I came upon this letter when reading a book, I couldn't find its name on the internet, you can imagine how hard it is to search about it.

What is the name of the letter that follows "sample space"?

I know it's not really an English question, but I think this site is best fit for the question than say, the mathematics site.

I'm not quite sure this belongs here. I think math.SE would be able to give a better answer. –  simchona Oct 2 '11 at 16:25

@simchona: probably tex.SE would be better. –  Neil G Oct 2 '11 at 17:56
    
It's also used in the popular Finnish licorice brand, "Sisu" or "Guts": fi.wikipedia.org/wiki/Sisu_%28pastilli%29 Note the lowercase s in the same font--looks like an f. –  user13546 Oct 2 '11 at 20:25
    
And of course a lowercase s at the end of a word looks more like a modern s ... –  GEdgar Oct 2 '11 at 22:16
    
@NeilG Actually, GraphicsDesign.SE does font identifications, providing you check Dextify-like sites first. :) –  muntoo Oct 3 '11 at 4:36

It's an S written in a fraktur font used by mathematicians. This one is easy to find out using Detexify.
