De Morgan's Theorum
Augustus De Morgan was a 19th century mathematician working in the field of propositional logic, he established a series of rules concerned with conversion between different operators using inversion. The fundamental basis of his theory is that NOT ( P AND Q) = (NOT P) OR (NOT Q), and similarly NOT (P OR Q) = (NOT P) AND (NOT Q), this is often known as De Morgan Duality.

In The Beginning... There was 1 and 0
Boolean Algebra is a two state system of algebra, we can apply this to the binary number system where only two valid numeric symbols exist, "1" and "0" and thus use boolean logic to solve binary problems. The electronics inside a computer rely on this system, modeling voltage in a connection as either on (1, or TRUE) or off (0, or FALSE).
