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 ...

Supercooled water may be a two-for-one deal. A long-standing theory holds that liquid water at temperatures well below freezing is composed of two different arrangements of molecules, one with high ...

Physicists are fascinated with heady puzzles, from the nature of space and time to how the universe came to be. But spinning lawn sprinklers? Yes, that too. A new experiment provides an answer to a ...

Superionic water—the hot, black and strangely conductive form of ice that exists in the center of distant planets—was ...

The original version of this story appeared in Quanta Magazine. Once upon a time, long ago, the world was encased in ice. That’s the tale told by sedimentary rock in the tropics, many geologists ...

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 ...

Learning how to skip stones across a lake or pond is a time-honored childhood tradition. The underlying physics of skipping stones could also be a useful model for landing aircraft or spacecraft on ...

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 ...
