The thing was nearly half a mile high, a mighty rounded roof that covered an area almost three-quarters of a mile in diameter. Titanic that was the only word that described it. About it there was the peculiar shimmer of a molecular ray screen. Morey darted to the power room and set his apparatus into operation. He created a ball of matter outside the ship and hurled it instantly at the fort.
We may suppose that the inconceivably minute particles which by their rapid thrilling agitate the ethereal medium so as to produce light, are free to give out their peculiar tone of vibration only when floating apart from each other in gaseous form; but when crowded together into a condensed mass, the clear ring of the distinctive note is drowned, so to speak, in a universal molecular clang.
Under these circumstances, the radium still gives out heat, boiling away the liquid air until the latter has entirely disappeared. Instead of the radiation diminishing with time, it rather seems to increase. Called on to explain all this, science can only say that a molecular change must be going on in the radium, to correspond to the heat it gives out.
The great field of chemistry enters into the discussion as perhaps having the solution of the question within its possibilities. The practical electrician acts upon facts which he knows are true without knowing their cause; empirically; and so far adheres to the molecular hypothesis.
In general, absorption means the penetration of a liquid into the pores of a solid, and takes place according to the simple laws of molecular movements. Another difference is that certain foods undergo chemical change while being absorbed.
Molecular attraction and repulsion seem to say, "It is not in us; we are as active in the clod as in the flower." The four principal elements oxygen, nitrogen, hydrogen, and carbon say, "It is not in us, because we are from all eternity, and life is not; we form only its physical basis." Warmth and moisture say, "It is not in us; we are only its faithful nurses and handmaidens."
These physicists make even the slightest change in developmental phases whether statical, as in the case of crystals, or dynamical, as in the case of living organisms to depend on physical conditions, those aiding and abetting what they call the "molecular play of physical forces."
The whole process consists of a transference of molecular motion from the muscle to the weight, and gravitating force is the mere go-between, by means of which the transference is effected. These considerations will help to clear our way to the conception of the transformations which occur when a wire is moved across the lines of force in a magnetic field.
I have already more than once dwelt on the vividness with which he realised molecular conditions; we have a fine example of this strength and brightness of imagination in the present 'speculation. He grapples with the notion that matter is made up of particles, not in absolute contact, but surrounded by interatomic space.
Sedimentary strata have been carried down, by movements of the earth's crust, far below the surface, covered by other deposits, and subjected to great heat, which, aided by the water contained in the rocks and various chemical reactions, has effected a re-arrangement of the mineral contents of the strata, so that by molecular movements, the metamorphic crystalline rocks, including interstratified granites and greenstones, have been formed.
