The Wikipedia article of the day for January 22, 2018 is S-50 (Manhattan Project).
The S-50 Project was the Manhattan Project’s effort to produce enriched uranium by liquid thermal diffusion during World War II. The process was developed by Philip H. Abelson and other scientists at the United States Naval Research Laboratory, and was one of three technologies for uranium enrichment pursued by the Manhattan Project. Pilot plants were built at the Anacostia Naval Air Station and the Philadelphia Navy Yard. A facility at the Clinton Engineer Works in Oak Ridge, Tennessee, was the only production-scale liquid thermal diffusion plant ever built. It could not enrich uranium sufficiently for use in an atomic bomb, but it could begin the process of enrichment that was completed by the Y-12 calutrons and the K-25 gaseous diffusion plants. It sped up the production of enriched uranium for the Little Boy bomb used in the atomic bombing of Hiroshima. This plant ceased production in September 1945, but was reopened in May 1946, and used by the Nuclear Energy for the Propulsion of Aircraft project of the US Army Air Forces before being demolished in the late 1940s.

The Wikipedia article of the day for January 21, 2018 is Saguaro National Park.
Saguaro National Park is a United States national park in southeastern Arizona that preserves Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus. The 92,000-acre (37,000 ha) park has two separate areas—the Tucson Mountain District (TMD) about 10 miles (16 km) west of the city of Tucson and the Rincon Mountain District about 10 miles (16 km) east of the city. The Rincon Mountains are part of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico; they are significantly higher and wetter than the Tucson Mountains, and support many plants and animals that do not live in the TMD. Earlier residents of and visitors to the lands in and around the park before its creation included the Hohokam, Sobaipuri, Tohono O’odham, and Apaches, as well as Spanish explorers, missionaries, miners, homesteaders, and ranchers. In 1933, President Herbert Hoover, using the Antiquities Act, established the original park, Saguaro National Monument, in the Rincon Mountains. In 1961, President John F. Kennedy added the TMD.

Reg Pollard (20 January 1903 – 9 March 1978) was a senior commander in the Australian Army, serving as Chief of the General Staff from 1960 to 1963. He was mentioned in despatches in 1941 after seeing action with the 7th Division in the Middle East. In 1942 he became senior staff officer of the division in New Guinea, and was awarded the Distinguished Service Order for his actions. Pollard’s early post-war roles involved recruit training, administration, and planning. In 1953 he took command of the Australian Army Component of the British Commonwealth Forces Korea. In 1957 he was promoted to lieutenant general and took charge of Eastern Command in Sydney. Knighted in 1961, he presided over the Army’s reorganisation as Chief of the General Staff, and helped Royal Military College, Duntroon become a degree-granting institution. In 1962, he oversaw deployment of the first team of Australian military advisors to South Vietnam. After retiring from the military in 1963, Pollard became Honorary Colonel of the Royal Australian Regiment; he served as Australian Secretary to Queen Elizabeth II during the Royal Visit in 1970.

The Wikipedia article of the day for January 19, 2018 is Sonic Spinball.
Sonic Spinball is a pinball video game developed by the Sega Technical Institute and published by Sega. It was originally released for the Mega Drive/Genesis in North America and Europe in November 1993 and in Japan the following month. It was later ported to the Game Gear and Master System in 1994 and 1995 respectively. The game has been re-released on eleven different consoles and has been included in Genesis-related compilations. The player controls Sonic the Hedgehog, who is manipulated like a pinball in various machine-like environments for most of the game, while the series antagonist Doctor Robotnik tries to enslave the population on the planet Mobius. Sonic Spinball was commissioned by Sega when it became clear that a new Sonic the Hedgehog game could not be completed in time for the 1993 holiday season, since the majority of their staff were developing Sonic the Hedgehog 3. The game was hastily developed, with most work completed within two months. It received mixed reviews upon release; most critics praised the game’s novelty and graphics but faulted its control scheme.

The Wikipedia article of the day for January 18, 2018 is Cleopatra Selene of Syria.
Cleopatra Selene (died 69 BC) was a queen of Seleucid Syria (83–69 BC). The daughter of Ptolemy VIII and Cleopatra III of Egypt, she became the queen of Egypt in 115 BC when she was married to her brother, King Ptolemy IX, and later probably married King Ptolemy X. In 103 BC, Cleopatra III established an alliance with the Seleucid ruler Antiochus VIII; Cleopatra Selene was sent to be his bride, and stayed with him until his assassination in 96 BC. The widowed queen married her previous husband’s brother, Antiochus IX, who died in 95 BC. She then married her stepson, Antiochus X, who probably died in 92 BC. She hid somewhere in Syria with her children until 83 BC, when the Seleucid thrones in Antioch and Damascus became vacant. She declared her son Antiochus XIII king, but he was deposed after the people of Antioch and Damascus, exhausted by the Seleucids’ civil wars, invited foreign monarchs to rule them. She controlled several coastal towns until she was besieged, captured and executed in 69 BC by Tigranes in Ptolemais.

The Wikipedia article of the day for January 17, 2018 is Eastbourne manslaughter.
The Eastbourne manslaughter (R v Hopley) was an 1860 legal case in Eastbourne, England, about the death of a teenage pupil at the hands of his teacher, Thomas Hopley. Reginald Cancellor’s parents gave Hopley permission to use corporal punishment to overcome what he perceived as the boy’s stubbornness. After the boy died, the teacher insisted that the beating was justifiable and that he was not guilty of any crime. An inquest into Cancellor’s death began when his brother requested an autopsy. As a result of the inquest Hopley was arrested and charged with manslaughter. He was found guilty at trial and sentenced to four years in prison. Hopley’s conviction was upheld by the Court of King’s Bench (Chief Justice Alexander Cockburn pictured), which said that a schoolmaster “may for the purpose of correcting what is evil in the child, inflict moderate and reasonable corporal punishment.” The trial was sensationalised by the Victorian press and incited debate over the use of corporal punishment in schools. Physical discipline was officially banned in British schools more than a century later.

The Wikipedia article of the day for January 16, 2018 is Illinois Centennial half dollar.
The Illinois Centennial half dollar is a commemorative fifty-cent piece struck by the United States Bureau of the Mint in 1918. The obverse side, depicting Abraham Lincoln, was designed by Chief Engraver George T. Morgan; the reverse image, based on the Seal of Illinois, was done by his assistant and successor, John R. Sinnock. Morgan’s design is based on a statue by Andrew O’Connor. The State of Illinois asked for a commemorative to mark the centennial of its 1818 statehood. In 1918, after legislation was enacted, the two engravers produced designs, but Treasury Secretary William G. McAdoo required changes, not all of which were made. The coins were minted in August 1918, and were sold to the public for one dollar each. Though many were held by a bank until 1933, all were sold, and profits were used to cover the cost of local centennial celebrations or to help those in need because of World War I. Later writers have generally admired the coin, considering it one of the more handsome American commemoratives. It is valued in the hundreds of dollars today, and occasionally trades for more.
