For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a picture of our reality – or even whether that is possible ...

Carlo Rovelli is a physicist at Aix–Marseille University, Marseille, France, and an associate member of the Rotman Institute of Philosophy in London, Ontario, Canada. Nature seems to have played us ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

In the pantheon of modern physics, few figures can match the quiet authority of Gerard ’t Hooft. The theoretical physicist, now a professor emeritus at Utrecht University in the Netherlands, has spent ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...

The 2024 Nobel Prize in physics has been awarded to John Hopfield and Geoffrey Hinton for their fundamental discoveries in machine learning, which paved the way for how artificial intelligence is used ...

With work on machine learning that uses artificial neural networks, John J. Hopfield and Geoffrey E. Hinton “showed a completely new way for us to use computers,” the committee said. By Derrick Bryson ...

What if, just before we reach the bottom, we find out that reductionism fails? Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in ...
