Максвелл Джеймс Клёрк - Трактат по электричеству и магнетизму. Том 1 - Издание второе, переработанное. (англ. яз. )
Работа Д. К. Максвелла (1831-1879) об электричестве и магнетизме впервые была издана в 1873 г. Она содержит созданную Максвеллом теорию электрических и магнитных явлений. Эта теория в настоящее время составляет фундамент современного естествознания. По своему значению для развития науки «Трактат» стоит в одном ряду с «Началами» Ньютона и «Экспериментальными исследованиями» Фарадея.
PREFACE TO THE SECOND EDITION
WHEN I was asked to read the proof-sheets of the second edition of the Electricity and Magnetism the work of printing had l ready reached the ninth chapter, the greater part of which had been revised by the author. Those who are familiar with the first edition will see from a comparison with the present how extensive were the changes intended by Professor Maxwell both in the substance and in the treatment of the subject, and how much this edition has suffered from his premature death. The first nine chapters were in some cases entirely rewritten, much new matter being added and the former contents rearranged and simplified.
From the ninth chapter onwards the present edition is little more than a reprint. The only liberties I have taken have been in the insertion here and there of a step in the mathematical reasoning where it seemed to be an advantage to the reader, and of a few foot-notes on parts of the subject which my own experience or that of pupils attending my classes shewed to require further elucidation. These footnotes are in square brackets.There were two parts of the subject in the treatment of which it was known to me that the Professor contemplated considerable changes : viz. the mathematical theory of the conduction of electricity in a network of wires, and the determination of coefficients of induction in coils of wire. In these subjects I have not found myself in a position to add, from the Professor s notes, anything substantial to the work as it stood in the former edition, with the exception of a numerical table, printed in vol. ii, pp. 317-
319. This table will be found very useful in calculating coefficients of induction in circular coils of wire. In a work so original, and containing so many details of new results, it was impossible but that there should be a few errors in the first edition. I trust that in the present edition most of these will be found to have been corrected. I have the greater confidence in expressing this hope as, in reading some of the proofs, I have had the assistance of various friends conversant with the work, among whom I may mention particularly my brother Professor Charles Niven, and Mr. J. J. Thomson, Fellow of Trinity College, Cambridge.
