Jules Verne

French author Jules Verne, born on February 8, 1828, is considered the father of science fiction. Many of his 19th-century works forecast amazing scientific feats–feats that were actually carried out in the 20th century–with uncanny accuracy. Verne’s 1865 book From the Earth to the Moon told the story of a space ship that is launched from Florida to the moon and that returns to Earth by landing in the ocean. An illustration from the original version of the book is shown above. Something of a scientist and traveler himself, Verne’s 1870 work about a submarine, Twenty Thousand Leagues Under the Sea, and Around the World in Eighty Days also foretold technological advances that seemed fantastic at the time. Jules Verne died in 1905.

today’s birthday: Johannes Kepler (1571)

Johannes Kepler (1571)

Described by famed astronomer Carl Sagan as “the first astrophysicist and the last scientific astrologer,” Johannes Kepler was a German astronomer, mathematician, and astrologer. A key figure in the scientific revolution, Kepler derived three famous laws of planetary motion, which, among other things, established that the planets travel around the Sun in elliptical rather than circular orbits. When Kepler was six, his mother, who was later tried for witchcraft, took him to see what phenomenon? More… Discuss

Opalia (2014)

The ancient Roman fertility goddess Ops was known by several different names—among them Rhea, Cybele, Bona Dea, Magna Mater, Thya, and Tellus. She married Saturn and was the mother of Jupiter. She is usually portrayed as a matron, with a loaf of bread in her left hand and her right hand opened as if offering assistance. Not much is known about what actually took place during the Opalia, but it appears that women played an important role in the festival. Because Ops was a fertility goddess, she was often invoked by touching the earth. More… Discuss

Philosophiae Naturalis Principia Mathematica Published (1687)

Newton’s Principia represents one of the greatest milestones in the history of science and marked the beginning of the modern period of mechanics and astronomy. The text includes Newton’s three famous laws of motion, treatises on dynamics and fluid motion, the unification of terrestrial and celestial mechanics under the principle of gravitation, and an explanation of Kepler’s laws of planetary motion. Principia grew out of Newton’s correspondence with what famous astronomer? More… Discuss

Gabrielle-Émilie Le Tonnelier de Breteuil, Marquise du Châtelet (1706)

The wife of a French marquis, du Châtelet defied convention in both her personal and professional life. She was a mathematician and physicist and wrote a number of scientific treatises as well as a translation of Isaac Newton‘s Principia Mathematica. She had several extramarital affairs—the most enduring of which was with philosopher and writer Voltaire, who once described her as “a great man whose only fault was being a woman.” How did she once think her way out of a gambling debt? More… Discuss


Newton’s Rings

Newton’s Rings

When a curved glass surface, such as a convex lens, is placed against a flat piece of glass and illuminated by monochromatic light, a series of alternating bright and dark concentric bands, known as Newton’s rings, appears around the point of contact between the curved and flat glass. Though several scientists had observed the phenomenon before him, it was named for Isaac Newton, who analyzed it in detail. Why are the outer rings usually spaced more closely together than the inner rings? More… Discuss

Today’s Birthday: GOTTFRIED WILHELM LEIBNIZ (1646)

Gottfried Wilhelm Leibniz (1646)

Leibniz was a German philosopher and mathematician who greatly expanded the field of calculus. He also perfected the binary number system—the basis for modern computing—and constructed one of the first practical calculators. A jack-of-all-trades, Leibniz worked on mechanical devices, delved into the study of logic, was a historian and lawyer at times, and is considered one of the fathers of geology. In the early 1700s, he became embroiled in a controversy with Isaac Newton over what issue? More… Discuss
