After the transistor came of age, there was still room for the venerable vacuum tube in the burgeoning world of electronics. But even though that world is getting bigger, its parts are getting smaller. Transistors, diodes, tunnel diodes and their proliferating cousins are getting more versatile as they shrink. And the vacuum tube is slowly dying out like the ancient dinosaur. At the annual exhibition held by the Institute of Electrical and Electronics Engineers in Manhattan's Coliseum last week, there was scarcely a tube anywhere to be seen...
After six years of labor by 500 men, and at a cost of 17 lives and $35 million, a two-lane tunnel has been driven 3.6 miles through the rock. On the Swiss side, a 3.4-mile covered access road is lifted to the tunnel mouth by graceful concrete pylons. On the Italian side, another such road, pyloned and covered (for protection against snow and landslides) moves 6.4 miles in graceful hairpin turns down to St. Rhémy. Motorists have the impression of driving along an enormous veranda with breath-taking views of the Aosta valley...
...tunnel entrance, Swiss and Italian formalities are handled in a single customs office, and drivers pay the fares, ranging from 90? for a motorbike to $18 for a bus. The neon-lit tunnel, 14 ft. 9 in. high, rides over a pipeline that brings oil from Genoa to a Swiss refinery at Collombey. The new St. Bernard, which will be formally inaugurated by the presidents of Italy and Switzerland in June, is the world's longest auto tunnel. But not for long. The Mt. Blanc tunnel of over seven miles from France to Italy will surpass it when...
...Secret Tunnel. Dr. Pritchard thinks that Zarethan was a city of Canaanites who were ruled by the Hebrews in Jerusalem, but he is also convinced that its site was inhabited long before the Hebrew invasion. For one thing, it had plenty of water, a rarity in the Jordan Valley. After spotting springs that still flow from the foot of the mound, Dr. Pritchard knew by experience what to look for next. Leading down the side of the mound he uncovered 86 stone steps of a staircase with walls on either side and another in the center. Before erosion destroyed...
...Beethoven's Second Symphony, the audience was suddenly jolted by the whapping of wood blocks and the toneless horn-blowing of Yannis Xenakis' Pithoprakta. The Greek composer's work was so radical that this first U.S. performance sounded something like skeletons dancing in a wind tunnel. The audience found Bernstein's comments condescending. "A lot of mathematical formulas which I cannot follow," he said of the composition...
