...required for an electron to move from one point to another under the action of a high-voltage field. The electric field was obtained by the use of the 100,000-volt storage battery belonging to the laboratory and the timing of the electron was accomplished by a short wave oscillator. The frequency of the oscillator was obtained by the use of piezo-electric standards of frequency which were also developed in the laboratory and have come into great importance commercially in the control of the wave lengths of radio transmitting stations. From the measurements of electron velocity Professor Chaffee...
...Pasha held the grasshopping enemy at bay while trenches were dug along a mile long front. As billions of locusts swarmed and tumbled into the trenches paraffin oil was poured in and blazed. Latest reports were that the original locust offensive had been checked in Egypt, but a second wave was expected when eggs deposited in billions by locusts now dead should hatch. At each lay a single female locust deposits 8,000 eggs in a glutinous egg sac about the size and shape of an ordinary druggist's capsule...
...Association gave can only bring the tinge of the ridiculous to a serious matter that deserves the thoughtful attention of all Harvard men. The Square Deal Association's conduct of the matter has appeared to be one of riding into the spot-light of fame on a wave of public sympathy for the scrubwomen. Only when they declare their ball a success have they evidenced any touch of modesty...
Similarly with the ether highways of the radio world: the wave-bands assigned to different stations must be spaced across the radio spectrum to avoid overlapping, garbling of messages. Reducing the "width" of the wave-bands would make "more room...
...announced last week in London. If it lives up to its inventor's expectations, "room" may be made on the U. S. air for 3⅓ times the present number of stations (631); on Britain's air, for three times the present number of stations (20). Long-wave stations must now be spaced at least ten kilocycles apart...
