Did you know that every search you’ve ever run owes something to a self-taught Victorian school teacher?
George Boole was born in 1815, but laid the groundwork for the digital age. He reduced logic to AND, OR and NOT - Boolean logic.
For Information Professionals, Boole is a daily companion. Every database search, every systematic review strategy, every carefully nested set of brackets is Boolean logic at work. Knowing how to combine terms precisely is still what separates a chaotic 10,000 results from the 20 that matter.
For algorithms, he’s even more fundamental. Underneath all the AI and machine learning, it’s still true/false decisions, billions of them per second, running on circuits built on his ideas.
Not a bad legacy for a man who never encountered a computer!

Sometimes it’s the simplest ideas that are most game-changing. And arguably that’s the case with Boolean logic. Here's a very short guide, made in partnership with the Royal Society.
