Hello all, I found this forum while searching for a specific formula (which I haven't found yet).
I'm doing a lot of geographic stuff for a web site, which has led to me dusting off some the knowledge I learned over 40 years ago but sadly have mostly forgotten (I blame Mr Richards for not teaching me properly:) )
Anyway, I'll have another search to make sure what I'm looking for isn't already here, but I'll be back...
Welcome to the forum! That is fine with me let's go beat the snot out of this Richard's fellow.
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
