We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

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

Entanglement, like many quantum effects, violates some of our deepest intuitions about the world. It may also undermine Einstein's special theory of relativity Our intuition, going back forever, is ...

THIS monograph collects, in 87 pages, those deductions of the results of relativity theory that find most frequent application in physics. The applications of special relativity to kinematics, ...

A new article is a systematic review of the methods devised by scientists since the 90s to test Einstein's laws of Special Relativity, up to the highest observable energies. These types of tests are ...

The theory of relativity describes two connected scientific theories developed by the physicist Albert Einstein: special relativity and general relativity. Collectively, relativity is the idea the ...
