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 ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...

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 ...

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

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 ...
