Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

Albert Einstein's work in part led to the prediction of quantum entanglement: the idea that two particles can remain connected across vast distances of space and time. Einstein found the idea absurd ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Three letters written by Albert Einstein in 1945 are up for auction and offer an intriguing glimpse into the renowned physicist's criticisms of how scientists were interpreting physics at the quantum ...

Albert Einstein’s work so revolutionized physics that it is difficult to discuss him without slipping into hagiography. Indeed, his brilliance is so storied that his surname has become synonymous with ...

Albert Einstein and his wife, Mileva Maric (played by Johnny Flynn and Samantha Colley) look over a scientific paper in “Genius,” a TV series on the National Geographic Channel. (NGC via YouTube) ...

Albert Einstein did not normally keep a diary, but he often wrote in travel notebooks. From 1921 to 1933 his itinerary included trips to New York, Hong Kong, Singapore, Malacca, Penong, Palestine, Rio ...
