Now, what should we teach first? Should we teach the correct but unfamiliar law with its strange and difficult conceptual ideas, for example the theory of relativity, four-dimensional space-time, and so on? Or should we first teach the simple “constant-mass” law, which is only approximate, but does not involve such difficult ideas? The first is more exciting, more wonderful, and more fun, but the second is easier to get at first, and is a first step to a real understanding of the first idea. This point arises again and again in teaching physics. At different times we shall have to resolve it in different ways, but at each stage it is worth learning what is now known, how accurate it is, how it fits into everything else, and how it may be changed when we learn more.

实在是太有意思了！ Feynman告诉我们：如果你感觉这件事是这样的，那就假设它就是这样的，然后做实验来验证； 这才是发现真理的方法，哲学毫无用处，“逻辑必然性”只会阻碍人的思考。 Forget about philosophy and embrace intuitions and experiments! You'll understand e...
