Richard Feynman was one the most influential physicists of the 20th century; he developed the calculational tools (Feynman diagrams, etc.) which allow elementary particle physicists (like myself) to perform their research. In addition to his incredible contributions to our understanding of the sub-atomic world, Feynman was also very dedicated to physics instruction at all levels. As such, Feynman embodied my dual roles as a Professor of Physics at Penn State University, researcher and teacher, as well as my dual roles as a researcher, elementary particle physics and physics education. The Feynman Lectures was intended as a textbook for an introductory undergraduate physics course yet it contains jewels of information that can be appreciated by even the most accomplished physicist. It is an honor to make this book available to the Penn State community.
