Non-Postulated Relativity by Lev Lomize is a website built around a physics book of the same name. Its focus is not an online course, but an introduction to a specialized book on “non-postulated relativity.” The site lists a large number of question-based reading prompts, such as clock synchronization, Lorentz contraction, views on the ether, the twin/clock paradox, and charge effects in moving currents, along with the corresponding page numbers in the book.
Based on the captured content, the book argues for explaining special-relativistic effects without relying directly on Einstein’s postulates, instead starting from classical physics—especially Maxwell’s equations. The author, Lev G. Lomize, was educated at the Moscow Power Engineering Institute and worked in Soviet research institutions on radio electronics, physics research, and the development of linear charged-particle accelerators. He received a Russian doctoral-equivalent degree in 1961. This engineering-physics background makes the material more focused on theoretical mechanisms than on beginner-friendly popular science or a standard university course.
The website explicitly states that free copies of the book can be obtained by contacting Andrei Lomize, and provides an email address. There is no visible information about paid courses, subscriptions, certificates, assignments, exams, or a learning community, so it is better suited as self-study reading or a research reference than as a complete educational product.
Its strengths are its highly focused topic and specific question-driven structure, making it suitable for readers who have deeper questions about why special relativity works the way it does. The author’s background is also relevant to accelerator technology and applications of electromagnetic theory. The drawbacks are that the website presentation is fairly traditional, with no clear course path, difficulty levels, practice feedback, or peer-review information. Its “non-postulated” perspective may also differ from how mainstream textbooks present the subject, so learners should compare it carefully with standard relativity and electrodynamics texts.
It is suitable for learners, teachers, or research-oriented readers who already have a high-school to university-level physics foundation and want to read specialized material on the foundations of relativity. It is not suitable for absolute beginners looking for a structured course. Access from mainland China is not discussed in the main text, so it is considered unknown.
