Over 300 exercises, many new to this edition, give students the confidence to work with general relativity and the necessary mathematics, whilst the informal writing style makes the subject matter ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a ...

Their results provide one of the most stringent tests yet of Albert Einstein’s general theory of relativity. “General relativity has been very well tested at the scale of solar systems, but we also ...
