Albert Einstein was well known for his thought experiments involving complex scientific ideas. Often he used real-world examples that helped non-scientists grasp his theories of relativity. He started ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary experiments—with unprecedented precision. At MIT, scientists cooled thousands of atoms to ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

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 ...

Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius's contribution to human knowledge and modern ...

Have you ever imagined the solution to a logic problem instead of calculating it? Such “thought experiments” are carried out using one’s imagination rather than doing actual research. Typically ...

EL SALTO, Mexico — Thirty minutes before totality, a large cloud dared to park in front of the sun. The sunlight split against the puffs to create a beautiful rainbow, but it was a nuisance for the ...

The most precise test yet of one of Albert Einstein’s ideas about gravity has once again shown he was right. The finding means that physicists may need experiments that are even more accurate to ...

The celebrated German physicist gave the world the Theory of Relativity revolutionizing physics after years of puzzling over it.

In the 1930's when scientists, including Albert Einstein and Erwin Schrödinger, first discovered the phenomenon of entanglement, they were perplexed. Entanglement, disturbingly, required two separated ...

Here’s what you’ll learn when you read this story: In 1927, Albert Einstein and Neils Bohr debated the nature of what’s known as complementarity—the idea that a photon’s dual wave-like and particle ...
