Gustav Heinrich Johann Apollon Tammann
Gustav Heinrich Johann Apollon Tammann ( – 17 December 1938) was a prominent Baltic German chemist-physicist who made important contributions in the fields of glassy and solid solutions, heterogeneous equilibria, crystallization, and metallurgy. Biography Tamman was born in Yamburg (now Kingisepp, Leningrad Oblast). His father, Heinrich Tammann (1833–1864) was of Estonian peasant origin and his mother, Matilda Schünmann, was of German origin. Tamman graduated from University of Dorpat in chemistry. He came to Göttingen University in 1903 where he established the first Institute of Inorganic Chemistry in Germany. In 1908 he was appointed director of the Physico-Chemical Institute. His interests focused on the physics and physical chemistry of metals and alloys ( metallurgy). In 1925 Tammann was awarded Liebig Medal. On 28 May 1936, Tammann was awarded the shield of nobility of the German Empire (), with dedication "The Doyen of German Metallurgy". He also known for th ...

Kingisepp
Kingisepp (russian: Ки́нгисепп or ), formerly Yamburg (), Yam (), and Yama (; Votic: ), is an ancient town and the administrative center of Kingiseppsky District of Leningrad Oblast, Russia, located along the Luga River southwest of St. Petersburg, east of Narva, and south of the Gulf of Finland. Population: History 14th century The town was first documented in 1384, when the Novgorodians under Patrikas built there a fortress against the Swedes. It was called Yama or Yamsky Gorodok, after the Izhorian (ethnic Finnic group) name Jaama. The environs of the town are still cited as the main location of speakers of the nearly extinct Izhorian language. The citadel withstood sieges by the Swedes in 1395 and by the Teutonic Knights during the 1444–1448 war. 15-16th century The town became the most important economic center of the of the Novgorod Republic. There were 201 homesteads in the 15th century in the town; its total population can only be evalua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include m ...

State Of Matter
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates (in extreme cold), neutron-degenerate matter (in extreme density), and quark–gluon plasma (at extremely high energy). For a complete list of all exotic states of matter, see the list of states of matter. Historically, the distinction is made based on qualitative differences in properties. Matter in the solid state maintains a fixed volume (assuming no change in temperature or air pressure) and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume (assuming no change in temperature or air pressure), but has a variable shape that adapts to fit its container ...

Tartu University
The University of Tartu (UT; et, Tartu Ülikool; la, Universitas Tartuensis) is a university in the city of Tartu in Estonia. It is the national university of Estonia. It is the only classical university in the country, and also its biggest and most prestigious university. It was founded under the name of ''Academia Gustaviana'' in 1632 by Baron Johan Skytte, the Governor-General (1629–1634) of Swedish Livonia, Ingria, and Karelia, with the required ratification provided by his long-time friend and former student – from age 7 –, King Gustavus Adolphus, shortly before the king's death on 6 November in the Battle of Lützen (1632), during the Thirty Years' War (1618–1648). Nearly 14,000 students are at the university, of whom over 1,300 are foreign students. The language of instruction in most curricula is Estonian, some more notable exceptions are taught in English, such as semiotics, applied measurement science, computer science, information technology law, and Europe ...

Tait Equation
In fluid mechanics, the Tait equation is an equation of state, used to relate liquid density to hydrostatic pressure. The equation was originally published by Peter Guthrie Tait in 1888 in the form : \frac = \frac where P is the hydrostatic pressure in addition to the atmospheric one, V_0 is the volume at atmospheric pressure, V is the volume under additional pressure P, and A, \Pi are experimentally determined parameters. A very detailed historical study on the Tait equation with the physical interpretation of the two parameters A and \Pi is given in reference. Tait-Tammann equation of state In 1895, the original isothermal Tait equation was replaced by Tammann with an equation of the form : = - \left ( \frac \right )_T = \frac where K is the isothermal mixed bulk modulus. This above equation is popularly known as the Tait equation. The integrated form is commonly written : V = V_0 - C \log \left(\frac\right) where * V \ is the specific volume of the substance ...

Adlerschild Des Deutschen Reiches
The ''Adlerschild des Deutschen Reiches'' ( en, Eagle Shield of the German Reich) was an honorary award (german: Ehrengabe) granted by the German president for scholarly or artistic achievements. It was introduced during the Weimar Republic, under President Friedrich Ebert and continued under Nazi Germany. It was a metal disc with a German imperial eagle on a pedestal. It was a high and infrequently awarded honor, received by around 70 people in total. Recipients during the Weimar Republic Article 109, section 3 of the Weimar Constitution entitled "Orders and honours may not be given by the state" enacted a ban on honorific orders. Nevertheless, there was a desire for the state to be able to confer symbolic honours and the honorific award of the Adlerschild des Deutschen Reiches was created to meet this desire. It consisted of a 108 mm wide medal of cast bronze, mounted on a bronze pedestal and inscribed on the reverse with an individualised honorific inscription. The desig ...

Alloys
An alloy is a mixture of chemical elements of which at least one is a metal. Unlike chemical compounds with metallic bases, an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opacity, and luster, but may have properties that differ from those of the pure metals, such as increased strength or hardness. In some cases, an alloy may reduce the overall cost of the material while preserving important properties. In other cases, the mixture imparts synergistic properties to the constituent metal elements such as corrosion resistance or mechanical strength. Alloys are defined by a metallic bonding character. The alloy constituents are usually measured by mass percentage for practical applications, and in atomic fraction for basic science studies. Alloys are usually classified as substitutional or interstitial alloys, depending on the atomic arrangement that forms the alloy. They can be further classified as homog ...

Göttingen University
Göttingen (, , ; nds, Chöttingen) is a university city in Lower Saxony, central Germany, the capital of the eponymous district. The River Leine runs through it. At the end of 2019, the population was 118,911. General information The origins of Göttingen lay in a village called ''Gutingi, ''first mentioned in a document in 953 AD. The city was founded northwest of this village, between 1150 and 1200 AD, and adopted its name. In medieval times the city was a member of the Hanseatic League and hence a wealthy town. Today, Göttingen is famous for its old university (''Georgia Augusta'', or "Georg-August-Universität"), which was founded in 1734 (first classes in 1737) and became the most visited university of Europe. In 1837, seven professors protested against the absolute sovereignty of the kings of Hanover; they lost their positions, but became known as the "Göttingen Seven". Its alumni include some well-known historical figures: the Brothers Grimm, Heinrich Ewal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
