was to invent problems and theorems. I mean, if I were doing <\/span><\/p>\n

any mathematical thing at all, I would find some practical example for which it would be useful. I <\/span><\/p>\n

invented a set of right-triangle problems. But instead of giving the lengths of two of the sides to <\/span><\/p>\n

find the third, I gave the difference of the two sides. A typical example was: There’s a flagpole, and <\/span><\/p>\n

there’s a rope that comes down from the top. When you hold the rope straight down, it’s three feet <\/span><\/p>\n

longer than the pole, and when you pull the rope out tight, it’s five feet from the base of the pole. <\/span><\/p>\n

How high is the pole? <\/span><\/p>\n

 <\/p>\n

tricky, but certainly doable for primary school children. the smart of them. im fairly certain that a lot of high school students wud not be able to solve this.<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

I tried to explain–it was my own aunt–that there was no reason not to do that, but you can’t say <\/span><\/p>\n

that to anybody who’s smart, who runs a hotel! I learned there that innovation is a very difficult <\/span><\/p>\n

thing in the real world. <\/span><\/p>\n

 <\/p>\n

truth! this is politics in a nutshell, any kind of politics: national, local, office…<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

The other guy’s afraid, so he says no. So I take the two girls in a taxi to the hotel, and discover <\/span><\/p>\n

that there’s a dance organized by the deaf and dumb, believe it or not. They all belonged to a club. <\/span><\/p>\n

It turns out many of them can feel the rhythm enough to dance to the music and applaud the band at <\/span><\/p>\n

the end of each number. <\/span><\/p>\n

 <\/p>\n

It was very, very interesting! I felt as if I was in a foreign country and couldn’t speak the <\/span><\/p>\n

language: I could speak, but nobody could hear me. Everybody was talking with signs to everybody <\/span><\/p>\n

else, and I couldn’t understand anything! I asked my girl to teach me some signs and I learned a few, <\/span><\/p>\n

like you learn a foreign language, just for fun. <\/span><\/p>\n

 <\/p>\n

Everyone was so happy and relaxed with each other, making jokes and smiling all the time; they <\/span><\/p>\n

didn’t seem to have any real difficulty of any kind communicating with each other. It was the same <\/span><\/p>\n

as with any other language, except for one thing: as they’re making signs to each other, their heads <\/span><\/p>\n

were always turning from one side to the other. I realized what that was. When someone wants to <\/span><\/p>\n

make a side remark or interrupt you, he can’t yell, “Hey, Jack!” He can only make a signal, which <\/span><\/p>\n

you won’t catch unless you’re in the habit of looking around all the time. <\/span><\/p>\n

 <\/p>\n

never thought of that, but true!<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

When it came time for me to give my talk on the subject, I started off by drawing an outline of <\/span><\/p>\n

the cat and began to name the various muscles. <\/span><\/p>\n

The other students in the class interrupt me: “We know all that!” <\/span><\/p>\n

“Oh,” I say, “you do? Then no wonder I can catch up with you so fast after you’ve had four years <\/span><\/p>\n

of biology.” They had wasted all their time memorizing stuff like that, when it could be looked up <\/span><\/p>\n

in fifteen minutes. <\/span><\/p>\n

 <\/p>\n

ive heard this complaint lots of time about biology. i rather like evolutionary biology, which surely cannot be learned in 15 mins, but i dunno abouy plant cell biology or whatever. is biology mostly just remembering stuff? surely things like genetics, pop* genetics, evolutionary theory are hard.<\/p>\n

 <\/p>\n

 <\/p>\n

At the Princeton graduate school, the physics department and the math department shared a <\/span><\/p>\n

common lounge, and every day at four o’clock we would have tea. It was a way of relaxing in the <\/span><\/p>\n

afternoon, in addition to imitating an English college. People would sit around playing Go, or <\/span><\/p>\n

discussing theorems. In those days topology was the big thing. <\/span><\/p>\n

I still remember a guy sitting on the couch, thinking very hard, and another guy standing in front <\/span><\/p>\n

of him, saying, “And therefore such-and-such is true.” <\/span><\/p>\n

 <\/p>\n

“Why is that?” the guy on the couch asks. <\/span><\/p>\n

 <\/p>\n

“It’s trivial! It’s trivial!” the standing guy says, and he rapidly reels off a series of logical steps: <\/span><\/p>\n

