Description It is a well known fact in mathematics that the harmonic series - the sum of reciprocals of natural numbers - is divergent. Read more about it on Wikipedia: [link]

In Slovak:

To, že harmonický rad - súčet prevrátených hodnôt prirodzených čísel - diverguje, je v matematike dobre známym faktom. Prečítajte si o tom viac na Wikipédii: [link] (po anglicky)

As a mathematics undergraduate, I wholly approve of this animation But your deviantID tells me you're more for physics than maths, isn't that right?

Thanks.
Yes, that's right. As a physicist I need to know a lot of math as well though.

The program that I used for animating is Synfig.

Nice. Didn't know about it before (or at least never really realized this). Math can be an art in itself.

Beautiful! It actually makes sense to me, now!

That was great. I knew it was true, but the proof we were told wasn't quite a clean as this one.

If n=1, then the sum is 1
If n=2, then the sum is 3/2
If n=8, then the sum is somewhere between 2 & 3
If n=974698745, then the sum is significantly less than n
If n=infinity, then the sum is infinity, yet it is still significantly less than n.
Therefore infinity > infinity... wait... what? xD

Infinity is a relative term, and impossible to define.

Nice animation by the way. Very clear.

Thank you.
Yes, infinity is an interesting concept, and there is more than one kind of infinity.

On the other hand 1 - 1/2 + 1/3 - 1/4 etc is ln(2).
