The Ladies’ Mercury, the first periodical for women, is published in London

The Ladies’ Mercury appeared in London in late February 1693, a single double-sided sheet promising answers to questions on love, marriage, and behavior from women readers. It ran just four issues over four weeks, fielding queries in what may be the earliest advice-column format aimed at women. A small pamphlet that helped establish women as a reading public worth addressing directly.

Portrait of Ole Rømer (1644-1710), for article on speed of light finite

Ole Rømer proves the speed of light is finite, changing astronomy forever

The speed of light was first measured in November 1676, when Danish astronomer Ole Rømer announced to Paris’s Royal Academy that light takes time to cross space. By tracking tiny delays in the eclipses of Jupiter’s moon Io, he estimated light crossed Earth’s orbit in about 22 minutes. It was humanity’s first glimpse that the cosmos speaks in delayed signals.

Title page of Sylva, for article on forest conservation

John Evelyn presents Sylva to the Royal Society, launching forest conservation

In 1662, English writer John Evelyn stood before London’s Royal Society and warned that England’s forests were vanishing under the weight of shipbuilding, iron-smelting, and careless felling. His paper Sylva called not just for restraint but for active replanting — one of the earliest formal Western arguments that nature must be tended, not simply taken.

Galileo Galilei overturns ancient physics and reveals a heliocentric cosmos

Galileo Galilei, in early 17th-century Italy, pointed a homemade telescope at the sky and began dismantling a thousand years of cosmic certainty. He spotted four moons circling Jupiter, watched Venus move through phases, and rolled balls down ramps to uncover the laws of motion. His habit of measuring rather than assuming became the backbone of modern science.

Picture of Sun and planets, for article on Kepler's laws of planetary motion

Kepler’s laws of planetary motion reshape how humans understand the solar system

Kepler’s laws of planetary motion emerged between 1609 and 1621, when a German mathematician working with a dead Danish astronomer’s data realized the planets don’t move in circles. Studying Mars, Johannes Kepler found an eight-arc-minute discrepancy he refused to ignore, and followed it to elliptical orbits. Four centuries later, NASA still uses his math to plot spacecraft trajectories.
