...fast, non-smudge printing, various means have been devised to make ink dry almost instantly when it hits the paper-absorption, evaporation, oxidation, polymerization (molecular clustering). In the "flash-dry" process, the newly printed paper passes between jets of flame and the liquid part of the ink ignites with a flash, leaving a dry residue. The June Technology Review (M. I. T.) describes a new "frozen" ink for porous papers like newsprint. The ink is solid at room temperature. It is fed like lumps of coal into the press, which heats it to fluidity, at 200° F. On reaching...
Polymerization (the process of linking molecules together in long chains) is the key to successful artificial rubber. In natural rubber such molecular chains hold the substance together when it stretches. When chemists stopped trying to duplicate natural rubber's chemical composition, and set out to duplicate its structure and mechanical action, results followed...
...progress is made up the pyramid, sense impressions are connected by theorems and syntheses which cover more & more phenomena, so that the basic statements need be fewer (the cross section of the pyramid diminishes). Such progress was made, for example, when heat was found to be energy of molecular motion; and when light, X-rays, gamma rays, wireless waves, ultraviolet and infrared radiation were all disclosed as electromagnetic vibrations. At the pyramid's apex there should be a master synthesis embracing all physical phenomena...
...Scientific Congress in Washington, the sage of Princeton confessed himself baffled. "For the time being," he said, " we have to admit that we do not possess any general theoretical basis for physics which can be regarded as its logical foundation. The field theory, so far, has failed in the molecular sphere...
