<p><b>Learn about Einstein''s theory of relativity from a physics Nobel laureate and "one of the greatest minds of the twentieth century" (<i>New York Review of Books</i>) in six memorable lessons</b><br>It was Richard Feynman''s outrageous and scintillating method of teaching that earned him legendary status among students and professors of physics. From 1961 to 1963, Feynman delivered a series of lectures at the California Institute of Technology that revolutionized the teaching of physics. In <i>Six Not-So-Easy Pieces</i>, taken from these famous <i>Lectures on Physics</i>, Feynman delves into one of the most revolutionary discoveries in twentieth-century physics: Einstein''s theory of relativity. The idea that the flow of time is not a constant, that the mass of an object depends on its velocity, and that the speed of light is a constant no matter what the motion of the observer, at first seemed shocking to scientists and laymen alike. But as Feynman shows, these tricky ideas are n
