Not many are specializing in that field. Edison is bringing forth some of the wonders of electricity; Burbank is doing marvelous things in the plant world; we have warriors and statesmen and philosophers and philanthropists and great financiers a-plenty; we have scientists too, and some of them are helping. Have you ever heard of Sir Oliver Lodge and Lord Kelvin?" No; she never had.
Meeting them one evening at a court festivity, I was told by Hoffmann of an experience of his in Scotland. He had arrived in Glasgow late on Saturday night, and on Sunday morning went to call on Professor Sir William Thomson, now Lord Kelvin. The door-bell was answered by a woman servant, of whom Hoffmann asked if Sir William was at home.
Lord Kelvin has called attention to the fact that when two pieces of paper, one white and the other black, are placed in exactly similar glass vessels of water and exposed to light, the temperature of the vessel containing the black paper is raised slightly higher than the other.
Clearly, if there were no friction, the ring's inertia must make it a permanent structure. Only the frictionless medium was lacking to fulfil all the conditions of Helmholtz's indestructible vortices. And at once Lord Kelvin bethought him of the frictionless medium which physicists had now begun to accept the all-pervading ether.
In thought the Schools, like the Church, raised ignorance to a faith and degraded dogma to heresy. Evolution survived like the trilobites without evolving, and yet the evolutionists held the whole field, and had even plucked up courage to rebel against the Cossack ukase of Lord Kelvin forbidding them to ask more than twenty million years for their experiments.
It reminded me forcibly of what Lord Kelvin, then plain William Thompson, and Professor Blackburn had done when spending a Summer vacation at the seaside, while they were undergraduates of Cambridge University.
He showed me by calculations on paper, which Lord Kelvin, no doubt, or Professor Lodge, or Professor Karl Pearson, or any of those great scientific people might have understood, but which simply reduced me to a hopeless muddle, that not only was such a substance possible, but that it must satisfy certain conditions. It was an amazing piece of reasoning.
No one, so far as we know, had any strong desire to do so. No one conceived that the telephone would ever be any more than a whimsical oddity of science. It was so new, so unexpected, that from Lord Kelvin down to the messenger boys in the telegraph offices, it was an incomprehensible surprise.
Have you seen beautiful Kelvingrove, through which flows the classic Kelvin? In many world-famous cities have I been and yet seen nothing more beautiful than the view on one side of Partick Bridge."
The relative advantages of reclaiming a given area of soil for purposes of cultivation, and of converting the same land into a tidal basin in order to generate power through the inward and outward flow of the sea-water, were contrasted by Lord Kelvin in the statement of a problem as follows: Which is the more valuable an agricultural area of forty acres or an available source of energy equal to one hundred horse-power?
