and 1-0.9=0.1

It is with this sort of lazy botched math (0.9=1) that you arrive at scientist breaking the speed of light with neutrinos. The speed of light! The fasted speed we could come up with!

It is a very good example of why taking short cuts like this 0.999=1 will re-write the rules of the universe as we know and put it at risk of imploding!


This has got to be about one of the worst attempts of doing any sort of math proofs I've seen. Not to mention that it seems to have nothing to do with what we're talking about. We're discussing 1=0.(9) and not 1=0.9. To be more specific that is 1=9/9 as opposed to 1=9/10.

.999 != 1 



What he doesn't seem to realize is that a decimal is not an exact answer (well as far as answers from computers are concerned) and so basically what he is saying is that the approximate solution is exact and that the absolute true representation of the solution is wrong.

There is no more of a way to be more exact than use rational numbers. Converting to decimals (even if it can be expressed in continual repeating digits) is considered to be approximate in most cases.

Or more simply faulty logic is faulty.

This, I find interesting. I would like to see some evidence that (1) neanderthals didn't use math, and (2) everything that came after neanderthals did use math daily.

Here's a brief history of counting. I was fairly accurate, it seems :D

See, I just thought that the point of the "he says on the internet" comment was that the internet (as an extension of computers) is basically nothing but math underneith.

Actually that was the original intent, but either Z_B missed it or decided to ignore it :P I'm guessing it's the last.

So basically, we have a bunch of people coming with proof that they're the same, and a bunch of people saying (or screaming) that they're not without proof. Interesting.

Also to the people saying that 1 is only ever 1 and no other number can be 1, I would like to say 2/2.

Here's another one, to see if people really just don't get the concept of infinity or are shouting for the heck of it.

Of which are there more? Positive whole numbers, or Positive + Negative whole numbers?



2/2 is another way of writing 1 broski.

Yeah, and so is 0.999(9)

Different ways to write the same value.
