Gunnar Nordström

Gunnar Nordström (12 March 1881, Helsinki – 24 December 1923, Helsinki) was a Finnish theoretical physicist who is best remembered for his theory of gravitation, which was an early competitor of general relativity. Events 538 - Witiges, king of the Ostrogoths ends his siege of Rome and retreats to Ravenna, leaving Year 1881 ( MDCCCLXXXI) was a Common year starting on Saturday (link will display the full calendar of the Gregorian calendar (or a Common Helsinki (in Finnish;) or Helsingfors (in Swedish;) is the Capital and largest city of Finland. Events 563 - The Byzantine church Hagia Sophia in Constantinople is dedicated for the second time after being destroyed by Earthquakes Year 1923 ( MCMXXIII) was a Common year starting on Monday (link will display the full calendar of the Gregorian calendar. Finland, officially the Republic of Finland ( is a Nordic country situated in the Fennoscandian region of northern Europe. Gravitation is a natural Phenomenon by which objects with Mass attract one another General relativity or the general theory of relativity is the geometric theory of Gravitation published by Albert Einstein in 1916

Nordström completed his dissertation at the University of Helsinki in 1908, became a docent at the university, later worked for a couple of years in Leiden with Paul Ehrenfest, and became professor at the Helsinki University of Technology in 1918.

In 1914 Nordström introduced an additional space dimension to his theory, which simultaneously described gravity and electromagnetism. Electromagnetism is the Physics of the Electromagnetic field: a field which exerts a Force on particles that possess the property of This was the first of extra dimensional theories, later known as Kaluza-Klein theory. String theory is a still-developing scientific approach to Theoretical physics, whose original building blocks are one-dimensional extended objects called strings In Physics, Kaluza–Klein theory (or KK theory, for short is a model that seeks to unify the two fundamental forces of Gravitation and

During the time in Leiden Nordström solved the field equations for the spherically symmetric charged body, thus extending the Hans Reissner's results for a point charge. The metric for a nonrotating charge distribution is nowadays known as Reissner-Nordström metric. In Physics and Astronomy, the Reissner-Nordström metric is a solution to the Einstein field equations in empty space which corresponds to the gravitational

Nordström died in December 1923 at the age of 42, possibly from exposure to radioactive substances. Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation.
