question:
The Great Fire of London was a major conflagration that swept through the central parts of the English city of London from Sunday, 2 September to Wednesday, 5 September 1666. The fire gutted the medieval City of London inside the old Roman city wall. It threatened but did not reach the aristocratic district of Westminster, Charles II's Palace of Whitehall, and most of the suburban slums. It consumed 13,200 houses, 87 parish churches, St Paul's Cathedral, and most of the buildings of the City authorities. It is estimated to have destroyed the homes of 70,000 of the City's 80,000 inhabitants.
answer:
where did the great fire of london finish


question:
Following a shuffle of the cards, play begins with each player being dealt two cards face down, with the player in the small blind receiving the first card and the player in the button seat receiving the last card dealt. (As in most poker games, the deck is a standard 52-card deck containing no jokers.) These cards are the players' hole or pocket cards. These are the only cards each player will receive individually, and they will only (possibly) be revealed at the showdown, making Texas hold' em a closed poker game.
answer:
how many deck of cards for texas holdem


question:
Ancient civilizations required fairly accurate computed values for π for practical reasons, including the Egyptians and Babylonians. Around 250 BC the Greek mathematician Archimedes created an algorithm for calculating it. It was approximated to seven digits, using geometrical techniques, in Chinese mathematics, and to about five digits in Indian mathematics in the 5th century AD. The historically first exact formula for π, based on infinite series, was not available until a millennium later, when in the 14th century the Madhava -- Leibniz series was discovered in Indian mathematics. In the 20th and 21st centuries, mathematicians and computer scientists discovered new approaches that, when combined with increasing computational power, extended the decimal representation of π to many trillions of digits after the decimal point. Practically all scientific applications require no more than a few hundred digits of π, and many substantially fewer, so the primary motivation for these computations is the quest to find more efficient algorithms for calculating lengthy numeric series, as well as the desire to break records. The extensive calculations involved have also been used to test supercomputers and high-precision multiplication algorithms.
answer:

who was the person known to find the first calculation of pi when was it
