Does Pi ever come out if it is worked out in different bases?

Now you are taking the p1sh. Everyone knows he's camping out round Elvis' gaff.

This explains that pi is an irrational number. It strikes me as highly irresponsible of us to be using an irrational number to work out all of our circles. Who knows what it will do next? I am very worried by this and hope that the scientists manage to rationalise pi very, very soon.

But according to the link - an irrational number is one that cannot be explained as p/q where both are integers; the 3.14285714... Originates from 22/7 doesn’t it? And both 22 and 7 are integers aren't they .

22/7 is not pi. Accuracy to about 3 significant figures

Thanks

...and if you want a better approximation than 22/7 then 355/113 is for you. Does 6 or 7 significant figures I think. More than you are likely to need anyway.

This is the point. If you are measuring a wheel, the best you could do is 0.1mm with a ruler/tape measure. That would be to 4 significant figures. Having pi to 20 would be pointless as the error in measuring would outwiegh the error in pi.

In fact for many practical purposes, 3 will do. There's an urban myth that some US state or other passed a law decreeing pi to be 3. I just looked it up, and found that it has a rather strange basis in fact. See here: http://www.straightdope.com/columns...egislature-once-pass-a-law-saying-pi-equals-3

The secret of a perfect pie is how to avoid getting a soggy base.
I don't know.

Blind bake the base with some uncooked rice in the bottom of it.

Its a tedious observation that any physical manifestation of a shape through an object is built with atoms that, since they are discrete in themselves and quantum in nature, have unknown position/momentum with ether in between, hence are impossible to configure in any perfect shape even if they have crystallised into regular enough patterns on a microscopic scale. That is even before we might consider gravity's deformation of space time…
The observation while trues is rather pointless in my opinion.

It's probably the uncircularity of my wheels that is the reason for my poor average speed of about 12mph. Thanks for clearing that up, I thought I was just unfit.

That and as with circles, distance is difficult to measure due to quantum uncertainties, time not being constant (both required for speed calculation)... but yes, being unfit probably more significant!

Bullcrap, it is now obvious to me and any one who cares to really get to the bottom of things in actual reality (not that virtual stuff they have nowadays) that my poor performance on the bike is entirely down to none round round things. And quantum. Obviously.

 

[Markymark]

Obviously.
