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 ...

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 ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

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 ...

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 ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by ...

GAITHERSBURG — Albert Einstein was correct in his prediction that E=mc2, according to scientists at the Commerce Department’s National Institute of Standards and Technology (NIST) and the ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

As humans go, Albert Einstein was pretty smart. Using nothing but “thought experiments,” he figured out the fabric of the universe (special and general relativity and spacetime), the whole energy is ...
