input: Please answer the following: A friend asked me to answer this question: What were the full names of the two people who calculated the critical mass of uranium?, using the article: At Birmingham, Oliphant's team had reached a different conclusion. Oliphant had delegated the task to two German refugee scientists, Rudolf Peierls and Otto Frisch, who could not work on Oliphant's radar project because they were enemy aliens and therefore lacked the necessary security clearance. Francis Perrin had calculated the critical mass of uranium to be about 40 tonnes (39 long tons; 44 short tons). He reckoned that if a neutron reflector were placed around it, this might be reduced to 12 tonnes (12 long tons; 13 short tons). Peierls attempted to simplify the problem by using the fast neutrons produced by fission, thus omitting consideration of moderator. He too calculated the critical mass of a sphere of uranium in a theoretical paper written in 1939 to be "of the order of tons".Peierls knew the importance of the size of the critical mass that would allow a chain reaction to take place and its practical significance. In the interior of a critical mass sphere, neutrons are spontaneously produced by the fissionable material. A very small portion of these neutrons are colliding with other nuclei, while a larger portion of the neutrons are escaping through the surface of the sphere. Peierls calculated the equilibrium of the system, where the number of neutrons being produced equalled the number escaping.Niels Bohr had theorised that the rare uranium-235 isotope, which makes up only about 0.7% of natural uranium, was primarily responsible for fission with fast neutrons, although this was not yet universally accepted. Frisch and Peierls were thus able to revise their initial estimate of critical mass needed for nuclear fission in uranium to be substantially less than previously assumed. They estimated a metallic sphere of uranium-235 with a radius of 2.1 centimetres (0.83 in) could suffice. This amount represented approximately 1 kilogram (2.2 lb) of uranium-235. These results led to the Frisch–Peierls memorandum, which was the initial step in the development of the nuclear arms programme in Britain. This..., what would be the answer ?

input: Please answer the following: A friend asked me to answer this question: Whose records were played by the Japanese over the loudspeakers to make US soldiers homesick?, using the article: While Stafford was still working for Dorsey, Johnny Mercer told her, "Some day I'm going to have my own record company, and you're going to record for me." She subsequently became the first solo artist signed to Capitol after leaving the Pied Pipers in 1944. A key figure in helping Stafford to develop her solo career was Mike Nidorf, an agent who first heard her as a member of the Pied Pipers while he was serving as a Captain with the United States Army. Having previously discovered artists such as Glenn Miller, Artie Shaw, and Woody Herman, Nidorf was impressed by Stafford's voice, and contacted her when he was demobilized in 1944. After she agreed to let him represent her, he encouraged her to reduce her weight and arranged a string of engagements that raised her profile, and confidence.The success of Stafford's solo career led to a demand for personal appearances, and from February 1945 she embarked on a six-month residency at New York's La Martinique nightclub. Her performance was well-received—an article in the July 1945 edition of Band Leaders magazine described it as "sensational"—but Stafford did not enjoy singing before live audiences, and it was the only nightclub venue she ever played. Speaking about her discomfort with live performances, Stafford told a 1996 interview with The New Yorker's Nancy Franklin, "I'm basically a singer, period, and I think I'm really lousy up in front of an audience—it's just not me."Stafford's tenure with the United Service Organizations (USO) during World War II—which often saw her perform for soldiers stationed in the U.S.—led to her acquiring the nickname "G.I. Jo". On returning from the Pacific theater, a veteran told Stafford that the Japanese would play her records on loudspeakers in an attempt to make the U.S. troops homesick enough to surrender. She replied personally to all the letters she received from servicemen. Stafford was a favorite of many servicemen during both World War II and the Korean War; her recordings received extensive airplay on the American..., what would be the answer ?

input: Please answer the following: A friend asked me to answer this question: What are the first names of the three individuals who, in the original line-up, contributed to the band's lyrics?, using the article: Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist and bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt. Hanneman and drummers Dave Lombardo and Jon Dette are former members of the band. In the original line-up, King, Hanneman and Araya contributed to the band's lyrics, and all of the band's music was written by King and  Hanneman. The band's lyrics and album art, which cover topics such as murder, serial killers, necrophilia, torture, genocide, human experimentation, Satanism, hate crimes, terrorism, religion, antireligion, Nazism and war, have generated album bans, delays, lawsuits and criticism from religious groups and factions of the general public. However, its music has been highly influential, often being cited by many bands as an influence musically, visually and lyrically; the band's third album, Reign in Blood (1986), was described as one of the heaviest and most influential thrash metal albums. Slayer has released twelve studio albums, two live albums, a box set, six music videos, two extended plays and a cover album. Four of the band's studio albums have received gold certification in the United States. The band has received five Grammy Award nominations, winning one in 2007 for the song "Eyes of the Insane" and one in 2008 for the song "Final Six", both of which were from the album Christ Illusion (2006). Between 1991 and 2013, the band sold five million albums in the United States. After 37 years of recording and performing, Slayer announced in January 2018 that they would embark on their final world tour, which began that May and is estimated to wrap up in 2019 or 2020., what would be the answer ?
