One of the more precise pendulum experiments was performed in 1990 by Tom Kuusela. Kuusela found no effect to within 1 part in 4 million.

Paralleling the Cavendish experiment, the apparatus mitigates convective forces from reflectors heating to provide an ...

The experiment is even more fascinating when considered globally. Because the Earth is a rotating sphere you will see wildly different effects from a Foucalt’s Pendulum in different parts of the ...

PROF. GREENHILL gives currency to quite an erroneous idea, in last week's NATURE (p. 50). He says “in the Foucault experiment of the pendulum which shows the rotation of the earth, the slightest ...