“First you assume thus-and-so, then we have Kerchoff’s this-and-that; then there’s Waffenstoffer’s <\/span><\/p>\n

Theorem, and we substitute this and construct that. Now you put the vector which goes around here <\/span><\/p>\n

and then thus-and-so . . .” The guy on the couch is struggling to understand all this stuff, which <\/span><\/p>\n

goes on at high speed for about fifteen minutes! <\/span><\/p>\n

 <\/p>\n

Finally the standing guy comes out the other end, and the guy on the couch says, “Yeah, yeah. <\/span><\/p>\n

It’s trivial.” <\/span><\/p>\n

 <\/p>\n

We physicists were laughing, trying to figure them out. We decided that “trivial” means <\/span><\/p>\n

“proved.” So we joked with the mathematicians: “We have a new theorem–that mathematicians can <\/span><\/p>\n

prove only trivial theorems, because every theorem that’s proved is trivial.” <\/span><\/p>\n

 <\/p>\n

i thought of that befor. it makes certain theories of tautologies rather implausible. if tautologies, or necessary truths are all trivial, and just restating things – why arent they all obvius? …<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

One thing I never did learn was contour integration. I had learned to do integrals by various <\/span><\/p>\n

methods shown in a book that my high school physics teacher Mr. Bader had given me. <\/span><\/p>\n

 <\/p>\n

One day he told me to stay after class. “Feynman,” he said, “you talk too much and you make <\/span><\/p>\n

too much noise. I know why. You’re bored. So I’m going to give you a book. You go up there in the <\/span><\/p>\n

back, in the corner, and study this book, and when you know everything that’s in this book, you can <\/span><\/p>\n

talk again.” <\/span><\/p>\n

 <\/p>\n

i wish my teachers wud hav don that to me! or that i had grown up with Khan academy!<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

In another experiment, I laid out a lot of glass microscope slides, and got the ants to walk on <\/span><\/p>\n

them, back and forth, to some sugar I put on the windowsill. Then, by replacing an old slide with a <\/span><\/p>\n

new one, or by rearranging the slides, I could demonstrate that the ants had no sense of geometry: <\/span><\/p>\n

they couldn’t figure out where something was. If they went to the sugar one way and there was a <\/span><\/p>\n

shorter way back, they would never figure out the short way. <\/span><\/p>\n

It was also pretty clear from rearranging the glass slides that the ants left some sort of trail. So <\/span><\/p>\n

then came a lot of easy experiments to find out how long it takes a trail to dry up, whether it can be <\/span><\/p>\n

easily wiped off, and so on. I also found out the trail wasn’t directional. If I’d pick up an ant on a <\/span><\/p>\n

piece of paper, turn him around and around, and then put him back onto the trail, he wouldn’t know <\/span><\/p>\n

that he was going the wrong way until he met another ant. (Later, in Brazil, I noticed some leaf-<\/span><\/p>\n

cutting ants and tried the same experiment on them. They could tell, within a few steps, whether <\/span><\/p>\n

they were going toward the food or away from it–presumably from the trail, which might be a <\/span><\/p>\n

series of smells in a pattern: A, B, space, A, B, space, and so on.) <\/span><\/p>\n

I tried at one point to make the ants go around in a circle, but I didn’t have enough patience to set <\/span><\/p>\n

it up. I could see no reason, other than lack of patience, why it couldn’t be done. <\/span><\/p>\n

 <\/p>\n

yes, that DOES happen by accident in nature.<\/p>\n

 <\/p>\n

So Frankel figured out a nice program. If we got enough of these machines in a room, we could <\/span><\/p>\n

take the cards and put them through a cycle. Everybody who does numerical calculations now <\/span><\/p>\n

knows exactly what I’m talking about, but this was kind of a new thing then–mass production with <\/span><\/p>\n

machines. We had done things like this on adding machines. Usually you go one step across, doing <\/span><\/p>\n

everything yourself. But this was different–where you go first to the adder, then to the multiplier, <\/span><\/p>\n

then to the adder, and so on. So Frankel designed this system and ordered the machines from the <\/span><\/p>\n

