“I think I can safely say that nobody understands quantum mechanics.” We talk about Richard Feynman, the physicist that said he didn't understand his own theories... and is one of the most renowned figures of theoretical physics of all time:

We cannot define anything precisely. If we attempt to, we get into that paralysis of thought that comes to philosophers, who sit opposite each other, one saying to the other, "You don't know what you are talking about!". The second one says, "What do you mean by know? What do you mean by talking? What do you mean by you?"
- The Feynman Lectures in Physics, 1964
我們無法精確定義任何事物。如果我們試圖這樣做，我們就會陷入哲學家的思想癱瘓，他們坐在對面，一個人對另一個人說：「你不知道你在說什麼！」。第二個人說：“你說的知道是什麼意思？你說的是什麼意思？你說的是什麼意思？”

今天的學生真是幸福多了，
想起當年我們必須抱著3巨册，時代真是進步。

Feynman 當年講了兩年課，在書稿完成之後，留下的話：
不為學生的應付考試、不為了進入工業或軍事應用，而是為了欣賞從物理之道探視奇妙世界之美。
"I wanted most to give you some appreciation of the wonderful world and the physicist’s way of looking at it, which, I believe, is a major part of the true culture of modern times. "
