...natural setting, social conditions and human psychology are its concerns. It acknowledges that the private car is and for scores of years will be the most used form of transportation. Its expression is the U.S. Interstate Highway system, and its symbol is the red, white and blue shield that seems to say, "Heave a sigh of relief and get moving...
...travel it now is to see the ideal when one is on some freshly built stretch with not a car in sight, and the obsolete when the sign says FREEWAY ENDS and the car is dumped onto a truck-jammed road bearing the telltale black-and-white shield that identifies the old federal-aid highway system. Interstate 40, for example, turns into Route 66, once famed in song and legend, and now a dreary bore lined with signs like SEE GILA MONSTERS 1 MILE...
Finally one of the co-detectors of man-made neutrinos, Dr. Frederick Reines of Cleveland's Case Institute of Technology, came up with a successful method. Near Johannesburg, he went to work in a 10,492-ft.-deep chamber, which he knew would shield out nearly all radiation from the surface except the deep-penetrating neutrinos. He lined the sides of the chamber with 36 containers of common mineral oil. Then he waited for an expected reaction of several stages: 1) the neutrinos hit atomic nuclei in the rock surrounding the chamber; 2) this interaction generated particles called...
...canister, about 41 ft. long and 10 ft. wide, that will be attached to a stripped-down Gemini. The two vehicles will be lofted together into space by a Titan IIIC rocket. Once they are in orbit, the spacemen will crawl through a hatch in the Gemini heat shield and enter the lab. For the return to earth, they will simply reverse the procedure, then detach from the 7½-ton canister and descend in the Gemini. Later on, other Gemini crews will take off from the earth, link up in space with the lab, and continue the work...
...made in Vietnam, and elsewhere, all possible mistakes to say the least. For this reason we know the justification for a foreign army fighting in Vietnam and we cannot believe those stories which always cradled the misery of the poor peoples. We were, as President Johnson said, the "vital shield of freedom," but we were the only ones to believe that and finally this shield was only covered with blood and mud. We were also, as he said, "the guardians at the gate" against the communist aggression; but what kind of aggression is it when the Vietnamese people...
