...could easily build the Cobra to almost any response curve desired. Some of our first experiments had cartridges peaked at nearly 10,000 cycles. They did not give the fidelity of reproduction, did not make each instrument speak with its own natural voice, as did the curve finally adopted. This curve, measured on response to pure frequencies, peaks at a point slightly below 5,000 cycles, falls away, and then continues out flat to well beyond 10,000 cycles...
Into the Unknown. Fermi ran the test. At 9:54 a.m. he gave an order. A whining motor withdrew the automatic control rod. The Geiger counters on the instrument panel clicked a little faster; a pen drew a slightly higher curve on a strip of paper...
Newest of the college Observatory's outposts is the Solar Station at Climax, Colorado, operated, since 1940, under the joint auspices of the Observatory and the University of Colorado. Equipped with the first Lyot coronagraph in the Western Hemisphere, an instrument which enables astronomers to observe the corona of the sun without waiting for an eclipse, the Climax station is situated at an elevation of 11,520 feet above sea level, a higher altitude than that at which fliers are advised to use oxygen...
