University Daily Kansan Friday, April 20, 1962 Page 10 KU Speed Trap Will Be Used Again This Year A speeder races down Jawhawk Boulevard at 45 miles per hour and passes over a cable. A second later, the speeder passes over a second cable. The speeder has just been caught in the KU police speed trap. LT. EDWIN W. FENSTEMAKER of the KU police explained how the speed trap worked. This speed tran will be used this spring on several campus streets for the fifth straight year. "The device operates on an electric timing principle." Lt. Fenstemaker said. "When the speeder crosses the first cable, it starts a clock. When he crosses the second cable, the speeder stops the clock." "The device gives the speed of the car in seconds and also in miles per hour," he said. He said the cables are usually placed about one half block apart. He said the electric speed trap has an advantage over the radar speed check device. "THE RADAR SYSTEM reflects the speed back for only a moment," he said. "The electric system can stop the clock and hold the speeder's time." Lt. Fenstemaker said that the speeder could see that he was breaking the speed limit by reading the clock. Joe Skillman, KU police chief, said that speed violators will be given tickets ordering them to appear at Lawrence Police Court. Sunyside Avenue in front of Summerfield Hall. Naismith Road in front of Allen Field House and Murphy Hall. CHIEF SKILLMAN LISTED the places the speed check may be set up this spring. They are: Fifteenth Street in front of the Nuclear Reactor Center. West Campus Road in front of Joseph R. Pearson and Carruth-C'Leary residence halls. Jayhawk Boulevard in front of the Kangas Union and Strong Hall. Memorial Drive Sunnyside Drive. Chief Skillman said that the speed check is effective not in terms of arrests but in keeping people aware that there is a speed check. Physicists Say Time Affects Gravity's Pull WASHINGTON — (UPI) A physicist said recently that space science may determine in the next five years whether gravitation is growing weaker with the passage of time The physicist, Dr. Robert H. Dicke of Princeton University, believes that as the universe expands, "the strength of the gravitational interaction may decrease steadily." DICKE DISCUSSED gravitation and space science in a lecture broadcast overseas on the Voice of America. Most scientists believe as Einstein did that gravitational strength is fixed. But a few, including Dicke, believe gravitation may have been "substantially stronger when our galaxy was young." If gravitational interaction has been growing steadily weaker, the fact has had great influence. Dicke said, on the history of the solar system, the stars, and the galaxies. DICKE ALSO SAID astronomical studies of the earth and moon also may show whether gravity is weakening. The moon's orbital speed has been going down. There are many possible explanations. But, he said, it has been determined "that the moon has been slowing down in its revolution about the earth by an amount consistent with the assumption of a steadily decreasing gravitational interaction."
