The Untouchable Page 374 In alternating layers of experiment and theory these three men built up the modern theory of electromagnetism, and demonstrated the identity of light with electromagnetic waves. Human Traits and their Social Significance But gravity emasculates electromagnetism, causing it to behave like the nuclear forces on the very smallest scales.

The Practical Values of Space Exploration Report of the Committee on Science and Astronautics, U.S. House of Representatives, Eighty-Sixth Congress, Second Session But if it were so, we might apparently hope, by experiments in electromagnetism, to obtain absolute motion, and to place in evidence the translation of the earth relatively to the ether. The New Physics and Its Evolution If others could make better instruments for the same purpose, they were at liberty to use electromagnetism. Samuel F. B. Morse, His Letters and Journals In Two Volumes, Volume II Passing on to the consideration of another phase of the phenomena of electromagnetism, the reader's attention is called to Fig. Edison, His Life and Inventions In a later development, his Unified Field Theory, the great physicist embodies in one mathematical formula the laws of gravitation and of electromagnetism. Autobiography of a Yogi To do this must therefore be our first task, if we want to attain to a realistic picture of electromagnetism.
