The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

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 ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

A century ago, the Stern-Gerlach experiment established the truth of quantum mechanics. Now it’s being used to probe the clash of quantum theory and gravity. Before Erwin Schrödinger’s cat was ...

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

Neutrinos are some of nature’s most elusive particles. One hundred trillion fly through your body every second, but each one has only a tiny chance of jostling one of your atoms, a consequence of the ...

Science experiments that push materials and reactions to dramatic limits. So this is why Trump didn’t want to release the ...

A beam of light was sent through a maze of mirrors and detectors. Then scientists changed the setup after the photon had already passed through. Somehow the photon adjusted its behavior as if it had ...

A new study suggests subatomic particles called muons are breaking the laws of physics. This may mean a mysterious force is affecting muons, which would make our understanding of physics incomplete.

College professors these days face an ever-higher bar to grab the attention of their students, forced to compete with the stimuli of smartphones and laptops in large lecture halls. But when your ...
