Motion Mountain, free physics textbook

How do objects and images move? Why do animals move? What is motion?

How does a rainbow form? Is levitation possible? Do time machines exist? What does 'quantum' mean? What is the maximum force found in nature? Is 'empty space' really empty? Is the universe a set? Which problems in physics are still unsolved?

This site publishes a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions.
