[Q]: What is the name of the person that the man who learned about implosion took that information to? Answer the above question based on the context below: The breakthrough with plutonium was by Bretscher and Norman Feather at the Cavendish Laboratory. They realised that a slow neutron reactor fuelled with uranium would theoretically produce substantial amounts of plutonium-239 as a by-product. This is because uranium-238 absorbs slow neutrons and forms a short-lived new isotope, uranium-239. The new isotope's nucleus rapidly emits an electron through beta decay producing a new element with an atomic mass of 239 and an atomic number of 93. This element's nucleus also emits an electron and becomes a new element with an atomic number 94 and a much greater half-life. Bretscher and Feather showed theoretically feasible grounds that element 94 would be fissilereadily fissioned by both slow and fast neutrons, with the added advantage of being different from uranium, and therefore could be chemically separated from it. Bretscher even devised a chemical method to separate.This new development was also confirmed in independent work by Edwin M. McMillan and Philip Abelson at Berkeley Radiation Laboratory also in 1940. Nicholas Kemmer of the Cambridge team proposed the names neptunium for the new element 93 and plutonium for 94 by analogy with the outer planets Neptune and Pluto beyond Uranus (uranium being element 92). The Americans fortuitously suggested the same names. The production and identification of the first sample of plutonium in 1941 is generally credited to Glenn Seaborg, using a cyclotron rather than a reactor at the University of California. In 1941, neither team knew of the existence of the other.Chadwick voiced concerns about the need for such pure plutonium to make a feasible bomb. He also suspected that the gun method of detonation for a plutonium bomb would lead to premature detonations due to impurities. After Chadwick met Robert Oppenheimer at the Los Alamos Laboratory in 1943, he learned of a proposed bomb design which they were calling an implosion. The sub-critical mass of plutonium was supposed to be surrounded by explosives that were arranged to...

[Q]: Where did Moore visit during his six-month traveling scholarship? Answer the above question based on the context below: After the Great War, Moore received an ex-serviceman's grant to continue his education and in 1919 he became a student at the Leeds School of Art (now Leeds College of Art), which set up a sculpture studio especially for him. At the college, he met Barbara Hepworth, a fellow student who would also become a well-known British sculptor, and began a friendship and gentle professional rivalry that lasted for many years. In Leeds, Moore also had access to the modernist works in the collection of Sir Michael Sadler, the University Vice-Chancellor, which had a pronounced effect on his development. In 1921, Moore won a scholarship to study at the Royal College of Art in London, along with Hepworth and other Yorkshire contemporaries. While in London, Moore extended his knowledge of primitive art and sculpture, studying the ethnographic collections at the Victoria and Albert Museum and the British Museum. The student sculptures of both Moore and Hepworth followed the standard romantic Victorian style, and included natural forms, landscapes and figurative modelling of animals. Moore later became uncomfortable with classically derived ideals; his later familiarity with primitivism and the influence of sculptors such as Constantin Brancusi, Jacob Epstein, Henri Gaudier-Brzeska and Frank Dobson led him to the method of direct carving, in which imperfections in the material and marks left by tools became part of the finished sculpture. Having adopted this technique, Moore was in conflict with academic tutors who did not appreciate such a modern approach. During one exercise set by Derwent Wood (the professor of sculpture at the Royal College), Moore was asked to reproduce a marble relief of Domenico Rosselli's The Virgin and Child by first modelling the relief in plaster, then reproducing it in marble using the mechanical aid known as a "pointing machine", a technique called "pointing". Instead, he carved the relief directly, even marking the surface to simulate the prick marks that would have been left by the pointing...

[Q]: What were the names of the two towns that have become known as Weymouth? Answer the above question based on the context below: Weymouth originated as a settlement on a constricted site to the south and west of Weymouth Harbour, an outlying part of Wyke Regis. The town developed from the mid 12th century onwards, but was not noted until the 13th century. By 1252 it was established as a seaport and became a chartered borough. Melcombe Regis developed separately on the peninsula to the north of the harbour; it was mentioned as a licensed wool port in 1310. French raiders found the port so accessible that in 1433 the staple was transferred to Poole. Melcombe Regis is thought to be the first port at which the Black Death came into England in June 1348, possibly either aboard a spice ship or an army ship. In their early history Weymouth and Melcombe Regis were rivals for trade and industry, but the towns were united in an Act of Parliament in 1571 to form a double borough. Both towns have become known as Weymouth, despite Melcombe Regis being the main centre. The villages of Upwey, Broadwey, Preston, Wyke Regis, Chickerell, Southill, Radipole and Littlemoor have become part of the built-up area. King Henry VIII had two Device Forts built to protect the south Dorset coast from invasion in the 1530s: Sandsfoot Castle in Wyke Regis and Portland Castle in Castletown. Parts of Sandsfoot have fallen into the sea due to coastal erosion. During the English Civil War, around 250 people were killed in the local Crabchurch Conspiracy in February 1645. In 1635, on board the ship Charity, around 100 emigrants from the town crossed the Atlantic Ocean and settled in Weymouth, Massachusetts. More townspeople emigrated to the Americas to bolster the population of Weymouth, Nova Scotia and Salem, Massachusetts; then called Naumking. There are memorials to this on the side of Weymouth Harbour and near to Weymouth Pavilion and Weymouth Sea Life Tower. The architect Sir Christopher Wren was the Member of Parliament for Weymouth in 1702, and controlled nearby Portland's quarries from 1675 to 1717. When he designed St Paul's Cathedral, Wren had it built out of...
