...doughnut of magnet steel, 656 ft. in outside diameter. Last week British Physicist John B. Adams, chief of CERN's Proton Synchrotron Division, ordered slight corrections in the magnetic field, watched as the protons sped faster and faster around their circular track inside the doughnut, triumphantly saw the oscillograph's curve reach 29 Bev, putting CERN's machine far ahead of the ten-Bev Russian accelerator at Dubna...
...test his hunch, Lissmann touched the water with two electrodes connected with an oscillograph. When the two-way fish swam near, a series of regular electrial pulses showed on the oscillograph een. Then Lissmann dipped ends of a copper wire into .the aquarium. The little fish fled in terror, its radar apparently mistaking the wire for a bigger and hostile fash. It also fled from a wire carrying artificial electric pulses. But when Professor Lissmann fed its own pulses back into the water, the fish attacked the electrodes presumably taking them for a rival of its own species...
Repeating Dr. Donald Griffin's experiment [for his sonar navigation experiments, he used bats which had been made to hibernate in a humidified refrigerator-TIME, May 1], I removed a bat from my belfry, chucked him in my refrigerator, rigged my oscillograph, and turned him loose...
Bats can and do make audible cries, but the sounds they use to navigate by are ultrasonic-much too high-pitched (up to 120,000 cycles per second) for human ears to hear. So Dr. Griffin rigged a special microphone and hitched it to a cathoderay oscillograph. Each inaudible peep from a defrosted bat made a measurable pattern of light on the oscillograph screen...
