Kilroy was here is a meme that became popular during World War II, typically seen in graffiti. Its origin is debated, but the phrase and the distinctive accompanying doodle became associated with GIs in the 1940s: a bald-headed man (sometimes depicted as having a few hairs) with a prominent nose peeking over a wall with his fingers clutching the wall.

"Mr Chad" or just "Chad" was the version that became popular in the United Kingdom. The character of Chad may have been derived from a British cartoonist in 1938, possibly pre-dating "Kilroy was here". According to Dave Wilton, "Some time during the war, Chad and Kilroy met, and in the spirit of Allied unity merged, with the British drawing appearing over the American phrase." Other names for the character include Smoe, Clem, Flywheel, Private Snoops, Overby, Eugene the Jeep, Scabooch, and Sapo.

According to Charles Panati, "The outrageousness of the graffiti was not so much what it said, but where it turned up." It is not known if there was an actual person named Kilroy who inspired the graffiti, although there have been claims over the years.

The fundamental theorem of software engineering (FTSE) is a term originated by Andrew Koenig to describe a remark by Butler Lampson attributed to the late David J. Wheeler:

"We can solve any problem by introducing an extra level of indirection."

The theorem does not describe an actual theorem that can be proven; rather, it is a general principle for managing complexity through abstraction.

The theorem is often expanded by the humorous clause "…except for the problem of too many levels of indirection," referring to the fact that too many abstractions may create intrinsic complexity issues of their own. For example, the use of protocol layering in computer networks, which today is ubiquitous, has been criticized in ways that are typical of more general disadvantages of abstraction. Here, the adding of extra levels of indirection may cause higher layers to duplicate the functionality of lower layers, leading to inefficiency, and functionality at one layer may need data present only at another layer, which fundamentally violates the goal of separation into different layers.

🔗 Physics

The Large Electron–Positron Collider (LEP) was one of the largest particle accelerators ever constructed.

It was built at CERN, a multi-national centre for research in nuclear and particle physics near Geneva, Switzerland. LEP collided electrons with positrons at energies that reached 209 GeV. It was a circular collider with a circumference of 27 kilometres built in a tunnel roughly 100 m (300 ft) underground and passing through Switzerland and France. LEP was used from 1989 until 2000. Around 2001 it was dismantled to make way for the Large Hadron Collider, which re-used the LEP tunnel. To date, LEP is the most powerful accelerator of leptons ever built.

The Sámi National Day is an ethnic national day for the Sámi (Saami) people that falls on February 6, the date when the first Sámi congress was held in 1917 in Trondheim, Norway. The congress was the first time that Norwegian and Swedish Sámi came together across national borders to work on finding solutions to common problems.

In 1992 at the 15th Sámi Conference in Helsinki, Finland, a resolution was passed that Sámi National Day should be celebrated on February 6 to commemorate the first Sámi congress in 1917, that Sami National Day is for all Sámi, regardless of where they live, and on that day the Sámi flag should be flown and the Sámi anthem sung in the local Sámi language. The first time Sami National Day was celebrated was in 1993, when the International Year of Indigenous People was proclaimed open in Jokkmokk, Sweden by the United Nations.

Since then, celebrating the day has become increasingly popular. In Norway, it is compulsory for municipal administrative buildings to fly the Norwegian flag, and optionally also the Sami flag, on February 6. Particularly notable is the celebration in Norway's capital Oslo, where the bells in the highest tower of Oslo City Hall play the Sami national anthem as the flags are raised. Some larger places have taken to arranging festivities in the week around the Sami National Day. The National Day has been included in the almanacs published by the University of Helsinki since 2004. The Norwegian, Swedish, and Finnish authorities recommend general flagging on the day.

By coincidence, February 6 was also the date representatives of the Sámi of the Kola Peninsula gathered annually to meet with Russian bureaucrats to debate and decide on issues of relevance to them. This assembly, called the Kola Sobbar, has been dubbed the "first Sámi Parliament" by the researcher Johan Albert Kalstad. However, the founding of the Kola Sobbar did not influence the choice of the date for Sámi People's Day, as the assembly existed only during the late 1800s and was largely forgotten until the early 2000s.

The British Amateur Television Club (BATC) is the world's largest television technology club; it has members in the UK and all around the world and is a non-profit making club run by an elected committee of volunteers for the benefit of its members. Membership is open to all who are interested in television, amateur or professional, indeed the club has many members who work for major broadcasting companies.

🔗 Mathematics

The potato paradox is a mathematical calculation that has a counter-intuitive result. The Universal Book of Mathematics states the problem as follows:

Fred brings home 100 kg of potatoes, which (being purely mathematical potatoes) consist of 99% water. He then leaves them outside overnight so that they consist of 98% water. What is their new weight? The surprising answer is 50 kg.

In Quine's classification of paradoxes, the potato paradox is a veridical paradox.

