Thomson & Quartz Disk...
...notice in your issue of Sept. 19, p. 23, under the title "Other New Observatories," you have made a statement in which I am made to say that I do not see my way clear toward making the necessary fused quartz disk (meaning the 200-in. disk), etc. I am sorry that you did not consult me before making a statement which is not in accordance with actual fact. It imposes a burden upon me which I did not seek, of correcting inquiries. I have all along held that from the work which we have done in fused quartz...
Analogs of Professor Auguste Placard's flights toward the stratosphere above Switzerland are Dr. William Beebe's dives toward the bottom of the sea off Bermuda. Dr. Beebe, field agent for the New York Zoological Society, uses a bathysphere. 4¾ ft. quartz-windowed steel ball with walls 1½ in. thick. Its purpose is to withstand the pressure of deep sea water, whereas Professor Piccard's 7-ft. aluminum gondola was constructed to prevent its explosion in rarefied...
...biggest-telescope position. The old reason is California Institute of Technology's intention of building a 200- in. telescope in California, near Mount Wilson's 100-incher. Two factors delay Caltech: 1) Dr. Elihu Thomson of General Electric does not yet see his way toward making the necessary fused quartz disk which will be nearly as wide as a two-story building is high; nor has any other mirror-builder come forward with a sound plan for building the vast platter; 2) Caltech must wait until the securities which it owns appreciate in income and market value before spending large...
...joined the parade of corporations getting into the "next big industry": air conditioning equipment. Dr. Robert G. Guthrie, chief metallurgist of the Chicago utility, announced the invention of a new chemical compound which he calls "lamisilite." "Lamisilite" is a silicate like silica gel (which certain new air conditioners use), quartz, opal, beryl, tourmaline, garnet, mica. Like silica gel, the new material is highly hygroscopic- absorbs moisture, dehumidifies air. The mother ore of "lamisilite" is a trade secret. Victor Chemical Co., who will make the material for the gas-operated conditioners, knows of large deposits in North and Central America, some...
