Motion Mountain cover This is an entertaining and free e-book in six pdf files introducing physics – the science of motion. Explore the motion of wheels, birds, lightning, planets, light and empty space itself! Be fascinated by the beauty of nature and the concepts of modern physics, from the principle of cosmic laziness – least action – to gauge symmetry!

The text guarantees to be entertaining, surprising and challenging on every page. If you are between the age of 16 and 106, you will enjoy it. These videos show why.

zippdfClick here for the free download of all 6 pdf volumes of the Motion Mountain Physics Textbook (edition 25.6 of November 2013) in full colour, with embedded films and animations. This is one single zip file with 240 MB. Every page is wonderful and captivating.

Find out what fireworks, mobile phones and butterflies have in common, how muscles work, how colours appear, how levitation is possible, why we can see the stars, and which problems in physics are still unsolved.

New in this edition: a video of what happens inside a magnet and animations proving the spin-statistics theorem – watch them here; taking X-ray images of whole cars; a puzzle on how to hang a picture on the wall; the first gears found in nature; what sneezing has to do with molecular motors; how to use electrodynamics to find out the number you are thinking of; how to measure the speed of the grim reaper; and how to use topology and a pencil to entertain a party.

With hundreds of colour pictures, embedded films, stories and puzzles, the pdf files tell about sport, raindrops and animal life (mechanics, gravity and heat), about moving empty space and the sky at night (relativity and the structure of the universe), about lightning, lasers and nerves (electricity, optics, the brain, language and truth), and about colours, pleasure and the stars (quantum physics, nuclear physics and radioactivity). The sixth and last volume presents, in contrast to the previous ones, a research topic; it tells about the search for a final, unified theory of physics.

Tablet reading is possible. iPad and iPhone users can read read the pdf files in the browser, or with the free Adobe Reader or with PDF Reader Pro Edition. On the Samsung Galaxy and the ASUS Transformer running Android 4, the pdf files can be read normally with any pdf viewer app. There is also an epub edition available.

Translations: the three volumes on mechanics, heat, relativity and electricity are available in French, due to the fantastic effort of Benoît Clénet. Special relativity is available in Spanish, in German and in Italian. The section on mechanics is partially available in Russian.

Prizes and rewards are offered for solving a number of challenges and for helping to improve the text. For doing this you will be mentioned in the index and in the acknowledgments.
