I. Bernard Cohen
I. Bernard Cohen (1 March 1914 – 20 June 2003) was an American historian of science. He taught at Harvard University for 60 years, 1942–2002, becoming the first chair of its Department of the History of Science when it was established in 1966, and he mentored notable students including George Basalla, Lorraine Daston, and Allen G. Debus. He was the author of many books on the history of science and, in particular, on Isaac Newton, Benjamin Franklin, and Howard H. Aiken. He made a full English translation of Newton's ''Principia Mathematica'' and was the second chief editor of the history of science journal ''Isis''. Early life and education I. Bernard Cohen was born 1 March 1914 in Far Rockaway, New York City, to Isadore and Blanche Cohen; he had one older sister, Harriet. His father died just before Cohen's bar mitzvah at age 12, and Cohen became unmotivated and spent the next years performing unremarkably in schools and early jobs; he attended Columbia Grammar Schoo ...

Historian Of Science
The history of science covers the development of science from ancient history, ancient times to the present. It encompasses all three major branches of science: natural science, natural, social science, social, and formal science, formal. Protoscience, Science in the ancient world, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment. The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of Science in classical antiquity, classical antiquity, wherein formal attempts were made to provide explanations of events in the Universe, physical world based on n ...

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease.

History Of Science Society
The History of Science Society (HSS), founded in 1924, is the primary professional society for the academic study of the history of science. The society has over 3,000 members worldwide. It publishes the quarterly journal ''Isis'' and the yearly journal ''Osiris'', sponsors the IsisCB: History of Science Index, and holds an annual conference. , the current president of the HSS is Evelynn M. Hammonds. History The History of Science Society was founded in 1924 by George Sarton, David Eugene Smith, and Lawrence Joseph Henderson, primarily to support the publication of ''Isis'', a journal of the history of science Sarton had started in 1912 in Belgium. George Sarton edited the journal ''Isis'' from 1913 until 1952, when he retired. Bernard Cohen served as managing editor of ''Isis'' from 1947 to 1952 and took over as editor from 1952 to 1958. Subsequent editors of ''Isis'' include Harry Woolf, 1959–1963; Robert P. Multhauf, 1964–1978; Arnold Thackray (1979–1985); Charle ...

Poincaré Recurrence Theorem
In mathematics and physics, the Poincaré recurrence theorem states that certain dynamical systems will, after a sufficiently long but finite time, return to a state arbitrarily close to (for continuous state systems), or exactly the same as (for discrete state systems), their initial state. The Poincaré recurrence time is the length of time elapsed until the recurrence. This time may vary greatly depending on the exact initial state and required degree of closeness. The result applies to isolated mechanical systems subject to some constraints, e.g., all particles must be bound to a finite volume. The theorem is commonly discussed in the context of ergodic theory, dynamical systems and statistical mechanics. Systems to which the Poincaré recurrence theorem applies are called conservative systems. The theorem is named after Henri Poincaré, who discussed it in 1890. A proof was presented by Constantin Carathéodory using measure theory in 1919. Precise formulation Any dynam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamical Billiards
A dynamical billiard is a dynamical system in which a particle alternates between free motion (typically as a straight line) and specular reflections from a boundary. When the particle hits the boundary it reflects from it Elastic collision, without loss of speed (i.e. elastic collisions). Billiards are Hamiltonian mechanics, Hamiltonian idealizations of the billiards, game of billiards, but where the region contained by the boundary can have shapes other than rectangular and even be multidimensional. Dynamical billiards may also be studied on non-Euclidean geometry, non-Euclidean geometries; indeed, the first studies of billiards established their ergodic theory, ergodic motion on surface (mathematics), surfaces of constant negative curvature. The study of billiards which are kept out of a region, rather than being kept in a region, is known as outer billiard theory. The motion of the particle in the billiard is a straight line, with constant energy, between reflections with the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemical Physics
Chemical physics is a branch of physics that studies chemical processes from a physical point of view. It focuses on understanding the physical properties and behavior of chemical systems, using principles from both physics and chemistry. This field investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics. The United States Department of Education defines chemical physics as "A program that focuses on the scientific study of structural phenomena combining the disciplines of physical chemistry and atomic/molecular physics. Includes instruction in heterogeneous structures, alignment and surface phenomena, quantum theory, mathematical physics, statistical and classical mechanics, chemical kinetics, and laser physics." Distinction between chemical physics and physical chemistry While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry as it focuses more on using physical ...

Valley Forge Military Academy And College
Valley Forge Military Academy and College (VFMAC) is a private boarding school (grades 7–12) and military junior college in Wayne, Pennsylvania. It follows in the traditional military school format with army traditions. The high-school portion of VFMAC, Valley Forge Military Academy, is a college-preparatory boarding school specializing in student leadership. Valley Forge Military College is the only private military junior college in the United States. The academy and college were once fully residential, but the academy now offers a day-student program. All VFMAC students join the student-run Corps of Cadets, an honor they earn by passing a board examination to earn a " capshield". It is one of only two corps of cadets in the United States to retain a traditional mounted battalion ( squadron), consisting of one cavalry troop and one artillery battery. It is the only American military organization that maintains British military rank, drill, customs, and ceremonies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rum Runner
Rum-running, or bootlegging, is the illegal business of smuggling alcoholic beverages where such transportation is forbidden by law. The term ''rum-running'' is more commonly applied to smuggling over water; ''bootlegging'' is applied to smuggling over land. Smuggling circumvents alcohol taxes and outright prohibition of alcohol sales. Alcohol smuggling today In the United States, the smuggling of alcohol did not end with the repeal of prohibition. In the Appalachian United States, for example, the demand for moonshine was at an all-time high in the 1920s, but an era of rampant bootlegging in dry areas continued into the 1970s. Although the well-known bootleggers of the day may no longer be in business, bootlegging still exists, even if on a smaller scale. The state of Virginia has reported that it loses up to $20 million a year from illegal whiskey smuggling. The Government of the United Kingdom fails to collect an estimated £900 million in taxes due to alcohol smuggling ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prohibition In The United States
The Prohibition era was the period from 1920 to 1933 when the United States prohibited the production, importation, transportation, and sale of alcoholic beverages. The alcohol industry was curtailed by a succession of state legislatures, and Prohibition was formally introduced nationwide under the Eighteenth Amendment to the United States Constitution, ratified on January 16, 1919. Prohibition ended with the ratification of the Twenty-first Amendment to the United States Constitution, Twenty-first Amendment, which repealed the Eighteenth Amendment on December 5, 1933. Led by Pietism, Pietistic Protestantism in the United States, Protestants, prohibitionists first attempted to end the trade in alcoholic drinks during the 19th century. They aimed to heal what they saw as an ill society beset by alcohol-related problems such as alcoholism, domestic violence, and Saloon bar, saloon-based political corruption. Many communities introduced alcohol bans in the late 19th and early 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
