...stethoscope, noticed that his breathing was labored in the left lung. X rays showed that a large amount of fluid had collected in his chest. Doctors later learned that the fluid was blood that had congealed into a jelly-like glob and was pressing against the upper left chamber of Burcham's natural heart (the Jarvik-7 actually replaces only the lower, pumping chambers). This pressure, known as cardiac tamponade, prevented blood from entering the artificial heart and caused it to back up into the left lung (see illustration...
...modern times has a political question divided the House so violently. Some Republicans last week called their Democratic colleagues "thugs" and "slime" and spoke of using "guerrilla warfare" and "massive retaliation." There was even wild talk about Republican legislators staging mass sit-ins, locking the doors of the House chamber or chaining themselves to the rostrum in protest. The source of the bitterness: after months of recounts in the Eighth District of Indiana, a House panel ruled that Democratic Incumbent Francis McCloskey had beaten Republican Challenger Richard McIntyre by four votes out of 234,055 counted...
...single, heavier helium nucleus, a tiny bit of their individual masses is converted into a tremendous amount of energy. In weapons, that energy is uncontrolled and destructive. To channel it into a usable form, scientists must be able to control the fusion reac- tion and confine it to a chamber, which requires surmounting some formidable physical constraints. The hydrogen nuclei must be crushed together with enough force to overcome their mutually repellent positive electric charges. In H-bombs, that force is supplied by the detonation of a fission bomb, or A-bomb...
...tubes terminate inside an airless 16-ft.-wide aluminum chamber, each entering it from a different direction. Inside, the focusing lenses are arrayed around a pellet of deuterium and tritium, two heavier varieties of hydrogen atoms. Scientists hope that when the beams simultaneously hit the pellet, which is smaller than a grain of sand, the temperature of the pellet's outer surface will be raised to 100 million degrees, causing it to vaporize explosively. Just as a rocket is pushed forward by its tail exhaust, the vaporizing surface would exert a force inward, compressing the pellet to a density...
...excelled in. "You can't really have a major Handel festival without paying attention to his operas, and the difficulties for undergraduates in putting together an opera are nearly insurmountable," Wolff explained. "If you look at Bach's works, you have an ideal repertoire that can be tapped by chamber music, choral and orchestral groups...
