At last!

The concept of convergence is interesting in this: depending on the

domain of application, it can mean different things.Two lines that converge 

will meet, two series of numbers will not. They approach a certain limit, at 

infinity. If I were a physicist, this would be of concern to me.

So we can cut off pi at 3.1415 and proceed with cutting tiles for

the kitchen. This does not mean there are zeroes past this point; it is

an arbitrary cut-off!
