Louis Aimé Augustin Le Prince (28 August 1841 – disappeared 16 September 1890, declared dead 16 September 1897) was a French artist and the inventor of an early motion-picture camera, possibly the first person to shoot a moving picture sequence using a single lens camera and a strip of (paper) film. He has been credited as the "Father of Cinematography", but his work did not influence the commercial development of cinema—owing at least in part to the great secrecy surrounding it.

A Frenchman who also worked in the United Kingdom and the United States, Le Prince's motion-picture experiments culminated in 1888 in Leeds, England. In October of that year, he filmed moving-picture sequences of family members in Roundhay Garden and his son playing the accordion, using his single-lens camera and Eastman's paper negative film. At some point in the following eighteen months he also made a film of Leeds Bridge. This work may have been slightly in advance of the inventions of contemporaneous moving-picture pioneers, such as the British inventors William Friese-Greene and Wordsworth Donisthorpe, and was years in advance of that of Auguste and Louis Lumière and William Kennedy Dickson (who did the moving image work for Thomas Edison).

Le Prince was never able to perform a planned public demonstration of his camera in the US because he mysteriously vanished; he was last known to be boarding a train on 16 September 1890. Multiple conspiracy theories have emerged about the reason for his disappearance, including: a murder set up by Edison, secret homosexuality, disappearance in order to start a new life, suicide because of heavy debts and failing experiments, and a murder by his brother over their mother's will. No conclusive evidence exists for any of these theories. In 2004, a police archive in Paris was found to contain a photograph of a drowned man bearing a strong resemblance to Le Prince who was discovered in the Seine just after the time of his disappearance, but it has been claimed that the body was too short to be Le Prince.

In early 1890, Edison workers had begun experimenting with using a strip of celluloid film to capture moving images. The first public results of these experiments were shown in May 1891. However, Le Prince's widow and son Adolphe were keen to advance Louis's cause as the inventor of cinematography. In 1898, Adolphe appeared as a witness for the defence in a court case brought by Edison against the American Mutoscope Company. This suit claimed that Edison was the first and sole inventor of cinematography, and thus entitled to royalties for the use of the process. Adolphe was involved in the case but was not allowed to present his father's two cameras as evidence, although films shot with cameras built according to his father's patent were presented. Eventually the court ruled in favour of Edison. A year later that ruling was overturned, but Edison then reissued his patents and succeeded in controlling the US film industry for many years.

🔗 Board and table games

Uckers is a two- or four-player board game traditionally played in the Royal Navy and has spread to many of the other arms of the UK Armed Forces as well as to, mainly Commonwealth Forces. It can now be found also in the Royal Marines, Army Air Corps, Royal Canadian Navy, Royal New Zealand Navy, Royal Australian Navy, Royal Australian Air Force (RAAF), Royal Dutch Navy, and the Royal Air Force (RAF). It is believed to originate in the 18th/19th centuries from the Indian game Pachisi, although the first reference to it in print does not appear until 1946. It is mentioned in a diary by EJF Records (served 1928-1950) in 1937 as Huckers. Uckers is generally played using the rules stated below, but these will vary from one branch of the Royal Navy to another, most famously with the WAFU Rules of the Fleet Air Arm. Where those branches of the RN have worked with the other Armed Forces usually has dictated what rules the new playing Service use; why fellow aviators tend to play under WAFU Rules for example.

It is also played in units of the Army Air Corps (United Kingdom) where it was introduced by aircraft technicians on loan from the Fleet Air Arm in the late 1950s/early 1960s. Uckers boards can now also be found in most RAF Squadron crewroom, where the game has caught on, especially with the Aircraft Technicians. Most RAAF crew rooms feature uckers boards also. In addition to the units services, units mentioned, uckers was also played by units in the Royal Artillery, particularly meteorologists and LifeFlight Toowoomba Rescue Helicopter crews aka Rescue 588. The current and now 7-time world champion is Queenslander Mark Arthur. In the UK the Pusser's Rum World 'Uckers championships have been played for the last 5 years at various ROYAL NAVAL MUSEUMS, the most being notable being 2017 when the final was played on Nelson's Flagship HMS VICTORY and was won by the'timber shifters' Wally Blagden and David Clark both ex RN. The next Pusser's Rum WORLD 'uckers' championships are being played in the Explosion Museum Gosport 26 October 2019. Wally andDavid are also current HMS GANGES Champions won in April 2019 Update Wally Blagden and Dave Clark the 'Timbershifters' have won the 2019 Championships. Knock knock. The chicken

