I find that quite amusing to be honest, having been involved in this thread i have asked several people outside of the forum the same question
3 of which are
A Engineer
A 25 Year Chemistry Industry manager
A Chemistry and Biomedical Sciences Degree Student
Not exactly Thickies.
and all of them said that 0.9r was not 1 all said theres always going to be that little bit left over that you need to turn 0.9r into 1.
Now the thing that I find amusing is even after I showed them the proof they still wouldnt believe that 0.99r = 1.
Now the thing i find quite amusing is, in most other intense threads on here, it gets to the stage where proof doesnt matter one person has there view another has another and eventually both views are just accpeted. Which in this case really should be the case.
However in this single thread from both sides I have seen the most unmoving and sometimes downright I know it all I'm better than you comments much like the one I have quoted.
Now at the end of the day, it doesnt really matter, it aint going to change anyones life whether you convince them or dont, it will be forgotten by the end of the week. So theres just no need to get so serious about it, those who believe it does, put yer point across to the nth degree if needs be to try and convince people, but at the end of the day comments like the above are simply not needed.
Surely the maths people can understand that to a none mathmatcian this question would 99.9% of the time gain the instant knee jerk NO it isnt reaction ? and the reasons why ?

My maths teacher wouldnt believe the proof, he says its all nonsense!
ha, he is 50+

True. Its not exactly "common sense" and people like to stick with their common sense. It just takes a while for you to learn that somethings you have to think differently (as people in this thread keep telling me and other maths people to do, yet we are thinking without the bounds of reality after all
).While I understand Memphisto's friends not beleiving, its not their areas of "experience", but a maths teacher? Lets just say your maths teacher would have hated to have me as a student!

I want to know, what applications (and if you don't use that word in this context in English, what use) can you make out of the knowledge that 1=0.9r ? What can you work out that was previously impossible/much more difficult?
Soldato
It lets you integrate and differentiate.

"Applications" is the wrong word. Its okay to say "What applications is electomagnetism used for", its an entire field of physics, its not the fact 0.9r = 1 gives us a new "field of thought", its the fact it just is true.
As Rich_L says, that result and a bunch of others, while individually seem perhaps a little pointless to a layperson (no offence), combined become some of the most powerful applications in maths (and in physics).

Which is?

A Level stuff, and pretty much the basic language of every single bit of Applied Maths ever. Derivatives describe smoothly changing systems, as you find in physics. The amount of maths you can do just to investigate the properties of Diffrential Equations could keep you busy (and for some people, does) for the rest of your days.

Banach Space (exact quotes):
Haly: It's a Complete vector space... can't remember much more
Mathworld: It's a complete Vector space...(goes into notation she wont understand)
Vector Space:
Haly: It's a space where you can add and multiply vectors
Mathworld: Is a space which is [closed under] vector addition and scalar multiplication.....(goes on) (and btw, you cant 'multiply a vector (A-Level/GCSE knowledge)
Does seem to link up strikingly
If my calculations are correct, but the time I hit 3rd year (are you 3rd year Alpha?), I will have done around 1500 hours of maths between GCSE and 3rd year degree. If you can pick up that kind of knowledge from a few converstions on maths from a lecturer - then WOW!
Also, Alpha - how on earth do you prove 1>0 from the axioms! (i'm totally lost!)
Soldato
Sure you don't mean 1499.9r?
If you asked a new born baby if 2+2=4, half would randomly hit the yes button, half would randomly hit the no button. I can understand why people are getting it wrong.
I wouldn't say I was a know it all, but believe me 0.99 recurring is 1. The babies eventually learn that 2+2=4, and hopefully everyone in this thread will learn that 0.99r is 1. That was the point of my first post, maths is based on concepts we think we all understand - intuitively if you like. We try and make these concepts as few as possible, but you cannot absolutely prove the axioms of maths.
Now if a random came up to you and said 2+2 is not 4, you would say exactly what I said, a knee-jerk reaction that 2+2 is 4, and so would the vast majority of the population.
I think it does matter, the fact that surely in the 30 pages there must be at least one decent explanation for why 0.999r is 1 yet 250 people still vote against and go away not having learnt a thing.