IBM company because we realized it was a good way of solving our problems. <\/span><\/p>\n

 <\/p>\n

We needed a man to repair the machines, to keep them going and everything. And the army was <\/span><\/p>\n

always going to send this fellow they had, but he was always delayed. Now, we always were in a <\/span><\/p>\n

hurry. Everything we did, we tried to do as quickly as possible. In this particular case, we worked <\/span><\/p>\n

out all the numerical steps that the machines were supposed to do–multiply this, and then do this, <\/span><\/p>\n

and subtract that. Then we worked out the program, but we didn’t have any machine to test it on. So <\/span><\/p>\n

we set up this room with girls in it. Each one had a Marchant: one was the multiplier, another was <\/span><\/p>\n

the adder. This one cubed–all she did was cube a number on an index card and send it to the next <\/span><\/p>\n

girl. <\/span><\/p>\n

 <\/p>\n

We went through our cycle this way until we got all the bugs out. It turned out that the speed at <\/span><\/p>\n

which we were able to do it was a hell of a lot faster than the other way where every single person <\/span><\/p>\n

did all the steps. We got speed with this system that was the predicted speed for the IBM machine. <\/span><\/p>\n

The only difference is that the IBM machines didn’t get tired and could work three shifts. But the <\/span><\/p>\n

girls got tired after a while. <\/span><\/p>\n

 <\/p>\n

Well, Mr. Frankel, who started this program, began to suffer from the computer disease that <\/span><\/p>\n

anybody who works with computers now knows about. It’s a very serious disease and it interferes <\/span><\/p>\n

completely with the work. The trouble with computers is you play with them. They are so <\/span><\/p>\n

wonderful. You have these switches–if it’s an even number you do this, if it’s an odd number you <\/span><\/p>\n

do that–and pretty soon you can do more and more elaborate things if you are clever enough, on <\/span><\/p>\n

one machine. <\/span><\/p>\n

 <\/p>\n

:D SO TRUE<\/p>\n

 <\/p>\n

All during the war, and even after, there were these perpetual rumors: “Somebody’s been trying <\/span><\/p>\n

to get into Building Omega!” You see, during the war they were doing experiments for the bomb in <\/span><\/p>\n

which they wanted to get enough material together for the chain reaction to just get started. They <\/span><\/p>\n

would drop one piece of material through another, and when it went through, the reaction would <\/span><\/p>\n

start and they’d measure how many neutrons they got. The piece would fall through so fast that <\/span><\/p>\n

nothing should build up and explode. Enough of a reaction would begin, however, so they could <\/span><\/p>\n

tell that things were really starting correctly, that the rates were right, and everything was going <\/span><\/p>\n

according to prediction–a very dangerous experiment! <\/span><\/p>\n

 <\/p>\n

O_o, very dangerus experiment indeed!<\/p>\n

 <\/p>\n

 <\/p>\n

That evening I went for a walk in town, and came upon a small crowd of people standing around <\/span><\/p>\n

a great big rectangular hole in the road–it had been dug for sewer pipes, or something–and there, <\/span><\/p>\n

sitting exactly in the hole, was a car. It was marvelous: it fitted absolutely perfectly, with its roof <\/span><\/p>\n

level with the road. The workmen hadn’t bothered to put up any signs at the end of the day, and the <\/span><\/p>\n

guy had simply driven into it. I noticed a difference: When we’d dig a hole, there’d be all kinds of <\/span><\/p>\n

detour signs and flashing lights to protect us. There, they dig the hole, and when they’re finished for <\/span><\/p>\n

the day, they just leave.<\/span><\/p>\n

 <\/p>\n

O_o<\/p>\n

 <\/p>\n

The meeting in Japan was in two parts: one was in Tokyo, and the other was in Kyoto. In the bus <\/span><\/p>\n

