Sweet thread :D

As a fan of statistics, I'm gonna go with the Phi-coefficient, aka golden ratio. Tau is great too :hyper:


Btw if you like Pi, you NEED to check out this vid:

What Pi sounds like

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 φ2​-φ-1=0, so:
(-(-1)+((-1)2​-4(1)(-1))0.5​)/2(1)=(1+50.5​)/2
φ= 1.618033...
φ-1​= 0.618033...
φ2​= 2.618033...
Mindblowing!

:D

You use e in statistics, too.:hyper:

For instance, normal distribution:
f(x)=(σ(2*π)0.5​)-1​*e(-(x-μ)/2σ)2​
 
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.

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.
