From today's featured articleThe double sovereign is a gold coin of the United Kingdom with a nominal value of two pounds sterling (£2). It features the reigning monarch on its obverse and, most often, Benedetto Pistrucci's depiction of Saint George and the Dragon on the reverse (pictured). It was rarely issued in the first century and a half after its debut in 1820, usually in a new monarch's coronation year or to mark the institution of a new coinage portrait of the monarch. In addition to the usual coinage in Britain, specimens were struck at Australia's Sydney Mint in 1887 and 1902. Most often struck as a proof coin, the double sovereign has been issued for circulation in only four years, and few examples worn from commercial use are known. It is now a collector and bullion coin, and has been struck by the Royal Mint most years since 1980. In some years, it has not been issued and the Royal Mint instead placed gold versions of the commemorative £2 piece in the annual gold proof sets. (Full article...)

The Turing Award is an annual prize given by the Association for Computing Machinery for contributions of lasting and major technical importance to computer science. It is generally recognized as the highest distinction in the field of computer science and is often referred to as the "Nobel Prize of Computing". The award is named after Alan Turing (pictured), who was a British mathematician and reader in mathematics at the University of Manchester. Turing is often credited as being the founder of theoretical computer science and artificial intelligence, and a key contributor to the Allied cryptanalysis of the Enigma cipher during World War II. The first recipient, in 1966, was Alan Perlis of Carnegie Mellon University. The youngest recipient was Donald Knuth, who won in 1974 at the age of 36, while the oldest recipient was Alfred Aho, who won in 2020 at the age of 79. As of 2024, 77 people have been awarded the Turing Prize. (Full list...)