on the way to Kyoto I told my friend Abraham Pais about the Japanese-style hotel, and he wanted <\/span><\/p>\n

to try it. We stayed at the Hotel Miyako, which had both American-style and Japanese-style rooms, <\/span><\/p>\n

and Pais shared a Japanese-style room with me. <\/span><\/p>\n

 <\/p>\n

The next morning the young woman taking care of our room fixes the bath, which was right in <\/span><\/p>\n

our room. Sometime later she returns with a tray to deliver breakfast. I’m partly dressed. She turns <\/span><\/p>\n

to me and says, politely, “Ohayo, gozai masu,” which means, “Good morning.” <\/span><\/p>\n

Pais is just coming out of the bath, sopping wet and completely nude. She turns to him and with <\/span><\/p>\n

equal composure says, “Ohayo, gozai masu,” and puts the tray down for us. <\/span><\/p>\n

Pais looks at me and says, “God, are we uncivilized!” <\/span><\/p>\n

 <\/p>\n

We realized that in America if the maid was delivering breakfast and the guy’s standing there, <\/span><\/p>\n

stark naked, there would be little screams and a big fuss. But in Japan they were completely used to <\/span><\/p>\n

it, and we felt that they were much more advanced and civilized about those things than we were. <\/span><\/p>\n

 <\/p>\n

stupid puritanism and fear of nakedness.<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

There was a sociologist who had written a paper for us all to read–something he had written <\/span><\/p>\n

ahead of time. I started to read the damn thing, and my eyes were coming out: I couldn’t make head <\/span><\/p>\n

nor tail of it! I figured it was because I hadn’t read any of the books on that list. I had this uneasy <\/span><\/p>\n

feeling of “I’m not adequate,” until finally I said to myself, “I’m gonna stop, and read one sentence <\/span><\/p>\n

slowly, so I can figure out what the hell it means.” <\/span><\/p>\n

So I stopped–at random–and read the next sentence very carefully. I can’t remember it precisely, <\/span><\/p>\n

but it was very close to this: “The individual member of the social community often receives his <\/span><\/p>\n

information via visual, symbolic channels.” I went back and forth over it, and translated. You know <\/span><\/p>\n

what it means? “People read.” <\/span><\/p>\n

 <\/p>\n

Then I went over the next sentence, and I realized that I could translate that one also. Then it <\/span><\/p>\n

became a kind of empty business: “Sometimes people read; sometimes people listen to the radio,” <\/span><\/p>\n

and so on, but written in such a fancy way that I couldn’t understand it at first, and when I finally <\/span><\/p>\n

deciphered it, there was nothing to it. <\/span><\/p>\n

 <\/p>\n

There was only one thing that happened at that meeting that was pleasant or amusing. At this <\/span><\/p>\n

conference, every word that every guy said at the plenary session was so important that they had a <\/span><\/p>\n

stenotypist there, typing every goddamn thing. Somewhere on the second day the stenotypist came <\/span><\/p>\n

up to me and said, “What profession are you? Surely not a professor.” <\/span><\/p>\n

“I am a professor,” I said. <\/span><\/p>\n

“Of what?” <\/span><\/p>\n

“Of physics–science.” <\/span><\/p>\n

“Oh! That must be the reason,” he said. <\/span><\/p>\n

“Reason for what?” He said, “You see, I’m a stenotypist, and I type everything that is said here. Now, when the other <\/span><\/p>\n

fellas talk, I type what they say, but I don’t understand what they’re saying. But every time you get <\/span><\/p>\n

up to ask a question or to say something, I understand exactly what you mean–what the question is, <\/span><\/p>\n

and what you’re saying–so I thought you can’t be a professor!” <\/span><\/p>\n

 <\/p>\n

yes, it is mor difficult to say somthing clearly than to obscure it.<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

There was a special dinner at some point, and the head of the theology place, a very nice, very <\/span><\/p>\n

