Lest I develop a reputation as a Negative Nancy, I should note that I also recently read Feynman’s [book: The Character of Physical Law], which has been sitting on my shelf for certainly more than a decade. Just a delightful book; I had forgotten how remarkable a teacher Feynman is. The whole book has the tone of Feynman’s little bit on uncertainty:

which is to say a certain extremely rehearsed casualness. The book’s casualness is in the teaching of things that are actually extremely complicated: symmetry laws (i.e., laws stating that certain quantities are unchanged when certain actions are performed), conservation laws (that the total amount of some quantity in the universe is constant), the relationship of mathematics to physics, etc. Just a delightful little gem, which ought to be read just before or just after Wilczek’s [book: Longing for the Harmonies].
