...reasons for choosing 1957-58 as as Geophysical Year was the anticipation of great solar activity--sunspots, flares and "plages" many times the size of the earth--which occurs in roughly eleven year cycles. As long ago as 1946, scientists were looking forward to last year as another peak in the sun-spot cycle; they were amply rewarded, for both 1946-47 and 1957-58 turned in high sunspot peaks. Donald H. Menzel, Director of the Harvard College Observatory, and long a specialist in solar research, agreed that the Sun cooperated beautifully during its intensive examination. In fact...
Judged by unemployment alone, the U.S. is not. Industrial production is back almost to peak levels, and yet industry still has 20% unused capacity, along with 4,108,000 unemployed (6.1% of the labor force). There are other doubts about economic growth. After half a century of expansion at an average 3% annually, the real U.S. gross national product (excluding price boosts) has gained only an average 1.3% annually over the last five years...
...that he may be electable, he is given the chance to do a "photo feature." He selected a particular activity, or an aspect of Harvard life, and characterizes it by a series of pictures which are generally printed as a full-page insert. A successful feature can be the peak of a candidacy...
...Kozyrev shows a spectrogram with an unusual bright streak, and explains what he thinks happened. The reddish patch over the crater's central peak he believes was caused by volcanic ash shot out of the moon's crust. The dust settled quickly, since there is no air to keep...
...Kozyrev tells how he trained a 50-in. telescope on the moon on the night of Nov. 2-3 and took spectrograms of the crater Alphonsus. While he was watching, he saw the small, central peak of the crater lose its sharpness and turn reddish. By the time he changed the plate to take the next spectrogram, the peak was white again but much brighter than usual. A third spectrogram showed the crater back to normal...
