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 ...

Quantum entanglement is one of the strangest discoveries in modern physics — a phenomenon where two particles behave as a single object, even across vast distances. Einstein rejected it, calling it ...

Researchers have found that a swirling water vortex can force opposing waves to form rotating lines of stillness across an entire tank. That result turns a famously hard-to-see quantum effect into ...

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 ...
