All mass is interaction.
Richard P. FeynmanIt doesn't make a difference how beautiful your guess is. It doesn't make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment, it's wrong.

Теперь о курсе философии. Курс читал старый бородатый профессор, которого звали Робинсон. Он говорил ужасно нечетко. Я приходил на занятие, он в течение всего занятия что-то бормотал, а я не мог понять ничего. Другие студенты, похоже, понимали его чуть лучше, но они, судя по всему, вообще его не слушали. У меня оказалось с собой небольшое сверло, одна шестнадцатая дюйма в диаметре, и, чтобы убить время на этом курсе, я занимал себя тем, что зажимал пальцами сверло и сверлил в подошве своего ботинка дырки, неделя за неделей.
Наконец, однажды уже в конце курса профессор Робинсон сказал: "Бу-бу-бу-ву-бу-ву-бу-бу-ву-бу-ву...", и все заволновались! Все начали разговаривать друг с другом и обсуждать что-то, откуда я понял, что он наконец-то сказал что-то интересное, слава богу! Мне было интересно, что же именно он сказал.
Я спросил кого-то, и мне сказали: "Мы должны написать сочинение и сдать его через четыре недели".
- Сочинение о чем?
- О том, о чем он говорил весь год.
Я был убит. Единственное, что я услышал за весь семестр и что я мог вспомнить, было, когда однажды произошел подъем его речи из глубин горла на поверхность: "Бу-бу-бу-бу-ву-ву-бу-поток сознания-бу-ву-ву-бу-бу-ву", и хлюп! - все снова погрузилось в хаос.
A philosopher once said, "It is necessary for the very existence of science that the same conditions always produce the same results." Well, they don't!

What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.

There was a Princess Somebody of Denmark sitting at a table with a number of people around her, and I saw an empty chair at their table and sat down.
She turned to me and said, "Oh! You're one of the Nobel-Prize-winners. In what field did you do your work?"
"In physics," I said.
"Oh. Well, nobody knows anything about that, so I guess we can't talk about it."
"On the contrary," I answered. "It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance--gold transfers we can't talk about, because those are understood--so it's the subject that nobody knows anything about that we can all talk about!"
I don't know how they do it. There's a way of forming ice on the surface of the face, and she did it!
We are at the very beginning of time for the human race. Our responsibility is to do what we can, learn what we can, improve the solutions and pass them on. It is our responsibility to leave the men of the future a free hand. In the impetuous youth of humanity, we can make grave errors that can stunt our growth for a long time. This we will do if we say we have the answers now, so young and ignorant; if we suppress all discussion, all criticism, saying, ‘This is it, boys, man is saved!’ and thus doom man for a long time to the chains of authority, confined to the limits of our present imagination. It has been done so many times before.
Richard P. FeynmanTHE QUESTION IS, OF COURSE, IS IT GOING TO BE POSSIBLE TO AMALGAMATE EVERYTHING,
AND MERELY DISCOVER THAT THIS WORLD REPRESENTS DIFFERENT ASPECTS OF ONE THING?

CURIOSITY DEMANDS THAT WE ASK QUESTIONS,
THAT WE TRY TO PUT THINGS TOGETHER AND TRY TO UNDERSTAND THIS MULTITUDE OF ASPECTS
AS PERHAPS RESULTING FROM THE ACTION OF A RELATIVELY SMALL NUMBER OF ELEMENTAL
THINGS AND FORCES ACTING IN AN INFINITE VARIETY OF COMBINATIONS

You see, one thing is, I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of certainty about different things, but I'm not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here, and what the question might mean. I might think about it a little bit and if I can't figure it out, then I go on to something else, but I don't have to know an answer, I don't feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is so far as I can tell. It doesn't frighten me.
