The Game of life

“Philosophy is written in this grand book --
I mean the universe --
Which stands continually open to our gaze.
But it cannot be understood
Unless one first learns to comprehend the language
And interpret the characters in which it is written.
It is written in the language of mathematics,
And its characters are triangles, circles, and other geometric figures,
Without which it is humanly impossible to understand a single word of it.”
Galileo Galilei, Il Saggiatore (1623)

Hi Ubergeek;
Thanks for the link.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: The Game of life
In regards to the second link, that actually works anytime you use .999....
for example:
N = 2.99...
(multiply both sides by 10)
10N = 29.99...
(subtract N from both sides)
9N = 27
(divide both sides by 9)
N = 3 = 2.99...
or
N = 0.7999...
(multiply both sides by 10)
10N = 7.999...
(subtract N from both sides)
9N = 7.2
(divide both sides by 9)
N = 0.8 = 0.7999...

Re: The Game of life
help disproving 1=0.999....
ok, so this has been driving me nuts since I first saw it on the site. I understand that the mathmatical difference between 1 and 0.999.... is so minute as to make them practically the same thing, but they are not exactly the same. I can see the math is screwed up . . . well, it's more that I feel it, but I can't seem to disprove this yet. can anyone help?

Hi thoughtdotcom;

First start here, they are not practically the same thing they are the same thing.
I can see the math is screwed up
The math is fine, you are using human common sense when you feel it is incorrect. Unfortunately lots of math is counterintuitive and sometimes seems to be wrong. That is an illusion.
but I can't seem to disprove this yet. can anyone help
Please, try to understand the proofs that you have seen.

Re: The Game of life
Thank you bobbym for replying. I was all set to leave this alone after your post, but a co-worker (we'll call him: Mr. Coffee) got himself involved. He believes that there is a problem in the step where we subtract x from each side of the equation. The way he puts it is: when you do something to one side of the equation, then you must do it to the other. So when we substitute 0.99... in for x on the right side of the equation, we must also substitute 0.99... for x on the other side of the equation. this gives us:
x = 0.99...
10x = 9.99...
10x - x = 9.99... - x
10(0.99...) - 0.99... = 9.99... - 0.99...
9 = 9
could someone look at this and tell me if it's correct, please. I'm anxious to know if Mr. Coffee has hit upon something, or not.
thanks.
I think, therefore you are.

Re: The Game of life
Hi thoughtdotcom;
Mr coffee hasn't done anything deep. This is how someone who's training is mostly discrete and numerical looks at it. Someone who can't discern the difference between rigor and rigor mortis.
1 = .9999999999999...
10 = 9.99999999999...
Subtract the top equation from the bottom:
9 = 9
Er spielt so einfach!
That convinced me a long time ago. Convince yourself now.
