...relation of Chemistry to industry is one of the most important practical applications of chemical knowledge. The common industrial processes for manufacture of coal gas, soap, rubber, paint, heavy chemicals, etc., are made clear by explanation from the industrial rather than the laboratory point of view, and a series of twelve trips to representative factories of the neighborhood gives the student an opportunity to gain first-hand ideas about how industrial large-scale operations are carried...
Geologists have paid curiously little attention to the event at Durango. Local men hazard diverse opinions. One supposes that coal beds deep within Carbon Mountain have ignited, generating gas which is bursting the mountain apart and forming cavities into which the mountain collapses. For evidence the burning-coal theorists point to a gas-like hissing which often accompanies a rock slide, to the sulfurous smell, and to pieces of shale charred red and yellow. On the other hand. Dr. S. Boyd Calkins, science teacher in the Durango high school, points to the earthy effusions which last week oozed from Carbon...

He had gone to Glasgow with his friend, classmate and mentor, Edward Francis ("Eddie") Eagan (Fighting for Fun), to enter the championship bout. The reigning champion, a coal miner, gave His Lordship a terrible drubbing, broke one of his teeth half in two, left another hanging by a thread...
...resulted when alpha particles struck lithium atoms confirms the Einstein Formula, Dr. Bainbridge declared. The Einstein Formula which Dr. Albert Einstein reached through recondite logic, looks simple: Mc² equals E.* It simply demonstrates that mass and energy are interchangeable, that heat can bundle itself into a lump of coal as well as a lump of coal can dissipate into heat...
...River Rouge plant, populated by Rivera's chunky, concentrated figures. Others showed a pharmaceutical factory (Parke, Davis & Co.), airplane welders, poison gas workers, topped in huge scale by females representing the raw materials of Detroit's industries: a white woman for limestone, black for coal, yellow for sand, red for iron ore. Critics rated the frescoes first-class, noted an increasing hardness and sharpness in Rivera's detail. Nearly overlooked was a little panel high on one wall, showing a child being vaccinated in a serum laboratory. In the foreground were serum-giving animals, a horse...
