Input: Read this: The spectrum emitted by a blackbody radiator at temperatures of incandescent bulbs does not match the sensitivity characteristics of the human eye; the light emitted does not appear white, and most is not in the range of wavelengths at which the eye is most sensitive. Tungsten filaments radiate mostly infrared radiation at temperatures where they remain solid – below 3,695 K (3,422 °C; 6,191 °F). Donald L. Klipstein explains it this way: "An ideal thermal radiator produces visible light most efficiently at temperatures around 6,300 °C (6,600 K; 11,400 °F). Even at this high temperature, a lot of the radiation is either infrared or ultraviolet, and the theoretical luminous efficacy (LER) is 95 lumens per watt." No known material can be used as a filament at this ideal temperature, which is hotter than the sun's surface. An upper limit for incandescent lamp luminous efficacy (LER) is around 52 lumens per watt, the theoretical value emitted by tungsten at its melting point.
Question: What is not infrared or ultraviolet?

Output: unanswerable


QUES: The Pacific War saw the Allied powers pitted against the Empire of Japan, the latter briefly aided by Thailand and to a much lesser extent by its Axis allies, Germany and Italy. The war culminated in the atomic bombings of Hiroshima and Nagasaki, and other large aerial bomb attacks by the United States Army Air Forces, accompanied by the Soviet invasion of Manchuria on 8 August 1945, resulting in the Japanese announcement of intent to surrender on 15 August 1945. The formal and official surrender of Japan took place aboard the battleship USS Missouri in Tokyo Bay on 2 September 1945. Following its defeat, Japan's Shinto Emperor stepped down as the divine leader through the Shinto Directive, because the Allied Powers believed this was the major political cause of Japan's military aggression and deconstruction process soon took place to install a new liberal-democratic constitution to the Japanese public as the current Constitution of Japan.

When did the Soviet Union invade Manchuria?
What is the answer?
ANS: 8 August 1945


QUES: The Chalukya Empire (Kannada: ಚಾಲುಕ್ಯರು [tʃaːɭukjə]) was an Indian royal dynasty that ruled large parts of southern and central India between the 6th and the 12th centuries. During this period, they ruled as three related yet individual dynasties. The earliest dynasty, known as the "Badami Chalukyas", ruled from Vatapi (modern Badami) from the middle of the 6th century. The Badami Chalukyas began to assert their independence at the decline of the Kadamba kingdom of Banavasi and rapidly rose to prominence during the reign of Pulakeshin II. The rule of the Chalukyas marks an important milestone in the history of South India and a golden age in the history of Karnataka. The political atmosphere in South India shifted from smaller kingdoms to large empires with the ascendancy of Badami Chalukyas. A Southern India-based kingdom took control and consolidated the entire region between the Kaveri and the Narmada rivers. The rise of this empire saw the birth of efficient administration, overseas trade and commerce and the development of new style of architecture called "Chalukyan architecture". The Chalukya dynasty ruled parts of southern and central India from Badami in Karnataka between 550 and 750, and then again from Kalyani between 970 and 1190.
When did the Chalukyans rule from Badami?

ANS: 550 and 750


Comcast is sometimes described as a family business. Brian L. Roberts, Chairman, President, and CEO of Comcast, is son of co-founder Ralph Roberts. Roberts owns or controls just over 1% of all Comcast shares but all of the Class B supervoting shares, which gives him an "undilutable 33% voting power over the company". Legal expert Susan P. Crawford has said this gives him "effective control over its [Comcast's] every step". In 2010, he was one of the highest-paid executives in the United States, with total compensation of about $31 million.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is Brian L. Robert's son?
Ah, so.. unanswerable


Question: Von Neumann's principal contribution to the atomic bomb was in the concept and design of the explosive lenses needed to compress the plutonium core of the Fat Man weapon that was later dropped on Nagasaki. While von Neumann did not originate the "implosion" concept, he was one of its most persistent proponents, encouraging its continued development against the instincts of many of his colleagues, who felt such a design to be unworkable. He also eventually came up with the idea of using more powerful shaped charges and less fissionable material to greatly increase the speed of "assembly".
Try to answer this question if possible: Did von Nemann think that the atomic bomb design was not workable?
Answer: he was one of its most persistent proponents, encouraging its continued development


Problem: Winners receive the FA Cup trophy, of which there have been two designs and five actual cups; the latest is a 2014 replica of the second design, introduced in 1911. Winners also qualify for European football and a place in the FA Community Shield match. Arsenal are the current holders, having beaten Aston Villa 4–0 in the 2015 final to win the cup for the second year in a row. It was their 12th FA Cup title overall, making Arsenal the FA Cup's most successful club ahead of Manchester United on 11.
How many FA Cup Trophy replicas have been made?
