Thinking both had missed, and muttering to himself in a cold rage, Gilmore followed the MIG through another wrenching, rolling loop of a brain-draining six gravities, then cut loose a third Sidewinder. The enemy's tail section came apart in a tumble of torn metal, and the plane pitched earthward. In fact, Gilmore's first Sidewinder had also scored, and the Red pilot had ejected. In getting the first MIG-21, Gilmore had killed it twice...
...next year. As a spectacle, the oxygen furnaces of such firms as Bethlehem, National, Republic and Kaiser out-inferno Dante. When a pipelike lance stabs the molten iron with a Mach 2 jet of high-pressure oxygen, the cauldrons burst into a maelstrom of 3,000° metal, boiling noxious smoke and spewing fireworks. The process not only enables steelmen to cook a batch of steel in 40 minutes instead of six to ten hours in an open-hearth furnace but produces metal with fewer strength-sapping impurities as well...
...CONTINUOUS CASTING. The idea is so obvious that Bessemer filed a patent on it 101 years ago, but complex production bugs stymied its use until recently. The ordinary method of casting is to pour the metal into ingot molds to harden, strip away the mold, reheat the ingot and roll it into semifinished shapes. Continuous casting eliminates these cumbersome steps. A ladle atop a tower pours white-hot steel into a 2-to-4-ft-deep oscillatfhg copper-lined mold. As the mold bottom is withdrawn, an unbroken billet of barely crusted steel creeps down through cooling water sprays...
...most rewarding work came in October and November when we had a chance to pour concrete. We shoveled sand and gravel and concrete into metal bowls which students carried on their heads and threw into the cement mixer. Others picked up wheelbarrows full of cement, raced down narrow boardways and dumped them into the stone bed of the foundation. It was hard work and the sun was getting hotter, but when the day was over we could see the floor of the building that we had made...
That, at least, is what Leary's cells told him. "I look around us," he continued, "and I see metal-all living things and all my cells hate metal-and I see the pollution of the air and the poisoning of the rivers and the concrete over the earth, and I have to say 'Baby, it's time to mutate...
