Achiral fans

[pozorvlak]

It's a little-appreciated fact that fans are chiral (ie, they come in left-handed and right-handed versions). Don't believe me? Lend your favourite fan to a friend, and watch them try to open it the wrong way, messing up the spokes. This has two downsides: first, the fact that your friends will infallibly open your fans the wrong way and damage

I read "fans" in the first sentence as "people" (e.g. science fiction fans), so when you said "some are left handed and some are right handed" I thought "Well, yes, obviously". Things then got a bit weird when you talked about lending them to your friends :)

Yeah, that was deliberate, hence only putting the clarification in the second paragraph :-)

And here I was wondering why on earth you'd want to lend out your case fans; and what this would have the recipient do...

And then ... at least I didn't immediately associate to Gröbner fans y'know... But ... wait ... if you want to do Gröbner walks between different noncommutative Gröbner bases, you may end up looking at the (possibly) different fans you'd have to traverse for a right resp. left basis... :P

Heheh :-)
