0.99 isn't 0.9r though is it?

Too many people don't know maths? Look at AcidHell, he things 1 is bigger than infinity ;)

I see that someone's already responded to your second paragraph. It's your first paragraph that has me puzzled.

If you're suggesting that people should not read past the third page of this thread, how are they going to read your post to receive, and follow, this advice?:D

I don't expect to receive a reply from you, as I'm sure you'll be following you own advice and therefore won't be reading my question.
 
PROOF THAT 0.9r = 1

;)

That aside, I voted that it does.

Mathematically 0.9r does = 1, there is no question about this, and I would love to see anyone try and prove that it doesn't.

Logically most people fail to comprehend what recurring means, infinite is not and never will be finite.

On the other hand though I can understand that some class recurring as a limitation is of our mathematical model (I am not talking about most peoples' posts here that go on about random rubbish), and that 0.9r is merely an infinately long approximation to 1.

My biggest reason for 100% believing that 0.9r=1 is that 0.9r does not exist outside of mathematical models, so if the maths behind 0.9r PROVES it equals 1, then it does in deed =1.


Also a lot of respect has to go to alphanumeric, he's taking a lot of undue bashing here when all he is doing is stating logical concrete facts that any a-level or above mathematician should know.

Ah. I'm studying for my maths A level now, and I know it, so I assumed everybody would ;)

And tbh it's basic common sense surely? Ask anyone on the street how the hell 0.99 could become 1 without rounding up and they're going to say it cant be.

'People on the street' aren't exactly bastions of mathematical genius now are they?

Because apparently it's not a mathematical issue, it's a "philosophical" one. Although I'll leave that one to the philosopers (as they say), I'm talking in a purely mathematical sense.
 
Hmm within a few posts I already regret even getting involved....

Forgot Maths people aren't too keen on people intruding on others turf ;) Should have realised that by page 3 tbh.

One final point, if 0.99r does equal 1 which some of you seem very keen to believe, why's it not called 1 instead?

6that where you cant grasp the natur of inifinty.

.9r is infinity and less than 1 all at the same time, try expanding your mind with pholosophy(spelling), rather than just science and maths ect..
infinity simply means never ending.

anyway i will leave saying

in maths 0.9r = 1 as maths is flawed
in the real world which i can live in and touch 0.9r < 1

anyway im off now.

Touch infinity?

In Maths 0.9r IS 1.

I may of been posting, begging to driffer, trying to disprove. However, I voted yes, I just enjoy questioning things.

Given 1, and 0.9r are maths entities, its for maths to talk about. Do you accept 2<1? 3<1?, 10<1? 10000000000 < 1? How about a really big number? 45873968629086358236908326098326098364509832650938265 < 1?

Keeping going and suddenly it goes to less than 1? Sure it does ;)

No, 0.9r has an infinite decimal expansion, not the same. Between 0 and 1, there are uncountably many numbers with an infinite decimal expansion (just think of rational multiples of pi), yet are between 0 and 1. How can they be infinite?

If you're going to argue something, at least get your words right (for the second time) ;)

Here's 2 questions...

Does something that is infintely small exist? If so define it somehow.


Also "if" time is infinite (or going around a circle until you reach the end), is there a beginning or end of time?

Im thinking that was a sarcastic thing and a joke. However, with what has been thrown around in this thread, im left to wonder?

Better safe than sorry.
 
I am strongly technically minded person/

Can somebody tell me whether 0.9r is excatly 1 only at the limit.

If the number of 9s after the decimal place is stopped b4 infinity then it is surely less than 1. Well after a billion dps it might as well be 1. BUT Thats rounding off and it cant equal EXACTLY 1..


I voted yes btw.

I'm happy to discuss maths, hence why I post in other maths threads to help people. Its just its slightly offence when someone comes along and just with a sweeping comment goes "Nope, all 2000 years of maths is wrong", with nothing to back them up but their opinion and such bad logic it resembles swiss cheese.

From a physical perspective. You can probably take planck Length as being smallest possible amount. 10^-33m IIRC

They use this amount in string theory. Anybody with experience with this sort of physics can help hopefully.
