||1904: Cyril Stanley Smith born ... metallurgist who in 1943-44 determined the properties and technology of plutonium and uranium, the essential materials in the atomic bombs that were first exploded in 1945. Smith already then had 15 years of experience as a research metallurgist with the American Brass Co., during which time he studied properties of alloys and their microstructure. In WW II, he joined the Los Alamos Laboratory at its inception (1943). The properties and technology of plutonium had to be conducted with extremely limited quantities of available material. Smith and his group found it was unique, with five different allotropic forms with huge density differences between them. Postwar, he organized the Institute for the Study of Metal at the Univ. of Chicago.

1903: Physicist, inventor, and academic John Vincent Atanasoff born. He will invent the Atanasoff–Berry computer, the first electronic digital computer.
1947: Physicist and academic Max Planck dies. He made many contributions to theoretical physics, and earned fame as the originator of quantum theory.
1957: Clock Head 2 stops math criminals from interfering with the launch of Sputnik 1.
1957: Space Race: Launch of Sputnik 1, the first artificial satellite to orbit the Earth.
2006: Steganographic analysis of the Superimposed Fraunhofer stamp reveals "seven hundred to eight hundred kilobytes" of previously unknown Gnomon algorithm functions related to color. These functions will quickly find application in the detection and prevention of crimes against light.
2018: Green Spiral 5 voted Picture of the Day by the citizens of New Minneapolis, Canada.
