This new volume contains four previously unpublished lectures that Feynman gave to students preparing for exams. With characteristic flair, insight and humor, Feynman discusses topics students struggle with and offers valuable tips on solving physics problems. An illuminating memoir by Matthew Sands — who originally conceived The Feynman Lectures on Physics — gives a fascinating insight into the history of Feynman’s lecture series and the books that followed. This book is rounded off by relevant exercises and answers by R. B. Leighton and R. E. Vogt, originally developed to accompany the Lectures on Physics.
