More successful and profitable than attempts to create gold from mercury is the actual creation of electricity at Hartford, Conn. The Hartford Electric Light Co. has been using a mercury-vapor turbine to run its generators since 1923. That turbine was shut down while last week a second was prepared for operation. William Le Roy Emmet of General Electric Co. invented and developed the machines. General Electric built them...
Student Pitt measured the conductivity of various samples of grain and lumber. These he then dried in an oven, collecting the vapor in an absorbent material which he weighed before and after the baking. This is the way dealers grade their goods. Thus the researcher obtained figures on moisture content and electrical conductivity. These he correlated into a chart. So much electrical resistance meant so much water...
...rust ate through a commonplace-looking tank and something began to escape with a faint hiss. The murderous invisible thing that stole forth was phosgene, almost imperceptible war gas. Two girls were fishing from a rowboat in the harbor nearby. When the air surrounding them became charged with phosgene vapor in the minute proportion of one-half gram per cubic yard they went suddenly limp, as the poison acted on their lungs. Invisible swords in the hands of cowardly assassins would not have been so quick, so deadly...
...consists of 100,000 photographs showing the tracks of about 1,000,000 atoms. The atomic trail is infinitesimal, a narrow path (usually straight but sometimes bent as though the atom had trespassed too close to some minute object which had repelled it) made of the same water vapor that forms the clouds. Occasionally some dizzily dashing helium atom hurtling through the hundreds of thousands of normal atomic citizens in the air crashes kerplunk into the nucleus of one of them. Only 30 such collisions occurred in all the 1,000,000 trails recorded by Professor Harkins...
Another feat was to photograph and thus make visible atomic disintegration. How he aid so he demonstrated to the American Chemical Society at their 1926 meeting in Los Angeles. The scientists there knew that in moisture-laden air invisible particles of dust collect moisture until they become visible water vapor. Professor Wilson theorized that ionized molecules in a dust-free, moisture-logged receptacle would also provide foci for water condensation. Into such a chamber he shot alpha particles from an x-ray machine. Drops did collect on the alpha particles...
