For years, the observer effect has been twisted into a seductive idea: that consciousness somehow creates reality. But the ...

For the first time, scientists have created oxygen-28, a rare oxygen isotope that has 12 more neutrons than oxygen-16, the most common form of oxygen on the planet. This newly created "heavy" oxygen ...

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 ...

Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable. How does ...

There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the ...

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 ...

The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience will, of necessity, be something of a distortion. The question ...

Quantum physicist Mario Krenn remembers sitting in a café in Vienna in early 2016, poring over computer printouts, trying to make sense of what MELVIN had found. MELVIN was a machine-learning ...

The long-awaited first results from the Muon g-2 experiment at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists’ best ...
