Adaptive-optics systems may sound complicated, but they pale beside another technological trick that will ultimately boost telescopes' power even more. Called interferometry, it achieves the precise focus of a truly huge telescope without actually having the thing built. Instead, light is combined from widely separated telescopes--the two Kecks, say, whose observatory building was designed with a basement-level chamber for that purpose, or two or more of the four VLT telescopes in Chile. The system is dauntingly tricky and complex, but its astonishing precision will let astronomers tease out the details of galactic structures and distant solar systems...
...even this remarkable technology could become obsolete--along with the giant telescopes on Mauna Kea, Chile and everywhere else--if the grandiose plans of the world's astronomers come to pass over the next couple of decades. Telescope designers are already thinking about the next generation of ground-based supergiant telescopes, devices that will range in size from 30 m (100 ft.) across to a staggering 100 m, or 330 ft.--a telescope mirror wider than the length of a football field. These will probably be scaled-up versions of the Kecks, using hundreds of individual mirrors aligned to make...
...left unattended and drowned. And children are not protected in Dallas either. There two-year-old Joel Hernandez allegedly was beaten so severely that he had to be placed in a body cast. Yet social workers let him stay with his parents, then never set eyes on him--even after 15 visits to the family home brought no one to the door. All the social workers did was send a certified letter. Joel's body was later found in a shallow grave. His stepfather and uncle are charged with his murder...
...that point, caseworkers did not even know which services might be available for children. They had no way of comparing notes or logging resources. They had no flexibility in meeting individual needs. They had no guidelines for contact between children in foster care and their birth parents. In most cases, the rules simply forbade...
...David, a judge sent him to the Eufala Adolescent Center, 150 miles away, where kids who escaped were hunted by dogs. David was kept secluded in Building 112, locked in a 9-ft. by 6-ft. cell with metal crates as a wall and a door painted black. Even though he talked of suicide, banged his head against the walls and screamed profanities, staff members treated him as a behavior problem. In March 1992 a center worker found David trying to hang himself and placed him under observation. Two days later, he tried again, using a shoestring. He suffered severe...
