The X-10 Graphite Reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile) and was the first reactor designed and built for continuous operation. Argonne National Laboratory's Experimental Breeder Reactor I, located at the Atomic Energy Commission's National Reactor Testing Station near Arco, Idaho, became the first nuclear reactor to create electricity on 20 December 1951. Initially, four 150-watt light bulbs were lit by the reactor, but improvements eventually enabled it to power the whole facility (later, the town of Arco became the first in the world to have all its electricity come from nuclear power generated by BORAX-III, another reactor designed and operated by Argonne National Laboratory). The world's first commercial scale nuclear power station, Obninsk in the Soviet Union, began generation with its reactor AM-1 on 27 June 1954. Other early nuclear power plants were Calder Hall in England, which began generation on 17 October 1956, and the Shippingport Atomic Power Station in Pennsylvania, which began on 26 May 1958. Nuclear power was used for the first time for propulsion by a submarine, the USS Nautilus, in 1954.
What was the world's last artificial nuclear reactor?
A: unanswerable

This situation prevailed until 1639, when most of Alsace was conquered by France so as to keep it out of the hands of the Spanish Habsburgs, who wanted a clear road to their valuable and rebellious possessions in the Spanish Netherlands. Beset by enemies and seeking to gain a free hand in Hungary, the Habsburgs sold their Sundgau territory (mostly in Upper Alsace) to France in 1646, which had occupied it, for the sum of 1.2 million Thalers. When hostilities were concluded in 1648 with the Treaty of Westphalia, most of Alsace was recognized as part of France, although some towns remained independent. The treaty stipulations regarding Alsace were complex; although the French king gained sovereignty, existing rights and customs of the inhabitants were largely preserved. France continued to maintain its customs border along the Vosges mountains where it had been, leaving Alsace more economically oriented to neighbouring German-speaking lands. The German language remained in use in local administration, in schools, and at the (Lutheran) University of Strasbourg, which continued to draw students from other German-speaking lands. The 1685 Edict of Fontainebleau, by which the French king ordered the suppression of French Protestantism, was not applied in Alsace. France did endeavour to promote Catholicism; Strasbourg Cathedral, for example, which had been Lutheran from 1524 to 1681, was returned to the Catholic Church. However, compared to the rest of France, Alsace enjoyed a climate of religious tolerance.
How much did France pay for Sundgau?
A: 1.2 million Thalers

Pioneer Electronics later purchased the majority stake in the format and marketed it as both LaserVision (format name) and LaserDisc (brand name) in 1980, with some releases unofficially referring to the medium as "Laser Videodisc". Philips produced the players while MCA produced the discs. The Philips-MCA cooperation was not successful, and discontinued after a few years. Several of the scientists responsible for the early research (Richard Wilkinson, Ray Dakin and John Winslow) founded Optical Disc Corporation (now ODC Nimbus).
Who were the scientists that worked on the early research for Laserdiscs?
A: Richard Wilkinson, Ray Dakin and John Winslow

In 1821, Alexis Bouvard published astronomical tables of the orbit of Neptune's neighbour Uranus. Subsequent observations revealed substantial deviations from the tables, leading Bouvard to hypothesise that an unknown body was perturbing the orbit through gravitational interaction. In 1843, John Couch Adams began work on the orbit of Uranus using the data he had. Via Cambridge Observatory director James Challis, he requested extra data from Sir George Airy, the Astronomer Royal, who supplied it in February 1844. Adams continued to work in 184546 and produced several different estimates of a new planet.
What did the extra data John Couch Adams received produce?
A:
several different estimates of a new planet
