Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A ...

Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...

Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...

Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

At an event to mark the 100th anniversary of quantum mechanics last month, lauded specialists in quantum physics argued politely — but firmly — about the issue. “There is no quantum world,” said ...

Reinhard Dörner explains: "In the quantum world, atomic nuclei are not tiny spheres that remain fixed in place. They are more like vibrating clouds. Even if we cool a molecule down to absolute zero, ...
