See also:ARRHENIUS, SVANTE See also:AUGUST (1859– ) , See also:Swedish physicist and chemist, was See also:born on the 19th of See also:February 1859, at Schloss Wijk, near See also:Upsala. He studied at Upsala from 1876 to 1881 and at See also:Stockholm from 1881 to 1884, then returning to Upsala as privat-docent in See also:physical See also:chemistry. He spent two years from 1886 to 1888 in travelling, and visited See also:Riga Poly-technic and the See also:universities of Wtirzburg, See also:Graz, See also:Amsterdam and See also:Leipzig. In 1891 he was appointed lecturer in physics at Stockholm and four years later became full See also:professor. Arrhenius is specially associated with the development of the theory of electrolytic See also:dissociation, and his See also:great See also:paper on the subject, Recherches sur la conductibilite galvanique See also:des electrolytes—(1) conductibilite galvanique des solutions aqueuses extremement diluees, (2) theorie chimique des electrolytes, was presented to the Stockholm See also:Academy of Sciences in 1883. He was subsequently continuously engaged in extending the applications of the See also:doctrine of electrolytic See also:conduction in relation not only to the problems of chemical See also:action but also, on the supposition that in certain conditions the See also:air conducts electrolytically, to the phenomena of atmospheric See also:electricity. In 1900 he published a Leirobok i teoretik elektrokemi, which was translated into See also:German and See also:English, and his Lehrbuch der kosmischen Physik appeared in 1903. In 1904 he delivered at the university of See also:California a course of lectures, the See also:object of which was to illustrate the application of the methods of physical chemistry to the study of the theory of toxins and antitoxins, and which were published in 1907 under the See also:title Immunochemistry. In his Worlds in the Making (1908), an English See also:translation of Das See also:Werden der Welten (1907), he combated the generally accepted doctrine that the universe is tending to what See also:Clausius termed Wdrmetod through exhaustion of all See also:sources of See also:heat and See also:motion, and suggested that by virtue of a mechanism which maintains its available See also:energy it is self-renovating, energy being " degraded " in bodies which are in the See also:solar See also:state, but " elevated " or raised to a higher level in bodies which are in the nebular state. He further put forward the conception that See also:life is universally diffused, constantly ' The name Cilnius was apparently never See also:borne by See also:Maecenas himself, though he is so described, e.g. by See also:Tacitus, See also:Ann. vi. II, cf. Macrob. ii. 4, 12. The Cilnii with whom Maecenas was connected were a See also:noble See also:Etruscan See also:family.emitted from all habitable worlds in the See also:form of spores which See also:traverse space for years or ages, the See also:majority being ultimately destroyed by the heat of some blazing See also:star, but some few finding a resting-See also:place on bodies which have reached the habitable See also:stage.
