A subtle timing flash may expose the Unruh effect. The approach ties ordinary lab tools to deep quantum physics. Researchers ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

A blazar is an extraordinarily bright object with a supermassive black hole at its core. Some of the matter falling into the ...

Deep underground in southern China, there is a 20,000-ton tank of liquid that can detect neutrinos. Named JUNO, the ...

This is Scientific American’s 60-Second Science podcast. I’m Clara Moskowitz. There are probably many more particles out there in the universe than the ones we know about. And today physicists got a ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A ...

A new quantum physics experiment just lent evidence to a mind-boggling idea that was previously limited to the realm of theory, according to the MIT Technology Review — that under the right conditions ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...

UChicago physics Prof. Bonnie Fleming, who is also the chief research officer at Fermi National Accelerator Laboratory, is ...

And that early result came from only 59 days of data.

This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...
