Excerpt from Light These lectures were given at the American Museum of Natural History during the winter of 1908-9, when I had the honor of occupying a chair of Mathematical Physics at Columbia University in the City of New York It is not easy, in such a place, for a man of science to sit in cloistered calm, far from the distractions of the busy world of action, and to pursue research merely for self-illumination or for the edification of a caste of intellectuals. The throb of life is all around him, and it impresses him with the duty of responding to the demands of an active-minded people for reliable information on the most recent developments of science. He is expected to know, but not only to know, but also to communicate. And so, on being invited to give the Jesup Lectures, I attempted to describe the salient features of the modern theory of light within the narrow compass of ten lectures, and undertook in doing so to avoid technicalities as much as possible. I have had specially in view the man of intelligence who lays no claim to scientific knowledge, but who wishes to know what all the talk of science is about, and, in particular, why the physicists make such strange postulates as ether and electrons, and why they have so much confidence in the methods that they employ and the results that they obtain.
