Eric Arthur Roberts (18 June 1907 – 17 or 18 December 1972) was an MI5 agent during the Second World War under the alias Jack King. By posing as a Gestapo agent and infiltrating fascist groups in the UK, Roberts was able to prevent secret information finding its way to Germany. Roberts continued to work for the security services after the war, particularly in Vienna, but it was a time of great anxiety in the services because of the suspicions surrounding double agents such as the Cambridge spy ring.

Roberts never felt completely accepted by MI5 because of his social background and a desk role did not suit him as well as his wartime role had. He is the subject of the biography Agent Jack (2018) by Robert Hutton, and his adventures were the inspiration for the novel Our Friends In Berlin by Anthony Quinn and for a major character in the novel Transcription by Kate Atkinson.

Scientism is the promotion of science as the best or only objective means by which society should determine normative and epistemological values. The term scientism is generally used critically, implying a cosmetic application of science in unwarranted situations considered not amenable to application of the scientific method or similar scientific standards.

The Law of Jante (Danish: Janteloven) is a code of conduct known in Nordic countries that characterizes not conforming, doing things out of the ordinary, or being overtly personally ambitious as unworthy and inappropriate. The attitudes were first formulated in the form of the ten rules of Jante Law by the Dano-Norwegian author Aksel Sandemose in his satirical novel A Fugitive Crosses His Tracks (En flyktning krysser sitt spor, 1933), but the actual attitudes themselves are older. Sandemose portrays the fictional small Danish town Jante, which he modelled upon his native town Nykøbing Mors in the 1930s, where nobody was anonymous, which is typical of all small towns and communities.

Used generally in colloquial speech in the Nordic countries as a sociological term to denote a social attitude of disapproval towards expressions of individuality and personal success, it emphasizes adherence to the collective.

🔗 United States 🔗 Africa 🔗 African diaspora 🔗 United States/Kentucky 🔗 Africa/Liberia

Kentucky in Africa was a colony in present-day Montserrado County, Liberia, founded in 1828 and settled by American free people of color, many of them former slaves. A state affiliate of the American Colonization Society, the Kentucky State Colonization Society raised money to transport people of color from Kentucky—freeborn volunteers as well as enslaved individuals set free on the condition that they leave the United States for Liberia. The Kentucky society bought a 40-square-mile (100 km²) site along the Saint Paul River (quite near the site of the present-day capital city of Monrovia) and named it Kentucky in Africa. Clay-Ashland. named after Henry Clay's Ashland Plantation, was the colony's primary settlement.

Notable residents of Kentucky in Africa include Alfred Francis Russell, the 10th President of Liberia, and William D. Coleman, the 13th President of Liberia, whose family settled in Clay-Ashland after emigrating from Fayette County, Kentucky.

Kentucky in Africa was annexed by Liberia in about 1847.

🔗 Photography 🔗 Photography/History of photography 🔗 Gemology and Jewelry

A stanhope or stanho-scope is an optical device that enables the viewing of microphotographs without using a microscope. They were invented by René Dagron in 1857. Dagron bypassed the need for an expensive microscope to view the microscopic photographs by attaching the microphotograph at the end of a modified Stanhope lens. He called the devices bijoux photo-microscopiques or microscopic photo-jewelry.

🔗 Extinction 🔗 Evolutionary biology 🔗 Ecology

Conservation-induced extinction is where efforts to save endangered species lead to the extinction of other species. This mostly threatens the parasite and pathogen species that are highly host-specific to critically endangered hosts. When the last individuals of a host species are captured for the purpose of captive breeding and reintroduction programs, they typically undergo anti-parasitic treatments to increase survival and reproductive success. This practice may unintentionally result in the extinction of the species antagonistic to the target species, such as certain parasites. It has been proposed that the parasites should be reintroduced to the endangered population. A few cases of conservation-induced extinction have occurred in parasitic lice.

The terms Androgynous Peripheral Attach System (APAS), Androgynous Peripheral Assembly System (APAS) and Androgynous Peripheral Docking System (APDS) are used interchangeably to describe a Russian family of spacecraft docking mechanisms, and are also sometimes used as generic names for any docking system in that family. A system similar to APAS-89/95 is used by the Chinese Shenzhou spacecraft.

🔗 Physics

Coulombic explosions are a mechanism for transforming energy in intense electromagnetic fields into atomic motion and are thus useful for controlled destruction of relatively robust molecules. The explosions are a prominent technique in laser-based machining, and appear naturally in certain high-energy reactions.

🔗 Robotics

Micromouse is an event where small robot mice solve a 16×16 maze. It began in the late 1970s. Events are held worldwide, and are most popular in the UK, U.S., Japan, Singapore, India, South Korea and becoming popular in subcontinent countries such as Sri Lanka.

The maze is made up of a 16×16 grid of cells, each 180 mm square with walls 50 mm high. The mice are completely autonomous robots that must find their way from a predetermined starting position to the central area of the maze unaided. The mouse needs to keep track of where it is, discover walls as it explores, map out the maze and detect when it has reached the goal. Having reached the goal, the mouse will typically perform additional searches of the maze until it has found an optimal route from the start to the finish. Once the optimal route has been found, the mouse will run that route in the shortest possible time.

Competitions and conferences are still run regularly.
