这里共选了费曼谈想象力的12段话。由老贾翻译（所以标成原创）。
1
I don’t know why it is that some people find science dull and difficult, and other people find it fun and easy, but there’s one characteristic that I get a big kick from, and that is that it takes so much imagination to try to figure out what the world is really like.
我不知道为什么有些人发现科学枯燥和困难，而另一些人发现它有趣而容易；但是科学有一个特性，我从中得到非常大的乐趣，那就是，为了弄清楚世界到底是什么样子，要用到如此巨大的想象力。
2
I would like not to underestimate the value of the world-view which is the result of scientific effort. We have been led to imagine all sorts of things infinitely more marvelous than the imaginings of poets and dreamers of the past. It shows that the imagination of nature is far, far greater than the imagination of man.
我不会低估科学上的努力带来的世界观的价值。我们被引导着想象各种各样比过去的诗人和梦想家所想象的神奇无限倍的事情。事实表明，自然的想象力比人的想象力要大得多得多。
3
I find myself trying to imagine all kinds of things all the time, and I get a kick out of it, just like a runner gets a kick out of sweating. I get a kick out of thinking about these things. I can’t stop!
我发现自己总是在努力想象各种各样的事情，我从中得到很大的乐趣，就像跑步的人从出汗中得到乐趣一样。我从思考这些事情中得到很多乐趣。我停不下来！
4
It’s much more interesting for me (unless I’m working on it) to leave a mystery a mystery, rather than to make believe I know an answer to it.
对我来说，让一件神秘仍然处于神秘（除非我自己在研究它），这比让自己相信我知道它的答案要有趣得多。［老贾：如果我们“知道“了很多答案，想象力就…］
5
Knowledge is of no real value if all you can tell me is what happened yesterday. It is necessary to tell what will happen tomorrow if you do something not only necessary, but fun. Only you must be willing to stick your neck out.
如果你能够告诉我的一切都是关于昨天发生了什么，知识就没有真正的价值。你做的事要想有意思，你必须说出明天会发生什么。只不过你必须愿意冒险。
［老贾：科学之外的很多所谓理论，都只解释已经发生的事情，却不能提供预言。在费曼看来，这是“缩头乌龟”，这种理论没什么劲。］
6
It is surprising that people do not believe that there is imagination in science. It is a very interesting kind of imagination, unlike that of the artist. The great difficulty is in trying to imagine something that you have never seen, that is consistent in every detail with what has already been seen, and that is different from what has been thought of; furthermore, it must be definite and not a vague proposition. That is indeed difficult.
人们不相信科学中存在想像力，这真令人惊讶。这是一种非常有趣的想象力，不同于艺术家的想象。巨大的困难在于试图想出某种你从来没见过的东西，它又要与你见过的东西在每个细节上都一致，但是它又要与以前想过的东西不一样；而且，它还必须明确，而不是某种模糊的观点。这真地很难。
7
We have to imagine how things might look from another point of view. A point of view that perhaps we have never been able to take.
我必须想象，从另一个角度看来，事情会是什么样子。一个我们从来没有采取过的角度。
［老贾：是呀，我们大部分人永远是从固定的角度看问题。费曼特别特别强调从不同的角度看问题，而这就需要想象力。］
8
It requires careful study of the detailed experiments, and lots of thought, to lift our imagination to the point to see this.
为了将我们的想象力提高到能够看出这个（指相对论中的结果）的高度，需要对实验细节进行仔细的研究，还需要很多思考。
9
It was thought in the Middle Ages that people simply make many observations, and the observations themselves suggest the laws. But it does not work that way. It takes much more imagination than that.
在中世纪，人们认为，只要观察很多次，观察本身就会揭示出定律。但不是那样的。这需要比那个大得多的想象力。
10
I think with science, one of the things that makes it very difficult is that it takes a lot of imagination.
我认为，使科学如此困难的原因之一是，它需要非常多的想象力。
［老贾：大家为什么觉得科学困难？一般人都会说到科学需要严密的逻辑呀，复杂的数学呀，等等，但是很少人会说出：科学需要想象力。］
11
Our imagination is stretched to the utmost, not as in fiction, to imagine things which are not really there, but just to comprehend those things which are there.
我们（科学家）的想象力被发挥到最大程度，不是像小说中那样想象不存在的事情，而正是为了理解实际存在的那些事情。
最后一句了，珍惜了——
12
I gotta stop somewhere, to leave you something to imagine!
我必须在某个地方打住，好留出一些事让你们想象！
