Randall Munroe is most famous for xkcd, but he’s also stepped into books, most recently with Thing Explainer, a fascinating attempt to explain complicated things with only the 1000 most common English words. He wrote about Albert Eintstein’s theories of relativity in the same style for the New Yorker with The Space Doctor’s Big Idea:
There once was a doctor with cool white hair. He was well known because he came up with some important ideas. He didn’t grow the cool hair until after he was done figuring that stuff out, but by the time everyone realized how good his ideas were, he had grown the hair, so that’s how everyone pictures him. He was so good at coming up with ideas that we use his name to mean “someone who’s good at thinking.”
As someone who’s generally aware of Einstein’s theories, but not that aware of them, this was actually really informative for me.
