Luis Walter Alvarez

Context: Alvarez's sister, Gladys, worked for Ernest Lawrence as a part-time secretary, and mentioned Alvarez to Lawrence. Lawrence then invited Alvarez to tour the Century of Progress exhibition in Chicago with him. After he completed his oral exams in 1936, Alvarez, now engaged to be married to Geraldine Smithwick, asked his sister to see if Lawrence had any jobs available at the Radiation Laboratory. A telegram soon arrived from Gladys with a job offer from Lawrence. This started a long association with the University of California, Berkeley. Alvarez and Smithwick were married in one of the chapels at the University of Chicago and then headed for California. They had two children, Walter and Jean. They were divorced in 1957. On December 28, 1958, he married Janet L. Landis, and had two more children, Donald and Helen. At the Radiation Laboratory he worked with Lawrence's experimental team, which was supported by a group of theoretical physicists headed by Robert Oppenheimer. Alvarez devised a set of experiments to observe K-electron capture in radioactive nuclei, predicted by the beta decay theory but never observed. Using magnets to sweep aside the positrons and electrons emanating from his radioactive sources, he designed a special purpose Geiger counter to detect only the "soft" X-rays coming from K capture. He published his results in the Physical Review in 1937. When deuterium (hydrogen-2) is bombarded with deuterium, the fusion reaction yields either tritium (hydrogen-3) plus a proton or helium-3 plus a neutron (2H + 2H - 3H + p or 3He + n). This is one of the most basic fusion reactions, and the foundation of the thermonuclear weapon and the current research on controlled nuclear fusion. At that time the stability of these two reaction products was unknown, but based on existing theories Hans Bethe thought that tritium would be stable and helium-3 unstable. Alvarez proved the reverse by using his knowledge of the details of the 60-inch cyclotron operation. He tuned the machine to accelerate doubly ionized helium-3 nuclei and was able to get a beam of accelerated ions, thus using the cyclotron as a kind of super mass spectrometer. As the accelerated helium came from deep gas wells where it had been for millions of years, the helium-3 component had to be stable. Afterwards Alvarez produced the radioactive tritium using the cyclotron and the 2H + 2H reaction and measured its lifetime. In 1938, again using his knowledge of the cyclotron and inventing what are now known as time-of-flight techniques, Alvarez created a mono-energetic beam of thermal neutrons. With this he began a long series of experiments, collaborating with Felix Bloch, to measure the magnetic moment of the neutron. Their result of m0 = 1.93+-0.02 mN, published in 1940, was a major advance over earlier work. CANNOTANSWER

Lady Randolph Churchill

Context: Lord Randolph died in 1895, aged 45. His death freed Jennie to move effortlessly in spite of her impecuniosity; she mixed in the highest London society circles, and was much-admired by the Prince of Wales. Attending a party hosted by Daisy Warwick, Jennie was introduced to George Cornwallis-West, who was just 26 days older than Winston; he was instantly smitten, and they spent much time together. A captain in the Scots Guards, George had two sisters: Constance (known as Shelagh) was the first wife of the 2nd Duke of Westminster; Daisy was married to the Prince of Pless. George and Jennie were married on 28 July 1900 at St Paul's Church, Knightsbridge. Around this time, Jennie became well-known for chartering the hospital ship RFA Maine to care for those wounded in the Second Boer War, for which she received the decoration of the Royal Red Cross (RRC) in the South Africa Honours list published on 26 June 1902. In 1908, she wrote her memoirs The Reminiscences of Lady Randolph Churchill. George doted on Jennie, amorously nicknaming her "pussycat". However, they drifted apart. The Churchills were becoming a dedicated-literary family, and George, who was a financial failure in the City, slowly fell out of love with his wife, who was old enough to be his mother. Short of money, Jennie contemplated selling the family home in Hertfordshire to move into the Ritz Hotel in Piccadilly. George was in fragile health when he recuperated at the royal skiing resort of St Moritz. Jennie took to writing plays for the West End, in many of which the star was Mrs. Patrick Campbell. Jennie separated from George in 1912, and they were divorced in April 1914, whereupon, in a bit of irony, Cornwallis-West married Mrs. Campbell. Jennie dropped the surname Cornwallis-West, and resumed, by deed poll, the name Lady Randolph Churchill. Her third marriage, on 1 June 1918, was to Montagu Phippen Porch (1877-1964), a member of the British Civil Service in Nigeria, who was younger than Winston by three years. At the end of World War I, Porch resigned from the colonial service. After Jennie's death, he returned to West Africa, where his business investments had proven successful. CANNOTANSWER

Lady Randolph Churchill

Context: Lord Randolph died in 1895, aged 45. His death freed Jennie to move effortlessly in spite of her impecuniosity; she mixed in the highest London society circles, and was much-admired by the Prince of Wales. Attending a party hosted by Daisy Warwick, Jennie was introduced to George Cornwallis-West, who was just 26 days older than Winston; he was instantly smitten, and they spent much time together. A captain in the Scots Guards, George had two sisters: Constance (known as Shelagh) was the first wife of the 2nd Duke of Westminster; Daisy was married to the Prince of Pless. George and Jennie were married on 28 July 1900 at St Paul's Church, Knightsbridge. Around this time, Jennie became well-known for chartering the hospital ship RFA Maine to care for those wounded in the Second Boer War, for which she received the decoration of the Royal Red Cross (RRC) in the South Africa Honours list published on 26 June 1902. In 1908, she wrote her memoirs The Reminiscences of Lady Randolph Churchill. George doted on Jennie, amorously nicknaming her "pussycat". However, they drifted apart. The Churchills were becoming a dedicated-literary family, and George, who was a financial failure in the City, slowly fell out of love with his wife, who was old enough to be his mother. Short of money, Jennie contemplated selling the family home in Hertfordshire to move into the Ritz Hotel in Piccadilly. George was in fragile health when he recuperated at the royal skiing resort of St Moritz. Jennie took to writing plays for the West End, in many of which the star was Mrs. Patrick Campbell. Jennie separated from George in 1912, and they were divorced in April 1914, whereupon, in a bit of irony, Cornwallis-West married Mrs. Campbell. Jennie dropped the surname Cornwallis-West, and resumed, by deed poll, the name Lady Randolph Churchill. Her third marriage, on 1 June 1918, was to Montagu Phippen Porch (1877-1964), a member of the British Civil Service in Nigeria, who was younger than Winston by three years. At the end of World War I, Porch resigned from the colonial service. After Jennie's death, he returned to West Africa, where his business investments had proven successful. CANNOTANSWER
