...Constant divided the flow of energy into "smallest" bursts (the "quantum" of the quantum theory). Gamow suspects that this missing length may turn out to be about 10 -13 centimeter (one ten-trillionth of a centimeter). A length close to this shows up as the radius of an electron, and as the effective range of forces in the atomic nuclei. "All kinds of physical considerations," says Gamow, "become senseless when we try to apply them to distances smaller than 10 -13 centimeter...
...early calculators contained gears, scales and measuring devices. The best modern ones are built chiefly of electron tubes which give a simple "yes or no" answer when stimulated by electrical impulses. This is roughly what the neurons (nerve cells) do in the human brain...
...Ultrafax is no table-top trinket. In the cut of the receiving apparatus, a "flying spot" of light is in the cylinder at the upper right. The film runs through the square camera box below it. The rest of the big cabinet is full of electron tubes and "monitoring" equipment. The pretty girl, the clock and the book are decorations...
...This is THE meter: the standard length in terms of which all the world's measurements are defined. Even men who speak in pounds or poods, kilometers or versts, acres or mu depend ultimately upon the meter bar in Paris. The subtler units of measurement, such as dynes, electron-volts and curies, are based...
...electricity, about ten a second, pass rhythmically over the top of his brain. These "alpha waves" have been used to diagnose various brain conditions, but for a long time no one understood their function. Now, said Dr. Hoagland, many neurologists believe that they are "scanning devices" like the electron beam that scans the image in a television transmission tube...
