The philosophy of inquiry into physics

Highly interesting, and unique in style.

MOTION MOUNTAIN
The Free Physics Textbook


This site provides a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written for the curious: it is entertaining, surprising and challenging on every page. With little mathematics, starting from observations of everyday life, the text explores the most fascinating parts of mechanics, thermodynamics, special and general relativity, electrodynamics, quantum theory and modern attempts at unification. The essence of these fields is summarized in the most simple terms. For example, the text presents modern physics as consequence of the notions of minimum entropy, maximum speed, maximum force, minimum change of charge and minimum action.


Quote of the month (from the text):
"Imagine a rubber band that is attached to a horse at one end and attached to a wall at the other end. The rubber is infinitely stretchable. On the rubber, near the wall, there is a snail. Both the snail and the horse start moving with typical speeds. Can the snail reach the horse?"


For each field of physics, the text presents the latest research results, the best animations, the best images, the most interesting physical puzzles and the most telling physical curiosities. It includes more than 550 animations and illustrations, more than 100 tables and more than 1600 challenges and puzzles.

Written in English, over 1500 pages are provided for students, teachers, and for anybody who is curious about the precise description of nature. To satisfy even the most extreme curiosity, the text ends by exploring the limits of time and space, and the wonders that can be discovered there.

Motion Mountain is downloaded over 30 000 times a year. It aims to be among the best introductory physics texts available. Do you have an idea for improving it? Add it to the suggestion wiki! For a valuable suggestion, I will add you to the sponsor and acknowledgment list, or send you a reward.
