I agree with Linda - it's a bit of fun. Liked the idea of the 3 different planes A,B & C. Hadn't thought of that possibility at all yet. It certainly made me think..... Personally I only know 1 person who is a mathematics expert -however, I don't think he is on this forum. - The question is whether the concept of (see subject) is a simple one or can it be made as complex as one would like it to be. (possibly yes) In the latter case only .01 % (or less) of the population would be able to read and understand the formula for it. I think my wife Claire did right in trying to put the concept on a pin head. It surely is not easy to do and the result not perfect but attempting it anyway needs to be admired and enjoyed.
The main thing in my view is to understand the underlying concept - obviously a formula can help the process tremendously.
