This is the north pole of the physicist's world, the absolute zero of temperature the point at which the heat-vibrations of matter are supposed to be absolutely stilled. Theoretically this point lies 2720 below the Centigrade zero. With the liquefaction of hydrogen, a temperature of about -253 deg or -254 deg Centigrade has been reached. So the gap seems not so very great.
Assuming that the psychic condition is satisfactory for the production of a definite tone i.e., that it is heard mentally, what follows before it is actually produced, before it becomes a tone from the physicist's point of view? This will be clearer if we first consider the mechanism concerned and its functions in a general way.
The physicist's imagination is necessarily more concrete; since he is incessantly obliged to refer to the data of sense or to that totality of visual, tactile, motor, acoustic, thermic, etc., representations that we term the "properties of matter." Our eye, says Tyndall, cannot see sound waves contract and dilate, but we construct them in thought i.e., by means of visual images.
He had the physicist's heinous fault of professing to know nothing between flashes of intense perception. Like so many other great observers, Langley was not a mathematician, and like most physicists, he believed in physics.
"This is Soames," he said very distinctly. "I've got a tip for you. Pretend that you want to make something like the gadget that stops winds and warms places. You know the thing." The tall physicist's voice babbled. "I know!" said Soames bitterly, "I'm supposed to be dead or a traitor or something. But listen to me! You're a castaway and savages snipe at you.
Let us take an example which is salient enough; for, however arbitrary the conventional division of time may appear to a physicist's eyes, it is natural, when instituting a comparison between two epochs, to choose those which extend over a space of half a score of years, and are separated from each other by the gap of a century.
With the improvement of communications, the physicist's point of view thus introduced that of the economy of the energies of the community is only beginning; the economy of fuel, the limitation of smoke and fogs being symptoms of this and pointing to a more economic organisation of industrial activities generally.
Up to the present the painter has been able merely to wonder at the physicist's theory of colors, without gaining any advantage from it. The natural feeling of the artist, however, constant training, and a practical necessity led him into a way of his own.
Adjacent to the physicist's corner of the hut Atkinson is quietly pursuing the subject of parasites. Already he is in a new world. The laying out of the fish trap was his action and the catches are his field of labour. Constantly he comes to ask if I would like to see some new form and I am taken to see some protozoa or ascidian isolated on the slide plate of his microscope.
'I wish you would not sing that song! exclaimed Greif, a little impatiently. 'There will be time enough to exercise your voice upon it when we begin to throw away the torches. 'It is the only song I ever heard that has any truth in it, answered Rex. 'You ought to write one about the vortex, and call it the physicist's Lament, laughed the other. 'The idea is not new.
