AI Thread Summary
The discussion centers on the A.P. French equation related to singing wine glasses, specifically regarding the constant β (beta). The value of β can be calculated using the formula β = 0.3 - 1.229 x 10^-4 x abs(965 - density of liquid). A linked document provides further details on this equation and its application. Participants share insights on the complexity of the equation and its relevance to the physics of singing wine glasses. Understanding this constant is crucial for accurately working with the phenomenon.

Hi everyone

I have been working with singing wine glasses and the A.P French equation - I was just wondering if there is a value or way to work out the value of the constant in the equation?

I have a basic understanding of physics but yeah haha...

Cheers guys

AP French Constant

The AP French equation is very complex and I am assuming the constant that you are referring to is β (beta).

If so, the value of β can be calculated using the equation:
β=0.3-1.229x10^-4 x abs(965-density of liquid)

This equation is discussed in the document I have linked below:

Hope this helps

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
