(via Minute Physics) This video is chapter 2 in my series on special relativity, and it covers spacetime diagrams, rotational and translational symmetry of both time and space, how certain ...

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?

Let the battle begin, Newton Vs Einstein. The all out battle for space-time. Both Albert Einstein and Sir Issac Newton are regarded as the forefathers of physics, but both held different theories that ...

Special relativity is beyond weird. Among its many statements are that moving clocks run slow and that moving rulers shrink. But how are we supposed to make sense of this? When you purchase through ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. When you purchase through links on our site ...

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 ...

Einstein’s special relativity, which he formulated in his “miracle year” of 1905, was a theory that revolutionised our ideas of space and time – and ultimately paved the way for some even bigger ...

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

Einstein's theory of general relativity, published in 1916, built upon his earlier work, including special relativity and the mass-energy equivalence, both published in his "Annus Mirabilis" in 1905.
