Reminds me of a mathematician and an engineer in the same class, where

the teacher presents the problem:

Suppose a beautiful woman (or man, take your pick ;-) is opposite a

room from you, and you can approach her/him with the restriction that

each movement can only halve the distance between you and her/him. Will

you ever reach her/him?

The mathematician responds:

No. You may get infinetely close, but you will never reach her/him.

The engineer responds:

You will get close enough for most intents or purposes...

Of course, conceptually, 0.999... does not equal one. It equals

0.999.... But using calculus and other methods you see that 0.999...

approaches 1, and, for all intents and purposes, is equal to 1. It

really depends on what level of precision one is asking for. If one

want infinite precision then one cannot say that 0.999... = 1 unless one

can prove that 0.999... approaches one faster than the needed precision

approaches infinity.

But this is all academic, and is akin to proving that the chicken came

before the eggroll. If anyone wants to prove me wrong, then sit down

and write a 0, a decimal point, an infinite series of nines, and equal

sign, and a one (no shorthand, please!) before hitting reply.
