Transcript of Science & Inventors

Ms. Cruz Pd. 2nd Scientist & Inventors Physicist Melvin Schwartz Inventor William Henry Gates 3rd (Bill Gates) Born in 1932 Professor in 1963 Dies August 28, 2006 Undergraduate in 1949 Assistant Professor in 1958 Associate Professor in 1960 1966, after having spent 17 years at Columbia, he decided to move West to Stanford, where a new accelerator was just being completed February 1991 when I became Associate Director, High Energy and Nuclear Physics, at Brookhaven National Laboratory. "Melvin Schwartz - Autobiography". Nobelprize.org. 11 Dec 2012 http://www.nobelprize.org/nobel_prizes/physics/laureates/1988/schwartz-autobio.html Co-Founder in 1988 for neutrino beam method and the demonstration of the doublet structure of the leptons through the discovery of the muon neutrino Schwartz performed his Ph.D. thesis research through 1956 at the Laboratory's first accelerator, the Cosmotron. While finishing his thesis, he was employed by the Laboratory from 1956-58. In 1970, Schwartz founded a major computer-security company, Digital Pathways, Inc Nobel Prize Winner Born on June 20, 1861 Hopkins died in 1947, at the age of 86 He was awarded the Royal Medal of the Royal Society of London in 1918 Hopkins was knighted in 1925 and received the Order of Merit in 1935. In 1921 he isolated a substance which he named glutathione, which is, he showed, widely distributed in the cells of plants and animals that are rapidly multiplying. Later he proved it to be the tripeptide of glutamic acid, glycine and cystein. In 1902 he was given a readership in biochemistry born on October 28, 1955 interest in computer programming at the age of 13 Bill Gates graduated from Lakeside in 1973. Gates placed himself as the head of Microsoft, which grossed $2.5 million in 1978. Gates was only 23. In November 1980, IBM was looking for software that would operate their upcoming personal computer (PC) and approached Microsoft. In November 1985, Bill Gates and Microsoft launched Windows; nearly two years after his announcement In 1994, Gates and his wife established the William H. Gates Foundation which was dedicated to supporting education, world health, and investment in low-income communities. In 1987, Bill Gates became a billionaire when the stock raised to $90.75 a share. In 1999, with stock prices at an all time high and the stock splitting eight-fold since its IPO, Gates' wealth briefly topped $101 billion. Between 1978 and 1981, Microsoft's growth exploded, and staff increased from 25 to 128. Revenue also shot up from $4 million to $16 million. Woman Born August 1, 1905 At the age of five she was allowed outdoors in the evening to witness the 1910 appearance of Halley's Comet. Went to Mount Holyoke College to study chemistry in 1922. In 1939 Hogg published the first complete catalog of 1,116 variable stars. Died on January 28, 1993 1975 article she explained the meaning of "a blue moon," Helen Sawyer Hogg There are about 130 global clusters surrounding the Milky Way Galaxy. These clusters were the first stellar formations and each contains thousands of stars. Hogg specialized in the study of variable stars which change in size, temperature, and brightness. Tracking a single star's cycle could take hundreds of days and if something interfered with the observations, such as clouds or a scheduling conflict, the astronomer had to wait a year to continue following the cycle. "a blue moon," which she said was most likely caused by certain types of dust particles that are slightly larger than a wavelength of light. These particles filter red light, but allow blue light to pass through, thereby creating the illusion of a blue moon. Hogg continued to write the popular column until 1981. "Harry S. Truman." 2012.

High Acheving but Challanged Born on May 8, 1884 When World War I erupted, Truman volunteered for duty. Truman was elected to the United States Senate in 1934. He died on December 26, 1972 He served as vice president just 82 days before Roosevelt died of a massive stroke, and he was sworn in as president on April 12, 1945. Harry S. Truman In his first months in office he dropped the atomic bomb on Japan, ending World War II. His policy of communist containment started the Cold War, and he initiated U.S. involvement in the Korean War. Did not attend college. He worked a variety of jobs after high school.

Web. 10 Dec 2012. <http://www.answers.com/topic/helen-sawyer-hogg>. Chemist Born on August 30, 1871 In 1889 he was awarded a University scholarship Died October 19, 1937 1907 to become Langworthy Professor of Physics In 1898 he reported the existence of alpha and beta rays in uranium radiation and indicated some of their properties. In 1910, his investigations into the scattering of alpha rays and the nature of the inner structure of the atom which caused such scattering led to the postulation of his concept of the "nucleus", his greatest contribution to physics. Ernest Rutherford Frederick Soddy arrived at McGill in 1900 from Oxford, and he collaborated with Rutherford in creating the "disintegration theory" of radioactivity which regards radioactive phenomena as atomic - not molecular - processes. Otto Hahn, who later discovered atomic fission, worked under Rutherford at the Montreal Laboratory in 1905-06. Celebrity/Hero February 12, 1809 When young Abraham was 9 years old his mother died of tremetol (milk sickness) at age 34 and the event was devastating on him. September 22, 1862, Abraham felt confident enough to reshape the cause of the war from “union” to abolishing slavery. On March 28, 1865, General Robert E. Lee, commander of the Army of Virginia, surrendered his forces to Union General Ulysses S. Grant and the war for all intents and purposes was over. Died April 15, 1865 Abraham Lincon Lincoln was assassinated on April 14, 1865, by well-known actor and Confederate sympathizer John Wilkes Booth at Ford’s Theater in Washington, D.C. He distributed $2,000,000 from the Treasury for war materiel without an appropriation from Congress; he called for 75,000 volunteers into military service without a declaration of war; and he suspended the writ of habeas corpus, arresting and imprisoning suspected Confederate sympathizers without a warrant. Abraham Lincoln served a single term in the U.S. House of Representatives from 1847-'49. "Abraham Lincoln." 2012. The Biography Channel website.

Frederick Gowland Hopkins In 1894, when he was 32 years old, he graduated in medicine and taught for four years physiology and toxicology at Guy's Hospital. In 1921 he isolated a substance which he named glutathione, which is, he showed, widely distributed in the cells of plants and animals that are rapidly multiplying. Later he proved it to be the tripeptide of glutamic acid, glycine and cystein. He also discovered xanthine oxidase, a specific enzyme widely distributed in tissues and milk, which catalyzes the oxidation of the purine bases xanthine and hypoxanthine to uric acid. Hopkins thus returned to the uric acids of his earliest work, a method of determining uric acid in urine, which he first published in 1891. By Agustin Pena
