追溯费曼技巧这个说法的来源
创建日期：2014-10-30
网上文章，以讹传讹的现象非常严重。网上流传的费曼技巧，来源不甚清晰。我经过一番努力，在网上找到了两项证据，可以证明理查德-费曼和他的老师惠勒的确赞成【通过给别人讲懂，来确保自己真的懂了】这样的见解。不过费曼本人是否正式提出过【费曼技巧】，我不能随便下结论。总之，上网时请不要轻信未经证实的信息。
证据一
……
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.”
加粗的部分翻译成中文就是：“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。”

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.
这说明：费曼的老师惠勒曾经说过【只有通过教别人，才能让自己学会】这样的话。
