Gunnar Källén
Anders Olof Gunnar Källén (13 February 1926 – 13 October 1968) was a Swedish theoretical physicist and professor at Lund University, known for his work on correlation functions in quantum field theory. He died at the age of 42 as a result of a plane crash. Biography Anders Olof Gunnar Källén was born in 1926 in Kristianstad, Sweden. His father, Yngve Källén, was a teacher of physics and mathematics, and together they published a paper on the theory of relativity. Gunnar's brother was the embryologist . Källén earned his doctorate at Lund in 1950 working with Torsten Gustafson, who was in close correspondence with Wolfgang Pauli. He worked at CERN's theoretical division from 1952 to 1957, which, at that time, was situated at the Institute for Theoretical Physics of the University of Copenhagen, later to be named Niels Bohr Institute.

Kristianstad
Kristianstad ( , ) is a Urban areas in Sweden, city and the seat of Kristianstad Municipality, Scania County, Sweden with 41,198 inhabitants in 2023. Since the 1990s, the city has gone from being a garrison town to a developed commercial city, focusing on nature preservation and a food profile. History The city was founded in 1614 by King Christian IV of Denmark (the city's name literally means 'Town of Christian'or "Christian's town") as a planned city after the burning of the nearby town of Vä and moving the city rights of the neighbouring town of Vå and Åhus to the new town. The purpose of the town was to safeguard the eastern half of the Danish province of Scania against any future raids from Sweden in the north, but also as a symbol of the power of Christian himself. One of these raids had sacked the nearby town of Vä in 1612. Vä then lost its charter and the people were relocated to the new, better fortified city. The king also founded the town of Kristianopel in ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niels Bohr Institute
The Niels Bohr Institute () is a research institute of the University of Copenhagen. The research of the institute spans astronomy, geophysics, nanotechnology, particle physics, quantum mechanics, and biophysics. Overview The institute was founded in 1921, as the Institute for Theoretical Physics of the University of Copenhagen, by the Danish theoretical physicist Niels Bohr, who had been on the staff of the University of Copenhagen since 1914, and who had been lobbying for its creation since his appointment as professor in 1916. On the 80th anniversary of Niels Bohr's birth – October 7, 1965 – the Institute officially became the Niels Bohr Institute. Much of its original funding came from the charitable foundation of the Carlsberg Group, Carlsberg brewery, and later from the Rockefeller Foundation. During the 1920s, and 1930s, the institute was the center of the developing disciplines of atomic physics and quantum physics. Physicists from across Europe (and sometimes furthe ...

1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Cecilia Jarlskog
Cecilia Jarlskog (born in 1941) is a Swedish theoretical physicist, working mainly on elementary particle physics. Jarlskog obtained her doctorate in 1970 in theoretical particle physics at the Technical University of Lund. She is known for her work on CP violation in the electroweak sector of the Standard Model, introducing what is known as the Jarlskog invariant, and for her work on grand unified theories (see Georgi–Jarlskog mass relation). Research interests Cecilia Jarlskog is mainly known for her study and expertise in theoretical particle physics. Her studies include research on the ways that sub-atomic and electronic constituents of matter cohere or lose their symmetry, matter and antimatter asymmetry, mathematical physics, neutrino physics, and grand unification. The Jarlskog invariant or rephasing-invariant CP violation parameter, is an invariant quantity in particle physics, which is in the order of ±2.8 x 10−5.

Emergency Landing
An emergency landing is a premature landing made by an aircraft in response to an emergency involving an imminent or ongoing threat to the safety and operation of the aircraft, or involving a sudden need for a passenger or crew on board to terminate the flight (such as a medical emergency). It typically involves a forced diversion to the nearest or most suitable airport or airbase, or an forced landing, off airport landing or ditching if the flight cannot reach an airfield. Flights under air traffic control will be given priority over all other aircraft operations upon the declaration of the emergency. Types There are several different types of emergency landings for powered aircraft: planned landing or unplanned landing. * ''Forced landing'' – the aircraft is forced to make a landing due to technical problems. Landing as soon as possible is a priority, no matter where, since a major system failure has occurred or is imminent. It is caused by the failure of or damage to vital ...
