Thomas Harriot (Oxford, c. 1560 – London, 2 July 1621), also spelled Harriott, Hariot or Heriot, was an English astronomer, mathematician, ethnographer and translator who made advances within the scientific field. Thomas Harriot was recognized for his contributions in astronomy, mathematics, and navigational techniques. Harriot worked closely with John White to create advanced maps for navigation. While Harriot worked extensively on numerous papers on the subjects of astronomy, mathematics, and navigation the amount of work that was actually published was sparse. So sparse that the only publication that has been produced by Harriot was The Briefe and True Report of the New Found Land of Virginia. The premise of the book includes descriptions of English settlements and financial issues in Virginia at the time. He is sometimes credited with the introduction of the potato to the British Isles. Harriot was the first person to make a drawing of the Moon through a telescope, on 26 July 1609, over four months before Galileo Galilei.

After graduating from St Mary Hall, Oxford, Harriot travelled to the Americas, accompanying the 1585 expedition to Roanoke island funded by Sir Walter Raleigh and led by Sir Ralph Lane. Harriot was a vital member of the venture, having learned and translating the Carolina Algonquian language from two Native Americans: Wanchese and Manteo. On his return to England, he worked for the 9th Earl of Northumberland. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed.

The demon core was a spherical 6.2-kilogram (14 lb) subcritical mass of plutonium 89 millimetres (3.5 in) in diameter, that was involved in two criticality accidents, on August 21, 1945 and May 21, 1946. The core was intended for use in a third nuclear weapon, but remained in use for testing after Japan's surrender. It was designed with a small safety margin to ensure a successful explosion of the bomb. The device briefly went supercritical when it was accidentally placed in supercritical configurations during two separate experiments intended to guarantee the core was indeed close to the critical point. The incidents happened at the Los Alamos Laboratory in 1945 and 1946, both resulting in the acute radiation poisoning and subsequent deaths of scientists: Harry Daghlian and Louis Slotin. After these incidents the spherical plutonium core was referred to as the "demon core".

🔗 Songs

"Old Man Trump" is a song with lyrics written by American folk singer-songwriter Woody Guthrie in 1954. The song describes the racist housing practices and discriminatory rental policies of his landlord, Fred Trump (the father of the 45th president of the United States, Donald Trump). Although the lyrics were written in 1954, it was never recorded by Guthrie. In January 2016, Will Kaufman, a Guthrie scholar and professor of American literature and culture at the University of Central Lancashire, unearthed the handwritten lyrics while conducting research at the Woody Guthrie Archives in Tulsa, Oklahoma.

🔗 Politics 🔗 Pirate Politics 🔗 Sweden 🔗 Politics/Political parties

The Pirate Party (Swedish: Piratpartiet) is a political party in Sweden founded in 2006. Its sudden popularity has given rise to parties with the same name and similar goals in Europe and worldwide, forming the International Pirate Party movement.

The Pirate Party was initially formed to reform laws regarding copyright and patents. The party agenda includes support for strengthening the individual's right to privacy, both on the Internet and in everyday life, and the transparency of state administration. The Pirate Party has intentionally chosen to be bloc independent of the traditional left-right scale to pursue their political agenda with all mainstream parties. The party originally stayed neutral on other matters, but started broadening into other political areas in 2012.

The Pirate Party participated in the 2006 Riksdag elections and gained 0.63% of the votes, making them the third largest party outside parliament. In terms of membership, it passed the Green Party in December 2008, the Left Party in February 2009, the Liberal People's Party and the Christian Democrats in April 2009, and the Centre Party in May 2009, making it, for the time being, the third largest political party in Sweden by membership. The Pirate Party's associated youth organisation, Young Pirate (Swedish: Ung Pirat), was, for a part of 2009 and 2010, the largest political youth organisation in Sweden by membership count.

The Pirate Party came 5th in the 2009 European Parliament elections with 7.13% of the vote and 1 MEP (increasing to 2 after ratification of the Lisbon Treaty). Christian Engström became the first MEP for the party, and Amelia Andersdotter took the second seat on 1 December 2009.

