Problem: Sonata Arctica is a Finnish power metal band from the town of Kemi, Finland. Created as a hard rock band named Tricky Beans, they later changed to Tricky Means and finally to Sonata Arctica, when they shifted to power metal. The current line-up consists of singer, keyboardist and songwriter Tony Kakko, guitarist Elias Viljanen, bass guitarist Pasi Kauppinen, keyboardist and keytarist Henrik Klingenberg, and drummer Tommy Portimo. All the musicians of the band's history except Portimo also acted as backing vocalists.

On May 25, 2007, Unia was released. The album's first single, "Paid In Full", was released on April 27, 2007. On August 6, 2007, the band announced on their website that guitarist Jani Liimatainen had been asked to leave the band due to problems related to his conscription. He was replaced by Elias Viljanen who had already filled in for him in the band's Finnish and Japanese shows during the spring and summer. In October 2007 Sonata Arctica headlined the ProgPower USA VIII. Later the band supported Nightwish across their 2008 tour of United States and Canada and headlined at the shows that Nightwish cancelled due to Anette Olzon's sudden severe sickness. It was announced on September 4, 2008 that the band's first two albums would be re-released with bonus tracks by Spinefarm UK on October 6. The Days of Grays was released on September 16, 2009 in Finland and September 22 in the USA. Henrik stated that the new album would be in the same vein as Unia, but not as complex and darker. Singles from this album include "Flag in the Ground" and "The Last Amazing Grays". On August 28, 2009, the music video of "Flag In The Ground" was released to the web. The limited 2CD European edition of the album featured many of the album tracks with all instruments performed by a symphony orchestra.

Problem: Robert Dennis Crumb (; born August 30, 1943) is an American cartoonist and musician who often signs his work R. Crumb. His work displays a nostalgia for American folk culture of the late 19th and early 20th centuries, and satire of contemporary American culture. Crumb is a prolific artist and contributed to many of the seminal works of the underground comix movement in the 1960s, including being a founder of the first successful underground comix publication, Zap Comix, contributing to all 16 issues. He was additionally contributing to the East Village Other and many other publications, including a variety of one-off and anthology comics.

Crumb's father gave him $40 when he left home after high school. His first job, in 1962, was drawing novelty greeting cards for American Greetings in Cleveland, Ohio. He stayed with the company for four years, producing hundreds of cards for the company's Hi-Brow line; his superiors had him draw in a cuter style that was to leave a footprint on his work throughout his career. In Cleveland he met a group of young bohemians such as Buzzy Linhart, Liz Johnston, and Harvey Pekar. Dissatisfied with greeting card work, he tried to sell cartoons to comic book companies, who showed little interest in his work. In 1965, cartoonist Harvey Kurtzman printed some of Crumb's work in the humor magazine he edited, Help!. Crumb moved to New York, intending to work with Kurtzman, but Help! ceased publication shortly after. Crumb briefly illustrated bubblegum cards for Topps before returning to Cleveland and American Greetings. Crumb married Dana Morgan in 1964. Nearly destitute, the couple traveled in Europe, during which Crumb continued to produce work for Kurtzman and American Greetings, and Dana stole food. The relationship was unstable as Crumb frequently went his own way, and he was not close to his son Jesse (b. 1965). In 1965 and 1966 Crumb had a number of Fritz the Cat strips published in the men's magazine Cavalier. Fritz had appeared in Crumb's work as early as the late 1950s; he was to become a hipster, scam artist, and bohemian until Crumb abandoned the character in 1969. Crumb was becoming increasingly uncomfortable with his job and marriage when in June 1965 he began taking LSD, a psychedelic drug that was then still legal. He had both good and bad trips. One bad trip left him in a muddled state for half a year, during which for a time he left Dana; the state ended when the two took a strong dose of the drug together in April 1966. Crumb created a number of his best-known characters during his years of LSD use, including Mr. Natural, Angelfood McSpade, and the Snoid.

Problem: William Thomson, 1st Baron Kelvin, (26 June 1824 - 17 December 1907) was a Scots-Irish mathematical physicist and engineer who was born in Belfast in 1824. At the University of Glasgow he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its modern form. He worked closely with mathematics professor Hugh Blackburn in his work.

Though now eminent in the academic field, Thomson was obscure to the general public. In September 1852, he married childhood sweetheart Margaret Crum, daughter of Walter Crum; but her health broke down on their honeymoon and, over the next seventeen years, Thomson was distracted by her suffering. On 16 October 1854, George Gabriel Stokes wrote to Thomson to try to re-interest him in work by asking his opinion on some experiments of Michael Faraday on the proposed transatlantic telegraph cable. Faraday had demonstrated how the construction of a cable would limit the rate at which messages could be sent - in modern terms, the bandwidth. Thomson jumped at the problem and published his response that month. He expressed his results in terms of the data rate that could be achieved and the economic consequences in terms of the potential revenue of the transatlantic undertaking. In a further 1855 analysis, Thomson stressed the impact that the design of the cable would have on its profitability. Thomson contended that the signalling speed through a given cable was inversely proportional to the square of the length of the cable. Thomson's results were disputed at a meeting of the British Association in 1856 by Wildman Whitehouse, the electrician of the Atlantic Telegraph Company. Whitehouse had possibly misinterpreted the results of his own experiments but was doubtless feeling financial pressure as plans for the cable were already well under way. He believed that Thomson's calculations implied that the cable must be "abandoned as being practically and commercially impossible." Thomson attacked Whitehouse's contention in a letter to the popular Athenaeum magazine, pitching himself into the public eye. Thomson recommended a larger conductor with a larger cross section of insulation. However, he thought Whitehouse no fool and suspected that he might have the practical skill to make the existing design work. Thomson's work had, however, caught the eye of the project's undertakers and in December 1856, he was elected to the board of directors of the Atlantic Telegraph Company.
