It is as if one person said, ‘It is bitter cold in Chicago’; and another answered, ‘That is a fallacy, it is very hot in ...

The seeds of quantum theory were sown by Albert Einstein and others as early as 1905. But the theory came together properly 100 years ago in 1925 – and has exerted its influence ever since, as this ...

In commemoration of the 100th anniversary of modern quantum mechanics, a survey asked physicists for their takes on some hot questions in quantum theory. reading time 4 minutes In July 1925—exactly a ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

After escaping the Nazis by minutes and then getting smuggled through spy-infested Stockholm, the bomb bay of a British fighter jet might have been a relief to physicist Niels Bohr. His approach to ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

I have been to more scientific conferences than I care to count, but a recent meeting held on the island of Helgoland to celebrate the centenary of quantum mechanics is one of the strangest – in a ...

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 ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...
