IN: James Watt (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.

From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret. With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success. By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.

How does he discover this mixture?

Answer the question at the end by quoting:

John Michael Stipe (born January 4, 1960) is an American musician and singer-songwriter. He is best known as the lead singer and main lyricist of the alternative rock band R.E.M. from their formation in 1980 until their dissolution in 2011. Possessing a distinctive voice, Stipe is noted for the "mumbling" style of his early career as well as for his social and political activism. He was in charge of R.E.M.'s visual aspect, often selecting album artwork and directing many of the band's music videos.
While attending college at the University of Georgia in Athens, Stipe frequented the Wuxtry record shop, where he met store clerk Peter Buck in 1980. "He was a striking-looking guy and he also bought weird records, which not everyone in the store did", Buck recalled. The two became friends and eventually decided to form a band. Buck and Stipe started writing music together; at the time Stipe also spent time in a local group named Gangster. The pair were soon joined by Bill Berry and Mike Mills and named themselves R.E.M., a name Stipe selected at random from a dictionary. All four members of R.E.M. dropped out of school in 1980 to focus on the band. Stipe was the last to do so. The band issued its debut single, "Radio Free Europe", on Hib-Tone, which was a college radio success. The band signed to I.R.S. Records for the release of the Chronic Town EP one year later. R.E.M. released its debut album Murmur in 1983, which was acclaimed by critics. Stipe's vocals and lyrics received particular attention from listeners. Murmur went on to win the Rolling Stone Critics Poll Album of the Year over Michael Jackson's Thriller. Their second album, Reckoning, followed in 1984. In 1985, R.E.M. traveled to England to record their third album Fables of the Reconstruction, a difficult process that brought the band to the verge of a break up. After the album was released, relationships in the band remained tense. Gaining weight and acting eccentrically (such as by shaving his hair into a monk's tonsure), Stipe later said of the period, "I was well on my way to losing my mind". They toured in Canada and throughout Europe that year; Stipe had bleached his hair blond during this time.

What year did they form?

All four members of R.E.M. dropped out of school in 1980 to focus on the band.

input: Jason Flom, Atlantic Records's head of A&R, recommended that they meet David Foster, a Canadian musician, producer, composer and arranger. The Corrs played live for Foster and he agreed to sign them to Atlantic Records. They extended their stay in the US for over five months to record their debut album, Forgiven, Not Forgotten. It featured six instrumental selections among its Celtic-influenced tracks. The album sold well in Ireland, Australia, Japan, Norway and Spain. Major success in the US and the UK, however, was not immediately forthcoming. Eventually, the album reached Platinum status in the UK and Australia, and 4x Platinum in Ireland, making it one of the most successful debuts by an Irish group. The Corrs' next album, 1997's Talk on Corners, was produced by Glen Ballard, who was respected for his collaboration with Alanis Morissette. The Corrs also collaborated with Carole Bayer Sager, Oliver Leiber, Rick Nowels and Billy Steinberg. The album met with lukewarm response. It was successful in Ireland and entered the Australian album charts at number 3. After the band recorded a version of Dreams for a Fleetwood Mac tribute album, they re-released Talk on Corners, with new remixes of "What Can I Do?", "So Young" and "Runaway". The special edition topped the charts worldwide and again reached multi-Platinum status in the UK and Australia. In June 1998, The Corrs participated in the Pavarotti and Friends for the Children of Liberia charity concert. The concert was held in Modena, Italy and was hosted by Luciano Pavarotti. Other performers included Jon Bon Jovi, Celine Dion, Spice Girls and Stevie Wonder. The concert aimed to raise money to build the Pavarotti and Friends Liberian Children's Village, to provide refuge for children in Liberia. The following year, The Corrs received a BRIT Award for Best International Band. They performed live on MTV's Unplugged on 5 October 1999 at Ardmore Studios, Co. Wicklow, Ireland. The resulting CD and DVD sold 2.7 million copies and featured live performances of previously released songs, plus a new song, "Radio", later featured on their third album, In Blue.