It is similar to the board game Ludo and is based on the same principles; getting four player pieces around the board before the opposition. The whole point of Uckers is to get all player pieces home before the opponent does. However, greater glory is attached to achieving all pieces home without the opponent getting any home at all—this is known as an 8 piecer. The ultimate win is when the player gets all their pieces home and the opponent has all their pieces still in the base—this is called an 8 piece in harbour, or an eight-piece dicking and merits the unfortunate player's name to be recorded on the reverse of the board.

PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz, or 716 times per second. This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004 and confirmed on January 8, 2005.

If the neutron star is assumed to contain less than two times the mass of the Sun, within the typical range of neutron stars, its radius is constrained to be less than 16 km. At its equator it is spinning at approximately 24% of the speed of light, or over 70,000 km per second.

The pulsar is located in a globular cluster of stars called Terzan 5, located approximately 18,000 light-years from Earth in the constellation Sagittarius. It is part of a binary system and undergoes regular eclipses with an eclipse magnitude of about 40%. Its orbit is highly circular with a 26-hour period. The other object is at least 0.14 solar masses, with a radius of 5–6 solar radii. Hessels et al. state that the companion may be a "bloated main-sequence star, possibly still filling its Roche Lobe". Hessels et al. go on to speculate that gravitational radiation from the pulsar might be detectable by LIGO.

In C is a musical piece composed by Terry Riley in 1964 for an indefinite number of performers. He suggests "a group of about 35 is desired if possible but smaller or larger groups will work". A series of short melodic fragments that can be repeated at the discretion of musicians, In C is often cited as the first minimalist composition to make a significant impact on the public consciousness.

The piece was first performed by Steve Reich, Jon Gibson, Pauline Oliveros, Stuart Dempster, Morton Subotnick and others at the San Francisco Tape Music Center. It received its first recorded release in 1968 on CBS Records. Subsequent performances have been recorded many times since.

In 2022, the 1968 LP recording of In C was selected by the Library of Congress for preservation in the United States National Recording Registry as being "culturally, historically, or aesthetically significant.".

The Emu War, also known as the Great Emu War, was a nuisance wildlife management military operation undertaken in Australia over the latter part of 1932 to address public concern over the number of emus said to be running amok in the Campion district of Western Australia. The unsuccessful attempts to curb the population of emus, a large flightless bird indigenous to Australia, employed soldiers armed with Lewis guns—leading the media to adopt the name "Emu War" when referring to the incident. While a number of the birds were killed, the emu population persisted and continued to cause crop destruction.

In the field of psychology, the Dunning–Kruger effect is a cognitive bias in which people assess their cognitive ability as greater than it is. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence.

As described by social psychologists David Dunning and Justin Kruger, the cognitive bias of illusory superiority results from an internal illusion in people of low ability and from an external misperception in people of high ability; that is, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."

Stratton Oakmont, Inc. v. Prodigy Services Co., 23 Media L. Rep. 1794 (N.Y. Sup. Ct. 1995), is a 1995 U.S. New York Supreme Court decision holding that online service providers could be held liable for the speech of their users. The ruling caused controversy among early supporters of the Internet, including some lawmakers, leading to the passage of Section 230 of the Communications Decency Act in 1996.

In pipeline transportation, pigging is the practice of using devices known as pigs or scrapers to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline. These devices are known as pigs because they scrape or clean just like a normal pig.

These operations include but are not limited to cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a "pig launcher" (or "launching station") — an oversized section in the pipeline, reducing to the normal diameter. The launching station is then closed and the pressure-driven flow of the product in the pipeline is used to push the pig along down the pipe until it reaches the receiving trap — the "pig catcher" (or "receiving station").

In political jargon, a useful idiot is a derogatory term for a person perceived as propagandizing for a cause without fully comprehending the cause's goals, and who is cynically used by the cause's leaders. The term was originally used during the Cold War to describe non-communists regarded as susceptible to communist propaganda and manipulation. The term has often been attributed to Vladimir Lenin, but this attribution is unsubstantiated.
