The most efficient explaination of the "
infinity" concept - well, for me anyway.
Mathematical notations with
deltas and
epsilons are alright and much more
useful, but no one got me closer to the "real" meaning of infinity (provided such a thing exists,
of course - see
Intuitionism) than this simple,
informal definition.
Highly recommended for those of you who happen to teach
mathematics to young kids.
