...simplest maneuver for a sailing spaceship, says Dr. Cotter, will be escape from the earth. The satellite will be placed in an orbit in the plane of the earth's orbit around the sun (see diagram). After spreading its sail, the satellite will be designed to have a slow turning motion, rotating once during every two trips around the earth. When it is moving away from the sun, its sail will be at right angles to the sun's light, and it will get the maximum push in a forward direction. By the time it gets...
Some time, some place in the dark backward and abysm of time, the first "living" thing was created, and evolution began. But even the simplest organism is made up of enormously complicated chemical compounds. How were these compounds produced in the slow aeons of the world's beginnings? Last week Dr. Melvin Calvin, professor of chemistry at the University of California, described some probable steps in the strange, speculative science of chemical evolution that led to the first glimmer of life...
...gadget-the simplest of them all in Western eyes-has already made its mark. "One of the first things I did, before we built a single apartment house," says Kano, "was to order thousands of Yale-type keys. The result has been staggering. Getting keys to their own front doors has done more to Westernize many Japanese than any other single factor." Kano's tenants agree. "Formerly," said one last week, "either my wife or myself or one of the children simply had to stay home when the rest were out: Japanese houses are quite open and there...
Proteins are enormously complicated molecules, and until Sanger's work on insulin, no one had ever been able to determine the structure of even the simplest of them. Chemists have known for many years that protein molecules are made of amino acids (nitrogen-containing organic acids) strung together in long chains or cables. By various kinds of rough treatment, the chemists could separate and count the amino acid building blocks. But this did not reveal their structural plan...
...success has finally arrived for 63-year-old Bucky Fuller. His geodesic domes are popping up like mushrooms all over the surface of the globe. Essence of the geodesic dome is to frame a sphere (the greatest possible space with the least possible surface) with combinations of tetrahedrons ("the simplest finite system you can have"), making a lightweight, easily assembled structure of wide span and low cost...
