An entertaining and free e-book introducing physics – the science of motion. Now in its 26th year - and in various languages.

Motion Mountain cover Motion Mountain page 136 Motion Mountain page 91 Motion Mountain page 148 Motion Mountain page 152 Motion Mountain page 74 Motion Mountain page 153 Motion Mountain page 279

Explore the motion of wheels, birds, lightning, planets, light and empty space itself! Be fascinated by gravitational waves, by the beauty of nature and by the concepts of modern physics, from the principle of cosmic laziness – least action – to gauge symmetry – the symmetry of charges and quarks!

zippdf Free download of all 6 pdf volumes of the Motion Mountain Physics Textbook (new edition 28 of February 2016) in full colour, with embedded films and animations. This is one single zip file with ca. 380 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. If you are between the age of 16 and 106, you will enjoy it. These videos show why.

For a PRESENT to others or to yourself, buy a PAPER edition at Amazon (in black & white or in colour), at Createspace (in black & white or in colour), or at Lulu (in black & white).

New in this edition: the world distance record for throwing any object, new riddles, the pseudoscope, a film of a moving light pulse, an impressive optical illusion that makes colours disappear, and much more.

Entertaining and surprising on every page, 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.

Prizes and rewards are offered for solving a number of challenges and for helping to improve the text. You will be mentioned in the index and in the acknowledgements.
