...Jackson, while not the first man to peer down the trachea and esophagus, perfected the circus sword-swallower's technique of throwing back the head so far that mouth, throat and windpipe or gullet form a straight channel through which a straight metal tube can be slipped. The tube which penetrates the windpipe to the lungs is called a bronchoscope. A slightly larger metal tube which goes into the gullet is Dr. Jackson's esophagoscope. At the tip of esophagoscope and bronchoscope is a small electric light by whose illumination the bronchoscopist can see any foreign body...
...known," as a result of work which had set him on the road to fortune, if not fame, 31 years ago. Mr. Marsh's profitable discovery was made in 1905. He fused a new alloy called Chromel-20% chromium, 80% nickel- which is still the only alloy or metal (except costly platinum) capable of offering prolonged electric resistance without burning out. Of this alloy or its variants are now made the wire elements which glow in electric stoves, heaters, curling irons, percolators, toasters, sterilizers, waffle irons, cigaret lighters, bed pads. Such an alloy is also used...
...astonishing degree French capitalism itself. It is a private institution owned by more than 40,000 stockholders. Yet it holds all of France's enormous gold hoard except that privately stored in mattresses and old socks. The French Government owns not a centime of monetary metal. The Bank of France has the sole privilege of issuing bank notes, banks the Government's money, is always one of the biggest creditors of the French Govern ment and has the power, often used, of shutting off Government credit when it does not like the Government's policies. Unlike Federal...
...glimpsed the four big satellites of Jupiter and wondered what they were. The mod ern art of splitting up light into its com ponent colors, which disclose the chemical nature of the source, depends on a little thing called the diffraction grating. This is a plate of glass or metal with 15,000 to 30.000 parallel lines accurately ruled across every inch of it. Each line reflects the light at a slightly different angle. It was with diffraction gratings that science learned that electrons were waves as well as particles, that beams of light were particles as well as waves...
Even with diamond-pointed ruling machines it is extremely difficult to rule hundreds of thousands of such infinitesimal lines accurately on hard metal or glass. Last week at the Washington meeting of the National Academy of Sciences (see above), Physicist Robert Williams Wood of Johns Hopkins showed how a brilliant scientist may adapt for his own use a technique worked out for a wholly differ ent purpose. At California Institute of Technology, Dr. John Donovan Strong has been coating telescope mirrors with a thin, even layer of aluminum by placing the glass in a vacuum tank, boiling the aluminum...
