Best Explainers on Different Subjects

There are many recommended reading threads on lesswrong. Some examples include: Math, Textbooks and Rationality.

I am looking to compile another such thread, this time aimed at “exceptional explainers” and their works. For example, I find Richard Feynman’s QED: The Strange Theory of Light and Matter to be one such book.

Please list out other authors and books which you think are wonderfully written, in such a way that maximizes communication and explanation to laypeople in the given field. For example:

Physics: Richard Feynman—QED: The Strange Theory of Light and Matter.

Thank you,

Jeremy
