i had one but now that i graduate high school, i need to find something else to do. Lately i have been doing random things... this was one of them. Now im off to find how many numbers are actually in 3.14 (pie)
A better question is how many digits of PI actually matter?
For example, what level of precision is needed to calculate the circumference of the biggest circle you could fit into the (visible) universe, to an accuracy of measurement down to, say, the diameter of a hydrogen atom? And the answer may be smaller than you'd think
he asked how many digits of pi would be needed to get a level of accuracy where the difference between the calculated value and actual value only has an error equal to the diameter of a hydrogen atom
well it was specified that it should be the biggest circle that can exist in the VISIBLE universe, so I don't think the issue of expansion matters in this case.
I figured it like these, please tell me if I am wrong
Radius of an atom = 5.00E-11
Radius of the universe = 1.32E+26
Taking Pi as 3 calculates the size to three value (792E+24) To get to minus eleven we need another thirty five digits, plus the original 3 makes thirty six
If you could find an exact number of registered users and the average number daily guest visits and and the average number of users registering daily, you could do some number work to create some pretty impressive growth figures.
If you guys were ever interested you could use this maybe as one of the many selling points for PA for a grant or something? Not to turn it into a commercial enterprise (I pray you always stay free and open)but to find funding to expand. Maybe buy permissions to port certain apps or other stuff.
Give or take
Stephen, You should move this to the Off-Topic Forum.
Thanks,
Tim
i have gone threw on i have found over 70209 users...
Oh, and you need a life
1,2,3,4,5,6,7,8,9,...
[Edit: as of 9:32 pm Chicago Time]
57,851
Now "I" need a life
Things have got to get better, they can't get worse, or can they?

pi is a non-terminating number, there are an infinite number of digits

That could have kept him busy counting for hours!

wtf. what in the world did you just say? i didnt take chemistry....

know I was just about to work this out, but given that the universe is thought to be expandung, what to I take to be its diameter?
well it was specified that it should be the biggest circle that can exist in the VISIBLE universe, so I don't think the issue of expansion matters in this case.

but is that visible with the naked eye or with the hubble space telescope (for example)?
That would be best answered by Jimbo
The developer formerly known as ZGitRDun8705
that the most distant object ever observerd is in the region of 14 billion light years away, so that would be a good figure to take as a radius.
digits I think

Like I said, not really that many digits, when you think about how many million digits people have spent computer time calculating it to....
trillions. One group used a supercomputer and found out 1.26 trillion digits.
Here, read this (no, I got it from the local library up 206 and down 510

70209?? You're counting is way off. And unnecessary. The number of users is displayed at the bottom of this page: https://portableapps.com/forums
Ed
He didn't count
I'm not sure what method he used but there is in fact a user 70209 !!
I'm thinking that there are numbers that are blocked or retired for various reasons.
The newest user as of earlier this evening was user 77739 [jalanbesi]
Still, he was off by several thousand
But then again, he did say over 70209

Hmmmmm... Interesting
[EDIT]
I Really Wonder Exactly How Many People Are Registered Here
Na na na, come on!
Maybe check all the logins in the world?

As Ed said above, that info is in the footer of the https://portableapps.com/forums page

It would appear that's the number of users who've actually posted to the forums.
