How much of a role did Albert Einstein's first wife play in the theory of relativity? In recent years, some historians have asserted that Einstein shared the credit for his research on the special ...

Einstein’s theories of relativity reshaped physics, but some of their implications are stranger than even he anticipated. When you follow the math to its limits, it predicts black holes, warped time, ...

Einstein’s equations look like abstract math, but when the logic is followed all the way through, the results get unsettling fast. They predict effects like time slowing down, space bending, and ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

PORTLAND, Ore. — Today is March 14, known as Pi Day for the famous mathematical constant — but it’s also Albert Einstein’s birthday. And while most people recognize Einstein for his famous equation, E ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

We talked with historian of science Michael Gordin, Princeton’s dean of the college, who has taught the popular course “The Einstein Era,” about the life and times of Princeton's most famous resident, ...
