快速学习法·费曼技巧(Feynman Technique)的由来

为何要考证费曼技巧的来源?

网上文章,以讹传讹的现象非常严重。博主最早在网上接触到 “费曼技巧” 的时候,印象中并没在书籍或其它地方听说过,所以需要感觉需要亲自调查确认。碰巧博主又熟练掌握了 “利用 Google 搜索引擎为网上信息寻根溯源” 的方法,调查一下 “费曼技巧” 并不困难,所以就顺手做了一番考证。

考证的结果如何?

借助 Google 搜索引擎,博主在网上找到了两项证据,可以证明费曼(Feynman)和他的老师惠勒(Wheeler)都谈到过一种关于教学与学习之间关系的经验之谈:

通过向别人清楚地解说一件事,来确认自己真的弄懂了这件事。

下面列出两项证据的引文和引用来源。

证据一:费曼谈教学经验

……Feynman was once asked by a Caltech faculty member to explain why spin 1/2 particles obey Fermi-Dirac statistics. He gauged his audience perfectly and said, “I’ll prepare a freshman lecture on it.” But a few days later he returned and said, “You know, I couldn’t do it. I couldn’t reduce it to the freshman level. That means we really don’t understand it.”

中文译文:你知道吗,我办不到。我没法把这个问题简化到大一学生的理解水平,这说明我们自己也没搞懂。

证据二:惠勒谈教学经验

……Another favorite Wheelerism is “one can only learn by teaching.” Wheeler has been the supervisor for some 50 PhDs in physics during his career, an “enormous number,” according to Jeremy Bernstein, a physicist and science writer. Wheeler’s most famous student was the late Richard P. Feynman, who received a Nobel Prize in 1965 for his work in quantum electrodynamics.

费曼的老师惠勒曾经说过类似这样的话,“只有通过教别人,才能让自己学会”。

费曼本人是否主动提出过 “费曼技巧”?

截至目前,博主尚未找到明确的证据。

后来又是谁以什么方式提出了 “费曼技巧”?

截至目前,博主认为主要的提出者和推荐者,可能是 Scott H. Young。这里是他为费曼技巧撰写的介绍资料:Learn Faster with The Feynman Technique
