A good little video for today!
 

Very cool, thanks!

Hi,

I like this Ramanujan formula:

It converges really quickly.

In engineering school, back in the coal burning days, the original 4-function calculators became
available. Most did not have a pi button.

A sufficiently good approximation of pi for any exam could be had taking the string 113355
Splitting it:? 113? 355?? and then dividing:
355 / 113 = 3.141593

And getting 6 digits or accuracy from two 3-digit numbers
is rather insane!? I always loved that approximation._,_._,_

24. Pi has a sacred bond with the circle. A circle’s angle
spans 360 degrees around its centre and it is a coincidence
that the number 360 is at the 359th digit position of pi.
