The free physics textbook has been constantly improved for more than twenty years. The project will continue as long as possible. No profit is or has ever been made: of the sum spent so far, less than a quarter has been covered by donations.

Your donation to the tiny, charitable, non-profit association, the Motion Mountain Physikverein in Germany, that publishes the book, is welcome! Your donation will be used to improve the book, the translations and the distribution.

Thank you in advance for your support, also in the name of all readers! If you desire it, your name will be added to the list of sponsors. Your donation is tax-deducible according to German law; its proper use is controlled by the German tax authority. Contact for more information or for obtaining a receipt ("Zuwendungsbescheinigung" or "Spendenbescheinigung").

Against an addictive internet – in favour of passion.

Each of us has to choose between addiction and passion: between superficiality and dedication. Therefore there are no distractions, no lies and no half-truths on this site. Enjoy the exploration of motion in nature, and the curiosity and passion that drives it.
