Should we really be relying on proof that is so very old? Seems a bit rash.
Does Pi ever come out if it is worked out in different bases?

I'm deeply wounded. Have you not even seen my other thread about prime numbers in different bases? That must be at least a contender. Just because I care about important things. I suspect that you are merely jealous and possibly a Nazi. Please understand that I am not being rude by calling you a Nazi, just being honest, which as everybody knows isn't rude. Pi is important. Would you rather I just talked about celebrity colonic irrigation or where Michael Jackson has been hiding for the last couple of years???
I am jealous, you're right. Am I a Nazi? Well, I have stepped on a goose.
Pi isn't important, though Michael Jackson in a pie would be excellent. We could all. (B)eat it....... See what I did there?

Sorry Cyclopathic, but this has to be the dullest thread ever on CC.
that's a very bold claim !

ah, but that's the magic of maths - once proved, stays proved !
A bit more tricky these days as there are some things, "conjectures" in the jargon, which are widely believed true, but not actually proven (yet) - then a lot of things have been proved based on this or that conjecture being true. So if one of these conjectures proves untrue, then a swathe of maths will have to be unravelled. More a nuisance than a problem, because each such proof will actually say "assuming Fred Blogg's conjecture, then this then that" so it'll be clear which ones need re-doing.
Sometimes conjectures finally are proven, so all the dependent proofs are then properly true so to speak. And conversely those assuming conjecture is false are not longer valid proofs.
A recent one was the final proving of Poincare's conjecture by a brilliant, but decidedly odd Russian called Perelman. He won a million dollar prize and the fields medal, but didn't bother to collect either. He lives with his mum in a council flat in Moscow apparently.

Mostly unrelated but the volume of a Pizza of radius Z and height A is PiZZa.
Nithing mentioned is a circle. All rough approximations making the value of pi incorrect. No TRUE circle exists in the universe as we know it.

No!! It's feckin brilliant.
The "number" Pi is magical. It's a wonder of the world. It's actually beautiful.
Solve the understanding of Pi and it will answer many many things.

What is meant by a "true" circle. Are you saying my wheels are s**t?

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.
Your wheels are round. They are not true circles. Even before Thom's analysis which is completely true, your wheels are not circles long before the uncertainty principal kicks due to manufacturer tolerance, wear on the wheels, gravity on the wheels etc etc
Boring it may be, but it is correct. The reason I brought it up as that this was about defining a true pi. Now, a wheel, in my guess, would be only as close as as 0.1% away from a true circle (a complete guess but doubt I'm that far off). That's 1/1000. So, pi in this case would be as accurate as that (4 significant figures). 3.141. Wanting pi to be say 3.141593 would far a FAR greater degree of accuracy which your wheels would never be.

It's well known that British Cycling track squad use much rounder wheels than the French. Chris Boardman said so and he's never wrong.
