...tested at "Suzy," North American's test facility in the Santa Susana Mountains northwest of Los Angeles, it is trucked to Leuhman Ridge in the Mojave Desert. There, the test stand towers 275 ft. above the rocky ground. Tucked in its steel skeleton are tanks for lox (liquid oxygen) and kerosene, while stairs, cables, and many-colored pipes thread their way among the girders. The F-1 looks small in this immense structure, but it does not act small. After a careful countdown, a brilliant spout of flame bursts from its throat, and a sound beyond description rolls across...
...This mammoth electronic ear rotates, twists at odd angles, and can point toward any part of the sky. However it turns, two fair-size houses filled with electronics turn with it, and the thin, frail voice of Telstar is plucked from the sky. Fed into a maser cooled with liquid helium and sent through other intricate equipment, that voice is beefed up and transformed into TV programs or hundreds of voice signals...
Strauch has carried out these studies at the Cosmotron of the Brookhaven National Laboratory using a liquid bubble chamber The chamber was pioneered by the Cambridge Bubble chamber Group, high energy physicists from Harvard and several other New England institutions...
When the X rays show that the tip of the tube is in the thalamus, Dr. Cooper lets in enough liquid nitrogen to drop the tip temperature to zero or -10° C. This knocks out the nerves, but does not destroy them. He asks the patient to raise an arm, or leg, or both: if the patient has full control of his limbs, with no tremor remaining, the tip is in the right place...
Then Dr. Cooper admits more liquid nitrogen, to drop the tip temperature to -40° or -50°. In less than five minutes, this rapid freezing kills the offending, misfiring nerve cells. If the freezing extends a bit too far and the patient becomes unable to move his arm satisfactorily, Dr. Cooper has 30 seconds in which to correct the error and rewarm the thalamus. Most patients can be out of bed the same day and out of the hospital within a week...
