Before selecting a physics book to read and report on, I had never heard of Richard Feynman.  While researching different possibilities, however, I was intrigued that Physicist Richard Feynman was described as an "icon for late twentieth-century physics (Davies, Paul, introduction)" and whose achievements were comparable to those of Isaac Newton and Albert Einstein.  I wanted to find out more about this man.<br> Six Easy Pieces is compiled from a series of lectures that Feynman taught in an introductory physics course at Caltech. He was accustomed to teaching upper level physics courses.  In 1961, in an effort to reenergize the undergraduate physics department Feynman was asked to teach a two year series of an introductory physics course to freshman and sophomore. As the title suggests, Feynman selected the six most basic lectures (Atoms in Motion, Basic Physics, The Relation of Physics to Other Sciences, Conservation of Energy, The Theory of Gravity, and Quantum Behavior) to be included in the book.<br> Feynman, possessing an incredible amount of knowledge, and accustomed to teaching graduate students, had a difficult time explaining the concepts of physics in terms that freshman and sophomores could understand.  Said he, "I thought to address [the lectures] to the most intelligent in the class and to make sure, if possible, that even the most intelligent student was unable to completely encompass everything." As a result, many students dreaded the class and stopped coming.  I had similar feelings while reading the book.  The concepts were incredibly fascinating, and were sometimes explained in a way that made it clear.  Other times, however, the concepts (which I'm sure are still fascinating) were explained in such a way that I believe only an upper level graduate student could understand them.  This turned me off a bit as it sometimes felt like I was just reading words on a page with no prayer of grouping them into cohesive and understandable thoughts.  Faculty members and graduate students later replaced the empty seats of the lecture hall.  Similarly, I think that this book would be most embraced by trained physicists.<br> Overall, I enjoyed Six Easy Pieces.  Despite being difficult to understand, it stretched my knowledge of several concepts and helped me to see the world in a way that I had not previously seen it before.  I give it 3 and a half out of 5 stars.
