Since then, she has sung most of the roles written for lighter soprano, both lyric. and coloratura. In the process, she has come to be regarded by critics as one of the world's three or four operatic "superstars." She will soon make her debut with the Metropolitan Opera...
...real find here is the ballet score Appalachian Spring, presented for the first time on disc in the version for 13 instruments (strings, woodwinds, piano) originally written for Martha Graham in 1944. Lighter and leaner than Copland's later scoring for full orchestra, this interpretation is an exquisite way to rehear - or meet - one of the homespun classics of 20th century American music...
Unlike dirigibles and other lighter-than-air ships, the Aerocrane gets only 40% of its lifting capacity from its helium-filled sphere. The rest comes from the rotation of its wings, which can be pitched as they whirl around to control ascent and descent. This gives the chopper-balloon a distinct advantage over traditional lighter-than-air ships, which must drop ballast or spill their gas when taking on or unloading any cargo. Yet because of the buoyancy provided by its supply of helium, the Aerocrane should be able to loft heavy cargo much more efficiently than a conventional helicopter...
...poky Aerocrane probably will never be practical as a people mover, but it could be economically put to other uses. Arizona Senator Barry Goldwater, a strong advocate of lighter-than-air vehicles, is encouraging the Senate Aeronautical and Space Sciences Committee to study the potential of blimps, dirigibles and hybrid airships as bulk cargo transporters during hearings this summer. All American Engineering already foresees such chores for its Aerocranes as lifting logs out of remote timberland, unloading container ships that are too large to come into port, and delivering fully prefabricated houses directly from factory to home site...
...Museum of Science, the show is basic bring-the-kids. It has all the colorful optical illusions that I first encountered in the Tootsie Roll ads under "Metropolis Mailbag" in Superman comics: the same color seeming lighter or darker according to its background, a green, black and orange flag that makes you see red, white and blue when you look away. A prism breaks white light into the color spectrum, and a sodium vapor lamp turns everyone's skin yellow. There are lots of fun knobs to turn and fun buttons to push, and color TV excerpts from ZOOM...
