Re: The Game of lifeHi Ubergeek; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20090729 05:56:13

Re: The Game of lifeIn regards to the second link, that actually works anytime you use .999.... Last edited by thoughtdotcom (20100125 07:53:35) I think, therefore you are. #7 20100206 03:43:18

Re: The Game of lifeHi thoughtdotcom;
First start here, they are not practically the same thing they are the same thing.
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.
Please, try to understand the proofs that you have seen. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20100208 04:17:25
Re: The Game of lifeThank you bobbym for replying. I was all set to leave this alone after your post, but a coworker (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: I think, therefore you are. #10 20100208 12:25:52