Jewish man, gave a speech. It was a good speech, and he was a very good speaker, so while it <\/span><\/p>\n

sounds crazy now, when I’m telling about it, at that time his main idea sounded completely obvious <\/span><\/p>\n

and true. He talked about the big differences in the welfare of various countries, which cause <\/span><\/p>\n

jealousy, which leads to conflict, and now that we have atomic weapons, any war and we’re <\/span><\/p>\n

doomed, so therefore the right way out is to strive for peace by making sure there are no great <\/span><\/p>\n

differences from place to place, and since we have so much in the United States, we should give up <\/span><\/p>\n

nearly everything to the other countries until we’re all even. Everybody was listening to this, and <\/span><\/p>\n

we were all full of sacrificial feeling, and all thinking we ought to do this. But I came back to my <\/span><\/p>\n

senses on the way home. <\/span><\/p>\n

 <\/p>\n

The next day one of the guys in our group said, “I think that speech last night was so good that <\/span><\/p>\n

we should all endorse it, and it should be the summary of our conference.” <\/span><\/p>\n

I started to say that the idea of distributing everything evenly is based on a theory that there’s <\/span><\/p>\n

only X amount of stuff in the world, that somehow we took it away from the poorer countries in the <\/span><\/p>\n

first place, and therefore we should give it back to them. But this theory doesn’t take into account <\/span><\/p>\n

the real reason for the differences between countries–that is, the development of new techniques <\/span><\/p>\n

for growing food, the development of machinery to grow food and to do other things, and the fact <\/span><\/p>\n

that all this machinery requires the concentration of capital. It isn’t the stuff, but the power to make <\/span><\/p>\n

the stuff, that is important. But I realize now that these people were not in science; they didn’t <\/span><\/p>\n

understand it. They didn’t understand technology; they didn’t understand their time. <\/span><\/p>\n

 <\/p>\n

sounds like sorryaboutcolonialism (see http:\/\/www.everythingisaremix.info\/everything-is-a-remix-part-2-transcript\/<\/a>).<\/p>\n

 <\/p>\n

these inequalities ar ther becus of ppl ar unequal to begin with. even if we redistributed wealth, it wudnt take long b4 whites and asians were superior again.<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

Once I was asked to serve on a committee which was to evaluate various weapons for the army, <\/span><\/p>\n

and I wrote a letter back which explained that I was only a theoretical physicist, and I didn’t know <\/span><\/p>\n

anything about weapons for the army. <\/span><\/p>\n

 <\/p>\n

The army responded that they had found in their experience that theoretical physicists were very <\/span><\/p>\n

useful to them in making decisions, so would I please reconsider? <\/span><\/p>\n

I wrote back again and said I didn’t really know anything, and doubted I could help them. <\/span><\/p>\n

Finally I got a letter from the Secretary of the Army, which proposed a compromise: I would <\/span><\/p>\n

come to the first meeting, where I could listen and see whether I could make a contribution or not. <\/span><\/p>\n

Then I could decide whether I should continue. <\/span><\/p>\n

I said I would, of course. What else could I do? <\/span><\/p>\n

I went down to Washington and the first thing that I went to was a cocktail party to meet <\/span><\/p>\n

everybody. There were generals and other important characters from the army, and everybody <\/span><\/p>\n

talked. It was pleasant enough. <\/span><\/p>\n

 <\/p>\n

One guy in a uniform came to me and told me that the army was glad that physicists were <\/span><\/p>\n

advising the military because it had a lot of problems. One of the problems was that tanks use up <\/span><\/p>\n

their fuel very quickly and thus can’t go very far. So the question was how to refuel them as they’re <\/span><\/p>\n

going along. Now this guy had the idea that, since the physicists can get energy out of uranium, <\/span><\/p>\n

could I work out a way in which we could use silicon dioxide–sand, dirt–as a fuel? If that were <\/span><\/p>\n

possible, then all this tank would have to do would be to have a little scoop underneath, and as it <\/span><\/p>\n

goes along, it would pick up the dirt and use it for fuel! He thought that was a great idea, and that <\/span><\/p>\n

all I had to do was to work out the details. That was the kind of problem I thought we would be <\/span><\/p>\n

talking about in the meeting the next day. <\/span><\/p>\n

 <\/p>\n

i wonder… ar they still so depressingly dumb?<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

