Tube Quotes - page 3
In the dark ages before the invention of the electronic vacuum tube there were many legends of living statues and magic pictures. One of the commonest devices of sorcerers and witches was the model of an enemy which somehow embodied his soul, so that injury to the model would be reflected by suffering or death of the original... Idolatry, witchcraft and other superstitions are so deeply rooted and widespread that it is possible that even the most detached scientific activity may be psychologically equivalent to them; such activity may help to satisfy the desire for power, to assuage the fear of the unknown or to compensate for the flatness of everyday existence.
William Grey Walter
In the machine for a new use of gunpowder, which is described in the 'Acta Eruditorum' for the month of September, 1688, the first desideratum was, that the gunpowder fired in the bottom of the tube AA should fill the whole cavity with flame, so that the air might be entirely expelled from it, and the tube remain a perfect vacuum beneath the piston BB. But there it was mentioned, that the desired effect could not be sufficiently attained... But hitherto such attempts have been in vain; and always, after the flame of the gunpowder is extinguished, about a fifth part of the air remains in the tube AA.

Laplace made many important discoveries in mathematical physics... Indeed, he was interested in anything that helped to interpret nature. He worked on hydrodynamics, the wave propagation of sound, and the tides. In the field of chemistry, his work on the liquid state of matter is classic. His studies of the tension in the surface layer of water, which accounts for the rise of liquids inside a capillary tube, and of the cohesive forces in liquids, are fundamental. Laplace and Lavoisier designed an ice calorimeter (1784) to measure heat and measured the specific heat of numerous substances; heat, to them, was still a special kind of matter. Most of Laplace's life was, however, devoted to celestial mechanics.

As collage technique replaced oil paint, the cathode ray tube will replace the canvas. Someday artists will work with capacitors, resistors, and semiconductors as they work today with brushes, violins and junk. There are 4,000,000 dots per second on one television screen, just think of the variety of images you can get. It's so cool. It's like going to the moon.
Nam June Paik
Roll a ball under your hand on a table and roll a pencil in the same manner. What you feel are "point" and "line" bearings. But to understand what mechanics mean by a surface "bearing," grasp a pencil in your hand and use your other hand to make it turn as a piece of shafting. Now, the lower half of the shaft is supported everywhere by contact with your hand - the upper half is not supported, merely covered. The advantages of ball and roller bearings were obvious many years ago to mechanical people... Solid steel rollers, being inflexible, were not satisfactory at that stage, but a Hyatt flexible roller bearing was different. We had something. Our spirally wound tube roller had a springlike quality, yielded to irregularities caused by poor manufacture, thus making automatic adjustments between housing and bearing.
