Internet search giant Google on Monday dedicated a doodle to noted mathematician George Boole, whose legacy of Boolean logic is credited with laying the foundations for the information age, on his 200th birth anniversary.
An English mathematician, Boole worked in the fields of differential equations and algebraic logic, and is best known as the author of the Laws of Thought which contains Boolean algebra.
"His legacy surrounds us everywhere, in the computers, information storage and retrieval, electronic circuits and controls that support life, learning and communications in the 21st century," says GeorgeBoole.com, a University College Cork website dedicated to him.
He also devised a type of linguistic algebra, now known as Boolean algebra, the three most basic operations of which are "and", "or" and "not", reports the Sydney Morning Herald.
Born 200 years ago on November 2, his algebraic approach to logic, in which all values are reduced to either "true" or "false", is still used today.

Boole died of pneumonia in 1864, when he was 49 years old, after he walked two miles through cold rain and then lectured wearing his wet clothes, reported.
Today's special doodle is visible on a majority of Google's homepages across the world.
