Before dawn one morning last week, a plastic-bomb* explosion wrecked Mayor Blanc's ancient Citroën, parked in front of the Beau-Rivage. Blanc leaped out of bed and ran for a phone in a ground floor office-just as the bombers had expected. Fifteen seconds after the first bomb, a second and larger one exploded on the window sill of the office, blowing off Blanc's shoulder and part of his face. "They got me," he gasped and 15 minutes later he died. Who were "they"? Presumably right-wingers who want no parleying with...
...example is the senior-year aerodynamics course taught by Associate Professor Erik Mollö-Christensen. First, Mollö-Christensen holds a lottery, and the number each student draws corresponds to something in the lab-a piece of wire, a piece of plastic tubing or of plywood. Working in pairs, the students are required to determine the modulus of elasticity of the material they drew. Two students, working with a piece of brass, determined its elasticity by measuring the speed at which sound passed along it. Explains Mollö-Christensen: "They can do it any way they want to-so long...
Assistant Professor Richard Thornton has still another method of teaching do-it-yourself science in his electrical engineering classes. He created a kit for his students consisting of a plastic pegboard and a plastic box full of tiny parts-200 resistors, 50 capacitors, 6 transistors, etc. About the size of a thin textbook, the kit costs $25-and with it several students, working together in their dormitory, can fashion such things as a digital computer or an elementary TV system...
...worked in an iron mine 1.600 ft. below the earth's surface. For quick energy, the methodical Hiebeler got an Austrian jam factory to devise a special marmalade packed with calories and vitamins. He designed boots armored with three layers of outer leather; he bought special plastic helmets and tough, extra-thin ropes. Keeping their plans a tight secret, the men practiced all winter on rocky, ice-coated walls. A fortnight ago the four slipped out of their hotel before dawn and tackled der Eiger...
Enclosed though he was in 9-ft. by 5-ft. tank, Biologist Joe D. McClure was not alone: connected with him by pipes were several billion or trillion single-celled algae (Chlorella). Looking like grass-green soup, the algae were housed in tall columns faced with transparent plastic and brilliantly lit by a bank of fluorescent lamps. Parades of bubbles climbed up the columns-and it was those bubbles, enriched with oxygen by the algae, that McClure last week breathed for 26 hours before emerging hale and hearty...
