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 ...

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 ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

New research offers an intriguing variation on the famous experiment, which proved light behaves as both a particle and a wave. Reading time 2 minutes A team of physicists has recreated a classic ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

The classic double-slit experiment of quantum physics involves shining light through two narrow gaps to show that it can behave as a wave – now it seems the slits can be entirely replaced by a single ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Baryons, composite particles made up of ...

In this 2011 image, a NASA engineer looks on as the first six of the James Webb Space Telescope's 18 mirror segments are prepped to begin their final cryogenic testing. Engineers spent three decades ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...
