For decades physicists assumed that the mirror image of any experiment would behave exactly like the original. In 1957 Chien-Shiung Wu and her team proved that the weak force breaks...

In 1900 Pyotr Lebedev showed that light pushes on a mirror, exactly as Maxwell predicted. Here is how big that push is, why it was so hard to measure, how...

How do you measure gravity with a swinging bar when nobody can say exactly how long the bar is? Henry Kater’s 1817 trick: hang it both ways up and tune...

In October 1971 two scientists bought airline seats for four atomic clocks and flew them around the world, once eastward and once westward. When the clocks came home, they no...

Sidereus Nuncius: What Galileo Saw in 1610
In March 1610 Galileo published a short book of telescope observations: a mountainous Moon, a Milky Way made of stars and four moons circling Jupiter. Here is what he saw,...

Planck's 1900 Quantum Hypothesis, Step by Step
In late 1900 Max Planck found the formula for black-body radiation and then, to justify it, split energy into chunks of size hν. Here is the sequence of events, the...
