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 ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

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 ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

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

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 ...

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 ...

Robin Tucker receives funding from EPSRC and STFC. Einstein famously laboured hard to create the theory of general relativity, but it is less well known that he also helped to launch quantum mechanics ...

Professor of Mechanical and Aerospace Engineering, North Carolina State University If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall ...
