Marie Curie did not discover radioactivity. Henri Becquerel found the rays in 1896. What she did was turn a strange effect into a science: she showed the rays were an...

Neutrinos are the most elusive particles we know of. Thousands of billions stream through your body every second without touching you. Pauli invented them in 1930 to save energy conservation,...

In 1934 Hideki Yukawa asked why the force that holds the nucleus together reaches only about the width of a proton. His answer: a force carried by a particle with...

The Ising model is the simplest picture of a magnet: a grid of arrows that can only point up or down, each wanting to match its neighbours. Heat scrambles them;...

A perfect lens still cannot focus light to a point. Waves spread out after passing through any opening, so every star becomes a tiny bright disk with faint rings, the...
