This course will give a basic introduction to Einstein's special theory of relativity followed by a close reading of his classic paper on gravitation and the general theory of relativity, from 1915.

EVER since Albert Einstein struggled to present relativity in layman’s terms in 1916, physicists have sought ways to make its counterintuitions accessible. Stannard starts refreshingly with eight ...

Einstein put forth special relativity, which explains motion at near-light speeds. Although there are many consequences of Special Relativity, this complex theory consists of only two postulates, both ...

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 ...

Ever wonder what it would look like to travel at the speed of light? The folks at MIT’s education games lab have created a simple 3D simulator to teach the masses about the counterintuitive principles ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...

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?

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1916. It unifies Einstein's earlier special relativity with Sir Isaac Newton's law of universal ...

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 ...
