    RECOMENDED BOOKS:

    great introductory texts:

    “Relativity Visualized” by Lewis Carroll Epstein https://www.amazon.com/Rela......

    There’s also this PDF that takes Epstein’s diagrams into more detail: http://www.relativity.li/up......

    “Relativity Simply Explained” by Martin Gardener https://www.amazon.com/Rela......

    great intro to the math of general relativity:

    “A Most Incomprehensible Thing: Notes Towards a Very Gentle Introduction to the Mathematics of Relativity” by Peter Collier https://www.amazon.com/Most......

    Requires some background in relevant math topics (see above) but very very good:

    In Mind Field, host Michael Stevens brings his passion for science to his most ambitious subject yet: something we still know very little about, human behavior.

    Using real subjects (including guest stars and Michael himself) Mind Field reveals some of the most mind-blowing, significant, and least-understood aspects of the human psyche.

    Through expert interviews, rare footage from historical experiments, and brand-new, ground-breaking demonstrations of human nature at work, Mind Field explores the surprising things we know (and don’t know) about why people are the way they are.
