About this episode

The episode discusses how ancient dice used by Native American hunter-gatherers influenced trade and mathematical concepts.

An ancient collection of dice discovered by archaeologists might rewrite the history of how humans have understood mathematical concepts like probability. A new Colorado State University study examined the earliest known dice in human history. Native American hunter-gatherers across the western U.S. first used the dice as early as 12,000 years ago. Robert Madden , the CSU researcher behind the finding, says these dice weren't just for entertainment. They were tools of commerce. They helped people barter and trade goods – and also helped shape early thinking about probability and other math concepts. Robert spoke with Erin O’Toole about the discovery and what it reveals about humanity’s long-running fascination with games of chance. * * * * * Sign up for the In The NoCo newsletter: Visit KUNC.org Questions?
