...missilemen contemplate Ben Schriever, a tomorrow's man who often runs his command post in a grey flannel suit or tweed sports coat and slacks, who decorates his command post with an impressionistic oil painting of the U.S.'s first liquid-fuel rocket superimposed upon a plumed Chinese war rocket supposedly used by the Kin Tartars at the seige of Kaifeng (12321,* they recognize him as tomorrow's man. "Discerning, thinking leader . . . outstanding and extremely tenacious manager ... he has a big project concept" they say, adding that they "have great regard for his motivations." For Ben Schriever...
...would be nice to use pure hydrogen, but this is impractical because hydrogen is a gas that cannot be kept in the liquid state without extreme difficulty. Next best is to "liquefy" hydrogen by making it combine with some other element to form a conveniently liquid compound. Kerosene is such a liquid, but it contains too much low-energy carbon...
Boron compounds do not end the list of possible exotic fuels. Paintlike slurries of powdered aluminum or magnesium, suspended in some combustible liquid, contain a lot of energy. In the case of rocket motors, which do not depend on atmospheric oxygen, both the fuel and the oxidizer material with which the fuel combines can be varied. Nitric acid is popular because it is a convenient form of oxygen and yields additional energy when it decomposes. Liquid fluorine is theoretically the best oxidizer, but it is fantastically corrosive and hard to handle. Some material may be discovered that yields fluorine conveniently...
...meet this objection, Drs. Calvin and Sogo cooled their apparatus down to - 140°C., close to the temperature of liquid air, so that electron-yielding chemical reactions could not happen. Then they placed deep-frozen chlorophyll in a magnetic field and shot extremely high-frequency radio waves through it. When strong light was shone on the chlorophyll, some of the radio energy was absorbed. This proved to Dr. Calvin that chlorophyll exposed to sunlight contains free electrons, and is therefore capturing light energy by the layer-to-layer method. Nature's green plants. Dr. Calvin believes, have turned...
...Jean Erdman, was a wittily detailed examination of the love life of a voraciously modern woman and a hesitantly questing male. Leading Dancers Erdman and Donald McKayle defined the amorous counterpoint in elaborately postured movements grotesquely amplified by a corps of eight dancers and echoed by an alternately liquid and rhythmically spiky score...
