Einstein's fascination with light, considered quirky at the time, would lead him down the path to a brand new theory of physics. Living half a century before Einstein, a Scotsman, James Clerk ...

Einstein has long been the go-to guy when you think “genius,” but he was once simply the adored baby of doting parents. That’s where Jennifer Berne’s new picture-book biography begins, and ...

Einstein was enthralled by light. Even as a teenager he pondered its properties. At 16, he imagined what it would be like to chase, catch up with, and ride on a light beam.

As a 16-year-old boy, Albert Einstein imagined chasing after a beam of light in the vacuum of space. He mused on that vision for years, turning it over in his mind, asking questions about the ...

Dr Sahu relied on Einstein's idea that the gravity of an object can bend and magnify rays of light. According to Einstein's general theory of relativity, an object passing in front of another ...

Albert Einstein "drops the mic" on physicists a century later 07:01. A century after Albert Einstein predicted their existence, gravitational waves have finally been detected, tiny ripples in the ...

The measurement of this effect during a solar eclipse in 1919 confirmed Einstein’s general theory of relativity: Mass warps spacetime and bends the path of light rays (SN: 10/17/15, p. 16).

Instead, it contained two small valley-like optical ridges, or potential energy minima. When the laser light beam enters one of these ridges, the distance it travels, and therefore its wavelength, ...
