1 does not equal .999999.....The proof submitted: #2 20130409 17:32:56

Re: 1 does not equal .999999.....
Just as long as it is not 8.9999999... That would be intolerable.
I like to think of it like this 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. #4 20130409 20:18:38
Re: 1 does not equal .999999.....Have you fully explored whether m's law of the dots can be safely used after 9 extraction from dots? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #5 20130409 20:23:02

Re: 1 does not equal .999999.....Much better. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #11 20130411 20:33:34
Re: 1 does not equal .999999.....
I would say 99.999... is the number. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #12 20130411 22:26:47
Re: 1 does not equal .999999.....Well I used sound, thoughtout search criteria. I found 9 (or 8.99999... if you prefer) You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #13 20130630 15:23:53

Which search criteria was it?

Re: 1 does not equal .999999.....
a thread which does not come up in that search.

Re: 1 does not equal .999999.....personally, I believe 0.999...=1 in the theoretical word, but 0.999...=0.999... in the real world. why? infinity doesn't exist in the real world, only in theory. thus, an infinite number of 9's is impossible in real life. I mean you cant accurately measure pi can you? nopies! so 0.999... is only a theoretical number. this "infinity exists here but not there" causes the whole topic to be whacko. that's also why the value infinity is kinda whacko. you cant fully explain it can you? nopies.....so really, 0.999... can be thought of along side i, pi, infinity, and all other undefined values that make math involving them impossible to fully explain in exact amounts (like integers, etc.) #18 20130814 11:07:59

Re: 1 does not equal .999999.....
So you think some numbers are only theoretical. So what are the nontheoretical ones? You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #20 20130814 22:48:44

Re: 1 does not equal .999999.....In pratice all measurements and engineering calculations are going to have limited accuracy. Last edited by SteveB (20130817 05:07:27)
