Chemistry was practically at a stand-still until the time of Priestly, the discoverer of oxygen. Since then isolation of elements and a true understanding of the structure of matter have enabled scientists to make chemistry one of the most powerful benefactors of man. The molecular theory, the periodic laws, and the more recent physical contributions will probably be explained at length...
When a piece of iron or other substance is magnetized, the molecules yank one way. When the substance is demagnetized the molecules jerk helter-skelter. The magnetic yanking causes molecular friction and produces an appreciable amount of heat which Professor Wrilliam F. Giauque, University of California chemist, used last week to reach the lowest degree of cold yet attained...
...University of California owns. Liquid helium absorbed and withdrew the magnetically generated heat. At -459.1° Professor Giauque was stopped, regretting that he could not stride the stupendously difficult little step of .3° which would carry him to Absolute Zero where substances should retain no more heat, where molecular activity should completely cease. where all things should be coldly inert. But Absolute Zero must be unattainable on earth except in a perfect vacuum, for where there is substance there must be heat absorbed from radiations of the Sun or other stars...
...institutions of learning might probably consider an extension into the realm of maternity. When "Bacchanalian Arts 1a, 1b, 1d," grace dull course indexes, Universities may find a way to fill the cup of learning. "Fat rats, thin rats, scrawny rats" will throng after the elusive flute. "Heaviside Calculus" and "Molecular Forces" possess a soporific charm all their own, but who can foretell the rush of "black rats, white rats, and brown rats," to worship at the feet of a seer who could outline the indefinable incompatibility of champagne and muligataway...
...Molecular Forces in Liquids and Gases," Professor Black, Jefferson Labora...