Rick Falkvinge, founder of the party, stepped down on 1 January 2011 after five years as party leader, making vice leader Anna Troberg the party leader.

On 1 December 2014, Anna Troberg announced that she would not be available for re-election in 2015 after her term ended on 31 December 2014.

🔗 Law 🔗 England 🔗 Middle Ages 🔗 Middle Ages/History

The Charter of the Forest of 1217 (Latin: Carta Foresta) is a charter that re-established for free men rights of access to the royal forest that had been eroded by William the Conqueror and his heirs. Many of its provisions were in force for centuries afterwards. It was originally sealed in England by the young King Henry III, acting under the regency of William Marshall, 1st Earl of Pembroke. It was in many ways a companion document to Magna Carta, and redressed some applications of the Anglo-Norman Forest Law that had been extended and abused by William Rufus.

Graffiti is an essentially single-stroke shorthand handwriting recognition system used in PDAs based on the Palm OS. Graffiti was originally written by Palm, Inc. as the recognition system for GEOS-based devices such as HP's OmniGo 100 and 120 or the Magic Cap-line and was available as an alternate recognition system for the Apple Newton MessagePad, when NewtonOS 1.0 could not recognize handwriting very well. Graffiti also runs on the Windows Mobile platform, where it is called "Block Recognizer", and on the Symbian UIQ platform as the default recognizer and was available for Casio's Zoomer PDA.

The software is based primarily on a neography of upper-case characters that can be drawn blindly with a stylus on a touch-sensitive panel. Since the user typically cannot see the character as it is being drawn, complexities have been removed from four of the most difficult letters. "A" "F", "K" and "T" all are drawn without any need to match up a cross-stroke.

Some letters can be drawn with strokes other than the "official" ones. Two examples of these alternative strokes are the letters "V" (drawn the same only from right to left) and "X" (drawn the same as the letter "K" except reversed from right to left). These alternative strokes are frequently recognized with greater reliability.

🔗 Philosophy 🔗 Philosophy/Ethics

The hedonic treadmill, also known as hedonic adaptation, is the observed tendency of humans to quickly return to a relatively stable level of happiness despite major positive or negative events or life changes. According to this theory, as a person makes more money, expectations and desires rise in tandem, which results in no permanent gain in happiness. Brickman and Donald T. Campbell coined the term in their essay "Hedonic Relativism and Planning the Good Society" (1971). The concept dates back centuries, to such writers as St. Augustine, cited in Robert Burton's 1621 Anatomy of Melancholy: "A true saying it is, Desire hath no rest, is infinite in itself, endless, and as one calls it, a perpetual rack, or horse-mill."

The hedonic (or happiness) set point has gained interest throughout the field of positive psychology where it has been developed and revised further. Given that hedonic adaptation generally demonstrates that a person's long-term happiness is not significantly affected by otherwise impacting events, positive psychology has concerned itself with the discovery of things that can lead to lasting changes in happiness levels.

🔗 New York (state)

The Larkin Company, also known as the Larkin Soap Company, was a company founded in 1875 in Buffalo, New York as a small soap factory. It grew tremendously throughout the late 1800s and into the first quarter of the 1900s with an approach called "The Larkin Idea" that transformed the company into a mail-order conglomerate that employed 2,000 people and had annual sales of $28.6 million (equivalent to $434,986,000 in 2023) in 1920. The company's success allowed them to hire Frank Lloyd Wright to design the iconic Larkin Administration Building which stood as a symbol of Larkin prosperity until the company's demise in the 1940s.

🔗 Software 🔗 Software/Computing

Tierra is a computer simulation developed by ecologist Thomas S. Ray in the early 1990s in which computer programs compete for time (central processing unit (CPU) time) and space (access to main memory). In this context, the computer programs in Tierra are considered to be evolvable and can mutate, self-replicate and recombine. Tierra's virtual machine is written in C. It operates on a custom instruction set designed to facilitate code changes and reordering, including features such as jump to template (as opposed to the relative or absolute jumps common to most instruction sets).
