Talking Casimir effect

I don't know what's exactly the Casimir effect. Some materials in web tells that it's "the phenomenon of the occurance of attractive force between two metalic panels which close to each other in very small distance".
If it is that, then someone who can explain why atoms can form that metalic panel can explain Casimir effect.

Please use a new thread to ask new questions.

I'm not quite sure what queston you are asking. Here's a link to it.

(The article mentions the zero point energy to help explain the process. I don't like anything that invokes the ZPE from the standpoint that any measurement of the ZPE that is not 0 is really a measure of our inability to correctly calculate it. I may have to eat those words if at some point someone experimentally measues it to be non-zero. But for now the question of a non-zero ZPE is an open one.)

Please give the article a read and ask any specific problems that you have with it.

I'll have to bug mash again.

Here's the link: https://en.wikipedia.org/wiki/Casimir_effect

I don't think Neila is complaining about the link not working
(it works fine for me)
He is saying that he can't access Wikipedia.

Here are a couple of links to other sites I have found,
hopefully one will be ok for you:

https://www.scientificamerican.com/a...casimir-effec/

https://physicsworld.com/a/the-casim...-from-nothing/

Talking

If the true cosmos is a 4D space, then what's the use with even complicated mathematical calculation in 3D space? "To discuss the gap between math and physics?"

Please keep the X4 stuff in the X4 thread. Thanks.
