Roy Kerr
Roy Patrick Kerr (; born 16 May 1934) is a New Zealand mathematician who discovered the Kerr metric, Kerr geometry, an exact solutions in general relativity, exact solution to the Einstein field equation of general relativity. His solution models the gravitational field outside an uncharged rotating massive object, including a rotating black hole.''Cracking the Einstein Code''
by Fulvio Melia, 2009
His solution to Einstein's equations predicted spinning black holes before they were discovered.


Early life and education

Kerr was born in 1934 in Kurow, New Zealand. He was born into a dysfunctional family, and his mother was forced to leave when he was three. When his father went to war, he was sent to a farm. After his father's return from war, they moved to ...

Crafoord Prize
The Crafoord Prize is an annual science prize established in 1980 by Holger Crafoord, a Swedish industrialist, and his wife Anna-Greta Crafoord. The Prize is awarded in partnership between the Royal Swedish Academy of Sciences and the Crafoord Foundation in Lund. The Academy is responsible for selecting the Crafoord Laureates. The prize is awarded in four categories: astronomy and mathematics; Geology, geosciences; Biology, biosciences, with particular emphasis on ecology; and polyarthritis, the disease from which Holger severely suffered in his last years. According to the Academy, "these disciplines are chosen so as to complement those for which the Nobel Prizes are awarded". Only one award is given each year, according to a rotating scheme – astronomy and mathematics; then geosciences; then biosciences. A Crafoord Prize in polyarthritis is only awarded when a special committee decides that substantial progress in the field has been made. The recipient of the Crafoord Prize is a ...

Kurow
Kurow is a small town in the Waitaki District, New Zealand. It is located on the south bank of the Waitaki River, northwest of Oamaru. Description The name is an Anglicised form of the Māori name of the nearby mountain, Te Kohurau. In the 1920s, the town was the base for the building of the nearby Waitaki Dam and forming Lake Waitaki in the first of a series of hydroelectric projects on the Waitaki River. The first social security scheme for New Zealand workers was designed in the town, arising from Presbyterian Minister of Kurow Arnold Nordmeyer's experience of working with families of workers on the Waitaki hydro-electric project. Examples of pre-European Māori cave paintings are close to the small settlement of Duntroon. The land around the town includes summerfruit orchards, and increasing amounts of Pinot noir are being planted in the limestone soils. In 2021, there were 13 wineries and vineyards in operation in the Waitaki valley. The town was the terminus of t ...

Rotating Black Hole
A rotating black hole is a black hole that possesses angular momentum. In particular, it rotates about one of its axes of symmetry. All celestial objects – planets, stars (Sun), galaxies, black holes – spin. Types of black holes There are four known, exact, black hole solutions to the Einstein field equations, which describe gravity in general relativity. Two of those rotate: the Kerr and Kerr–Newman black holes. It is generally believed that every black hole decays rapidly to a stable black hole; and, by the no-hair theorem, that (except for quantum fluctuations) stable black holes can be completely described at any moment in time by these 11 numbers: * mass-energy ''M'', * linear momentum ''P'' (three components), * angular momentum ''J'' (three components), * position ''X'' (three components), * electric charge ''Q''. These numbers represent the conserved attributes of an object which can be determined from a distance by examining its electromagnetic and gravitat ...

Alfred Schild
Alfred Schild (September 7, 1921 – May 24, 1977) was a leading Austrian American physicist, well known for his contributions to the Golden age of general relativity (1960–1975). Biography Schild was born in Istanbul on September 7, 1921. His parents were German-speaking Viennese Jews, but his early education was in England. Upon the outbreak of World War II Schild was interned as an enemy alien, but later allowed to travel to Canada. In 1944 he earned his B.A. at the University of Toronto, and in 1946 completed his doctorate under the direction of Leopold Infeld. Schild spent the next eleven years at the Carnegie Institute of Technology, where he helped to develop the first atomic clocks. As tensors are the language of general relativity, Schild wrote ''Tensor Calculus'' with John L. Synge as a textbook. According to a reviewer, "The ideas and concepts are given very concisely and thus a wide range of subjects is considered." In 1957 he moved to the University of Texas at Au ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ...

Peter Bergmann
Peter Gabriel Bergmann (24 March 1915 – 19 October 2002) was a German-American physicist best known for his work with Albert Einstein on a unified field theory encompassing all physical interactions. He also introduced primary and secondary constraints into mechanics. Early life and education Bergmann was born into a Jewish family of Max Bergmann, a biochemistry professor and Emmy Bergmann, a pediatrician in Berlin. His father would later be a professor of chemistry at the Rockefeller Institute for Medical Research. He began college in 1931, at the age of 16, at ''Technische Hochschule'' (now TU Dresden) under the mentorship of Harry Dember. Bergmann obtained his PhD at the age of 21 from the German University in Prague in 1936 under the direction of Philipp Frank. Bergmann's family scattered all over the world during Nazi rule; his sister Clara stayed behind and ultimately was murdered at Auschwitz. Career Bergmann's association with Einstein began without his knowled ...

Postdoctoral Researcher
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ...

St Andrew's College, Christchurch
St Andrew's College, also known as StAC, in Christchurch, New Zealand, is a private, co-educational school that enrols from pre-school to secondary Year 13. It was founded in 1917 and it is the only independent, co-educational primary and secondary school in New Zealand's South Island. Although now a fully co-educational school, it was formerly an all-boys school. It became fully co-educational in 2001. The current rector of St Andrew's College is Christine Leighton. History St Andrew's College was founded by Rev. Alexander Thomas Thompson in 1917 in the Scottish Presbyterian tradition of the Christian faith. The school began in a humble fashion with 19 boys and four teachers, driven by the determination of the Reverend Thompson, whose driving ambition was to ‘educate the sons of the Presbyterian and Scottish community of Canterbury.’ StAC had three boarding houses for the 165 boarders of years 9 to 13: MacGibbon (years 9 to 11) and Rutherford (years 11 to 13) for boys, ...
