...Cruft Laboratory, among the numerous researches that have been under way, Miss Charlotte T. Perry, graduate student in Radcliffe College, and Professor E. L. Chaffee have completed a research on the absolute determination of the ratio of the charge of an electron to its mass. This research makes use of a direct measurement of the time 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...

...light did not exert pressure this ion and electron cloud would be spherical in form. But because light does press, sunlight forces the cloud into its egglike shape. The butt side is towards the sun. It is in that direction 30,000 miles thick and appears as the Zodiacal light. From the opposite side of the earth where the cloud's resistance to sunlight pressure is less it is squeezed a million miles or more from earth into a thin taper. That is where the Gegenschein glows. Through that taper the earth's atmosphere very, very slowly escapes...

...atom, tightest bundle of matter which man knows, would be a morning glory pod popping out its electron and proton seeds, if physicists had an electric current of sufficiently high voltage at their hands. General Electric jupiters and Westinghouse thors have produced 5,000,000 volts of static electricity for an instant's duration. Their passing flashes have been useful only to indicate the nature of natural lightning. General Electric's William David Coolidge two years ago succeeded in ramming 350,000 volts through three special vacuum tubes connected in tandem. He got the cumulative, cascading effect...

...centimeter of water, and four other items. From observation he has figured very closely the velocity of light, the drag of gravity, absolute zero (459.4 degrees below zero, Fahrenheit) and six others. By deduction there are seven derived constants, like the mass of the hydrogen atom, or of the electron. Then there are six experimental constants, and four conventional...
