Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

At first glance, however, quantum physics does not really seem to adhere to this rule: Mathematically speaking, entropy in quantum systems always remains the same. A research team at TU Wien has now ...

In the 1960s, a group of physicists and historians began a massive project meant to catalogue and record the history of quantum physics. It was called Sources for History of Quantum Physics (SHQP). As ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

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 ...
