Light Bulb Race: Edison v. Swan
February 3, 1879
Thomas Edison is credited with having invented the incandescent light bulb. However, scientists and inventors have actually been working on developing a long-lasting and cost effective bulb for almost eighty years before Edison joins the race. In fact, Humphrey Davy develops the first incandescent lamp in 1802, but it requires too much electricity to power it for practical purposes. On February 3, 1879 in England, Joseph Swan publicly demonstrates a working incandescent light with a carbon-based filament.
Later the same year, in his lab in Menlo Park, California, Thomas Edison develops a similar bulb and an effective electrical system to power it. He subsequently sues Swan for patent infringement, but the two eventually join forces to create Edison-Swan United, one of the world’s largest manufacturers of lightbulbs.

The Universe is Created
April 27, 4977 B.C.
The 17th century German mathematician and astronomer Johannes Kepler calculates the date of the universe’s creation to be April 27, 4977 B.C. Though these calculations are off by about 13.7 billion years, Kepler will be remembered for another body of work. Kepler’s theories explaining planetary motion become the basis for Isaac Newton’s theory of universal gravitation.
