< AreThree> mmm, open-faced club sand wedge
< mugu> what makes it open faced?
<@PetrDoubt> Not being closed.
< mugu> how does one close a sandwich?
< teferi> mugu: one takes the union of the sandwich and all its limit points, of course

Yes, yes you are.

I'll spare you the jokes that ensure I'm going to chem nerd hell.

Haha, but the set of all sandwiches is finite, so each one is open and closed, no? Unless, I suppose, you were going to get into sandwiches that might have been made but weren't, or sandwiches that are going to be made, in which case you'd end up considering far more questions than one normally does in making an open(andclosed)face sandwich.

and no, i don't know you, but i was curious as to who else would list 'vector spaces' as an interest.
