...months Prof. Piccard had been talking of stratosphere ascents in which the lifting power would be provided not by one big balloon but a cluster of small ones. It was his theory that with such an outfit he could keep on ascending until some of the balloons burst (because of the diminishing outside air pressure). Also, he could descend at will by putting several balloons out of commission with a pistol. He thought 2,000 four-foot rubber balloons would be enough for a record flight. Last week's ascent, using only 80 balloons, was in the nature...
...bright group of the Pleiades, near the celestial figure of amorous Orion, has been a source of wonder and speculation to shepherds and seers since the dawn of history. Telescopes reveal thousands of stars in the cluster, moving away from Earth at six miles per second (present distance: nearly two quadrillion miles). To Babylonians the naked eye stars were ''The Many Little Ones," to American Indians "The Seven Brothers." In some folklore they are called "The Seven Who Now Are Six.'' as though an ancient memory persisted that the dim star, which can be seen only...
That the seventh Pleiad is indeed a variable star was reported last week by Harvard Observatory. The cluster is draped in a veil of diffuse nebulosity which may vary the brightness of certain stars by interposing streamers of varying thicknesses. Observations by Dr. William Alexander Calder disclosed that in a year the seventh Pleiad, now called Pleïone, had diminished by one-sixth of a magnitude in brightness. It cannot have been decreasing for very long at this rate, otherwise it would have been the brightest star in the sky less than a half century ago. But the fact...
...Fifteen years ago the vast bulk of the Metropolitan Museum, the cluster of dealers along Fifth Avenue and 57th Street, and pre-auction exhibits at the Anderson and American Art Galleries (since combined), were about all the art that a visitor to Manhattan could see. Since then, thanks to public-spirited tycoons, the art map of New York has spread and sprouted richly. Today an art-conscious visitor should not leave Manhattan without a pilgrimage that will cover more than ten miles, take him into some 100 institutions. Among the most important stops...
...there for two days, like black beetles stuck in cake frosting. In the Straits of Mackinac 50 miles south the car ferry Chief Wawatan cleared a path of blue water for four freighters, led them across Lake Michigan to Escanaba, returned to the Straits to break ice for a cluster of 38 more. At week's end the wind changed to the south. Through softer ice the freighters Frontenac and Peter White pushed ahead of the others out of Whitefish Bay and crossed Lake Superior to Duluth. They passed the W. D. Rees, eastbound from Superior with the first...
