In reply to KeithW and ebygomm:

according to Dictionary.com that just refers to any figure-of-eight symbol, not specifically the infinity symbol, for which I'm sure there's a special name...

and
http://en.wikipedia.org/wiki/Lemniscate from which:

In algebraic geometry, the word lemniscate refers to any of several figure-eight or ‡ shaped curves, of which the best known is the Lemniscate of Bernoulli. It is also sometimes used to refer to the ‡ symbol used in mathematics as a symbol for infinity.

In reply to CJD: The opticians I know refer to it as the infinity symbol. The database designers I know refer to is as the infinity symbol. The photographers I know.... oh all right then.

The same name "bolduc" as the greek one meaning "ruban" comes from the Netherlands, the city of 's Hertogenbosh: Bois-le-Duc in french, where was produced this kind of ribbon, used in the sweetshops! un huit couché ...
The lemniscate constant, 1.311028777... results from the square of the GAMMA(1/4) divided by four times the square root of two Pi.
I love the lemniscate curve.

Would that be a countable or non-countable infinity?
