In 1963 Richard P. Feynman, a professor of Physics at CalTech, published Six Easy Pieces: Essentials of Physics Explained by Its Most Brilliant Teacher. Here is his opening paragraph:
This two-year course in physics is presented from the point of view that you, the reader, are going to be a physicist. This is not necessarily the case of course, but that is what every professor in every subject assumes! If you are going to be a physicist, you will have a lot to study: two hundred years of the most rapidly developing field of knowledge that there is. So much knowledge, in fact, that you might think that you cannot learn all of it in four years, and truly you cannot; you will have to go to graduate school too!
On most days, this one included, I'm happy with my B.A. in History, thank you.
