Question: Tranquility, also known as Node 3, is a module of the International Space Station (ISS). ESA and the Italian Space Agency had Tranquility built by Thales Alenia Space. A ceremony on November 20, 2009 transferred ownership of the module to NASA. On February 8, 2010, NASA launched the module on the Space Shuttle's STS-130 mission.

Tranquility was built within the ESA-NASA ISS bartering system. ESA committed to build and fund both Harmony and Tranquility as well as the ATV in order to use NASA ISS facitilies, fly astronauts on the Shuttle and for other ISS services. ESA teamed up with the Italian Space Agency ASI to build both Harmony and Tranquility at Thales Alenia Space in Turin.  Tranquility provides six berthing locations with power, data and commanding, thermal and environmental control, and crew access for more attached habitable volumes or for crew transportation vehicles or stowage, or an appropriate combination of all of these. One of the berthing locations is used by Cupola, which houses a Robotic Work Station inside it to assist in the assembly/maintenance of the ISS, and offers a window for Earth observations. Tranquility was launched with the Cupola attached to its port facing Common Berthing Mechanism (CBM). After mating Tranquility with the port CBM of Unity, the Cupola was transferred to the nadir facing port of Tranquility where it will stay.  The module has three redundant berthing ports that were not scheduled to be used prior to the end of the Space Shuttle program, although there is a Power Data Grapple Fixture reserved for the Special Purpose Dexterous Manipulator (Dextre), which is located on the zenith berthing location. The current ISS configuration requires Tranquility to be docked to the port berthing location of Unity. As such, the three unused berthing locations of Tranquility were disabled as the node's close proximity to other segments would prohibit the port's direct use for cargo spacecraft or using the docking module PMA-3, which was relocated from Harmony to the port berthing location of Tranquility for storage. At the time, the move of PMA-3 to the port location of Tranquility was required because NASA decided to leave the Multi-Purpose Logistics Module (MPLM) Leonardo permanently attached to the ISS, which will be located at the nadir side of Unity.  In 2001, NASA considered changing the design of the module. This idea for an extended or "stretched" module, was a result of the deferral/deletion of the Habitation Module. The stretched module would have held 16 racks, compared with the baseline capacity of eight racks. This modification was not funded and the plans were abandoned.

Question: 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.

Question: Howard Duane Allman (November 20, 1946 - October 29, 1971) was an American guitarist, session musician, and co-founder and leader of the Allman Brothers Band until his death following a motorcycle crash in 1971, at the age of 24. The Allman Brothers Band was formed in Jacksonville, Florida, in 1969. The band had great success in the early 1970s. Allman is best remembered for his brief but influential tenure in the band and in particular for his expressive slide guitar playing and inventive improvisational skills.

Duane Allman was born on November 20, 1946, in Nashville, Tennessee. He was the eldest son of Willis Allman (1918-1949), a World War II non-commissioned officer turned recruiting officer in the United States Army, and Geraldine Allman (nee Robbins) (1917-2015). His brother, Gregg, was born on December 8, 1947.  On December 26, 1949, when the family was living near Norfolk, Virginia, Willis Allman was murdered. In order to retrain as an accountant, Geraldine "Mama A" Allman sent Duane and Gregg to Castle Heights Military Academy in Lebanon, Tennessee, which they both disliked intensely. In 1957, the family moved to Daytona Beach, Florida, where the boys attended Seabreeze High School.  The boys returned to Nashville to spend summers with their grandmother, and there Gregg learned guitar basics from a neighbor. In 1960, he had saved enough money to buy his first guitar, a Japanese-made Teisco Silvertone, while Duane acquired a Harley 165 motorbike. Despite Duane being left-handed, he played the guitar right-handed. Duane began to take an interest in the guitar, and the boys would sometimes fight over it, until Duane wrecked the motorbike and traded it for a Silvertone of his own. His mother eventually bought Duane a Gibson Les Paul Junior.  It was also in Nashville that the boys became musically inspired by a rhythm and blues concert where they saw blues guitar legend B. B. King perform. Duane told Gregg, "We got to get into this." Duane learned to play very quickly and soon became the better guitarist of the two.
