Feynman was a brilliant scientist and mathematician, and a wonderful communicator.
At his best, Feynman was able to describe complex science in terms of simple concepts and principles. The film is full of his exciting and engaging explanations, sometimes even using graphic techniques, as in his diagrams of subatomic scattering in quantum field theory. These systemically elaborated diagrams were named after Feynman.
In the film, you can watch the Feynman family camper-van decorated with Feynman diagrams.
Feynman was a prolific author, and there are a number of his texts, in PDF form, here
