Well sorry to have to break it to you Bear but mate it wasn't invented it is a basic mathematical calculation that is infinite - almost like a law of physics you might say. It is a most important mathematical figure use in so many applications least not I wouldn't wonder used for calculating inter planetary shots.

But I do stand to be corrected.

Dinesh I think had it first up with Euclid I have 3.1415 embedded in my mind as reference for when I used to work out the rolling distances of road wheels Gary's illustration shows this perfectly and is the perfect way to know how it actually works - those crafty Hoosiers!!.

I saw some maths bloke on TV the other day quote it to 1000 decimal places and he was a visiting American mathematician who was matched by an Aussie fellow too - just amazing

No where in my post did I ever say or indicate pie was invented, No where.

Correct, I think John mistook you for the OP who did ask the question.
It was Kf10

Let us not forget that "other" irrational number phi (Φ or φ) or the Golden Ratio 1.6180339887

Some claims are made that Pythagoras (ca. 570-495 BC), the Greek sculptor Phidias (ca. 490-430 BC) and others were aware of "Natures Rule", but it wasn't until 1597 when Michael Maestlin was credited with making the first known calculation.

The Fibonacci sequence is also an approximation to phi, read more on his question about rabbits. Fibonacci sequence

This is a good watch.

There has been a new record for Computing pi.
Quote:
There are some 400 technical talks lined up for next week’s GPU Technology Conference (GTC), but few will be as topical as Ed Karrels’. The Santa Clara University researcher announced today – on Pi Day, which corresponds with 3/14 on the calendar – that he’s just broken the record for calculating pi, taking the classic ratio to eight-quadrillion places right of the decimal.

What can I say Bear? I am so sorry for my idiot comment I do apologise most profoundly obviously in one of my gung ho episodes and not paying enough attention.

Maybe I should take a break from posting as yesterday itself was a day I should have stayed in bed - at very least away from my machines

ICit...... no way, as long as those of us who know we do not know everything are here posting, that gives hope to those who know much more ... I'm one of the group, any one of use knows something no one else knows.

I have relearned something thanks to Golden ( Angle of Repose). Very interesting when one reads from complex things that man builds to insects little building projects.
Thanks Golden.
My three brain cells are not able to absorb the complexities of
pie at this time. I'm still working on 2+2=4 except in politics.
