AI Thread Summary
The Cavendish experiment remains valid and has not been debunked, as it can still be replicated today. A recent attempt to challenge it was dismissed as pseudoscience, primarily due to flawed comparisons between unrelated scientific values. The discussion emphasized that engaging with flat Earth proponents is often futile, as they tend to distrust established evidence. The original claims were deemed to lack a basic understanding of physics. Overall, the thread reinforced the integrity of the Cavendish experiment against unfounded criticisms.

TL;DR Summary
Someone showed me this and I wanted to know everything that's wrong about it.
A flatearther sent this to me a few months ago. Dude actually thought this... "project" would convince me. I don't subscribe to conspiracy theories at all, but my knowledge of science is very, very modest, so I can't personally scrutinize it properly. Would anyone be kind enough to help?

EDIT: Forgot the link, lol:

It's a waste of time analysing such things as they are generally nonsense.

Welcome to PF.

The Cavendish experiment has NOT been debunked, and can be repeated today.

That is a list of possible distractions that, then and now, play no part in the experiment. The list was constructed by a non-scientist, acting as devil's advocate, with the aim of muddying the water of science, with pseudo-science.

Any work that seriously compares two values with different dimensions (Newton's ##G## and whatever nonsense Spear's ##Ge## is supposed to be) and declares them "very close" can safely be dismissed as the work of a clueless poser. Is 1m "very close to" 1kg? Is 1km "very close to" 1kg? What does it even mean to compare a distance to a weight? If it didn't occur to anybody involved in the publication of that paper to ask the equivalent question about ##G## and ##Ge##, nobody involved has even the most basic grasp of physics.

Don't waste your time arguing with a flatearth person. They will simply not trust your evidence and conclude its all a conspiracy theory to hide the flatness of the Earth.

Closing thread, thanks to everyone who contributed here.

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
