In his discussion of accelerated motion on page 60 of "The Meaning of Relativity," Albert Einstein made an approximation that allowed him to develop the theory of relativity further. Einstein ...

Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: the unification of general relativity and quantum mechanics. For over a ...

This project reconstructs quantum theory’s conventional set theoretic metrical formalism, grounded in object elements, as a category theoretic topological formalism grounded in object relations. The ...

Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...

Gravity might be able to quantum-entangle particles even if the gravitational field itself is classical. That is the conclusion of a new study by Joseph Aziz and Richard Howl at Royal Holloway ...

It is a matter for celebration when two illustrious theoreticians such as Kip Thorne and Roger Blandford provide an in-depth description of the fundamentals of classical physics. Modern Classical ...
