  2. Tek 6 • Do a PowerPoint over the following topic: What is a cloud chamber? How was it invented, and what discoveries did it make possible

  3. What is a cloud chamber? • Also called Wilson chamber , a cloud chamber is a historic device, used to make charged tracks originally cosmic rays in pre-accelerator times visible over a large volume. http://rkb.home.cern.ch/rkb/PH14pp/node29.html

  4. How was thecloud chamber invented? • The cloud chamber was invented c.1900 by C. T. R. Wilson. In the type devised by him, which is often called the Wilson cloud chamber, air or another gas is saturated with water vapor and enclosed in a cylinder fitted with a transparent window at the top and a piston or other pressure-regulating device at the bottom. When the pressure in the chamber is suddenly reduced, e.g., by lowering the piston, the gas-vapor mixture is cooled, producing supersaturation. http://www.infoplease.com/ce6/sci/A0812625.html

  5. what discoveries did the cloud chamber make possible? • Adrenaline: • (isolation of) John Jacob Abel, U.S., 1897. • Aerosol can: • Erik Rotheim, Norway, 1926. • Air brake: • George Westinghouse, U.S., 1868. • Air conditioning: • Willis Carrier, U.S., 1911. • Airship: • (non-rigid) Henri Giffard, France, 1852; (rigid) Ferdinand von Zeppelin, Germany, 1900. • Aluminum manufacture: • (by electrolytic action) Charles M. Hall, U.S., 1866. • Anatomy, human: • (De fabrica corporis humani, an illustrated systematic study of the human body) Andreas Vesalius, Belgium, 1543; (comparative: parts of an organism are correlated to the functioning whole) Georges Cuvier, France, 1799–1805.
