Mathematical equations aren't just useful — many are quite beautiful. And many scientists admit they are often fond of particular formulas not just for their function, but for their form, and the ...

New research has uncovered an unexpected flaw in Einstein’s theory of relativity — a gap that no one had the tools to detect ...

Special relativity inter-relates space and time in such a way that the speed of light is constant, and the theory leads to situations where two observers can disagree over time intervals and distances ...

“Thus, the general theory of relativity as a logical edifice has finally been completed”—Albert Einstein, November 25, 1915 These words were spoken by Albert Einstein one hundred years ago, concluding ...

General Theory of Relativity: brief recap of special relativity, equivalence principle, semi-Riemannian geometry, Einstein's field equations, Schwarzschild solution and implications (perihelion shift, ...

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...

Einstein had promised but later refused to publish this 1912 expository treatise, his earliest known manuscript on special relativity. No original manuscripts survive for the articles of Einstein s ...

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 ...
