At the end of the 1600s, Newton proposed the universal law of gravitation: that every particle attracts every other particle in the universe with a force (F) determined by their masses (M) and the ...

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed ...

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental nature of gravity still eludes our best minds - but those ...

Last week over in Twitter-land, Philip Ball asked an interesting question: I’ve written a fair bit about historical science, and read more than I’ve written, so this question stuck with me, and seems ...

(via Steve Mould) The cavendish experiment shows that even the very week force of gravity can be seen between two room scale objects. Even with the naked eye.

New measurements of the gravitational constant confirm that the official value needs to be increased and, as John Moore reports, could explain what went wrong in a previous experiment. Ever since ...

Gravity is the weakest of all known forces in nature - and yet it is most strongly present in our everyday lives. Every ball we throw, every coin we drop - all objects are attracted by the Earth's ...

IN the last number of the Proceedings of the Royal Society (vol. xlvi. p. 253), I have given an account of the improvements that I have made in the apparatus of Cavendish for measuring the constant of ...

WEST LAFAYETTE, Ind. – Researchers have levitated a tiny nanodiamond particle with a laser in a vacuum chamber, using the technique for the first time to detect and measure its "torsional vibration," ...
