…In 1829, he became professor of mineralogy and physics at the University of Königsberg, where he studied the specific heat of minerals and birefringence in crystals and amorphous materials. In 1831, together with Hermann Franz Moritz Kopp (1817-92), he discovered the Neumann–Kopf law, which states that the molar specific heat of a solid is approximately equal to the sum of the atomic heats (heat capacity per gram of atom) of its component elements. In 1845, he mathematically formulated the law of induced currents based on Lenz's law and derived Neumann's law. … *Some of the terminology referenced in "Kopp, HFM" is listed below.

…29年にケーニヒスベルクの大学で鉱物学と物理学の教授となり,鉱物の比熱の研究や,結晶中や非晶質中での複屈折の研究を行った。31年,コップHermann Franz Moritz Kopp(1817‐92)とともに固体のモル比熱が近似的に成分元素の原子熱(1グラム原子に対する熱容量)の和に等しいというノイマン=コップの法則を見いだした。45年には,レンツの法則に基づいて誘導電流の法則を数学的に定式化し,ノイマンの法則を導出した。… ※「Kopp,H.F.M.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
