Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

Hunting spacetime fluctuations could unite Einstein and quantum physics By Michael Irving December 05, 2023 An artistic impression of an experiment investigating whether spacetime follows classical or ...

A pair of scientists from the UK recently published a pre-print research paper discussing the theory of a universe with no beginning. Imagine it: our universe has always existed. The Big Bang either ...

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 ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

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

Out with the old: Many undergraduate physics curricula need revamping. (Courtesy: iStock/Pobytov) Physics education has a high inertia towards change. While high-school students in today’s biology ...

In this video, we explore five key areas of physics: **Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal ...
