One point I disagree with MumOfThree. Physics is applied math. The logic of math is essential to programming. Chemistry is applied physics. There is so much you can do with math. Strategy is easier for mathy types. Because of the visual spatial thing. And mathy types by their natures will have different interests. Which makes the world go around. I like novels/plays, read all the classics, all Proust. DH was into NF. He would read 2-3 books a week on a subject he was interested in, whether it was Dark Ages, something about WW1, whatever he was curious about that week.
