The experimental work of the electromagnetic method was done at the University of California under blond, boyish Dr. E. O. Lawrence; on diffusion, at Columbia under Dr. H. C. Urey. By 1943, before the experiments were completed, vast plants to carry out both processes were being constructed at Oak Ridge...
Mysterious Corona. Last week's eclipse, whose maximum duration (in Greenland) was 76 seconds, raised to a bare two and a quarter hours the total recorded observation of eclipses by modern science. Much of the scientific interest centers around the corona, which extends for millions of miles from the...
A bit of simple mathematical calculation in each case gives the right answer. The Liebers go on to discuss more complicated questions, such as the relation of mathematical philosophers to practical inventors. For example, practical Marconi had to get the idea that a wireless message might be sent before he...
Einstein in recent years : to provide a fundamental explanation for both gravitation and electromagnetic attraction.
Electromagnetic fields so far are inde pendent, apart from other phenomena, do not satisfy the scientists' yearning for fundamental unity. The mathematical struggle is not to handle them in practical terms, nor to add further dimensions to space-time in order to account for them; it is to devise...