🔗 Military history 🔗 Futures studies 🔗 Military history/Cold War 🔗 Cold War

World War III or the Third World War, often abbreviated as WWIII or WW3, are names given to a hypothetical third worldwide large-scale military conflict after World War I and World War II. The term has been in use since at least as early as 1941. Some apply it loosely to limited or more minor conflicts such as the Cold War or the war on terror. In contrast, others assume that such a conflict would surpass prior world wars in both scope and destructive impact.

Due to the development and use of nuclear weapons near the end of World War II and their subsequent acquisition and deployment by many countries, the potential risk of a nuclear apocalypse causing widespread destruction of Earth's civilization and life is a common theme in speculations about a Third World War. Another primary concern is that biological warfare could cause many casualties. It could happen intentionally or inadvertently, by an accidental release of a biological agent, the unexpected mutation of an agent, or its adaptation to other species after use. Large-scale apocalyptic events like these, caused by advanced technology used for destruction, could render Earth's surface uninhabitable.

Before the beginning of World War II in 1939, World War I (1914–1918) was believed to have been "the war to end [all] wars." It was popularly believed that never again could there possibly be a global conflict of such magnitude. During the interwar period, World War I was typically referred to simply as "The Great War". The outbreak of World War II disproved the hope that humanity might have already "outgrown" the need for such widespread global wars.

With the advent of the Cold War in 1945 and with the spread of nuclear weapons technology to the Soviet Union, the possibility of a third global conflict became more plausible. During the Cold War years, the possibility of a Third World War was anticipated and planned for by military and civil authorities in many countries. Scenarios ranged from conventional warfare to limited or total nuclear warfare. At the height of the Cold War, the doctrine of mutually assured destruction (MAD), which determined an all-out nuclear confrontation would destroy all of the states involved in the conflict, had been developed. The absolute potential destruction of the human race may have contributed to the ability of both American and Soviet leaders to avoid such a scenario.

Woo! Yeah! is a drum break that includes James Brown's ("Woo!") and Bobby Byrd's ("Yeah!") voices which has been widely sampled in popular music, often in the form of a loop. The drum break was performed by John "Jabo" Starks. It originates from the 1972 Lyn Collins recording "Think (About It)", a song written and produced by Brown, and is just one of a few other frequently used breaks contained in the recording, often collectively known as the Think Break.

🔗 Olympics 🔗 Lists 🔗 Arts

There were 146 medalists in the art competitions that were part of the Olympic Games from 1912 until 1948. These art competitions were considered an integral part of the movement by International Olympic Committee (IOC) founder Pierre de Coubertin and necessary to recapture the complete essence of the Ancient Olympic Games. Their absence before the 1912 Summer Olympics, according to journalism professor Richard Stanton, stems from Coubertin "not wanting to fragment the focus of his new and fragile movement". Art competitions were originally planned for inclusion in the 1908 Summer Olympics but were delayed after that edition's change in venue from Rome to London following the 1906 eruption of Mount Vesuvius. By the 1924 Summer Olympics they had grown to be considered internationally relevant and potentially "a milestone in advancing public awareness of art as a whole".

During their first three appearances, the art competitions were grouped into five broad categories: architecture, literature, music, painting, and sculpture. The Dutch Organizing Committee for the 1928 Summer Olympics split these into subcategories in the hopes of increasing participation. Although it was a successful strategy, the 1932 Summer Olympics eliminated several of these subcategories, which led to fewer entries in the broader categories. For the 1936 Summer Olympics, the German government proposed the addition of a film contest to the program, which was rejected.

Following a final appearance at the 1948 Summer Olympics, art competitions were removed from the Olympic program. Planners of the 1952 Summer Olympics opposed their inclusion on logistical grounds, claiming that the lack of an international association for the event meant that the entire onus of facilitation was placed on the local organizing committee. Concerns were also raised about the professionalism of the event, since only amateurs were allowed to participate in the sporting tournaments, and the growing commercialization of the competitions, as artists had been permitted to sell their submissions during the course of the Games since 1928. In 1952 an art festival and exhibition was held concurrent with the Games, a tradition that has been maintained in all subsequent Summer Olympics.

The IOC does not track medalists in Olympic art competitions in its database and thus the prize winners are only officially recorded in the original Olympic reports. Judges were not required to distribute first, second, and third place awards for every category, and thus certain events lack medalists in these placements. Since participants were allowed multiple submissions, it was also possible for artists to win more than one in a single event, as Alex Diggelmann of Switzerland did in the graphic arts category of the 1948 edition. Diggelmann is tied with Denmark's Josef Petersen, who won second prize three times in literature, for the number of medals captured in the art competitions. Luxembourg's Jean Jacoby is the only individual to win two gold medals, doing so in painting in 1924 and 1928. Of the 146 medalists, 11 were women and only Finnish author Aale Tynni was awarded gold. Germany was the most successful nation, with eight gold, seven silver, and nine bronze medals, although one was won by Coubertin himself, a Frenchman. He submitted his poem Ode to Sport under the pseudonyms Georges Hohrod and Martin Eschbach, as if it were a joint-entry, and won first prize in the 1912 literature category. The original report credits this medal to Germany. Two individuals, Walter W. Winans and Alfréd Hajós, won medals in both athletic and art competitions.
