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 ...
In the effort to unify the gravitational theory of general relativity with the quantum theory of the very small theoretical physicists explore a lot of wild ideas. One of these is the idea of higher ...
Along with gravimeters and torsion balances, pendulums can be used to measure gravitational force. The period oscillation of the pendulum can be used to measure gravitational acceleration, and in turn ...
