...Safeguard system has four key elements. PAR (perimeter acquisition radar) detects an enemy ICBM at long range some time after it has been launched, calculates its path, and then passes the missile track along to the less powerful but much more complex MSR (missile site radar). MSR then directs two types of ABMs against the incoming warheads. The long-range Spartan is designed to make an intercept above the atmosphere, at altitudes between 200 and 400 mi. The smaller Sprint would seek out and destroy warheads that penetrated the Spartan screen by intercepting them within 40 miles of the target...

The ringmaster dominates the scene simply through his bulk and closer position to the camera, but Lola remains independent...
...Brown University into some of the liveliest academic reforms in the U.S. He did it by sheer intelligence, without manhandling a single dean. Last month Magaziner delivered the senior class valedictory, collected his magna cum laude degree in an interdisciplinary program called Human Studies, twirled his Phi Beta Kappa key and looked ahead to two years at Oxford as a Rhodes scholar. Brown itself looked ahead to sweeping curriculum changes that might never have occurred without Magaziner...
