also I read a joke that made me think

here it is:

An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer.

The bartender says "I see where this is going", and pours two beers.

so if 1+0.5+0.25+0.125 goes on to infinity, will it reach 2, the numbers get smaller as we go, hmmmm
