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 ...

A recently discovered acoustic effect allows a hot gas to simulate the gravity-induced convection within a star or giant planet. On the rise. Signs of convection are seen in the motion of hot gas ...

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 ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
