Mary Jackson (1921–2005) was an American mathematician and aerospace engineer at the National Advisory Committee for Aeronautics and its successor, NASA. She worked at Langley Research Center in Hampton, Virginia, for most of her career. She started as a computer at the segregated West Area Computing division in 1951. In 1958, after taking engineering classes, she became NASA's first black female engineer. Jackson had earned the most senior engineering title available by 1979 and realized she could not earn further promotions without becoming a supervisor. She accepted a demotion to become a manager of both NASA's federal women's program and the affirmative action program. Her work sought to influence the career paths of women in science, engineering, and mathematics positions at NASA. Jackson is one of the leading characters in the 2016 book Hidden Figures and one of the three protagonists in the book's film adaptation, released the same year. This NASA photograph of Jackson was taken in 1979.Photograph credit: NASA; restored by Adam Cuerden

The battle of Cane Hill was fought during the American Civil War on November 28, 1862, near the town of Cane Hill, Arkansas. Union troops under James G. Blunt had pursued Confederate troops commanded by Thomas C. Hindman into northwestern Arkansas, and Hindman saw an opportunity to attack Blunt while the latter was isolated. Confederate cavalry under John S. Marmaduke moved to Cane Hill to collect supplies. Blunt moved to attack Marmaduke on November 27. The Union advance made contact with Confederate troopers the next morning. The Confederates fell back to an elevation known as Reed's Mountain. Blunt continued to pursue after the Confederates abandoned Reed's Mountain, but his leading elements ran into an ambush. The Confederates then presented a flag of truce as a ruse to buy time. Hindman's army and Blunt's reinforced command fought the Battle of Prairie Grove on December 7, which retained Union control of Missouri and northwestern Arkansas. (Full article...)

... that German soldiers did not believe that Francis L. Sampson(pictured) was a non-combatant after his capture during the D-Day landings, because they had never seen a paratrooper chaplain before?
... that the hips of some 19th-century Fijian young women were tattooed with veiqia when they reached puberty?

The ocellated turkey (Meleagris ocellata) is a species of turkey residing primarily in the Yucatán Peninsula, Mexico, as well as in parts of Belize and Guatemala. It is a relative of the North American wild turkey (Meleagris gallopavo), although it is somewhat smaller. The body feathers of both sexes are a mixture of bronze and green iridescent color, with neither sex possessing the beard typically found in wild turkeys. Tail feathers of both sexes are bluish-grey with an eye-shaped, blue-bronze spot near the end with a bright gold tip. These spots, or ocelli (for which the ocellated turkey is named) have been likened to the patterning typically found on peafowl. This ocellated turkey was photographed near Tikal in the Petén region of Guatemala.
