An entertaining and free e-book on physics - the science of motion.
Now in its 27th year, the text is available in English and also in French, Italian, Japanese, Vietnamese and Spanish.
Explore the motion of plants, animals, lightning, planets, charge, light and empty space itself! Be fascinated by molecular motors, black holes, the beauty of nature and of the concepts of physics, from the principle of cosmic laziness – least action – to gauge symmetry, the symmetry of charges and quarks!
New in the 2017 edition are the bouncing ball puzzle and the six matches puzzle, details about the Moon's orbit, information on blood flow, a photograph of the shadow of the Earth at the South Pole, more about flower symmetry, the maximum possible Laypunov exponent, speeds faster than light produced by ordinary light bulbs, a movie of the heart beat of a mouse embryo, the motion of trees when they wake up in the morning, the motion of a tumbling brick, and stunning images of the Sun and of the night sky.
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.

Motion Mountain is written for pupils, students, teachers and anybody curious about nature: the text is full of telling anecdotes, captivating riddles, unusual tables, astonishing photographs and beautiful films. It has been downloaded over 300 000 times.
Modern Physics: relativity and quantum physics, cosmology and particles
Entertaining and surprising on every page, the first five pdf files tell about
- Sport, raindrops and animal life: mechanics, gravity and heat,
- Moving empty space and the sky at night: relativity and the structure of the universe,
- Lightning, lasers and nerves: electricity, optics, the brain, language and truth,
- Colours and the quantum of change: quantum physics and light quanta.
- Pleasure and the stars: biophysics, nuclear physics and radioactivity.
It is a physics manual and a physics workbook. These are also physics notes. But above all, it is a guide to enjoying physics and nature.
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.
