... (overall) charge on a material is zero. However, when two materials are rubbed together, electrons may be transferred from one to the other. One material ends up with more electrons than normal and the other with less. So one has a net negative charge, while the other is left with a net positi ...

To verify it, in the 50s, he conducted a large series of experiments with gyroscopes and found that the weight of the gyroscope depends on the angular velocity and the direction of rotation [1,2]. Although the observed ...
