The new, twenty-second edition of the freely downloadable physics textbook is available on http://www.motionmountain.net/traditionalchinese.html Over 1600 pages show that physics is more fun than making love. They lead through the whole of physics, from mechanics to thermodynamics, relativity, electrodynamics, quantum theory, nuclear physics, astrophysics and unification. The text promises to be fascinating and challenging on every page. The twenty-second edition now explains how it is possible to plunge a bare hand into molten lead, includes a film of an oscillating quartz inside a watch, explains how it is possible to type a letter by controlling a computer with thought alone, includes a film of a solar flare, explains the fifteen ways that colours appear in rocks plants and animals, explains the connection between cats and gauge theory, adds more ways in which the human eye invents colours that are not there, includes a list of laser types and applications, includes many images of crystals, explains how physics Plotinus and christianity come together to show that the universe and god are one and the same, adds the handcuff puzzle and several other puzzles, explains how jet pilots frighten civilians with sonic superbooms produced by fighter planes, presents the most beautiful and precise sundial available today, adds a simple photographic proof that the Earth is larger than the Moon, improves the presentation of elementary particle physics, adds a photo of a red rainbow, gives the latest discoveries on the Galileo trial, presents a fascinating mathematical aspect of Ohm's law, states the hardest open math problem that you can explain to your grandmother, adds photographs of levitation, and much more. Over 50 new illustrations and 100 new pages have been added. More than 200 women and men have helped with suggestions and material: thank you to all of them. A beautiful French translation by Benoit Clenet of a large part of the text is also available. Parts are available in Italian and Spanish. Suggestions and errata can be added at the Motion Mountain wiki. Enjoy! Christoph Schiller
