The leading Nobel Prize-winning physicist R. Feynman guides us in a simple and understandable way through Nature, in a quest for the essential characteristics of the laws that govern it: why is the law of gravity so elegant and so simple? And why is it so marvelous that Nature obeys it?

What do we think we know about physical laws, what remains to be guessed, and how will we proceed to explore these subtle and complex threads?

With a passion for research and teaching, and always striving to see established knowledge in a 'different light', Feynman, with the explosiveness of his personality, his humor, and often his disarming simplicity, gives his all in this book.
