The Townâs history is documented in the Bedford collection at the Bedford Public Library. Visitors are drawn to view historic sites including homes, the Old Burying Ground, The Wilson Mill, the Job Lane House and the original Bedford Flag that was taken to the battle of Lexington and Concord in 1775.
The phenomena of atmospheric electricity are of three kinds. There is the electrical phenomena of thunderstorms and there are the phenomena of continual electrification in the air, and the phenomena of the polar Aurora constitute a third branch of the subject.
The atmosphere is actually a weak conductor and if there were no sources of charge, it's existing electric charge would diffuse away in about 10 minutes. There is a 'cavity' defined by the surface of the Earth and the inner edge of the ionosphere 55 kilometers up.At any moment, the total charge residing in this cavity is 500,000 Coulombs. There is a vertical current flow between the ground and the ionosphere of 1 - 3 x 10-12 Amperes per square meter.The resistance of the atmosphere is 200 Ohms. The voltage potential is 200,000 Volts.he only things that could cause this is the shrinkage of the earth or an increase in the velocity of light. Neither has been observed and further, the SR that is under constant monitoring as well, is still stuck at 7.75 CPS as it was in the past. The earth is not shrinking.
