Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

"The whole thing was basically an experiment," Richard Feynman said late in his career, looking back on the origins of his lectures. The experiment turned out to be hugely successful, spawning publications that have remained definitive and introductory to physics for decades. Ranging from the basic principles of Newtonian physics through such formidable theories as general relativity and quantum mechanics, Feynman's lectures stand as a monument of clear exposition and deep insight.

Timeless and collectible, the lectures are essential reading, not just for students of physics but for anyone seeking an introduction to the field from the inimitable Feynman.

Learn how to think like a physicist from a Nobel laureate and "one of the greatest minds of the twentieth century" (New York Review of Books) with these six classic and beloved lessons 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 around the world. Six Easy Pieces, taken from these famous Lectures on Physics, represent the most accessible material from the series. In these classic lessons, Feynman introduces the general reader to the following topics: atoms, basic physics, energy, gravitation, quantum mechanics, and the relationship of physics to other topics. With his dazzling and inimitable wit, Feynman presents each discussion with a minimum of jargon. Filled with wonderful examples and clever illustrations, Six Easy Pieces is the ideal introduction to the fundamentals of physics by one of the most admired and accessible physicists of modern times. "If one book was all that could be passed on to the next generation of scientists it would undoubtedly have to be Six Easy Pieces."- John Gribbin, New Scientist

Learn about Einstein's theory of relativity from a physics Nobel laureate and "one of the greatest minds of the twentieth century" (New York Review of Books) in six memorable lessons 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 Six Not-So-Easy Pieces, taken from these famous Lectures on Physics, 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 not merely dry principles of physics, but things of beauty and elegance. No one - not even Einstein himself - explained these difficult, anti-intuitive concepts more clearly, or with more verve and gusto, than Feynman. Filled with wonderful examples and clever illustrations, Six Not-So-Easy Pieces is the ideal introduction to the fundamentals of physics by one of the most admired and accessible physicists of all time. "There is no better explanation for the scientifically literate layman." -Washington Post Book World

Combined into one volume for the first time, the updated and clarified "Exercises for the Feynman Lectures on Physics" provides comprehensive, hands-on practice in all the most important areas of physics--from Newtonian mechanics through the theory of relativity and quantum mechanics.
A perfect complement to "The Feynman Lectures on Physics," these exercises have all been assigned in Caltech's mandatory two-year introductory physics course, either when Richard Feynman was teaching it, or during the nearly two decades that followed when "The Feynman Lectures on Physics" was used as the textbook. With this modern, easy-to-use volume, students of physics will have a chance to apply what they have learned in the "Lectures" and to enhance and reinforce the concepts taught by the inimitable Richard Feynman.

Timeless and collectible, the lectures are essential reading, not just for students of physics but for anyone seeking an introduction to the field from the inimitable Feynman.

It's win-win for the whole family: Kids love puzzles--and parents love their kids to love puzzles. Now from Puzzability--the premier puzzle-writing company whose mind-benders have appeared regularly in "The New York Times" and "Disney Adventures," and repeatedly in "The New Yorker" and "Martha Stewart Kids"--comes a rich, original, and entertaining category-killer of a book with over 250 puzzles on every imaginable theme and subject.
Fully illustrated in color, here is a bonanza of mazes, word games, visual and logic puzzles, and more. With a full range of difficulty, but all totally solvable, the puzzles are not meant to be tests. In fact they're engaging and humorous, as fun to work on as they are satisfying to solve. In Gray Matter, readers first solve a short crossword, then use the letters in the puzzle to crack a riddle. Hot Lines involves matching kids to their clothing--based on tan lines. Flea Circuit is an unusual maze that you find your way out of by jumping around the page like a flea. A scavenger hunt runs through the book--solve every puzzle to amass the clues and earn the bound-in certificate of achievement. (Yes, the honor system applies.)

History finally comes out of the water-closet in
this exploration of how people's need to relieve themselves shaped human
development from ancient times to the present. Throughout time, the most
successful civilizations were the ones who realized that "everyone" poops, and they
had better figure out how to get rid of it From the world's first flushing toilet
invented by ancient Minoan plumbers to castle moats in the middle ages that
used more than just water to repel enemies, Sarah Albee traces human
civilization using one revolting yet fascinating theme.
