Ah Yes, Infinity
Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.
Albert Einstein
We must accept finite disappointment, but never lose infinite hope.
Martin Luther King, Jr.
Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.
Blaise Pascal
The infinite! No other question has ever moved so profoundly the spirit of man.
David Searls
There can not be more infinities than one; for one of them would limit the other.
Sir Walter Raleigh
It is difficult beyond description to conceive that space can have no end; but it is more difficult to conceive an end. It is difficult beyond the power of man to conceive an eternal duration of what we call time; but it is more impossible to conceive when there shall be no time.
Thomas Paine
To see a World in a grain of sand, And a Heaven in a wild flower, Hold Infinity in the palm of your hand, And Eternity in an hour

Re: Ah Yes, Infinity
Definition:-
log (x) is denoted as log(1)x
log (log x) is denoted as log(2) x
log[log(logx)] is denoted as log(3)x
and so on.
We know that log of zero or a negative number is not defined.
My question is, for what value of n would log(n) ∞ i.e. log(n)infinity, be not defined?
(eg. log(6)Googolplex is not defined.)
Warning : We are moving from infinite to transfinite

Re: Ah Yes, Infinity
It is impssible for the human mind... Nah- nah-nah-na-na-naaaaaaahhhh. Sorry. That song was on the radio whilst I was typing this.
Where was I? Ah yes.... to comtemplate infinity. Try thinking about a limitless about of anything. It is impossible, something always creeps in, without you noticing. The human mind is too advanced and yet, retarded. It's advanced in the way that we have words that we know what they mean, but cannot visulaise them. (That's the retarded bit)
Anyway, this last week I've been all on my own at work and...............the building is still standing and has been re-posessed. I'm so proud of my self *sniff*

You got through the week without causing any major damage, embarrassment or financial loss????
Well done!

So, you are asking about taking an infinite series of logs, starting with n, and hoping that you do or don't go ≤0 ... ??
Lets test it at n=2: log(2) = 0.301, log(0.301) = -0.521, log(-0.521) = undefined
So, for n=2 we did log three times and got an undefined
Lets test it at n=20: log(20) = 1.301, log(1.301) = 0.114, log(0.114) = -0.942, log(-0.942) = undefined
So, for n=20 we did log fourtimes and got an undefined
(BTW I used log10)
Is that the idea?

Re: Ah Yes, Infinity
I think that's it, because ganesh's log(6)googolplex fits that.
log(0)googolplex=googolplex
log(1)googolplex=googol
log(2)googolplex=100
log(3)googolplex=2
log(4)googolplex=0.301...
log(5)googolplex=-0.521...
log(6)googolplex=undefined.
And none of that needed a calculator!
Why did the vector cross the road?
It wanted to be normal.

Re: Ah Yes, Infinity
Yes, I used logarithm to the base 10 for convenience.
The idea is to show that
Infinity + 1 = Infinity
Infinity + Infinity = Infinity
Infinity x Infinity = Infinity
Infinity ^ Infinity = Infinity
Infinity ^ Infinity ^ Infinity ^ Infinity ........Infinite times = Infinity
This is true because because we can never say for what value of n
log(n)infinity would be undefined.
And this is only the fourth stage of iteration (also referred to as 'tetration').
No wonder, Infinity is beyond comprehension for the human mind!
