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?

The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at ...

One of the most famous concepts in science was introduced in a paper with the uninspiring title, “On the Electrodynamics of Moving Bodies.” A little reading can give you the basics of relativity, ...
