A pandemic (from Greek πᾶν pan "all" and δῆμος demos "people") is a disease epidemic that has spread across a large region, for instance multiple continents, or worldwide. A widespread endemic disease with a stable number of infected people is not a pandemic. Further, flu pandemics generally exclude recurrences of seasonal flu.

Throughout history, there have been a number of pandemics of diseases such as smallpox and tuberculosis. One of the most devastating pandemics was the Black Death (also known as The Plague), which killed an estimated 75–200 million people in the 14th century. Other notable pandemics include the 1918 influenza pandemic (Spanish flu) and the 2009 flu pandemic (H1N1). Current pandemics include HIV/AIDS and the 2019 coronavirus disease, which was declared a pandemic on 11 March 2020 by the World Health Organization (WHO).

🔗 Neuroscience

The frequency format hypothesis is the idea that the brain understands and processes information better when presented in frequency formats rather than a numerical or probability format. Thus according to the hypothesis, presenting information as 1 in 5 people rather than 20% leads to better comprehension. The idea was proposed by German scientist Gerd Gigerenzer, after compilation and comparison of data collected between 1976–1997.

🔗 Computer science 🔗 Time

In computer science, time formatting and storage bugs are a class of software bugs which may cause time and date calculation or display to be improperly handled. These are most commonly manifestations of arithmetic overflow, but can also be the result of other issues. The most well-known consequence of bugs of this type is the Y2K problem, but many other milestone dates or times exist that have caused or will cause problems depending on various programming deficiencies.

🔗 Video games

The Interton Video Computer 4000 (officially abbreviated as Interton VC 4000) is an 8-bit ROM cartridge-based second-generation home video game console that was released in Germany, England, France, Spain, Austria, the Netherlands and Australia in 1978 by German hearing aid manufacturer Interton. The console is quite obscure outside Germany, but many software-compatible systems can be found in numerous European countries (see versions of the 1292 Advanced Programmable Video System). The console is the successor of the Interton Video 3001 and was sold for 298DM and discontinued in 1983.

It is unknown if Interton designed and produced the Interton VC 4000 within their own rights, or if they were sold the rights to design and produce it. This is because many other foreign brands have produced "clones" of this system in the preceding years.

The Interton VC 4000's power comes from a Signetics 2650 CPU (which is the same as an Arcadia 2001) and a Signetics 2636 gaming video controller. Both controllers contain a 12-button keypad, two fire buttons, and a joystick. Inside the systems control panel, there are four different buttons: the ON/OFF switch, RESET, SELECT, and START.

🔗 United States 🔗 Law 🔗 Linux

In a series of legal disputes between SCO Group and Linux vendors and users, SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell, and Red Hat filed claims against SCO.

On August 10, 2007, a federal district court judge in SCO v. Novell ruled on summary judgment that Novell, not the SCO Group, was the rightful owner of the copyrights covering the Unix operating system. The court also ruled that "SCO is obligated to recognize Novell's waiver of SCO's claims against IBM and Sequent". After the ruling, Novell announced they had no interest in suing people over Unix and stated "We don't believe there is Unix in Linux". The final district court ruling, on November 20, 2008, affirmed the summary judgment, and added interest payments and a constructive trust.

On August 24, 2009, the U.S. Court of Appeals for the Tenth Circuit partially reversed the district court judgment. The appeals court remanded back to trial on the issues of copyright ownership and Novell's contractual waiver rights. The court upheld the $2,547,817 award granted to Novell for the 2003 Sun agreement.

On March 30, 2010, following a jury trial, Novell, and not The SCO Group, was unanimously found to be the owner of the UNIX and UnixWare copyrights. The SCO Group, through bankruptcy trustee Edward Cahn, decided to continue the lawsuit against IBM for causing a decline in SCO revenues.

On March 1, 2016, SCO's lawsuit against IBM was dismissed with prejudice; SCO filed an appeal later that month.

Katarina Vilioni (died 1342) was one of the first Europeans known to have resided in China. She was apparently a member of a Genoese trading family that lived in Yangzhou during the mid-14th century.

Vilioni is known through her tombstone, which was rediscovered at Yangzhou in 1951. It suggests that Vilioni died in 1342 and was the daughter of a man named Domenico Vilioni.

