首先感谢@吴笛，很早以前就知道这个FEYNMAN TECHNIQUE,而且总觉的自己已经明白了，感觉自己有在潜意识中当中会去应用，可是如果没有@吴笛的提醒，我想我不会再去对这个东西进行重新的，更深一步的思考。
FEYNMAN TECHNIQUE到底是什么东西呢？其实应该本质上来说：是以大妈级的语言来解释一些专业上的问题，用我们日常随处可见的现象来解释专业上的问题。总之：他是用极其具象的东西来回答高度抽象的东西。
现在我想追溯一下这个FEYNMAN TECHNIQUE是怎么来的，FEYNMAN在他的《the pleasure of finding things out》有做如下描述：
my father used to sit me on his lap and read to me from the Encyclopaedia Britannica, and we would read, say, about dinosaurs and maybe it would be talking about the brontosaurus or something, or the tyrannosaurus rex, and it would say something like, “This thing is twenty-five feet high and the head is six feet across,” you see, and so he’d stop all this and say, “Let’s see what that means. That would mean that if he stood in our front yard he would be high enough to put his head through the window but not quite because the head is a little bit too wide and it would break the window as it came by.” Everything we’d read would be translated as best we could into some reality and so I learned to do that–everything that I read I try to figure out what it really means, what it’s really saying by translating and so (LAUGHS)
接下来我想解释一下这个FEYNMAN TECHNIQUE为什么这么有用呢？
1：他符合大脑的认知规律，大家应该很清楚，我们大脑认识这个世界，是一个盖房子的过程，我们认识一个概念，肯定是有一个基石存在的，就像我们怕楼梯，我们之所以比如说在第七个楼梯，是因为我们借助了第六个楼梯。以此类推。
2：FEYNMAN TECHNIQUE 另外一直挑战我们的认知，你有没有办法用更简单的东西解释呢？你有没有办法让文盲都能理解呢？为什么这样有好处呢？因为这样的话，你的知识他不是抽象的，他是具体的，你可以在你周遭的世界中能看到知识。同时因为这样，你就有办法触类旁通，举一反三。比如就像FEYNMAN在他的《the pleasure of finding things out》有描写：
I listened to a conversation between two
girls, and one was explaining that if you want to make a straight line, you
see, you go over a certain number to the right for each row you go up, that is,
if you go over each time the same amount when you go up a row, you make a
straight line. A deep principle of analytic geometry! It went on. I was rather
amazed. I didn’t realize the female mind was capable of understanding analytic
geometry.
She went on and said, “Suppose you have
another line coming in from the other side and you want to figure out where
they are going to intersect.” Suppose on one line you go over two to the right
for every one you go up, and the other line goes over three to the right for
every one that it goes up, and they start twenty steps apart, etc.–I was
flabbergasted. She figured out where the intersection was! It turned out that
one girl was explaining to the other how to knit argyle socks.
I, therefore, did learn a lesson: The
female mind is capable of understanding analytic geometry. Those people who
have for years been insisting (in the face of all obvious evidence to the
contrary) that the male and female are equal and capable of rational thought
may have something. The difficulty may just be that we have never yet
discovered a way to communicate with the female mind. If it is done in the
right way, you may be able to get something out of it.
3: 我们的思维还有一个特点：自发性，发散性。无法自律性。意思是说其实我们的大脑就像一匹野马，而我们需要驾驭他，而FEYNMAN TECHNIQUE提供了这个东西。
A: 提供了目标，我们要做想清楚什么问题，我们要解决什么问题。
B: 提供了标准，是否我们可以以我们自己的语言来解释。
C: 有了目标和标准，我们就有了可以参照的地方，我们就可以知道我们进度到哪里了。我们还需要怎么做。
总而言之：我觉的FEYNMAN TECHNIQUE 就像孙悟空头上的紧箍咒，而因为我们的大脑的猴性，我们需要这个东西。
另外我觉的实施FEYNMAN TECHNIQUE的最重要的一点是：一定要写下来。而不是在大脑中想，因为大家都清楚，其实我们的大脑的短期记忆容量是非常有限的，所以为了最优化使用大脑，我们需要写下来，让大脑腾出空间，做重要的事情。
PS:我们怎样才算是真正理解一个东西？
如果我们理解了一个东西，我们脑袋瓜中应该形成的是一个形象，非常具体的形象。或者说如果我们真正理解了一个东西，我们似乎能感知到这个东西，似乎他们是有生命的。如果我们真正理解了一个东西，我们可以翻来覆去，360度无死角，无残留。如果我们真正理解了一个东西，我们会发现自己的逻辑非常清晰，条理非常清楚，内心非常有数。
所以理解一个东西的过程就是大脑从混沌走向有序的过程。混沌是因为你没有意识到你大脑已经知道的信息。就像大自然藏有所有的奥秘，只是你还没有认识到，领会到一样。混沌是因为我们大脑认知的习惯是：认识一个模糊的整体。就像我们眼睛看到的东西基本来源于我们的记忆，构建的主体是我们的记忆。
我们怎样才能让大脑从混沌走向有序呢？
首先明确的一点是：THERE IS NO END. 永无止境。没有最好，只有更好。
因为大脑的认知习惯，我们如果要大脑摆脱这种模糊的混沌状态，我们只能从关注细节开始。点到面。大脑认知的习惯是：面。而我们需要往这个面里面填充点，这样这个面才能撑得开。（未完待续）
其实没有那么多悬的东西，为什么费曼的这个方法有效呢，我想主要的原因它是让我们的大脑由被动接受变成主动的创造的状态。
我真的不知道一个人真的只有通过看书，看别人的言论，观点等就能悟道，如果是的话，我很好奇他是怎么做到的。
我只是觉得不管怎样，我们需要放下书本，去实践，去体验，去观察，去琢磨，去尝试，去创造，去设计，去stay hungry, stay foolish。
