It's the 306th anniversary of Leonhard Euler's birthday today. Not only my hero also my avatar. For those of a mathematical disposition who haven't heard of him google some of his work and boggle at his command of the subject. For those who think they have the ability to reinvent mathematics stay away from him: you're not fit to wipe his arse.

I wonder if Euler had similar around.

Math. Not even once.

Yay for math nerds!

Below is a quote from Sandokahn in the flat earth believers forum. It is part of one of two responses to this thread. Why he posted this in a thread in which only a select few can reply is anybody's guess. Have a read through the post and see what you think.
Here is a formula which the conspirators missed while inventing Euler's work (I discovered this formula back in 1998; it makes any and all logarithm tables obsolete; LN v = natural logarithm of v):
LN v = ((2 +{2+[2+...(2+ 1/v + v)^1/2]^1/2}^1/2))^1/2 x 2^n
n+1 parantheses to evaluate  in the last parenthesis we substract 2 and take the square root one last time (n+1), before we multiply the result by 2^n
For v very large, we can omit the term 1/v
Example LN 9999999999 = 23.02585093 (8 significant digits)
For our formula we will use n=12
The first parenthesis 2 + v (where v, of course, is equal to 9999999999), and we calculate the square root, (2 + v/2)^1/2 (n=1)
We add 2 to the result, and calculate the next square root (n=2), and so on, for n=12 we will obtain: 2.000031602
So for n=13 (12 + 1, n+1), we substract 2 in the last parenthesis, and calculate the last square root, obtaining:
5.62154783 x 10^3
We multiply by 2^12, that is 4096 and get the final excellent approximation:
23.02585991

Leonhard Euler sounds like a porn name. Are you sure he's famous for maths?

Oh yes.
Your being an engineer I thought you would have heard of him. But it may be your impish sense of humour. ;)

Euler was a wise man.
