Johan Gadolin
Johan Gadolin (5 June 176015 August 1852) was a Finnish chemist, physicist and mineralogist. Gadolin discovered a " new earth" containing the first rare-earth compound yttrium, which was later determined to be a chemical element. He is also considered the founder of Finnish chemistry research, as the second holder of the Chair of Chemistry at the Royal Academy of Turku (or ''Åbo Kungliga Akademi''). Gadolin was ennobled for his achievements and awarded the Order of Saint Vladimir and the Order of Saint Anna. Early life and education Johan Gadolin was born in Åbo (Finnish name Turku), Finland (then a part of Sweden). Johan was the son of Jakob Gadolin, professor of physics and theology at Åbo. Johan began to study mathematics at the Royal Academy of Turku (''Åbo Kungliga Akademi'') when he was fifteen. Later he changed his major to chemistry, studying with Pehr Adrian Gadd, the first chair of chemistry at Åbo. In 1779 Gadolin moved to Uppsala University. In 1781, ...

Turku
Turku ( ; ; sv, Åbo, ) is a city and former capital on the southwest coast of Finland at the mouth of the Aura River, in the region of Finland Proper (''Varsinais-Suomi'') and the former Turku and Pori Province (''Turun ja Porin lääni''; 1634–1997). The region was originally called Suomi (Finland), which later became the name for the whole country. As of 31 March 2021, the population of Turku was 194,244 making it the sixth largest city in Finland after Helsinki, Espoo, Tampere, Vantaa and Oulu. There were 281,108 inhabitants living in the Turku Central Locality, ranking it as the third largest urban area in Finland after the Capital Region area and Tampere Central Locality. The city is officially bilingual as percent of its population identify Swedish as a mother-tongue. It is unknown when Turku gained city rights. The Pope Gregory IX first mentioned the town ''Aboa'' in his ''Bulla'' in 1229 and the year is now used as the foundation year of Turku. Turku ...

Royal Academy Of Turku
The Royal Academy of Turku or the Royal Academy of Åbo ( sv, Kungliga Akademin i Åbo or ; la, Regia Academia Aboensis; fi, Turun akatemia) was the first university in Finland, and the only Finnish university that was founded when the country still was a part of Sweden. It was founded in 1640. In 1809, after Finland became a Grand Duchy under the suzerainty of the Russian czar, it was renamed the ''Imperial Academy of Turku''. In 1828, after the Great Fire of Turku, the institution was moved to Helsinki, in line with the relocation of the Grand Duchy's capital. It was finally renamed the University of Helsinki when Finland became a sovereign nation-state in 1917. History The academy was founded on 26 March 1640 by Queen Christina of Sweden at the proposal of Count Per Brahe, on base of Åbo Cathedral School (founded 1276). It was the third university in the Swedish Empire, following Uppsala University (founded 1477) and the Academia Gustaviana (now the University of Tar ...

Adair Crawford
Adair Crawford FRS FRSE (174829 July 1795), a chemist and physician, was a pioneer in the development of calorimetric methods for measuring the specific heat capacity of substances and the heat of chemical reactions. In his influential 1779 book "''Experiments and Observations on Animal Heat''", Crawford presented new experiments proving that respiratory gas exchange in animals is a combustion (two years after Antoine Lavoisier's influential "''On combustion in general''"). Crawford also was involved in the discovery of the element strontium. Life Adair Crawford was born in Crumlin, Belfast, the son of Rev Thomas Crawford. He studied medicine at Glasgow and Edinburgh universities. He qualified MA in 1770 and then worked at St George's Hospital in London before qualifying MD in 1780. He was Professor of Chemistry at the Royal Military Academy, Woolwich, London, and physician at St Thomas' Hospital, London. He died at Lymington in Hampshire. It is no coincidence that the tit ...

Carl Wilhelm Scheele
Carl Wilhelm Scheele (, ; 9 December 1742 – 21 May 1786) was a Swedish German pharmaceutical chemist. Scheele discovered oxygen (although Joseph Priestley published his findings first), and identified molybdenum, tungsten, barium, hydrogen, and chlorine, among others. Scheele discovered organic acids tartaric, oxalic, uric, lactic, and citric, as well as hydrofluoric, hydrocyanic, and arsenic acids. He preferred speaking German to Swedish his whole life, as German was commonly spoken among Swedish pharmacists.Fors, Hjalmar 2008. Stepping through Science’s Door: C. W.

Johan Gottlieb Gahn
Johan Gottlieb Gahn (19 August 1745 – 8 December 1818) was a Swedish chemist and metallurgist who isolated manganese in 1774. Gahn studied in Uppsala 1762 – 1770 and became acquainted with chemists Torbern Bergman and Carl Wilhelm Scheele. 1770 he settled in Falun, where he introduced improvements in copper smelting, and participated in building up several factories, including those for vitriol, sulfur and red paint. He was the chemist for The Swedish Board of Mines '' Bergskollegium'' from 1773 – 1817. Gahn was however very reluctant to publish his scientific findings himself, but freely communicated them to Bergman and Scheele. One of Gahn's discoveries was that manganese dioxide could be reduced to manganese metal using carbon, becoming the first to isolate this element in its metal form. In 1784, Gahn was elected a member of the Royal Swedish Academy of Sciences. He also made a managerial career in Swedish mining. See also * Gahnite Gahnite, ZnAl2O4, is a rare minera ...

Torbern Bergman
Torbern Olaf (Olof) Bergman (''KVO'') (20 March 17358 July 1784) was a Swedish chemist and mineralogist noted for his 1775 ''Dissertation on Elective Attractions'', containing the largest chemical affinity tables ever published. Bergman was the first chemist to use the A, B, C, etc., system of notation for chemical species. Early life and education Torbern was born on 20 March 1735, the son of Barthold Bergman and Sara Hägg. He enrolled at the University of Uppsala at age 17. His father wished him to read either law or divinity, while he himself was anxious to study mathematics and natural science; in the effort to please both himself and his father, he overworked himself and harmed his health. During a period of enforced abstinence from study, he amused himself with field botany and entomology. He was able to send Linnaeus specimens of several new kinds of insects, and in 1756 he succeeded in proving that, contrary to the opinion of that naturalist, the so-called ''Coccus aqu ...

Uppsala University
Uppsala University ( sv, Uppsala universitet) is a public research university in Uppsala, Sweden. Founded in 1477, it is the oldest university in Sweden and the Nordic countries still in operation. The university rose to significance during the rise of Sweden as a great power at the end of the 16th century and was then given a relative financial stability with a large donation from King Gustavus Adolphus in the early 17th century. Uppsala also has an important historical place in Swedish national culture, identity and for the Swedish establishment: in historiography, literature, politics, and music. Many aspects of Swedish academic culture in general, such as the white student cap, originated in Uppsala. It shares some peculiarities, such as the student nation system, with Lund University and the University of Helsinki. Uppsala belongs to the Coimbra Group of European universities and to the Guild of European Research-Intensive Universities. It has ranked among the world' ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of t ...
