The Foucault Pendulum illustrates the rotation of the earth. It is not constrained to stay in a fixed plane like a clock pendulum, but instead its ordinary pendulum motion is free to change direction ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

Living without gravity spells disaster for the human body. Even a few weeks in microgravity can lead to issues with circulation and vision; over the longer term, the complications compound even ...
