New Millennium Edition Special Announcement

We are currently working on an exercise book for The Feynman Lectures on Physics (FLP). This book will include about 1000 exercises from the original Feynman Lectures course as taught at Caltech, covering pretty much the entire range of topics in all three volumes of FLP. Almost all of these exercises have been published before by Caltech, however the old Caltech exercise books are long out of print, and the exercises for FLP Vols. II and III, most of which originated with Feynman himself, were unfortunately never published with answers. We will be publishing them with answers, and worked-out solutions in many cases.

As a "teaser" and special challenge to Feynman physics buffs everywhere, I am posting one of the problems from the new exercise book. The first person to solve the problem correctly will win a free copy (one of my author's copies) of the FLP exercise book when it is published (which we hope will happen late this year or early next year). The problem will also be posted on The Feynman Lectures Website with the winner's solution. Please join the Feynman Lectures Forum and follow the following link to The Feynman Lectures Exercise Challenge.

CONGRATULATIONS TO RUGGERO ALTAIR, WINNER OF THE FEYNMAN LECTURES EXERCISE CHALLENGE.
