*The Motion Mountain Physikverein (in English: Motion Mountain Research) is a non-profit research organisation that is charitable and tax-exempt according to German law. Part of the work is done in Italy. The organisation has two aims in its statute: distributing the free physics textbook (the green web pages) and conducting research in fundamental physics (the grey web pages). Your donation, however small, is welcome – and tax-deducible. The use of the donations is controlled by the German tax authorities. Thank you in advance for any donation – also in the name of all future readers. People who read make the world a better place.
Christoph Schiller, the author of the Motion Mountain Textbook, was born in 1960 and is Italian, German and European. He is married and has two children. Raised bilingually in Varese (Italy), he studied physics at the Universität Stuttgart (Germany) and received his Ph.D. in physics at the Université Libre de Bruxelles (Belgium), in the department of Ilya Prigogine, supported by a Grant of the Volkswagenstiftung. He has also lived in Switzerland, the UK, France, Japan and the Netherlands. His Erdős number is 5, and so is his Einstein number – typical numbers for a physicist of his age. His publications and preprints are found on this site, on ResearchGate and on Google Scholar. He occasionally writes tweets at https://twitter.com/PhysicsFree and toots at https://mastodon.social/@MotionMountain.
As a physicist, Christoph Schiller is known for three reasons.
1. His freely downloadable Motion Mountain Physics Textbook makes physics simple and captivating. This book series grew from his fascination for nature, from his drive to understand everything that moves, and from his passion to write about it. It is downloaded many 10 000 times a year. He likes to summarize the book series and all of physics in 9 lines.
2. While writing, in the years leading to 2003, he formulated and published in his textbook and then in an arxiv preprint the principle of maximum force; it states that general relativity is a consequence of nature's limit force value c4/4G. The principle, discovered independently also by Gary Gibbons, is becoming a topic in an increasing number of publications. (He also won a small award for a paper explaining the topic.) See his publication list on maximum force at motionmountain.net/maximumforce.html#pp.
3. Maximum force led to his latest pastime, the strand conjecture, which is presented on the research page. The strand conjecture, or strand tangle model, summarizes all of physics in 1 line: crossing switches of fluctuating strands with Planck radius explain gravity and gauge interactions, deduce their Lagrangians, determine the observed elementary particles, and fix the fundamental constants to unique values. The tangle model builds on his discovery that the gauge groups U(1), SU(2) and SU(3) are related to the three Reidemeister moves. So far, all tests and all predictions of the strand tangle model agree with data. See his strand publication list at motionmountain.net/research.html.
As an innovator, Christoph Schiller grows high-tech businesses by transforming physics and technology into products and jobs. He also writes and talks about how experience with physics improves innovation management and risk management. Similarly, he likes to tell how experience with customers and companies helps to improve teaching and to improve research.
Pledge: Both Christoph Schiller and Motion Mountain Research fully endorse the European Code of Conduct for Research Integrity of All European Academies (ALLEA), the Rules of Good Scientific Practice of the Deutsche Forschungsgemeinschaft (DFG, the German Research Foundation), and the Responsible and Ethical Conduct of Research (RECR) of the National Science Foundation of the United States.
We share a value: truthfulness. There is no knowingly false or misleading statement in the texts or the website. All statements have been checked. Truthfulness makes the world a better place. This is a science website. Science means: no lies. If you find a statement that is wrong or could be wrong, just write. It will be improved.

A personal note. This site is for sharing knowledge about
physics. If you email me, I will try to answer questions, to help, and to
be as polite as I can. I try to behave in writing as I do in person.
Polite mails will be answered.
