...roll-like an ordinary Kodak. A fresh film was moved into position by pulling a lever. When in mock combat, the student tried to get his sights on his opponent and "fire" by pulling a trigger-the developed film showed the concentric rings of a conventional target plus the photograph of the "enemy" plane. These pictures were developed and graded like examination papers at school-for correctness of lead was easily checked from the picture. I doubt if such a camera was ever used at the front. The pictures were about 1¾"x 2¼" in size...
...year 1932 was one of the best comet years in recent history when 14 were either discovered, or reappeared after a long absence. On August 9 Whipple observed a new comet on a photographic plate. The photograph was taken with a one-inch lens and the body can be discerned on a clear night with the naked eye. The comet was seen a few hours earlier by Peltier, a variable star observer in Ohio, who saw it without a telescope. In California a Japanese vegetable grower, named Sase, who was busy with his lens saw it also with the result...
...been taking recently, Stevens said, "I am not prepared to go into this question. Thus far the experiments have been justified by necessity for military prepareduess. From an altitude of 2,000 feet a section of the earth two miles in diameter may be illuminated enough to be photographed, and night pictures may now be made with certainty. With special emulsions, we have been able to photograph over the earth's surface for a distance of over 330 miles. Still more sensitive emulsions are being made by laboratories, and will be tested in the near future...
...major biological advances of 1932. Boasted he last week: "We built for Professor Edmund Newton Harvey of Princeton a centrifugal microscope which allows living cells to be studied while whirling at the ratio of 10,000 revolutions a minute. Dr. John Belling of the Carnegie Institution, using photomicrographic equipment, photographed the gene, the tiny particle which is believed to control heredity. Dr. Ralph Walter Graystone Wyckoff of the Rockefeller Institute used invisible ultraviolet light to photograph the growth of living cells under the microscope...
What Chancellor-elect Chase plans for N. Y. U. he did not announce last week. He will, perforce, ponder its growth in 101 years, from the time that Samuel Finley Breese Morse there developed the telegraph and Professor John William Draper took the first photograph by sunlight. In 22 years under Chancellor Brown the enrolment grew from 4,175 to nearly 40,000 (including part-time students); the faculty from 282 to 1,800; the schools and colleges from eight to 12, including the important Graduate School of Business Administration. N. Y. U.'s endowment grew in proportion...
