"One reason for the success of Maxwell's teaching texts, and those of Thomson and Tait, is that they were... expounding in clear and persuasive language the new understanding in basic physics that their authors had been responsible for developing... In a way, Maxwell's contributions to the great ninth edition of the Encyclopaedia Britannica were a natural development of his zeal for teaching. They covered Atom, Attraction, Capillary action, Constitution of bodies, Diagrams, Diffusion, Ether, Faraday, Harmonic analysis, and Physical sciences. ...Maxwell deserves to be remembered as one of the nineteenth century's notable pedagogues. ...His expertise was built upon understanding, enthusiasm, hard work, and experience."
