The NO BULLSHIT guide to MATH & PHYSICS and the NO BULLSHIT guide to LINEAR ALGEBRA are written by Ivan Savov. He combines 15 years of tutoring experience with a B.Eng. in electrical engineering, an M.Sc. in physics, and a Ph.D. in computer science from McGill University. Tutoring made him realize that understanding connections between concepts is much more important than memorizing facts. It’s not about how many equations you know, but about knowing how to get from one equation to another. He founded the Minireference Publishing company with a revolutionary idea for the textbook industry: making textbooks that don’t suck.
