As about a year ago, here is a new version of the free physics textbook provided for free by our charitable non-profit organisation. The new, twenty-second edition of the freely downloadable physics textbook is available on www . motionmountain . net 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

I switched the server to deliver zipped pdf files instead of pure pdf files, so that the problem should not appear any more. Enjoy! Christoph

Just search for file names with motionmounatin in them. Regards Christoph

Just to switch your spam filters off: this is free and non-commercial. The new, twenty-first edition of the freely downloadable physics textbook is available on www . motionmountain . net Almost 1500 pages lead through the whole of physics, from mechanics to relativity, electrodynamics, thermodynamics, quantum theory, nuclear physics, astrophysics and unification. Over hundred new figures and tables, and numerous explanations have been added, with many examples from animals, plants and machines. The twenty-first edition now explains why the speed of light is too slow to speculate with success on the stock exchange, adds the second-level bear fur colour puzzle and the young mother puzzle, presents the nearest place with a pressure permanently lower than that of the atmosphere, adds the puzzle about the horse and the snail on a rubber, tells more about metamaterials, adds some simple chemical puzzles, presents what incredible things on atomic layers one can discover using a pencil and sticky tape, tells more on biological rhythms and clocks, explains how to observe the rotation of the Earth in any classroom after two seconds of observation, shows an electric effect observed on many playgrounds, shows the beauty of bursting soap bubbles and bouncing tennis balls, explains how it is possible to observe the motion of single, isolated electrons, gives more details on the shape of the proton, and tells how to build the simplest possible radio control system. The first 360 pages are available also in French, due to the great work of Benoit Clenet, and can be downloaded from the bienvenue page. A wiki open to everybody now keeps track of misprints and suggestions. Enjoy the reading! Christoph Schiller

I'll try to make it sound less like spam net time. Thank you all for your understanding. Christoph Schiller

A pity that this time the link was taken out. In the past, the forum had a different policy. (Just search for motionmountain and look up when I joined the forum.) I post a message about my motion mountain physics text every 6 months or so; it is a pity that some people cannot imagine that this is not spam. Besides, there is more information about me on the motionmountain website. Christoph Schiller

The new, nineteenth edition of the free Motion Mountain physics text can now be downloaded at http://www.motionmountain.net (put back in again by decision of moderator) Over 1000 pages lead through the whole of physics, from mechanics to relativity, electrodynamics, thermodynamics, quantum theory, nuclear physics and unification. The nineteenth edition gives details on radiometric dating techniques, explains how to destroy airplanes with thermometers, shows how to use the same idea to measure the speed of bullets and that of light, presents a classical system that obeys the Schroedinger equation, introduces Tesla coils, shows that space-time has different properties in certain patent offices, tells how to see effects from atoms using only a lamp and a piece of metal, gives more details on clouds and jets of astronomic size, shows how to perform a precision Michelson-Morley experiment, gives the latest results on the Pioneer anomaly, introduces fusion reactors, demonstrates the chromatic lens errors of the eye, and presents the simplest unsolved problem about the trefoil knot. The text also provides improved writing, more figures, more curiosities, many additional solutions to the challenges, and, thanks to the help of Martin Elsaesser, the first embedded animation. Many thanks also to all those readers who have suggested improvements and material for the text. An errata page that allows direct feedback via the website is now available. Enjoy.

I wrote this up for all those who are interested in physics. It is just for fun, and there is no commercial interest in it. The latest edition of the free Motion Mountain physics text can be downloaded at http://www.motionmountain.net In total, over 1200 pages lead through the whole of physics, from classical mechanics to relativity, electrodynamics, thermodynamics, quantum theory, nuclear physics and unification. The eighteenth edition adds more about the echolocation capabilities of bats and humans, describes the puzzle of Einstein's last birthday present, gives more details on rainbows, introduces the pearl necklace length contraction paradox and presents the Einstein-de Haas effect and the Barnett effect. The text now provides the classification of rocks, shows how to use the high voltage from a computer monitor to make things levitate, introduces magnetoreception and the sensing of electrical fields, explains the Richter scale for earthquakes, gives an introduction into the behaviour of solids, liquids and gases at lowes temperatures and presents the potentially toughest challenge of physics. Numerous figures, photographs and puzzles have been added. The section on special relativity and several other chapters have been improved thoroughly. Over 60 pages of new material have been added, often triggered by remarks and suggestions of readers. A warm thank you to all of them. If you find a boring page, do complain - I'll change it. Enjoy.
