...more than 30 billion) were free electrons and were multiplied by a billion and again by a billion, all those electrons would weigh just about one ounce avoirdupois. And yet one of those almost weightless electrons, a negative charge of electricity, as it shoots from the cathode of an X-ray tube or from the filament of a radio tube engraves its path on metal...
...high speed, broader for slower moving ones. This is a phenomenon noted in Professor Floyd Karker Richtmyer's physics laboratory at Cornell University and announced last week. One of his graduate students, Dr. P. H. Carr of Gaffney, S. C., had noted how pitted the metal targets of X-ray tubes became after long electronic bambardment,* and inferred that flicking light also left its invisible mark. To bring such marks, if existent into sight meant long trials of various reagents on such battered metals. In the end he found that mercury vapor "developed" electronic engravings on gold, iodine...
...X-ray tube the cathode shoots a stream of electrons at a hard metal target. The electrons heat up a spot of the metal so that it gives off invisible light rays, the X-rays...
...Coolidge employs four means of studying the skulls: the voluminous literature on the subject, x-ray pictures, scale photographs, and comparative measurements. He devotes the major part of his study to the skull, as is the custom in scientific research. He studied over 400 of them besides examining many hides and skeletons which also show great variation and are of accessory value in classification...
...Kirksville, Mo., gunmen accidentally shot Mrs. William Wilson through the left breast. She did not die. An X-ray showed that her heart was on her right side...
