The first surviving daguerrotype photograph showing details of the sun are taken by French physicists Armand Fizeau and Léon Foucault. The five inch (12cm) image has an exposure of one sixtieth of a second, and shows the umbra/penumbra structure of several sunspots, as well as limb darkening. The photographic process is new; Daguerre had only just perfected the daguerrotype process in 1838.

George B. Brayton of Boston, Massachusetts receives a US patent for a gas-powered engine. (US No. 125,166) He invented this first American commercial internal combustion engine, which he would later manufacture and sell. The engine injects a pressurized air-fuel mixture from a reservoir, into the water-cooled cylinder in which it is ignited. Its principle of continuous ignition later will become the basis for the turbine engine.

Dr. John William Mauchly and J. Presper Eckert, Jr. submit a memo to the US Army describing an Electronic Difference Analyzer which could calculate ballistic trajectories in thirty seconds, 14.5 minutes less than the best method the Army had in use. The proposed machine would fully utilize about eighteen thousand vacuum tubes simultaneously. The memo would evolve into a $400,000 contract awarded to the Moore School of the University of Pennsylvania from the U.S. Army. In 1946, the Electronic Numerical Integrator and Calculator (ENIAC) will be unveiled.

Velcro, the hook-and-loop fastener, is released. It was developed by Swiss engineer Georges de Mestral, who noticed how thistle burrs clung to his clothing during a hike in the mountains. Using a microscope, he discovered their natural hook-like shape. In 1948, he began working with a local weaver from a textile plant to design a “locking tape.” The pair make accidentally discover that nylon form industructable hooks when sewn under ultraviolet light. The trademarked name Velcro comes from “vel” or velvet and “cro” from the French word crochet which means hook.
1980
The Microsoft Corporation announces the Z80 SoftCard their first hardware product, a microprocessor on a printed circuit board that plugged into the Apple II personal computer. The SoftCard allowed programs running under the CP/M operating system (included with the card, as was Microsoft BASIC) to run on the 6502-based Apple II with only minor modifications. In particular, the word processor WordStar was so popular that people bought the SoftCard and a companion “80-column card” just to run it. At one point, SoftCard will bring in about half of Microsoft’s total revenue. It will be discontinued in 1986. Price: US$349.00
