Electrical Experimenter (07:10) February 1920

Hugo Gernsback, editor

"As Professor Einstein so aptly put it in a recent interview: "Take this house and remove the earth to an infinite distance. What happens? The house as well as the objects contained therein will weigh nothing out in space. Our bodies would float in the air providing air was retained in the house. We could just as well walk on the ceiling as along the sides and bounce from ceiling to the floor; it would all be the same. For in space there is no up or down, and the word 'weight' has no meaning."
This issue of Electrical Experimenter is from February 1920. The cover story is “Suspended Gravitation.” The issue also contains an interview with rocket scientist Robert Goddard, two articles on the Audion tube, how Becquerel discovered radioactivity, vacuum tube circuits, and making fat people thin with electricity.
