Heinrich Hertz discovered that in addition to the light, heat, and colour waves carried by ether, this substance also served to carry electric waves or vibrations, so that electric impulses could be sent from one place to another without the aid of wires.
A salesman, eh?" The speaker made a gesture as though pushing something from him with contempt. "Fudge! Travels, does he? Rot! He can't fool me. And then," with energy, "what did he used to do so much in Spatola's garret, eh? What did they talk about so much on the quiet? I ain't saying nothing about nobody, mind you. I'm a gentleman. My name's Hertz. I don't want to get nobody into trouble.
Hertz acutely remarks that the incident, as related by Borron, is not of such importance as to justify the stress laid upon the name, Rich Fisher, by later writers. We may also note in this connection that the Grail romances never employ the form 'Wise Fisher, which, if the origin of the name were that proposed above, we might reasonably expect to find.
The only differences which subsist are necessarily those due to the considerable discrepancy which exists between the durations of the periods of these two categories of waves. The length of wave corresponding to the first spark-gap of Hertz was about 6 metres, and the longest waves perceptible by the retina are 7/10 of a micron.
Thiele expressed himself warmly and enthusiastically about the power which he had seen in me, combating against the oppression and the misery of life. I received a stipend for travelling; Hertz a larger and I a smaller one: and that also was quite in the order of things. "Now be happy," said my friends, "make yourself aware of your unbounded good fortune!
Jo Hertz, in one of those pinch-waist belted suits and a trench coat and a little green hat, walking up Michigan Avenue of a bright winter's afternoon, trying to take the curb with a jaunty youthfulness against which every one of his fat-encased muscles rebelled, was a sight for mirth or pity, depending on one's vision. The gay-dog business was a late phase in the life of Jo Hertz.
At about the same time Helmholtz formulated a somewhat similar electro-magnetic theory of light; but even the weight of this combined authority could not give the doctrine vogue until very recently, when the experiments of Heinrich Hertz, the pupil of Helmholtz, have shown that a condition of electrical strain may be developed into a wave system by recurrent interruptions of the electric state in the generator, and that such waves travel through the ether with the rapidity of light.
The First Suggestion Morse Sends Messages Through the Water Trowbridge Telegraphs Through the Earth Experiments of Preece and Heaviside in England Edison Telegraphs from Moving Trains Researches of Hertz Disclose the Hertzian Waves.
Stimulated by Maxwell's mathematical conclusions, Hertz and Marconi were soon afterwards able to demonstrate those phenomena which have led on the one hand to the electro-magnetic theory of light, and on the other to the practical achievements of wireless communication.
I'm going." And she went. Jo stayed on in the apartment until the lease was up. Then he sold what furniture he could, stored or gave away the rest, and took a room on Michigan Avenue in one of the old stone mansions whose decayed splendor was being put to such purpose. Jo Hertz was his own master. Free to marry. Free to come and go. And he found he didn't even think of marrying.
