- W4245702425 abstract "“OH! yes; I understand it all now. Electricity is the ether;” or, “Yes; it's just like everything else: electricity is a vibration.” These are the remarks one hears made by those who think that a few scattered words picked up at a popular lecture make things quite clear. It is no doubt unfortunate that repeating a form of words is a different matter from understanding them, and still more different from understanding the subject they are intended to explain. In this case there is the added misfortune that the form of words is not accurately repeated, and in its inaccurate form does not mean what is true. It is often hardly worth while remarking this to those who make these statements, because the words convey to them little or no signification, and are to them as true as any other unmeaning sentence. The connection between electricity and the ether is certainly not, as far as is known, well described by saying that “electricity is the ether,” and we cannot say with any certainty that electricity is or is not a vibration. Hertz's experiments have given an experimental proof of Maxwell's theory that electrical phenomena are due to the ether, and Hertz's experiments deal with vibrations. One cannot, however, say, because the pressure of 15 pounds per square inch exerted by the atmosphere is due to the air, that therefore “pressure is the air”: nor even, because a person who studied the properties of the air had studied them by means of sounds propagated through it, can one assert that “pressure is a vibration.” It is to be hoped no one will now assert that “electricity is pressure.” The example is given to illustrate the absurdity of the statements made as deductions from recent experiments, and not to teach any new theory. And yet one comes across people who, after listening to an interesting lecture Lord Rayleigh might give, illustrated by Mr. Boys's sound-pressure-meter, would make the above statements, and really think they understood them. That blessed word “Mesopotamia” comforted the soul of an old lady with some reason, for religion is to some extent a question of feeling; but in science it is high treason to truth to be comforted by unmeaning sounds—they should produce despair." @default.
