i usually just see it (on the internet) at the end of a line
that is about to break, meaning that the line shouldnt
really be broken.
like when you see programming examples or something.

it means that something is not something, say if A is a set
and x is an element

"x is in A" means x is an element of A
"x is in ¬A" means x is not an element of A (an element
outside of A)

like the compliment thing, ¬A=A compliment

whee

I see you're in Bath. Nice uni, I've got a lot of friends
down there. You know any of the Architects?

ah damn, i can access those from home thought it's be ok for
others.

mm, it means negation of anything basically if you're
talking infividual things.

so if p can be true or false, ¬p is true when p is false
and vice versa etc.

and ceri, i know no architects. i don't know much about the
department at all. i'm only a first year and quite ignorant
of these things, and bath is great yeah /wickeds/. been
househunting today (how interesting!), fucking hassle, one
house had a load of musicians with synths and stuff
everywhere. my story for today.

I vaugely know one bloke in Bath who has a good analogue
gear collection, PHD Maths student. None of his housemates
play though, so I doubt it's them.

thought i'm late i'd like to say it, too:

the symbol means "NOT".

if you for some reason doubted what other people said, this
can serve as one more proof of the fact that it is really
this way.
