Description: These are the lectures in physics that I gave last year and the year before to the freshman and sophomore classes at Caltech. The lectures are, of course, not verbatim-they have been edited, sometimes extensively and sometimes less so. The lectures form only part of the complete course. The whole group of 180 students gathered in a big lecture room twice a week to hear these lectures and then they broke up into small groups of 15 or 20 students in recitation sections under the guidance of a teaching assistant. In addition, there was a laboratory session once a week. We have made it easy for you to find a PDF Ebooks without any digging.
