What does this mean ¬?

It's not on my keyboard, but I know it's sometimes used in symbolic
logic to represent logical not. So given a proposition P, "Unicycles
are fun." Then ¬P would be, "Unicycles are not fun."

¬ is a 'not' sign
seeing as google ignores the symbol
i used the character map utility

(
click through the following path on Windows operating systems
Start
(All) Programs
Accesories
System Tools
Character Map
)

and found the Alt Code (Alt+0172) the tool tip also told me it was a
'not' symbol at this point, but i was still interested so still googled
http://www.google.co.uk/search?hl=en&q=alt%2B0172&meta=

and this link was the more useful one i followed

I think what you're talking about is the tilde symbol. The tilde symbol
means 'not' in something called propositional logic. Propositional logic
is something that can become fairly complicated, but at it's most basic
levels it is rather easy to understand.

In propositional logic, you have statements that are represented by
single letters. For example, the statement:

"It is sunny outside" can be represented by the letter p. Now, when you
put the tilde infront of the letter p, you are saying that the statement
p is false.

So ~p = "It is _not_ sunny outside" The tilde simply means "the opposite
of the statment".

I hope that I answered your question.

Does this topic warrant one thread in RSU and two in JC? Does someone
really need "help" with this? Look up "research" in the dictionary and
then apply your new knowledge.

symbol

Now two threads in RSU (totally non-unicycle related) and two threads in
JC? These should be in JC at best and one thread at most is required to
cover this "almost" topic. Since they are non-unicycle related, if
another one of these threads pops up in RSU, I will trash all three of
them. If someone knows Andy Parry, please tell him what he's doing.

I'm going to say that it means:

No Question

Absolute fact

0% chance of statement NOT being true

Cannot deviate from statement.

No wiggle room.
