So what exactly is fuzzy logic? Is it just a funny phrase? Nope...it's an actualy theory...in
fact, it includes math! Observe the table to the right: here are some dictionary definitions and a brief history on fuzzy

"Fuzzy logic is a generalization of standard logic, in which a concept can possess a degree of truth anywhere between
0.0 and 1.0. Standard logic applies only to concepts that are completely true (having degree of truth 1.0) or completely false
(having degree of truth 0.0). Fuzzy logic is supposed to be used for reasoning about inherently vague concepts, such as 'tallness.'
For example, we might say that 'President Clinton is tall,' with degree of truth of 0.9."
