Pi Day is March 14th, ie 3.14 as in the first three digits of the mathematical constant pi. (3.14159...)

And in Oz, Pi Day has fallen over into the Ides of March.

It must have gotten stuck in the Vegemite. That stuff can even bring an end to Pi.

I thought calculating PI was infinite but our PI day is almost over with just a couple of hours to go.

So far, but they're working on it. 
....In December 2009 Fabrice Bellard used a home-computer to compute 2,699,999,990,000 decimal digits of π. The base-2 calculation, conversion to base 10 and verification took 131 days.....

With a number that big and not totally defined, how can we be absolutely certain of the circumference of a circle?

It's a moving target. Back in the 1950's, a geophysicist by the name of Hans Pettersson tried to estimate how much meteorite material falls to Earth's surface each year. He took nickel samples from Hawaii's Mauna Loa by passing bits of dust through dust filters. Knowing that meteorites contain 2.5 percent nickel, he estimated that 14 million tons of meteoritic material settles upon Earth each year. Then we shoot stuff into space that leaves our gravitational pull causing us to lose some. Heck, who knows. 
If we could just settle down and have a nice piece of PI.  |

We have to cancel the star dust addition by giving back our garbage to maintain balance. Such a deal.
I predict Pi will work out at three billion, one hundred forty one million, five hundred ninety two thousand, six hundred fifty three places. 
Almost makes you think 'finite' is infinite.

If Pi is the relationship between the circumference and the diameter of the same circle, I don't understand how this can be achieved by calculation.
There is a presumption that if the diameter's 7 units, the circumference is exactly 22 units.
This should be a matter of measurement, not number crunching.

There is the mathematical formula so that should you not be able to measure the circumference and only the diameter you can figure out the circumference. None of this is actually used in most people's every day lives. However, they insist on teaching it.

There is a presumption that the formula is correct. Anyone with a cut-out disk and a ruler will tell you that it's pretty close, but when people are running computer programs to work out an approximation to 100,000 decimal places, at what point are they fooling themselves?
