Einstein rejected it, calling it “spooky action at a distance,” but decades of experiments proved him wrong. From satellite tests to lab-created photon pairs, entanglement continues to defy common ...

This experiment uses a warm liquid on ice to explore how heat actually moves and dissipates. Instead of melting evenly, the ice reacts in unexpected patterns that reveal strange thermal behavior. It’s ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

From a particle smasher encircling the moon to an “impossible” laser, five scientists reveal the experiments they would run ...

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 ...

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 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 ...

Does anyone know of an app for simple physics experiments like Newton, but that'd allow measurement of free objects colliding? Newton only allows its springs to collide with its balls if the two are ...
