IN: Giuliani was born in an Italian-American enclave in East Flatbush in the New York City borough of Brooklyn, the only child of working-class parents, Harold Angelo Giuliani (1908-1981) and Helen Giuliani (nee D'Avanzo; 1909-2002), both children of Italian immigrants. Giuliani is of Tuscan origins from his father side, as his paternal grandparents (Rodolfo and Evangelina Giuliani) were born in Montecatini, Tuscany, Italy. He was raised a Roman Catholic. Harold Giuliani, a plumber and a bartender, had trouble holding a job, and was convicted of felony assault and robbery, serving time in Sing Sing.

Due to term limits, Giuliani could not run in 2001 for a third term as Mayor. In November 1998, four-term incumbent Democratic U.S. Senator Daniel Patrick Moynihan announced his retirement and Giuliani immediately indicated an interest in running in the 2000 election for the now-open seat. Due to his high profile and visibility Giuliani was supported by the state Republican Party. Giuliani's entrance led Democratic Congressman Charles Rangel and others to recruit then-U.S. First Lady Hillary Clinton to run for Moynihan's seat, hoping she might combat his star power. An early January 1999 poll showed Giuliani trailing Clinton by 10 points. In April 1999, Giuliani formed an exploratory committee in connection with the Senate run. By January 2000, Giuliani had reversed the polls situation, pulling nine points ahead after taking advantage of several campaign stumbles by Clinton. Nevertheless, the Giuliani campaign was showing some structural weaknesses; so closely identified with New York City, he had somewhat limited appeal to normally Republican voters in Upstate New York. The New York Police Department's fatal shooting of Patrick Dorismond in March 2000 inflamed Giuliani's already strained relations with the city's minority communities, and Clinton seized on it as a major campaign issue. By April 2000, reports showed Clinton gaining upstate and generally outworking Giuliani, who stated that his duties as mayor prevented him from campaigning more. Clinton was now 8 to 10 points ahead of Giuliani in the polls. Then followed four tumultuous weeks, in which Giuliani's medical life, romantic life, marital life, and political life all collided at once in a most visible fashion. Giuliani discovered that he had prostate cancer and needed treatment; his extramarital relationship with Judith Nathan became public and the subject of a media frenzy; he announced a separation from his wife Donna Hanover; and, after much indecision, on May 19, 2000 he announced his withdrawal from the Senate race.

What was a major topic that was discussed by the candidates during the campaign?

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.
