WIRELESS WONDERS
“A Theatre of Wireless Wonders” was one of the attractions at a radio exhibition held recently in Chicago. Machines were demonstrated which made accurate measurements of distances like 1-10,000,000 th part of an inch, says the Sydney “Sun.” Rays of “cold-heat” -were transmitted in a beam, and blocks of ice melted in front of the audience, and a visible stream of electrons was precipitated at the rate of 150,000 miles a second. There were also amplifiers which built up sounds to millions of times their original volume, allowing flowers actually to be heard growing! Wireless beams were also sent out which froze the flowers into brittleness, so that they crumbled in the fingers. This juggling of atoms, including their measurement and velocity, forms a big part of radio research.