Gödel's ontological proof is a formal argument by the mathematician Kurt Gödel (1906–1978) for the existence of God. The argument is in a line of development that goes back to Anselm of Canterbury (1033–1109). St. Anselm's ontological argument, in its most succinct form, is as follows: "God, by definition, is that for which no greater can be conceived. God exists in the understanding. If God exists in the understanding, we could imagine Him to be greater by existing in reality. Therefore, God must exist." A more elaborate version was given by Gottfried Leibniz (1646–1716); this is the version that Gödel studied and attempted to clarify with his ontological argument.

Gödel left a fourteen-point outline of his philosophical beliefs in his papers. Points relevant to the ontological proof include

4. There are other worlds and rational beings of a different and higher kind.

5. The world in which we live is not the only one in which we shall live or have lived.

13. There is a scientific (exact) philosophy and theology, which deals with concepts of the highest abstractness; and this is also most highly fruitful for science.

14. Religions are, for the most part, bad—but religion is not.

The Georgia Guidestones are a granite monument erected in 1980 in Elbert County, Georgia, in the United States. A set of 10 guidelines is inscribed on the structure in eight modern languages and a shorter message is inscribed at the top of the structure in four ancient language scripts.

The monument stands at an approximate elevation of 750 feet (230 m) above sea level, about 90 miles (140 km) east of Atlanta, 45 miles (72 km) from Athens, Georgia and 9 miles (14 km) north of the center of the city of Elberton.

One slab stands in the center, with four arranged around it. A capstone lies on top of the five slabs, which are astronomically aligned. An additional stone tablet, which is set in the ground a short distance to the west of the structure, provides some notes on the history and purpose of the guidestones. The structure is sometimes referred to as an "American Stonehenge". The monument is 19 feet 3 inches (5.87 m) tall, made from six granite slabs weighing 237,746 pounds (107,840 kg) in all. The anonymity of the guidestones' authors and their apparent advocacy of population control, eugenics, and internationalism have made them a target for controversy and conspiracy theory.

🔗 Philosophy 🔗 Psychology

Kettle logic (la logique du chaudron in the original French) is a rhetorical device wherein one uses multiple arguments to defend a point, but the arguments are inconsistent with each other.

Jacques Derrida uses this expression in reference to the humorous "kettle-story", that Sigmund Freud relates in The Interpretation of Dreams (1900) and Jokes and Their Relation to the Unconscious (1905).

Hedy Lamarr (), born Hedwig Eva Maria Kiesler (November 9, 1914 – January 19, 2000), was an Austrian-born American actress, inventor and film producer. She was part of 30 films in an acting career spanning 28 years, and co-invented an early version of frequency-hopping spread spectrum.

After a brief early film career in Czechoslovakia, including the controversial Ecstasy (1933), she fled from her husband, a wealthy Austrian ammunition manufacturer, and secretly moved to Paris. Traveling to London, she met Louis B. Mayer, head of Metro-Goldwyn-Mayer (MGM) studio, who offered her a movie contract in Hollywood, where he began promoting her as the "world's most beautiful woman".

She became a star with her performance in Algiers (1938), her first film made in the United States. Her MGM films include Lady of the Tropics (1939), Boom Town (1940), H.M. Pulham, Esq. (1941), and White Cargo (1942). Dismayed with her MGM contract, Lamarr co-founded a new production studio and starred in its films including The Strange Woman (1946), and Dishonored Lady (1947). Her greatest success was as Delilah in Cecil B. DeMille's Samson and Delilah (1949). She also acted on television before the release of her final film, The Female Animal (1958). She was honored with a star on the Hollywood Walk of Fame in 1960.

At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, intended to use frequency-hopping spread spectrum technology to defeat the threat of jamming by the Axis powers. She also helped to improve aviation designs for Howard Hughes while they dated during the war. Although the US Navy did not adopt Lamarr and Antheil's invention until 1957, various spread-spectrum techniques are incorporated into Bluetooth technology and are similar to methods used in legacy versions of Wi-Fi. Recognition of the value of their work resulted in the pair being posthumously inducted into the National Inventors Hall of Fame in 2014.
