Twenty-five Yardling oarsmen were X-rayed at the Dillon Field House yesterday in a long-range experiment to prove conclusively that rowing does not affect the size of the heart. Guinea pigs for the tests, these Freshmen will submit to similar X-rays semi-annually throughout their four years of college...
Denied the use of human subjects, researchers make most of their cancer experiments on animals. One vicious type of animal cancer-"mouse sarcoma 180"-is highly resistant to such ordinary methods of treatment as radium and X-ray therapy. In very few cases does it dry up and disappear spontaneously. More important, mouse sarcoma 180 is a reliable subject on which to test the effectiveness of various treatments for human cancer...
Lacing the eastern seaboard like a big X, one of whose axes runs from Chicago to Miami and the other from New York to Houston, Tex., Eastern Air is the fourth biggest U. S. airline and the only major domestic one to make a sizable profit in 1937-$270,000 before income tax deductions. This makes it a choice business property, but North American Aviation found possession embarrassing because the Air Mail Act of 1934 forbids one company both to have airmail contracts and to manufacture airplanes. North American is the only U. S. concern to have gotten away with...
...last theorem of French Mathematician Pierre Fermat, laid down in the 17th Century states that there are no solutions to the equation: x n +y n = z n , n being a power greater than the square and x, y and z being whole numbers which are not zero.* Fermat wrote on the margin of a book that he had hit upon a proof of the theorem, but that there was not room enough on the margin to write it out. He died before he wrote it anywhere else that anyone knew of. The theorem became celebrated in the history...
Last week Herr Krieger made headlines once more by announcing that he would reveal the values for x, y and z which would solve the Fermat equation. They turned out to be 1,324; 731; and 1,961. He would not reveal n-the power-but said it was less than 20. An astute reporter from the New York Times, no baby in mathematics himself, pored over this equation: 1,324 n +731 n =1,961 n . The reporter saw that the first number raised to any power at all would end in either 6 or 4, the second raised...
