Louis Rosenhead
Louis Rosenhead CBE (1 January 1906 – 10 November 1984) was a British mathematician noted for his work on fluid mechanics, and was head of the Department of Applied Mathematics at Liverpool University from 1933 to 1973. Life Rosenhead was born in Mabgate, Leeds, on 1 January 1906 to parents from Poland, the first of three children. J. T. Stuart (1986) "Louis Rosenhead. 1 January 1906-10 November 1984", '' Biographical Memoirs of Fellows of the Royal Society'' 32: 407–420. His parents Abram Rozenkopf (born 1879) and Chaja Nagacz (born 1884) came from adjacent villages in Poland. They were married in Leeds in 1905, adopting the Anglicized versions of their names: Abraham and Ellen Rosenhead. Abraham was a tailor who did his national service in Russia and came to England in 1903; Ellen came in 1902. They were Jewish. William D. Rubinstein, Michael Jolles, Hilary L.

Fluid Mechanics
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology. It can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a ''macroscopic'' viewpoint rather than from ''microscopic''. Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), i ...

Fluid Dynamicists
In physics, a fluid is a liquid, gas, or other material that continuously deforms (''flows'') under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them. Although the term ''fluid'' generally includes both the liquid and gas phases, its definition varies among branches of science. Definitions of ''solid'' vary as well, and depending on field, some substances can be both fluid and solid. Viscoelastic fluids like Silly Putty appear to behave similar to a solid when a sudden force is applied. Substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment) as well. In particle physics, the concept is extended to include fluidic matters other than liquids or gases. A fluid in medicine or biology refers any liquid constituent of the body (body fluid), whereas "liquid" is not used in this sense. Sometimes liquids given for fl ...

Jewish Scientists
Jews ( he, יְהוּדִים, , ) or Jewish people are an ethnoreligious group and nation originating from the Israelites Israelite origins and kingdom: "The first act in the long drama of Jewish history is the age of the Israelites""The people of the Kingdom of Israel and the ethnic and religious group known as the Jewish people that descended from them have been subjected to a number of forced migrations in their history" and Hebrews of historical History of ancient Israel and Judah, Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, "Historically, the religious and ethnic dimensions of Jewish identity have been closely interwoven. In fact, so closely bound are they, that the traditional Jewish lexicon hardly distinguishes between the two concepts. Jewish religious practice, by definition, was observed exclusively by the Jewish people, and notions of Jewish peoplehood, nation, and community were suffused with faith in the Jewish God, ...

British Jews
British Jews (often referred to collectively as British Jewry or Anglo-Jewry) are British citizens who identify as Jewish. The number of people who identified as Jews in the United Kingdom rose by just under 4% between 2001 and 2021. History The first recorded Jewish community in Britain was brought to England in 1070 by King William the Conqueror, who believed that what he assumed to be its commercial skills would make his newly won country more prosperous. At the end of the 12th century, a series of blood libels and fatal pogroms hit England, particularly the east coast. Notably, on 16 March 1190, in the run up to the Third Crusade, the Jewish population of York was massacred at the site where Clifford's Tower now stands, and King Edward I of England passed the Statute of the Jewry (''Statutum de Judaismo'') in 1275, restricting the community's activities, most notably outlawing the practice of usury (charging interest).Prestwich, Michael.

Maurice Bartlett
Maurice Stevenson Bartlett FRS (18 June 1910 – 8 January 2002) was an English statistician who made particular contributions to the analysis of data with spatial and temporal patterns. He is also known for his work in the theory of statistical inference and in multivariate analysis. Biography Born in London, Bartlett was raised in a poor family but won a scholarship to Latymer Upper School in Hammersmith, where he was inspired to the study of statistics by a chapter in Hall and Knight's ''Algebra''. In 1929, he won a scholarship to Queens' College, Cambridge where he read mathematics, graduating with the rank of wrangler. He attended lectures on statistics by John Wishart, on relativity by Arthur Eddington and on quantum mechanics by Paul Dirac. In one of his lectures Wishart described his geometric derivation of the Wishart distribution. Overnight Bartlett worked out a proof using characteristic functions. Bartlett was Wishart's first post-graduate student and they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robin Plackett
Robin L. Plackett (3 September 1920 – 23 June 2009) was a statistician best known for his contributions to the history of statistics and to experimental design, most notably the Plackett–Burman designs. Early life and education Plackett attended Liverpool Collegiate School from 1932 to 1939. He then attended Clare College, Cambridge, where he graduated in 1942. Early career During World War II, Plackett was requested to work for the Ministry of Supply, in SR17 which was a statistical branch. He began to develop a methodology for applying statistical knowledge, and would pass it down to new recruits. First scientific paper In 1946, he would publish his first paper which was written jointly with Peter Burman in an journal called ''Biometrika''. The paper, titled "The design of optimum multifactorial experiments", introduced Plackett–Burman experimental designs. Academic career In 1947, he became a lecturer at Liverpool University.

Ballistics
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. A ballistic body is a free-moving body with momentum which can be subject to forces such as the forces exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight. A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight and the trajectory is subsequently governed by the laws of classical mechanics; in contrast to (for example) a cruise missile which is aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones and spears, and the throwing stic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
