Extrapolation in mathematics means extending the implications of a model beyond the range in which it was derived. In other words, using what we know to make educated guesses about what we don’t. But doesextrapolation works so well when applied to the real world? Can mathematical models really indicate when the next ice age might come? Does genetic testing reliably tell us who our ancestors were? And when we sieve through fragments of history, can we ever escape the assumptions which colour what we will think? Joining Bridget Kendall to explore extrapolation are anthropologist Kim Tallbear who is a member of the Sisseton Wahpeton Oyate from South Dakota in the US; Ian Stewart emeritus professor of Mathematics at Warwick University in the UK and Joan Breton Connelly, classical archaeologist and professor of Classics and Art History at New York University in the US.
