I have made available 5 years of lecture notes presented by Richard Feynman at the Hughes Research labs. The note were hand taken and retranscribed after the 2 hour lectures. The lectures I attended began on the fall of 1966 and represent over 400 hours of lectures. The lectures covered: 1 Astronomy, Astrophysics, and Cosmology 2 Electrostatics, Electrodynamics and relativity 3 Quantum Mechanics and Quantum Electrodynamics 4 Microbiology and BioPhysics 5 Mathematical methods in Physics and Engineering http://www.thehugheslectures.info/ The notes are made available for students, teachers and interested individuals who want to learn more about science, math and nature as only Feynman could present. They are not intended for any commercial use or purpose.
