On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

The objects you interact with every day are predictable – you can pick up a box, sit down in a chair without falling to the floor, or open a door without your hand passing through the knob. But if you ...

Fin-de-siècle physics: a world picture in flux -- The world of physics -- Discharges in gases and what followed -- Atomic architecture -- The slow rise of quantum theory -- Physics at low temperatures ...

Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Quantum computing has made considerable progress since theoretical ideas were first formally explored in the 1970s. It promises a dramatic leap in our ability to understand the world, improve business ...

What is World Quantum Day 2026: World Quantum Day is observed to promote the public understanding of quantum science and technology. It is celebrated anuualy on April 14. It was launched by scientists ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

Scientists have a history of trying — and failing — to link biology and quantum mechanics. The real connection between them may be in the math.
