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, which he didn't much care for. These two views of ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Every satellite in the Global Positioning System carries an atomic clock, and every one of those clocks is deliberately ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...

It was the discovery that changed the universe - or rather our understanding of the universe. One hundred years ago today, Albert Einstein presented his theory of general relativity. So for the next ...
