Stan Grossfeld (born December 20, 1951) is an Associate editor at "The Boston Globe" who has won two Pulitzer Prizes for photojournalism.
 He was born in New York City and graduated from the Rochester Institute of Technology with a B.S. in Professional Photography in 1973.
 After two years in Newark, New Jersey, at "The Star-Ledger" he went to work for "The Boston Globe".
 While working there he completed a Master of Journalism at Boston University in 1980.
 He became chief photographer at the "Globe" in 1983.
 Next year he won the Pulitzer Prize for Spot News Photography for a "series of unusual photographs which reveal the effects of war on the people of Lebanon" (Lebanese Civil War, third phase).
 In 1985 he won the Feature Photography Pulitzer for a "series of photographs of the famine in Ethiopia and for his pictures of illegal aliens on the Mexican border."
 Named Associate Editor of the "Globe" in 1987, Grossfeld photographs many subjects, including sports.
David Joseph Bohm FRS (December 20, 1917 – October 27, 1992) was an American scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind.
Lindhard theory is a method of calculating the effects of electric field screening by electrons in a solid.
 It is based on quantum mechanics (first-order perturbation theory) and the random phase approximation.
Hans-Joachim Haase (1915 – December 20, 2001) was a German clockmaker, optician and inventor, who became known for an apparatus for testing binocular vision and for the "MKH method", an alternative method intended to improve binocular vision using corrective lenses.
 This method, which is controversial, has mainly found application in German-speaking countries.
The Vienna Ab initio Simulation Package, better known as VASP, is a package for performing ab initio quantum mechanical molecular dynamics (MD) using either Vanderbilt pseudopotentials, or the projector augmented wave method, and a plane wave basis set.
 The basic methodology is density functional theory (DFT), but the code also allows use of post-DFT corrections such as hybrid functionals mixing DFT and Hartree–Fock exchange, many-body perturbation theory (the GW method) and dynamical electronic correlations within the random phase approximation.
Clara Mabel Thompson (October 3, 1893 in Providence, Rhode Island – December 20, 1958) studied medicine at Johns Hopkins University and in her last year she was introduced to psychoanalysis.
 In the future years she developed as a psychoanalyst working with people like William Alanson White, Adolf Meyer, Harry Stack Sullivan, Joseph Cheesman Thompson, and Sándor Ferenczi.
 In the early 1940s Thompson founded the William Alanson White Psychiatric Foundation in New York together with Erich Fromm, Harry Stack Sullivan, Frieda Fromm-Reichmann, David Rioch and Janet Rioch (see www.wawhite.org).
 She worked there until her death on December 20, 1958
The Grandin Brothers; John Livingston Grandin (December 20, 1836 – September 10, 1912), William James Grandin (August 16, 1838 – December 7, 1904) and Elijah Bishop Grandin (December 20, 1840 – December 3, 1917) were a sibling trio of American entrepreneurs who were among the first to begin business ventures in commercial oil prospecting in the United States, and who later became involved in banking and Bonanza wheat farming.
 They eventually became titans of the wheat industry, operating the largest corporate wheat farm in the Dakota Territory (in Grandin, North Dakota) in the late 19th century –which was possibly the largest such farm in the United States at the time.
Random phase multiple access (RPMA) is the trade name given to a low-power wide-area channel access method product being sold by Ingenu, formerly On-Ramp Wireless.
 It is meant to be used for machine-to-machine (M2M) communication on the Internet of Things (IoT).
The random phase approximation (RPA) is an approximation method in condensed matter physics and in nuclear physics.
 It was first introduced by David Bohm and David Pines as an important result in a series of seminal papers of 1952 and 1953.
 For decades physicists had been trying to incorporate the effect of microscopic quantum mechanical interactions between electrons in the theory of matter.
 Bohm and Pines' RPA accounts for the weak screened Coulomb interaction and is commonly used for describing the dynamic linear electronic response of electron systems.
Hippolytus de Marsiliis (born 1451 Bologna; date of death unknown) was a lawyer and "doctor utriusque iuris" (Lat.
 'doctor of either law' — one who studied civil as well as canon law).
 He received his doctorate in 1480 but the date at which he became a lawyer is unknown.
 Throughout his life, he wrote many repetitiones and notabilia on many canons and decretals.
 In addition, he taught Roman law beginning in the year 1482.
 He is best known for documenting the Chinese water torture method, in which drops of water would consistently fall on a victim's forehead, causing him to go insane.
 He also was the first person to document sleep deprivation as a means of torture, wherein the interrogators would repeat same questions, shaking the victim at random intervals, pricking him with a sharp pin, or forcing him to march down a hallway endlessly.
 If the interrogators grew weary, they would switch out with another group, who then would ask the same questions (today police use this method, but it is known as the third degree).

Question: Which person who introduced the method of random phase approximation was born December 20, 1917?
Answer: David Bohm
