### Re: A very interesting Mathematical Paradox

This part is, I think, what bugs me so much. If an infinitesimal is defined as \frac{1}{n} where n=infinity, then you're arguing that there's a case where \frac{1}{n}=0 . I can't reconcile this. In fact it is quite easy to reconcile. If an infinitesimal is defined as you describe, it is not a real ...

### Re: A very interesting Mathematical Paradox

Two things, and I'll drop this: Why is the definition of the sum of a convergent series defined to be the limit? Simply saying "Because it is" isn't going to fly. You know how to add two numbers together. By induction, you know how to add any finite number of numbers. But the grade-school ...

### Re: A very interesting Mathematical Paradox

All real infinitesimals are zero. Lies. I refuse to believe that an inherently nonzero, albeit ridiculously small, number equals zero. Perhaps I'm unclear. I don't want to hear some recycled "argument" which relies on "previously established" rules, because these rules presuppos...

### Re: A very interesting Mathematical Paradox

You have now had a chance to think about the Archimedean property. It still says that for any positive real number r, there is a positive integer n such that 0<\frac{1}{n}<r . Next, AWA, are you familiar with the trichotomy property of real numbers? It states that for any real number x, that number...

### Re: A very interesting Mathematical Paradox

But, I'm intending to construct the repeating decimal. I'm just stopping along the way. If we can suppose that We're trying to reach (0.4368,0), then we can construct that by first plotting (0.4,0), then (0.43,0), then (0.436,0), and finally (0.4368,0).

I didn't read the entire thread, so I don't know if this was addressed already, but my main beef with the whole 0.999... = 1 thing is this: If one were to plot the point (1,0) on a graph, one would expect that it would be identical to the point ((0.999...),0). However: If you construct the point tha...

### Re: Pipe-organ music!

Not exactly "more epic" than TaFiDm, but the Little Fugue in G minor is, I think, one of the more fun songs to listen to, as well as play.

### Re: Fugues

I was about to suggest Bach's Toccata and Fugue in D minor (BWV 565), until I saw Eitel suggest it in the last post on the page (some kind of psychic-ninja).

Anyway, a fun fugue to learn would be Bach's Little Fugue in G minor (BWV 578). I find it rather fun to both play and listen to.
