In 1912 Henrietta Leavitt showed that brighter Cepheid stars pulse more slowly. That one relation became the first rung of the cosmic distance ladder, and it still sits at the...

In 1939 Lise Meitner and Otto Frisch explained why uranium hit by neutrons produced barium: the nucleus had split. Otto Hahn alone received the 1944 Nobel Prize in Chemistry for...

How Did Rømer Measure the Speed of Light with Io?
In 1676, at the Paris Observatory, Ole Rømer noticed that eclipses of Jupiter’s moon Io came late when Earth was moving away from Jupiter and early when it was approaching....

Marie Curie’s Discoveries: Radioactivity, Polon...
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...

Jocelyn Bell Burnell and the Discovery of Pulsars
In late 1967 Jocelyn Bell, a PhD student at Cambridge, noticed a strange signal among miles of chart paper. It turned out to be a pulsar, a spinning neutron star....

Newton, Galileo and Kepler: What Each Got Right...
Kepler found that planets follow ellipses with the Sun at a focus. Galileo built the kinematics of free fall and projectile motion. Newton’s Principia united them under universal gravitation and...
