Finger Math - The (Brief) History of Chisanbop

Remember the kid in your class who looked like they were playing Mozart on the piano while doing long division? They weren’t. They were a Chisanbop master! This "finger-math" system, invented by Korean mathematician Hang Young Pai, promised to turn your hands into a human abacus. It was the sensation of the 70s, making its way onto national television programs like the 'Phil Donahue Show' and 'The Tonight Show,' where bewildered hosts watched in awe as kids did complex calculations with a series of frantic finger flicks.

Schools across the country, desperate for a new way to engage students with math, jumped on the Chisanbop bandwagon. Classrooms turned into a flurry of finger wiggling and thumb tapping, as teachers believed they were raising a generation of math geniuses. But just as Chisanbop was reaching peak popularity, a tiny, unassuming device entered the picture: the pocket calculator. Suddenly, a $20 gadget could do in a fraction of a second what it took a Chisanbop whiz an entire minute to do, and without the risk of carpal tunnel syndrome. In this episode, we’ll explore the short-lived reign of Chisanbop and ponder the philosophical question: why did we ever think our fingers were better than a Texas Instruments TI-30Xa? Tune in and find out!"
