...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...
Fortunately, nature has provided a chemical element, boron, which can be forced with some difficulty to improve on carbon's performance. Boron has a high heat of combustion (25,000 B.T.U. per lb.), and it forms compounds that contain more energy-rich hydrogen than most hydrocarbons do. The heat of combustion of diborane (B2H6), for instance, is 31,000 B.T.U. per lb., almost twice as good as kerosene...
Some of Diamond's colleagues also heard from last week: ¶J Alan Hovhaness' Easter Cantata got its first New York concert performance by the National Orchestral Association under Guest Conductor Newell Jenkins. Mystically described by Armenian-descended Composer Hovhaness ("The vocal element ... is the sun; the other sounds are the planets"), the work moved with melodic simplicity, derived its main effects from the repetitive. Oriental-sounding accompaniment which has helped to distinguish Hovhaness' output from more technique-tortured works of his contemporaries. ¶J Italian Composer Riccardo Malipiero's 45-minute Sinfonia Cantata was premiered...
...Luneville in the French duchy of Lorraine. Historians guess that La Tour went to Rome as a young man, learned there the technique of Caravaggio's dramatically spotlighted paintings. Back home he refined his work to make light itself not only a dramatic highlight but the modeling element and dramatic center of his painting...
...command the southern reaches of the Communist empire. Everywhere, Radford argues publicly and privately for the alltime-peacetime-high defense and foreign military assistance budget of $43.3 billion (58? in every U.S. tax dollar) designed to give muscle to U.S. commitments to 43 friendly nations as an essential element of U.S. security...
