...University could have avoided any impact on the city's housing market, Preusser said, by expanding the loan program to cover a ten community radius...
...struck. In its aftermath last week, even seasoned rescue workers were appalled by what they found as they dug through the ruins of Tabas. Of the town's 17,000 people, as many as 15,000 had perished in 90 horrifying seconds. Of 100 smaller villages scattered in a radius of about 60 miles, at least 40 had been leveled and an additional 10,000 lives lost. It was the world's worst earthquake of 1978. The toll of death and destruction was Iran's most calamitous since 1968, when an earthquake centered at Kakhk, 110 miles northeast of Tabas...
Aero-acoustics Expert William Meecham of the U.C.L.A. School of Engineering and Applied Science reports that people who reside within a 3-mile radius of Los Angeles International Airport have a 19% higher death rate than people who live six miles away. Most of the difference was in stress-related disease. Meecham's target group of about 80,000 people in the Inglewood and Lennox sections near the airport was compared with a control group similar in number, age, income and racial balance. The target group had 40% more fatal strokes and 140% more deaths from cirrhosis...
...Karl Schwarzschild considered one of general relativity's consequences. If a star were to become sufficiently compact and dense, Schwarzschild found, its gravity would so warp space and time around it that the star would literally enclose itself. For a celestial body of the sun's mass, the critical radius turned out to be about 3 km (2 miles). If the star shrunk beyond that, it would vanish. This so-called Schwarzschild radius, or event horizon, is in effect the black hole's boundary. Any matter crossing it simply disappears...
...Tomcat supersonic fighters into the air. With their Phoenix missile system, the F-14s can shoot down both the Soviet jets and the missiles they fire. Into the air too goes a U.S. propeller-driven Hawkeye warning and control plane whose sophisticated radar sees everything within a 250-mile radius. The plane's computers can monitor up to 300 targets simultaneously and report their location, speed and course to a computer aboard...
