Do you think Hamilton and Scherzinger will ever get married? ;)

But seeing how infinity is an infinite value, one would assume that dividing by infinity would have to be so insignificant that you get zero.

Eventually you have to call it quits, no?

msater: Can I ask one more question?

Vader: You just did anyway. Why ask?




SchueyFan: Do you think Hamilton and Scherzinger will ever get married? ;)

Vader: If you ask for my personal opinion on this I'd have to say that I don't really care enough to waste time thinking about it.




smorr: But seeing how infinity is an infinite value, one would assume that dividing by infinity would have to be so insignificant that you get zero.

Vader: If there is a difference between 0.0000000001 and 0.00000000001 (and no rocket scientist would deny that fact) it is clear that there also is a difference between infinitely close to zero and zero as such, as insignificant you may think it is.

Eventually I don't call it quits, I call it logic.

but if 0,99999999999999... is the same as 1, then surely 1/infinity is the same as zero. right?

Vader: No, it definitely isn't. 0.99999999999999999 is 0.99999999999999999 and 1 is 1. Almost pregant isn't pregnant either.

But we are talking MANY more zeroes before a one, as in a INFINITE amount. The result is so close to zero that there is your result.

Vader, do you have a math major?

Vader: Extremely close to zero is not zero. If so there were no different terms for "close to zero" and "zero".

smorr: Vader, do you have a math major?

Vader: I have a degree in English and philosophy. Remember, the first greek mathematicians regarded themselves as philosophers. My definition of philosophy also is classic. I don't go for that postmodern gibberish. Never forget: formal logic - as mathematical as it looks - is a classic discipline of philosophy.

Whats your opinion about Voltaire and Rousseau?

Frantic: Whats your opinion about Voltaire and Rousseau?

Vader: Both honorable men and famous philosophers. As a firm believer in the principles of Enlightment I have a very high opinion on Voltaire. I do not necessarily share Rosseau's optimism concerning the good nature of men, but he certainly has his deserved place in history.

So even if you have .01^Infinity, you still have 1. Which, means you must know where exactly infinity is. Who is to say that everything we know about math stays the same when counting infinity, after all, it's not really a number.

And even if there was a negligible difference between 0 and .01^Infinity the difference would be SO small that even for intergalactic equations it still wouldn't matter. Even on the biggest scale possible you still think it really is different in a practical sense?

Vader: If it's not a number there is no wonder why dividing by it is so hard. But yes, it's a limit and by difinition limits can be approached but never fully reached.

smorr: And even if there was a negligible difference between 0 and .01^Infinity the difference would be SO small that even for intergalactic equations it still wouldn't matter. Even on the biggest scale possible you still think it really is different in a practical sense?

Vader: If the difference didn't matter it simply wouldn't be there.

Is it really different in a practical sense? No, you are right - it isn't.
Is it really different in a technical sense? Yes, I'm right - it is.

So what? Maybe in a few hundered years people will find out it matters. Who knows? And even if not it is important to mind that technically there is a difference. Why? Because of the same reasons that make people find new places after the decimal point for pi. Here you could also argue that it doesn't matter when obviously it does.

In science, if you want little bangs, do chemistry. If you want the really big bangs, do physics. ;-)

Calculations matter in physics. If you're out by 0.1 x 10^1000, it's still out. No amount of rounding will compensate for that in the real world.



Everyone knows that million-to-one chances happen 9 times out of 10; indeed, it's a common requirement in fairy tales. If the human didn't have to overcome huge odds, what would be the point? Terry Pratchett - The Science Of Discworld

Vader: So where's your question? It's the "Ask Vader" and not the "Discuss Things" thread. OT posts will get deleted. Why? Because I say so and I can.

I had the question, but it seems to have got lost between typing and posting. Forum error?

ok. let's call the fraction that generates 0,999999... "x".

x=0,9999...
10x=9,999...
10x-x=9,999...-0,999...
9x=9
x=1

therefore, 0,9999...=1

right?

Vader: I deleted he post anyway since it wasn't a question.

Vader: Because we're all nerds.
