We have a beautiful theory that puts each of nature’s forces into a single, neat package. The whole of it can be summed up in a single line of very compact—and for most, including me, incomprehensible ...
The Eagleworks team obtained EMDrive experimental force measurements in the torsional pendulum in a hard vacuum (~5.0×10^-6 Torr). Paul March included their last null-thrust test that ran the RF amp ...
According to Reppy's experiments, which are the subject of a Viewpoint by John Beamish (University of Alberta) in the latest edition of APS Physics, the period change may have had nothing to do with ...
When oscillating, the pendulum slowly shifts between torsional and vertical modes of oscillation. When stretched down, the spring applies a torque to the mass to help it unstretch. When compressed up, ...
