Analysis will undoubtedly resolve the process of organic creation into an ever-growing number of physico-chemical phenomena, and chemists and physicists will have to do, of course, with nothing but these. But it does not follow that chemistry and physics will ever give us the key to life. A very small element of a curve is very near being a straight line. And the smaller it is, the nearer.
Its authorship is as yet unknown, but it is believed to be the joint production of two of the most eminent physicists in Great Britain, and certainly the accurate knowledge and the ingenuity and subtlety of thought displayed in it are such as to lend great probability to this conjecture.
I allude to the mention which you make of some of the eminent physicists who have contributed by their discoveries and experiments to our knowledge of the phenomena of electro-magnetism.
Let us see how these two theories have been actually worded by the students of science themselves who have maintained them. 'The sudden blazing forth of this star, says Mr. On the other hand, the German physicists, Meyer and Klein, consider the sudden development of hydrogen, in quantities sufficient to explain such an outburst, exceedingly unlikely.
In whatever way you look at it, the principle of Carnot furnishes, in the immense majority of cases, a very sure guide in which physicists continue to have the most entire confidence. To apply the two fundamental principles of thermodynamics, various methods may be employed, equivalent in the main, but presenting as the cases vary a greater or less convenience.
The very existence of an ocean of ether enveloping the molecules of material bodies has been doubted or denied by many eminent physicists, though of course none have called in question the necessity for some interstellar medium for the transmission of thermal and luminous vibrations.
When physicists speak of these forces if the necessities of language and the brevity of the explanation constrain us to adopt the term forces, as though they were real substances they certainly do not believe, nor wish others to believe, that they are really such.
We take our time from the geologists and physicists; and it is monstrous that, having taken our time from the physical philosopher's clock, the physical philosopher should turn round upon us, and say we are too fast or too slow. What we desire to know is, is it a fact that evolution took place?
But it is permitted to hope that the physicists of the future will do still better than those of to-day; and perhaps we may catch a glimpse of the time when we shall begin to observe that the standard, which is constructed from a heavy metal, namely, iridium-platinum, itself obeys an apparently general law, and little by little loses some particles of its mass by emanation.
"This is not nearly as convenient as a pot that gets cold on the outside so it can get hot on the inside," observed Soames. "From a castaway's standpoint it's crude. But this is what can happen from two civilizations affecting each other without immediately resorting to murder. You might try it." The two physicists blinked. Then the short man said uneasily: "Can we do it?"
