In 1963, Richard Feynmann gave three lectures at the University of Washington. This short book (only 133 pages) is a transcript of those talks. The lectures were not really physics, but were a very informal (virtually extemporaneous) view of what the results of modern physics means to everyman. Feynman displayed his characteristic wit and charm, along with the logic of a scientist to both amuse and edify the audience. His original expectation was that it would take all three lectures to make his essential points; it turned out that he (claimed to) have covered everything he wanted to in just the first two! So he just "rambled on" for another hour, with brilliant off-the-cuff observations that might have been a little less organized than the first parts of the series, but were not a bit less entertaining. The book does an excellent job of capturing the spirit of this remarkable spokesman for physics and science.
