Excellent book a little hard to read because of the exposure technique. Feynman (man Wheat etymologically in Polish) was a genius of the matter. Her diagrams are the joy of real physicists (not those who believe they are speeds greater than 300,000 km / s ..... cf. the bewildered who dared to say and write that neutrino going faster than light) ...
