...able to span. In a recent issue of Nature, British scientific weekly, Dr. F. Rinne, University of Freiburg, Germany, suggested similarities between a crystal and a simple sperm cell which may be the means of drawing living and nonliving matter together. He pointed out that a chief characteristic of liquid crystals* is the so-called "straight-stretch" type of molecule which composes it. Protein molecules of sperm cells are also of the "straight stretch" type. In addition to this structural likeness, there is a likeness of optical behavior. Like crystals, sperm cells break in two the light which passes through...
...School, one day last week, moppets who were drowsily planning some means of truancy had their reveries abruptly interrupted and realized. The monotonous tamping of an oil-well driller 150 ft. away suddenly ceased and Swuss-shh! high over the top of the derrick rose a column of dirty liquid, filling the air with a fine spray of oil, sand, gas. Gauged at 65,000 bbl. per day, the gusher was pronounced by oilmen the greatest high gravity producer within their recollections. As delighted as its owners were the children who swarmed out to witness the spectacle, for the fire...
Aerocrete is made of Portland cement, sand and small quantities of lime, aluminum powder, soda. When poured out in thick liquid form, the presence of the aluminum powder in an alkaline solution causes a chemical reaction, liberates hydrogen, forms a cellular structure. Within a half-hour after pouring, aerocrete begins to puff up. At the end of an hour, expansion reaches its limit, the material hardens. By varying the amount of ingredients, expansion can be controlled, may vary from 50% to 150% of original volume...
