   Diagonal of 1x1 square = Root-2. Ok.
   Diagonal of 1x1x1 cube = Root-3 !!!  Beautiful !!

Doesn't that not strike people as mathematically amazing! that the internal diagonal of a 'Cube' (1x1x1) = Root-3 !!!
I love the natural relationships with certain numbers, that can easily be proven/shown, and be so simple!   8)
GREAT!!  Good-ol basic maths can show/prove it all !!!...

Then I found out recently, that there is NO KNOWN correct formula, to calculate the Circumference of an 'Ellipse' !!   :palm:
You don't believe it... then look it up!!  Sigh...   Just lost faith in Maths again...   :box:

Of course there is a correct formula.  The relevant observation is found on this page: http://www.numericana.com/answer/ellipse.htm#elliptic

"There is no simple exact formula:  There are simple formulas but they are not exact, and there are exact formulas but they are not simple."

The one I like is phi, 1.6180339.....
In particular
phi^2=phi+1
1/phi=phi-1

Q: What does a maths graduate say?

A: "You want fries with that?"
