Sweet thread As a fan of statistics, I'm gonna go with the Phi-coefficient, aka golden ratio. Tau is great too Btw if you like Pi, you NEED to check out this vid: What Pi sounds like http://youtu.be/wK7tq7L0N8E

Very good. For those that haven't heard it..... there are 10 types of people in the world. Those that understand binary and those that don't. Best maths joke ever.

A fascinating fact about φ is that its inverse is 1 less than itself, and its square is 1 more than itself. Knowing that, you can say φ[SUP]2[/SUP]-φ-1=0, so: (-(-1)+((-1)[SUP]2[/SUP]-4(1)(-1))[SUP]0.5[/SUP])/2(1)=(1+5[SUP]0.5[/SUP])/2 φ= 1.618033... φ[SUP]-1[/SUP]= 0.618033... φ[SUP]2[/SUP]= 2.618033... Mindblowing! You use e in statistics, too. For instance, normal distribution: f(x)=(σ(2*π[SUP]0.5[/SUP])[SUP]-1[/SUP]*e[SUP](-(x-μ/2σ[SUP]2[/SUP][/SUP]

An infinite number of mathematicians walk into a bar. The first one says "I'll have a pint," and then each next one says "and I'll have half of what he's having." The bartender says "You're all idiots!" and pulls two pints. What does a frustrated mathematician say to his children when they misbehave? "If I've told you n times, I've told you n+1 times!" How do you insult a mathematician? Tell him his brain is smaller than any ɛ>0.
