Paris: Gauthier-Villers, et fils, 1895. 8vo. Pages 289-405. FIRST EDITION. Original printed wrappers; a fine copy, uncut and unopened. Item #13232
The first printing following the author's defense of his thesis on 6 March 1895 presented to the Faculty of Science, University of Paris, for the degree of Docteur dés Sciences Physiques. Curie devoted a great deal of effort to studying the magnetic properties of substances at various temperatures, at the time one of the most obscure areas of physics. The results form the basis of all modern theories of magnetism. The Curie point is the temperature above which the material loses its characteristic ferromagnet properties. He discovered paramagnetism to be inversely proportional to the absolute temperature, a phenomenon now known as "Curie's Law."
Pierre Cure (1859-1906) was a renowned physicist who made original contributions in many disciplines. With his wife Marie Curie and Henri Becquerel he received the Nobel Prize in Physics in 1903.
