I think I can help Rory with this one. In his recent post, he wonders how is it possible that unlimited Internet access starts at $29.99.

 

Enter the math. I am sure you paid very well attention in high school, so this is just a refresher. There are several kinds of numbers. Some are called natural (to programmers out there - it's like integers), some are called real (again, for programmers - it's like floats, or doubles) and there are others but not interesting for this discussion.

 

There is infinite number of natural numbers, but they are countable (weird concept, I know). There also is infinite number of real numbers, and they are not countable (there is proof, but it's too boring).

 

So in a way, real numbers are more unlimited (more infinite?) than natural numbers :-)

 

I am almost sure that this somehow explains that advertisement.
