George Boole Jnr (/ buːl /; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland.

The operator for the conjunction operation is AND or this symbol: ∧. The conjunction combines two boolean expressions: As xx and yycan only either be 0 or 1 all possible combinations can be written down in a so called truth table: All combinations of xx and yy are listed in the first two columns of the truth table. In the last column is the result ...
The next operation is the disjunction with its operator OR and the symbol: ∨. In the same way as the conjunction the disjunction combines two expressions: However, the operation evaluates to 1 when atleast one of the variables is 1: The only way to get the disjunction to result in 0 is when both expressions xx and yy are 0. The OR operator in Pytho...
The last operation of the Boolean algebra is the negation and the NOT operator and its symbol: ¬. The negation only takes one operator: When using the NOT operator 0 turns into 1 and 1 turns into 0: In Python the negation is represented by the notoperator, which you can use like this:
You can form any logic expression by only using the three operators AND, OR, and NOT. For example, an often-used operator is the exclusive OR (also called disambiguation). XOR takes two boolean expressions: and evaluates to 1 if and only if xx and yyare different. The truth table for XOR looks like this: And it can be constructed in different ways ...
Introduction. English Mathematician. Inventor of Boolean Algebra. Two major writings that incorporate George Boole’s work: “The Mathematical Analysis of Logic”(1847) and “The Laws of Thought” (1854) Known as the "founder of the field of computer science" Major influence on development of computer circuits.

Nov 2, 2015 · Who Was George Boole? But let’s talk about George Boole, the person. Who was he, and how did he come to do what he did? George Boole was born (needless to say) in 1815, in England, in the fairly small town of Lincoln, about 120 miles north of London.
