Lars Vegard
Lars Vegard (3 February 1880 – 21 December 1963) was a Norwegian physicist who is a pioneer in crystallography. He also made contributions to materials science and the science of aurora borealis. The Vegard's law in solid state chemistry and materials science, the only law of nature formulated by a Norwegian, is named after him. Education and scientific career He was born in Vegårshei as a son of farmer Nils Gundersen Grasaasen (1840–1886) and Anne Grundesdatter Espeland (1839–1930). He attended middle school in Risør and took the examen artium in Kristiania in 1899. He enrolled at the Royal Frederick University (now University of Oslo) and graduated with the cand.real. degree in 1905. From 1906, Vegard worked as an assistant under Kristian Birkeland. He studied under J. J. Thomson from 1908 to 1910 and under Wilhelm Wien from 1911 to 1912. He was a research fellow in physics from 1908 to 1910 and ''amanuensis'' from 1910 to 1913, both at the Royal Frederick University. ...

Royal Frederick University
The University of Oslo ( no, Universitetet i Oslo; la, Universitas Osloensis) is a public research university located in Oslo, Norway. It is the highest ranked and oldest university in Norway. It is consistently ranked among the top universities in the world and as one of the leading universities of Northern Europe; the Academic Ranking of World Universities ranked it the 58th best university in the world and the third best in the Nordic countries. In 2016, the Times Higher Education World University Rankings listed the university at 63rd, making it the highest ranked Norwegian university. Originally named the Royal Frederick University, the university was established in 1811 as the de facto Norwegian continuation of Denmark-Norway's common university, the University of Copenhagen, with which it shares many traditions. It was named for King Frederick VI of Denmark and Norway, and received its current name in 1939. The university was commonly nicknamed "The Royal Frederick's" ...

Aker, Norway
Aker was a former independent municipality in Akershus, Norway, that constitutes the vast majority of the territory of the modern city of Oslo. The name originally belonged to a farm which was located near the current Old Aker Church. The church in turn became the source of the name of the parish and later municipality as well as Akershus Fortress, the main fief and main county of Akershus which included most of Eastern Norway until 1919, the smaller county of Akershus, and numerous institutions within this area. Aker municipality was in terms of population by far the largest municipality of Akershus county and surrounded the capital city of Christiania (renamed Oslo in 1925) until 1948; Aker was 27 times larger than the capital it surrounded. In the late 19th century Aker ceded some of its territory to Christiania, and in 1948 Aker merged completely with Oslo municipality to create the modern, vastly enlarged Oslo municipality. The merger was unpopular in Aker, which at the time ...

Liberal Party Of Norway
The Liberal Party ( no, Venstre, lit=Left, V; se, Gurutbellodat) is a centrist political party in Norway. It was founded in 1884 and it is the oldest political party in Norway. It is positioned in the centre on the political spectrum, and it is a liberal party which has over the time enacted reforms such as parliamentarism, freedom of religion, universal suffrage, and state schooling. For most of the late 19th and early 20th century, it was Norway's largest and dominant political party, but in the postwar era it lost most of its support and became a relatively small party. The party has nevertheless participated in several centrist and centre-right government coalitions in the postwar era. It currently holds eight seats in the Parliament, and was previously a part of Norway's government together with the Conservative Party and the Christian Democratic Party. Guri Melby has served as the party leader since 2020. The party is regarded as social-liberal and advocates personal freed ...

Norwegian Academy Of Science And Letters
The Norwegian Academy of Science and Letters ( no, Det Norske Videnskaps-Akademi, DNVA) is a learned society based in Oslo, Norway. Its purpose is to support the advancement of science and scholarship in Norway. History The Royal Frederick University in Christiania was established in 1811. The idea of a learned society in Christiania surfaced for the first time in 1841. The city of Trondhjem had no university, but had a learned society, the Royal Norwegian Society of Sciences and Letters, established in 1760. The purpose of a learned society in Christiania was to support scientific studies and aid publication of academic papers. The idea of the Humboldt-inspired university, where independent research stood strong, had taken over for the instrumental view of a university as a means to produce civil servants. The city already had societies for specific professions, for instance the Norwegian Medical Society which was founded in 1833. However, these societies were open for both acad ...

Hydrogen Line
The hydrogen line, 21 centimeter line, or H I line is the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This electromagnetic radiation has a precise frequency of , which is equivalent to the vacuum wavelength of in free space. This frequency falls below the microwave region of the electromagnetic spectrum, which begins at 3.0 GHz (10 cm wavelength), and it is observed frequently in radio astronomy because those radio waves can penetrate the large clouds of interstellar cosmic dust that are opaque to visible light. This line is also the theoretical basis of the hydrogen maser. The microwaves of the hydrogen line come from the atomic transition of an electron between the two hyperfine levels of the hydrogen 1 s ground state that have an energy difference of []. It is called the ''spin-flip transition''. The frequency, , of the quantum, quanta that are emitted by this transition between tw ...

Doppler Effect
The Doppler effect or Doppler shift (or simply Doppler, when in context) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession. The reason for the Doppler effect is that when the source of the waves is moving towards the observer, each successive wave crest is emitted from a position closer to the observer than the crest of the previous wave. Therefore, each wave takes slightly less time to reach the observer than the previous wave. Hence, the time between the arrivals of successive wave crests at the observer is reduced, causing an increa ...

Hydrogen Emission
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 yea ...
