...fourth raid on the compound since it was removed from the proscribed list two weeks ago. One reason U.S. planners are anxious to destroy the helicopters is that they could be used to transport mobile SAM antiaircraft missiles into positions near the DMZ. Once in place, the SAMS could zero in on the big and unmaneuverable B-52s, whose huge bomb loads have so effectively broken up North Vietnamese troop concentrations around Con Thien...
More than records are at stake in making the closest possible approach to absolute zero. As the motion of atomic particles decreases with increasing cold, scientists can study the particles more closely and learn more about the forces that bind them together...
More than Records. The cryogenic temperature range begins at a chilly- 150° F. and plummets to -459.7° F., or absolute zero, the point at which all thermal motion of the atom ceases. To attain these temperatures, scientists use expansion engines that compress gases, cool them and allow them to expand again, then repeat the cycle until they liquefy and eventually solidify. As the gases approach absolute zero, a sophisticated magnetization process extracts their remaining reservoir of heat. Because there will always be slight thermal motion of the atomic particles, scientists will never actually achieve absolute zero. But last...
Extreme cold also produces the phenomenon of superconductivity, which scientists are putting to work in scores of applications. As temperatures approach absolute zero, the electrical resistance of many elements and compounds suddenly disappears. These substances become highly efficient conductors, and small voltages produce large currents that continue to flow indefinitely even after the power source has been withdrawn. Scientists can now envision a superconductive power-transmission line cooled by liquid helium that could carry 100 billion watts of direct current for hundreds of miles with no appreciable losses...
Andy Tobias '68, President of HSA, handily disposed of the council's questions on the service until Richard Berner '68, spokesman for the HUC Sheet committee, admitted, "We see that your back is against the wall and you are driven to zero profit...
