Prof. S. P. Thomson in "Electricity and Magnetism," says: "Gilbert made the discovery that the compass points north and south because the earth is also a great magnet. Faraday said: 'All matter is in a magnetic condition.' Sir Oliver Lodge says: 'The idea that magnetism is a whirl of electricity is as old as Ampere. Perceiving that a magnet could be initiated by an electric whirl, he made the hypothesis that an electric whirl existed in every magnet.'" Maxwell announced the proposition that electro-magnetic phenomena and light phenomena have their origin in the same medium and are identical in nature. Hertz, by actually producing, detecting and controlling electric waves, caused the discovery of wireless electricity. And it is by the wonderful wireless telegraphy of light that man is put in communication with every considerable body in the universe, including even the invisible. By it the goings on in Sirius and Algol, Orion and the Pleiades are reported across enormous stretches of millions of millions of miles of space. And by the vibratory motion of the invisibly small, all things are revealed; the infinitely little has enabled us to conquer the inconceivably big. I hold seeing and hearing are the simplest examples of wireless telegraphy. Elihu Thomson, the great electrician, says: "Hertz proved that all luminous phenomena are in essence electrical. Wireless electricity is the outcome of Hertz's experiments on electric waves, and electrical conditions and actions are more fundamental than hitherto regarded." William Ramsey, the distinguished chemist, says: "It is a primary assumption that atoms of elements or in certain cases groups of atoms are themselves electrified, and atoms possess positive and negative poles, and combinations ensue between such oppositely electrified bodies." Mr. Francis Grierson, a prominent scientist of London, in a recent London periodical, says: "So far as we know electricity is the soul of visible form. What we call brain waves have an analogy to electric waves. The discoveries and inventions of the last ten years have made child's play of every previously known system of philosophy. The simple but amazing facts disclosed during the past five years, render the dreams, speculations and guesswork of the past absurd. The little we know in a practical way is more than all the philosophers of the past knew from Aristotle to Leibnitz." Prof. Langley, in his address at the 1902 session of the American Association of Science, stated that, "up to 1872 it was almost universally believed that there were three different kinds of energy--actinic, luminous and thermal--represented in the spectrum;" but he affirmed: "There is only one radiant energy which appears to us as actinic, luminous or thermal, according to the way we observe it.
