Show Molecules In 31 at t-ir It seems a difficult TmOri taking i cept the theory that granite, glass and precious Btones, not excepting diamonds, are composed of independent particles that are continually in exceedingly rapid rap-id motion. These active molecules are Baid to rotate and swing around a central cen-tral point with such force and rapidity that they constitute, to all intents and purposes, a solid mass. Upon being divided di-vided they whirl around a new center as rapidly as before, the molecules passing a given point Borne millions of times in a second of time. This theory would at first glance seem incompatible with the well understood belief in the hardness and impenetrability of the diamond, but this is easily explained. The almost incalculable rate of speed drives the atoms at-oms against the drill or cutting edge that seeks to penetrate it and dulls it without permitting it to make the slightest slight-est impression. On this theory it appears ap-pears that glass cutting is merely the bringing together of two bodies consisting consist-ing of molecules moving at different velocities. ve-locities. As a matter of course, the most powerful atoms break up the softer ones, and so this operation is merely a war of particles, in which the superior force is triumphant. New York Ledger. |
