Emanuela or Someone Else,
Please take me back to basic math since it's been such a long time and I've forgotten too many names of numbers:
1. The number ten divided by 7 equals 1.42857142857142857142857...ad infinitum
2. So that number (1.42857142857142857142857...ad infinitum) is an infinite number and has something to do with our concept of infinity, right?
3. And if you were to consider your index finger exactly (if it were possible) 1 inch away from you thumb and you were instructed to move it to the precise position of 1.42857142857142857142857...ad infinitum (or 10 divided by 7), well, you wouldn't be able to do it because of the nature of infinity. You would only be able to move by consistently changing position as the numbers behind the decimal points continued--and you'd never catch up because of the nature of infinity.
4. Now the question I really want answered: If we agree (those who are on this wagon) that .9999999... equals "1", what does 1.42857142857142857142857... equal? Do we stop at the point at where the sequence begins to repeat, say 1.428571... and that is ample?
And, more importantly, what do we call such a number--a number that is actually infinite, but one we agree to set limits upon?
