Question:
Cuban was born in Pittsburgh, Pennsylvania. His father, Norton Cuban, was an automobile upholsterer, while Cuban has described his mother, Shirley, as someone with "a different job or different career goal every other week." He grew up in the suburb of Mount Lebanon, in a Jewish working-class family. His paternal grandfather changed the family name from "Chabenisky" to "Cuban" after his family emigrated from Russia through Ellis Island.
On January 4, 2000, Cuban purchased a majority stake in the NBA's Dallas Mavericks for $285 million from H. Ross Perot, Jr.  In the 20 years before Cuban bought the team, the Mavericks won only 40% of their games, and a playoff record of 21-32. In the 10 years following, the team won 69 percent of their regular season games and reached the playoffs in each of those seasons except for one. The Mavericks' playoff record with Cuban is 49 wins and 57 losses, including their first trip to the NBA Finals in 2006, where they lost to the Miami Heat.  On June 12, 2011, the Mavericks defeated the Heat to win the NBA Finals. Historically, NBA team owners publicly play more passive roles and watch basketball games from skyboxes; Cuban sits alongside fans while donning team jerseys. Cuban travels in his private airplane--a Gulfstream V--to attend road games.  In May 2010, H. Ross Perot, Jr., who retained 5% ownership, filed a lawsuit against Cuban, alleging the franchise was insolvent or in imminent danger of insolvency. In June 2010, Cuban responded in a court filing maintaining Perot is wrongly seeking money to offset some $100 million in losses on the Victory Park real estate development. The lawsuit was dismissed in 2011, due in part to Cuban asserting proper management of the team due to its recent victory in the 2011 NBA Finals. In 2014, the 5th Circuit Court affirmed that decision on appeal. Following his initial defeat, Perot attempted to shut out Mavericks fans from use of the parking lots he controlled near the American Airlines Center.  In January 2018, Cuban announced the Mavericks would be accepting Bitcoin as payment for tickets in the following season.

input: Paul attended Moorestown Friends School, where she graduated at the top of her class. In 1901, Paul went to Swarthmore College, an institution co-founded by her grandfather. While attending Swarthmore, Paul served as a member on the Executive Board of Student Government, one experience which may have sparked her eventual excitement for political activism. Alice graduated from Swarthmore College with a bachelor's degree in biology in 1905.  Partly in order to avoid going into teaching work, Paul completed a fellowship year at a settlement house in New York City after her graduation, living on the Lower East Side at the College Settlement House. While working on settlement activities taught her about the need to right injustice in America, Alice soon decided that social work was not the way she was to achieve this goal: "I knew in a very short time I was never going to be a social worker, because I could see that social workers were not doing much good in the world... you couldn't change the situation by social work."  Paul then earned a master of arts from the University of Pennsylvania in 1907, after completing coursework in political science, sociology and economics. She continued her studies at the Woodbrooke Quaker Study Centre in Birmingham, England, and took economics classes from the University of Birmingham, while continuing to earn money doing social work. She first heard Christabel Pankhurst speak at Birmingham. When she later moved to London to work, she joined the militant suffrage group the Women's Social and Political Union (WSPU) led by Christabel and her mother, Emmeline Pankhurst. She was arrested repeatedly during suffrage demonstrations and served three jail terms. After returning from England in 1910, Paul continued her studies at the University of Pennsylvania, earning a Ph.D. in sociology. Her dissertation was entitled "The Legal Position of Women in Pennsylvania"; it discussed the history of the women's movement in Pennsylvania and the rest of the U.S., and urged woman suffrage as the key issue of the day.  Paul later received her law degree (LL.B) from the Washington College of Law at American University in 1922, after the suffrage fight was over. In 1927, she earned a master of laws degree, and in 1928, a doctorate in civil law from American University.

Answer the question at the end by quoting:

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.
