Tarsals are bones found in the feet. They are also known as ankle bones. There are seven of them in each foot. The seven tarsals are:
Georg Cantor
Georg Cantor (3 March 1845 - 6 January 1918) was an important German mathematician. He founded set theory and worked on transfinite numbers.
Cantor was born in St Petersburg, Russia. His father had a Jewish-Danish, his mother an Austrian background. His father was a Protestant. He was a rich merchant. His mother was a Roman Catholic. She was very artistic. When his father became ill in 1856 the family moved to Frankfurt. Georg went to private schools and then to gymnasien in Darmstadt and Wiesbaden. He soon showed that he was brilliant at maths. His father wanted him to be an engineer but Georg persuaded him to let him study mathematics. He spent a short time studying at the University of Zürich, but soon went to Berlin where he studied physics, philosophy and mathematics. He was very influenced by the teaching of Weierstrass, Kummer and Kronecker, who were later to become his enemies. He wrote a doctoral thesis in which he said that asking questions was more important than finding the answers. He was talking about a problem that Carl Friedrich Gauss had left unanswered.
Cantor taught for a time at a girls’ school in Berlin, then he became a lecturer in Halle where he remained for the rest of his life. He became full professor there in 1879. Cantor worked on the theory of numbers and then on trigonometric series, starting with ideas that had been developed by Bernhard Riemann on complex variables. He sent a paper on algebraic numbers to be published in Crelle's Journal, but Kronecker was against it. However, Dedekind supported Cantor, and eventually the article was published. This article showed that Cantor was a great mathematician.
When his father died in 1863 he had enough money to build a house for his wife and five children.
Cantor thought that infinite numbers really existed, and used ideas from ancient and medieval philosophy to prove his point. Kronecker disagreed with him. He thought that only integers existed. Kronecker said that “God made integers and all the rest is the work of man”. Kronecker stopped Cantor from being offered a professorship in Berlin, a position he ought to have had since he was one of the greatest mathematicians in the world. Cantor stayed at Halle and continued to work into his old age, although he often suffered from fits of depression. He often lost his temper, but he was also a very kind man. He always gave encouragement to young mathematicians with new ideas. He did not want them to suffer like he had because of older mathematicians who felt threatened by new ideas. A lot of Cantor’s work led eventually to what is called “new mathematics” in schools today.
Cantor died in a mental hospital in Halle on 6 January 1918.
Pay-per-view
Pay-per-view (often abbreviated PPV) is a way that people can pay to watch events on television in their homes. The event is shown at the same time to everyone ordering it. This is different than video on demand systems which lets people see the event at any time. Common events include movies, sporting events, and pornographic movies.
The first major pay-per-view event was on September 16, 1981. This event was Sugar Ray Leonard and Thomas Hearns for the Welterweight Championship. Viacom Cablevision in Nashville, Tennessee, was the first system to offer the event. Over fifty percent of its customers paid to see the fight. Viacom's Marketing Director, Pat Thompson, put together the fight. He later put together other PPV fights, wrestling matches, and even a Broadway play.
After leaving Viacom, Thompson became head of Sports View. He produced the first pay-per-view football game on October 16, 1983. Sports View was important in creating pay-per-view networks. It was a part of creating TigerVision for LSU, TideVision for Alabama, and UT Vol Seat for Tennessee. Sports View also produced the Ohio State-Michigan Football game on PPV in November of 1983.
In 1985, the first U.S. cable channels to show only pay-per-view, "Viewers Choice", "Cable Video Store", and "Request TV" began operation within days of each other. Viewers Choice was available to both home satellite dish and cable customers. Request TV was available to only cable viewers at first. Dish owners could not use it until the 1990s.
The term "pay-per-view" became more well known in the 1990s when companies like iN DEMAND, HBO, and Showtime started using it to show movies and other things. In Demand would show movies, concerts, and other events at prices between $3.99 to $49.99. HBO and Showtime would offer championship boxing, with prices between $14.99 to $54.99.
Pay-per-view is also a very important way for professional wrestling companies like World Wrestling Entertainment (WWE) , Total Nonstop Action Wrestling (TNA) , Ring of Honor (ROH) and Asistencia Asesoría y Administración to earn money.
The first pay-per-view system tested in the United states was the Zenith Phonevision system. In 1949, it used telephone lines to take and receive orders. The telephone lines were also used to descramble the signal on the television. Tests were run for 90 days in Chicago. In 1950, Skiatron tested its system on WOR in New York City. The system used IBM punch cards to descramble the signal. Both systems showed that they could be used but were not allowed to be used by the FCC.
One of the first pay-per-view systems on cable was the Optical Systems. It was first used in 1972 in San Diego. These early systems quickly went out of business, as the cable industry started using satellite technology. This caused systems, for example Home Box Office, which had people pay a constant amount of money each month to became popular.
Pay-per-view was first used in the United Kingdom with the use of satellite television and cable systems.
Pay-per-view was first used by Foxtel to home television in Australia and New Zealand in the early 2000s. Sky Pacific in Fiji and other Pacific Island Nations started using it in 2006.
Talus
The talus is the second largest of the seven tarsal (ankle) bones. It is next to the calcaneus and navicular bones.
Dhaka District
Dacca District () is a district in the centre of Bangladesh. The district is part of the Dhaka Division, more than half of the district is made up of Dacca - the capital of the district and of Bangladesh too.
Dhaka has a very old history, the city area of Dhaka was ruled by the Buddhist and Hindu kingdoms century.
After the Sena dynasty, Dhaka was ruled first by the Turkish and the Afghan governors from the Delhi Sultanate before the arrival of the Mughals in 1608.
During the rule of the Mughal the district was famous for its textile products - especially the Muslin. The Mughal governor Islam Khan was the first administrator of the city. Khan named the town "Jahangir Nagar" ("City of Jahangir") in honour of the Mughal emperor Jahangir, although this name was dropped soon after Jahangir's death.
The city grew in size quite a lot under Mughal general Shaista Khan. The city then measured 19 by 13 kilometres (12 by 8 mi), with almost a million people. The city then passed to the control of the British East India Company in 1765 after the Battle of Plassey. The number of people in the city fell very much as the prominence of Kolkata rose, but development eventually followed. A modern civic water supply system was introduced in 1874 and electricity supply launched in 1878. The Dhaka Cantonment was established near the city, serving as a base for British and Indian soldiers.
