Here is a question about this article: Infrared is used in night vision equipment when there is insufficient visible light to see. Night vision devices operate through a process involving the conversion of ambient light photons into electrons that are then amplified by a chemical and electrical process and then converted back into visible light. Infrared light sources can be used to augment the available ambient light for conversion by night vision devices, increasing in-the-dark visibility without actually using a visible light source.
What is the answer to this question: What do night vision devices convert ambient light photons into?
****
So... electrons

The problem: Answer a question about this article:
The King presides over a period of misrule in which conventional social rules may be broken and reckless behavior is encouraged. Festivities are held in the open air, beginning with a cercavila, a ritual procession throughout the town to call everyone to attend. Rues of masked revelers dance alongside. On Thursday Dijous Gras (Fat Thursday) is celebrated, also called 'omelette day' (el dia de la truita), coques (de llardons, butifarra d'ou, butifarra) and omelettes are eaten. The festivities end on Ash Wednesday with elaborate funeral rituals marking the death of King Carnival, who is typically burned on a pyre in what is called the burial of the sardine (enterrament de la sardina), or, in Vilanova, as l'enterro.
Who is typically burned on a pyre?
****
The answer: King Carnival

Problem: Please answer a question about the following article about Tennessee:
Tennessee has played a critical role in the development of many forms of American popular music, including rock and roll, blues, country, and rockabilly.[not verified in body] Beale Street in Memphis is considered by many to be the birthplace of the blues, with musicians such as W.C. Handy performing in its clubs as early as 1909.[not verified in body] Memphis is also home to Sun Records, where musicians such as Elvis Presley, Johnny Cash, Carl Perkins, Jerry Lee Lewis, Roy Orbison, and Charlie Rich began their recording careers, and where rock and roll took shape in the 1950s.[not verified in body] The 1927 Victor recording sessions in Bristol generally mark the beginning of the country music genre and the rise of the Grand Ole Opry in the 1930s helped make Nashville the center of the country music recording industry.[not verified in body] Three brick-and-mortar museums recognize Tennessee's role in nurturing various forms of popular music: the Memphis Rock N' Soul Museum, the Country Music Hall of Fame and Museum in Nashville, and the International Rock-A-Billy Museum in Jackson. Moreover, the Rockabilly Hall of Fame, an online site recognizing the development of rockabilly in which Tennessee played a crucial role, is based in Nashville.[not verified in body]
What Tennessee recording company first promoted Elvis Presley?
A: Sun Records

Question: Read this and answer the question

Tibetan music often involves chanting in Tibetan or Sanskrit, as an integral part of the religion. These chants are complex, often recitations of sacred texts or in celebration of various festivals. Yang chanting, performed without metrical timing, is accompanied by resonant drums and low, sustained syllables. Other styles include those unique to the various schools of Tibetan Buddhism, such as the classical music of the popular Gelugpa school, and the romantic music of the Nyingmapa, Sakyapa and Kagyupa schools.

What type of music comes from the popular Gelugpa school?
Answer: classical

Problem: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
What did the light quantum behave the same as in laboratory experiments?
The answer is the following: neutral particle

Input: Article: With the help of Charles Stearn, an expert on vacuum pumps, in 1878, Swan developed a method of processing that avoided the early bulb blackening. This received a British Patent in 1880.[dubious discuss] On 18 December 1878, a lamp using a slender carbon rod was shown at a meeting of the Newcastle Chemical Society, and Swan gave a working demonstration at their meeting on 17 January 1879. It was also shown to 700 who attended a meeting of the Literary and Philosophical Society of Newcastle upon Tyne on 3 February 1879. These lamps used a carbon rod from an arc lamp rather than a slender filament. Thus they had low resistance and required very large conductors to supply the necessary current, so they were not commercially practical, although they did furnish a demonstration of the possibilities of incandescent lighting with relatively high vacuum, a carbon conductor, and platinum lead-in wires. Besides requiring too much current for a central station electric system to be practical, they had a very short lifetime. Swan turned his attention to producing a better carbon filament and the means of attaching its ends. He devised a method of treating cotton to produce 'parchmentised thread' and obtained British Patent 4933 in 1880. From this year he began installing light bulbs in homes and landmarks in England. His house was the first in the world to be lit by a lightbulb and also the first house in the world to be lit by hydroelectric power. In 1878 the home of Lord Armstrong at Cragside was also among the first houses to be lit by electricity. In the early 1880s he had started his company. In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent lightbulbs, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.

Now answer this question: Why was Swan's first lamp not commercially viable?

Output:
'parchmentised thread'
