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 ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics.John Clarke, ...

Over the past decades, the mathematical formulation of physical theories has evolved to provide a unified framework that bridges classical mechanics, quantum mechanics and quantum information theory.

EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for ...

The foundations of quantum mechanics rest upon a rich tapestry of experimental discoveries and theoretical insights that revolutionised our understanding of nature at the microscopic scale. At its ...

Physicists are still puzzling over the true nature of dark matter and dark energy, because they have inexplicably added 10 times as much mass as normal matter has to the universe. Looking at the ...

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 ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...