This question of trying to figure out whether a book is good or bad by looking at it carefully or <\/span><\/p>\n

by taking the reports of a lot of people who looked at it carelessly is like this famous old problem: <\/span><\/p>\n

Nobody was permitted to see the Emperor of China, and the question was, What is the length of the <\/span><\/p>\n

Emperor of China’s nose? To find out, you go all over the country asking people what they think <\/span><\/p>\n

the length of the Emperor of China’s nose is, and you average it. And that would be very “accurate” <\/span><\/p>\n

because you averaged so many people. But it’s no way to find anything out; when you have a very <\/span><\/p>\n

wide range of people who contribute without looking carefully at it, you don’t improve your <\/span><\/p>\n

knowledge of the situation by averaging. <\/span><\/p>\n

 <\/p>\n

F seems to be wrong, but he might hav a point about the conditions under which wisdom of the crowds averaging works. https:\/\/en.wikipedia.org\/wiki\/Wisdom_of_the_crowd<\/a><\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

I thought: “Now where is the ego located? I know everybody thinks the seat of thinking is in the <\/span><\/p>\n

brain, but how do they know that?” I knew already from reading things that it wasn’t so obvious to <\/span><\/p>\n

people before a lot of psychological studies were made. The Greeks thought the seat of thinking <\/span><\/p>\n

was in the liver, for instance. I wondered, “Is it possible that where the ego is located is learned by <\/span><\/p>\n

children looking at people putting their hand to their head when they say, ‘Let me think’? Therefore <\/span><\/p>\n

the idea that the ego is located up there, behind the eyes, might be conventional!” I figured that if I <\/span><\/p>\n

could move my ego an inch to one side, I could move it further. This was the beginning of my <\/span><\/p>\n

hallucinations. <\/span><\/p>\n

Feynmann didnt do his research properly.<\/p>\n

https:\/\/en.wikipedia.org\/wiki\/History_of_neuroscience#Early_views<\/a><\/p>\n

<\/a>\u201dDuring the second half of the first millennium BC, the Ancient Greeks<\/a> developed differing views on the function of the brain. It is said that it was the Pythagorean<\/a> Alcmaeon of Croton<\/a> (6th and 5th centuries BC) who first considered the brain to be the place where the mind was located. In the 4th century BC Hippocrates<\/a>, believed the brain to be the seat of intelligence (based, among others before him, on Alcmaeon’s work). During the 4th century BC Aristotle<\/a> thought that, while the heart was the seat of intelligence<\/a>, the brain was a cooling mechanism for the blood. He reasoned that humans are more rational than the beasts because, among other reasons, they have a larger brain to cool their hot-bloodedness.[2]<\/a>\u201d<\/p>\n

 <\/p>\n

–<\/p>\n

 <\/p>\n

Other kinds of errors are more characteristic of poor science. When I was at Cornell, I often <\/span><\/p>\n

talked to the people in the psychology department. One of the students told me she wanted to do an <\/span><\/p>\n

experiment that went something like this–it had been found by others that under certain <\/span><\/p>\n

circumstances, X, rats did something, A. She was curious as to whether, if she changed the <\/span><\/p>\n

circumstances to Y, they would still do A. So her proposal was to do the experiment under <\/span><\/p>\n

circumstances Y and see if they still did A. <\/span><\/p>\n

 <\/p>\n

I explained to her that it was necessary first to repeat in her laboratory the experiment of the <\/span><\/p>\n

other person–to do it under condition X to see if she could also get result A, and then change to Y <\/span><\/p>\n

and see if A changed. Then she would know that the real difference was the thing she thought she <\/span><\/p>\n

had under control. <\/span><\/p>\n

 <\/p>\n

She was very delighted with this new idea, and went to her professor. And his reply was, no, you <\/span><\/p>\n

cannot do that, because the experiment has already been done and you would be wasting time. This <\/span><\/p>\n
