Since you don't know enough not to force a totally unrelated post onto someone else's thread, I guess it should not be a surprise that you also know no mathematics > [1 paradox] Why 0.999... is not equal to 1? > > Written in 2012 > > The current mathematic theory tells us, 1>0.9, > 1>0.99, 1>0.999, ..., but at last it says 1=0.999..., > a negation of itself (Proof 0.999... =1: > 1/9=0.111..., 1/9x9=1, 0.111...x9=0.999..., so > 1=0.999...). I have no idea what your "proof" is even saying but it should not purport to be a proof that 0.9999...= 1. That can be done very nicely by noting that 0.9(1+ .1+ .01+ ...)= 0.9((.1)^0+ (.1)^1+ (.1)^2+ ...) is a "geometric sequence" and anyone who has taken an "intermediate algebra" or "precalculus" class should know that the general geometric series, a(1+ r+ r^2+ ...) has sum a/(1 r). With a= .9 and r= .1, that is .9/(1 .1)= .9/.9= 1.

God is in all of the world, not just the "infinite world" whatever you mean by that.
We deal with "infinite" things, sequence, series, all the time in mathematics. The fact that YOU have never taken a real mathematics course, don't change that. > > 0.999... is a number in the infinite world, but 1 is > a number in the finite world.

Apparently you have never taken a Calculus course.

Which is WHAT? Something you just made up? > > Because of the indeterminate principle, 1/9 is not > equal to 0.111.... > Since you don't tell us what the "indeterminate principle" is, this is again nonsense.

You are comparing "apples and oranges". MATHEMATICALLY we can talk about "1/9" of something. PHYSICALLY, you cannot have exactly "1/9". And once you mention "measure tools", you are talking about Physics, not Mathematics

So essentially what you are telling us here is that you do not know what mathematics, physics, or philosophy ARE! > > More info, three other download points(written in > Chinese): > (1)www.speedyshare.com/DQz9y/AiforSC.rar > (2)localhostr.com/download/3LtuSLb/the%20end%20of%20th > e%20world.rar > (3)bayfiles.com/file/F5tD/B8M4Xh/AiforSC.rar
