I don't think Cavendish measured the Newtonian force. I believe this can be proved either by analyzing his actual data and/or duplicating the experiment with a well-designed test. What do you think?

I seem to have missed that lecture, can you fill me in on who Cavendish was?

Same... What's it all about?

This is great! I like tangler.

I missed that lecture too. I studied the experiment on my own. It is really simple and fun. Cavendish suspended a wooden beam (2 meters long) by a  copper wire and hung lead weights of 2 inch diameter on each end. He then brought heavier weights near the pendulum and measured the oscillations of the pendulum arm. He then computed the mean density of the earth.

My humble opinion is that Cavendish's pendulum never moved under the influence of the Newtonian force because Newton's force is occult and occult does not exist in nature. Professional physicists disagree with this. So I have been trying to find a good test to try when duplicating the experiment to verify if Cavendish did or did not measure the Newtonian force.
