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 of Italian, German and European heritage. He is married and has two children. Raised bilingually in Varese (Italy), he studied physics at the Universität Stuttgart (Germany) and received his PhD in physics at the Université Libre de Bruxelles (Belgium), in the department of Ilya Prigogine, supported by a grant of the Volkswagenstiftung and one of the European Union. 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 tweets at https://x.com/MotionMountainP 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, his drive to understand everything that moves, and 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. The summary of thermodynamics in one single line using the principle of smallest system entropy appeared to be new and led to a publication with Uwe Hohm.
      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 with his colleagues Arun Kenath and C. Sivaram. See his publication list on the 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, in the meantime the strand tangle model, summarizes all of physics in 1 line: crossing switches of fluctuating strands with Planck radius define the quantum of action. This fundamental principle contains relativity, gravity and gauge interactions, determines the observed elementary particles, fixes the fundamental constants to unique values, and uniquely deduces the Lagrangians of general relativity and the standard model of particle physics with massive neutrinos. 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 the data. See his strand publication list at motionmountain.net/research.html. He is cooperating with several researchers across the world.

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 all share a value: truthfulness. Truthfulness makes the world a better place. Truth in physics and in science is decided by agreement with observations. There is no knowingly false or misleading statement in the texts or the website. All statements have been carefully checked with observations. This is a science website, and science means: no lies. Therefore, "science" does not state or teach anything. Only careful observation does. Science is a method and an attitude: science is the disbelief in authorities, the belief in the ignorance of experts, the cultivation of doubt, and the habit of letting only careful observation decide what is right or wrong. If you find a statement in the texts or on this website that is or might be wrong or misleading, just write: it will be examined and improved until it is neither. If people do not answer doubts, their statements are neither true nor part of science.

A personal note. This site is for sharing knowledge about physics. If you email me politely, I will try to answer questions and to help.
