See also:HANSTEEN, See also:CHRISTOPHER (1784–1873) , See also:Norwegian astronomer and physicist, was See also:born at See also:Christiania, on the 26th of See also:September 1784. From the See also:cathedral school he went to the university at See also:Copenhagen, where first See also:law and afterwards See also:mathematics formed his See also:main study. In 18o6 he taught mathematics in the gymnasium of Frederiksborg, See also:Zeeland, and in the following See also:year he began the inquiries in terrestrial See also:magnetism with which his name is especially associated. He took in 181a the See also:prize of the Danish Royal See also:Academy of Sciences for his reply to a question on the magnetic axes. Appointed lecturer in 1814, he was in 1816 raised to the See also:chair of See also:astronomy and applied mathematics in the university of Christiania. In 1819 he published a See also:volume of researches on terrestrial magnetism, which was translated into See also:German by P. T. See also:Hanson, under the See also:title of Untersuchungen fiber den Magnetismus der Erde, with a supplement containing Beobachtungen der Abweichung and Neigung der Magnelnadel and an See also:atlas. By the rules there framed for the observation of magnetical phenomena Hansteen hoped to accumulate analyses for determining the number and position of the magnetic poles of the See also:earth. In See also:prosecution of his researches he travelled over See also:Finland and the greater See also:part of his own See also:country; and in 1828–183o he undertook, in See also:company with G. A. See also:Erman, and with the co-operation of See also:Russia, a See also:government See also:mission to Western See also:Siberia. A narrative of the expedition soon appeared (Reise-Erinnerungen aus Sibirien, 1854; Souvenirs See also:HAPARANDA 932 d' un voyage en Siberie, 1857); but the See also:chief See also:work was not issued till 1863 (Resultate magnetischer Beobachtungen, &c.). Shortly after the return of the mission, an See also:observatory was erected in the See also:park of Christiania (1833), and,Hansteen was appointed director. On his ,See also:representation a magnetic observatory was added in 1839: In 1835—1838 he published See also:text-books on See also:geometry and See also:mechanics; and in 1842 he wrote his Disquisitiones de mutatlensbus quas patitur momentum aces magneticae, &c. He alsei ontributed various papers to different scientific See also:journals, especially the Magazin for Naturvidenskaberne, of which he betable See also:joint-editor in 1823. He superintended the trigonometrical and topographical survey of See also:Norway, begun in 1837. In 1861 he retired from active work, but still pursued his studies, his Observations de l'inclination magnetique and Sur See also:les See also:variations seculaires du magnetisme appearing in 1865. He died at Christiania on the 11th of See also:April 1873. Additional information and CommentsThere are no comments yet for this article.
