Janice, my sister, had been pestering her husband, a carpenter, for more than a decade to build a screen door for the kitchen.
One day, to her delight, he built and installed one in less than two hours. It was both practical and pretty. She glanced towards the front door and wistfully remarked that one would look good there, as well.
"Are you kidding?" he gasped. "You can't just whip these things up, you know. It takes ten years to build a door like this."
C.T.R. WilsonDied 15 Nov 1959 at age 90 (born 14 Feb 1869).Scottish physicist who shared (with Arthur H. Compton), the 1927 Nobel Prize for Physics for his invention of the Wilson cloud chamber, which became widely used in the study of radioactivity, X rays, cosmic rays, and other nuclear phenomena. His discovery was a method of rendering visible the tracks of such electrically charged particles. It is based upon the formation of clouds, which develop when sufficiently moist air is suddenly expanded, thus dropping the temperature below the dew-point. Thereafter, vapour condenses into small drops, formed round dust particles, or even, an electrically charged atomic particle. The formation of droplets is so dense that photographs show continuous tracks of particles travelling through the chamber as white lines. |
