This primer on physics, written in 1877 by the most eminent physicist of the 19th century, is intended as a brief introduction to Newtonian mechanics for students and educated lay readers. Though by modern standards this small work covers no new ground, it attests to the logical rigor and powers of elucidation of a scientific genius, whose insights into electromagnetism and the chemistry of gases were pivotal to the great discoveries in physics during the 20th century. Einstein described Maxwell's influence on the scientific understanding of the physical universe as the most profound and the most fruitful that physics has experienced since the time of Newton. Maxwell's ideas also laid the groundwork for Max Planck's subsequent development of the quantum hypothesis. In seven concise and lucidly written chapters, Maxwell covers all the basic concepts of physics: time, space, matter, mass, force, momentum, velocity, acceleration, laws of motion, work, energy, gravitation, and many other ideas. This edition also includes a chapter on equations of motion from Maxwell's classic Electricity and Magnetism, plus two appendices, one on the relativity of motion and the other on the Principle of Least Action. Complete with many useful illustrations to clarify the concepts discussed in the text, this accessible work is well suited for history of science courses or as a still-relevant introduction to basic physics for the average reader.
About the Author: Physicist JAMES CLERK MAXWELL (1831 - 1879), born in Edinburgh, Scotland, was the only child of lawyer John Clerk Maxwell and enjoyed a comfortable middle-class family. After an early education at home, Maxwell entered the University of Edin-burgh at age sixteen and then the University of Cambridge in 1850, where he won early recognition with his mathematical papers. One of these papers, On the Stability of Motion of Saturn's Rings (1859), was especially important and foreshadowed his later investigations of heat and the kinetic theory of gases.

Maxwell was professor at Marischal College, Aberdeen (1856- 1860), and King's College, London (1860-1865). He was elected to the Royal Society in 1861. He resigned his professorship at King's College in 1865 to devote himself to writing his famous work on elec-tromagnetism, A Treatise on Electricity and Magnetism (1873). In 1871 he was appointed first professor of experimental physics at Cam-bridge, where he supervised the design and construction of the Cavendish Laboratory. Maxwell is also known for his studies of color perception, color blindness, and geometrical optics. In addition to his papers in these fields, he wrote a classic elementary text in dynamics, Matter and Motion (1876). His other books were Theory of Heat (1870) and Elementary Treatise on Electricity (1881).
