...drum will hold 4000 in sequence, might read: "select the Number in A-1 and add to it the Number in B-2 and put the sum in C-3." Such a command can be given and the work accomplished by the computing section of the machine every four thousandth of a second...
...discovered in mice. Last week a five-man Columbia University team reported that it had succeeded, after twelve years of work, in isolating, identifying and photographing (in an electron microscope) a virus that causes breast cancer in mice. The virus is so powerful that an injection of eight one-thousandths of a gamma (a gamma is one-thousandth of a milligram) produced cancer even in male mice. Next step, already started: trying to make mice immune to the virus...
Measured in electrical engineering terms, the neurons are only one-thousandth as fast as vacuum tube relays, but they require much less space and much less power. Professor McCulloch estimated that if a calculating machine had only 10 million vacuum tubes (the brain has about 10 billion neurons), it would take the power of Niagara Falls to operate it and the Niagara River to keep it from overheating. The brain is cooled by a comparatively small river of blood. When awake and in full operation, it raises the temperature of a pint of circulating blood one-half degree a minute...
...TIME, April 19, a statement was made in the article, "Little Black Box," that a microvolt is one-thousandth of a volt...
...State Hospital by applying his electrodes to five* points on their bodies. He also studied 80 normal people. The difference between the amount of electricity produced by normal people and by schizophrenics was startling. Readings from the schizophrenics were very high, averaging around 65 microvolts (a microvolt is one-thousandth of a volt); normal people never sent the readings higher than about eleven microvolts. As the insane patients improved under treatment, their electrical readings fell closer & closer to normal. But if they stayed sick, their electrical marks stayed high...
