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 ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

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 ...

Anne L’Huillier of Lund University, Pierre Agostini of The Ohio State University, and Ferenc Krausz of the Max Planck Institute of Quantum Optics won this year’s Nobel Prize in Physics “for ...

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser ...

Researchers from Skoltech and the Shanghai Institute of Optics and Fine Mechanics have developed an approach that helps optimize the parameters of a laser-plasma source of attosecond pulses—ultrashort ...

Arthur Compton (left, shown here with Francis Simon) used this equipment to prove that light, in the form of x rays and gamma rays, acts like a stream of tiny billiard balls—not waves—when it scatters ...

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 ...

Temporal measurements in conditions similar to those in the Sun rebut a leading hypothesis for why models and experiments disagree on how much light iron absorbs. Figure 1: With a surface temperature ...

Quantum physicists have measured negative time in a remarkable quantum experiment that is reshaping discussions around quantum mechanics, photon behavior, and the nature of time itself. The study, ...

After years of searching, scientists at the Micro Booster Neutrino Experiment (MicroBooNE) have ruled out the possibility of the existence of a sterile neutrino, a hypothetical particle that had long ...
