The book covers a very wide area of physIcs in what the authors call an aUmpt "to acquaint the reader with the principal phenomena and most important laws of physics". However this acquaintance can hardly be deep or critical for the book of 372 pages has somethmg to say about a rather wide vanety of topics. Naturally enough oDe misses very often a discussion or mathematical treatment which can in any sense be called complete. Yet if anybody hkes to have an idea of say classical mechanic-ii, classical field theory, the crystalline symmetry and lattices, the kinetic theory, the laws and approach of thermodynamics, the electrol~tes, chemical reactions and surface phenomena, transport properties) plasticity and elastidty, and '\Ilseosny (well, here there are II. few pages on supcrftuldity even) in one smgle sman volume then here is that unique combmatlon and he Will also ha'\lc a flavour of the lucldity, and orIginality which has characterised the now famous series of texts by Landau and Lifshitz. ThiS book Wilt not serve as a text book for any course in our universities but will be a pleasant reading Qutstudy book for undergraduate sludents In Physics and Chemistry and will help in clanfyinB thclC Ideas,
The magnetic susceptibility of copper, silver, platinum and bismuth was measured for the annealed state and after various degrees of cold work. The cold work consisted of twisting, stretching and pounding. In every case the cold work decreased the diamagnetism (Cu, Ag, Bi), or increased the paramagnetism (Pt). This probably explains the variation in the measured values of metallic susceptibilities as due to a structure sensitiveness. This is attributed to the increase in the paramagnetic contribution of the partly bound electrons of the metal due to the cold work; the electrical conductivity is usually decreased.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
