Aircraft designers have studied the flight of birds only superficially. But with slide rule and logarithm they have come close, independently, to the mechanisms that keep the bird on the wing. The masters of machines that can outfly any bird for speed or distance must admit that a bird is, in a structural sense, a small and amazingly efficient living airplane. John H. Storer explains all this in a new book, The Flight of Birds (Cranbrook Institute of Science...
...book, "Tables of the Bessel Functions of the First Kind of Orders Sixteen through Twenty-Seven," looks much like a mammoth logarithm table and was compiled by the College's Computation Laboratory. All the mathematicians had to do was correctly adjust their "Mark I" calculator and turn...
...four-minute mile is possible. So reported Dr. Alfred W. Francis, research chemist and amateur trackman, in Science. Using a plot of average speed in meters per second against the logarithm of the distance, he drew a graph of 17 record marks, from 200 meters to 10 miles. The point for one mile was well below Arne Andersson's present record: 4:02.6. Dr. Francis, whose own record for the mile is 4:38, figures...
