An entertaining and free e-book on physics - the science of motion.

Now in its 28th year, the text is available in English and some volumes in French, Italian, Japanese, Vietnamese and Spanish.

Physics zip Physics pdf Free download of the 5 pdf volumes of the Motion Mountain Physics Textbook. The 2018 edition is a single zip file with ca. 520 MB, in full colour, with many embedded films. Every page is wonderful and captivating.

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!

The volumes of the 2018 edition tell how to rotate a ball glued into a soft mattress for ever and ever - and challenges you to be the first to film this feat; they show how to create floating images with a simple toy, explain that usual light bulbs produce speeds faster than light when switched on, tell about why it is correct to say that the sun has already set when we see it just touching the horizon in the evening, challenge you to build a high-precision ball-chain (`Netwon's cradle'), show that a formula for pi is hidden in the hydrogen spectrum, provide more fun with quantum physics and colours, tell about noise-producing plants, ask about the Spanish burton and the fool's tackle, present the measurement unit for the spiciness of chili peppers, and present many other stunning images, facts and stories about motion of things, animals, light, stars, shadows, black holes and quantum particles.

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.

Modern Physics: relativity and quantum physics, cosmology and particles

Entertaining and surprising on every page, the first five pdf files tell about

  1. Sport, raindrops and animal life: mechanics, gravity and heat,
  2. Moving empty space and the sky at night: relativity and the structure of the universe,
  3. Lightning, lasers and nerves: electricity, optics, the brain, language and truth,
  4. Colours and the quantum of change: quantum physics and light quanta.
  5. 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 additional pdf book presents, in contrast to the previous volumes, a research topic: it tells about the search for a final, unified theory of physics.
