The most influential Scottish scientist of the 19th century in Physics, James Clerk Maxwell (1831–1879) was a pioneer of science, demonstrating that electricity, magnetism, and light are all manifestations of the same phenomenon: the electromagnetic field. This book is a re-print of the original 1st edition (1873) of the 2nd volume, an important foundation work on modern physics, a must-have for all mathematicians and physicists for their libraries. THE VERSION OF THE BOOK PUBLISHED BY AKAKIA PUBLICATIONS CONTAINS THE ORIGINAL TABLE OF CONTENTS, ALL EQUATIONS, AND ALL DIAGRAMS ILLUSTRATED BY JAMES CLERK MAXWELL. Describes electrostatic phenomena and develops a mathematical theory of electricity. Topics include electrical work and energy in a system of conductors, mechanical action between two electrical systems, spherical harmonics, electric current, conduction and resistance, electrolysis, and other subjects, with illustrations and the original “plates” Maxwell draw. This book is a re-print of the 1st edition and it is the original work photographed as it was, with all the imperfections and difficulties a book of its age can present. Our aim is the preservation of these fine examples of creative human thinking in print.
