Crafty Mathematics

Mathematical equations can help us get new perspectives, but sometimes can be difficult to understand. This week, one story about how maths has helped the understanding of a enigmatic quirk of heart rate control and another on how crafts can be used to better understand maths.

Mathematical rules and equations can help us get new perspectives on our world, but sometimes can be difficult to comprehend. This week, stories about how maths has helped the understanding of a enigmatic quirk of heart rate control and how crafts can be used to better understand maths.

A new perspective

Alona Ben Tal was sure that her mathematics experiment would be a simple check to confirm an existing idea about heart rate control. When the modelling proved that the existing theory couldn't be true, it instead uncovered new insights into how heart rate is regulated during breathing.

An Associate Professor at the Mathematics Department at Massey University, and a member of the Manaaki Mānawa Centre for Heart Research at Auckland University, Alona uses mathematical modelling to get a new perspective on puzzles about how the heart and lungs work and interact.

Getting crafty about teaching maths

For some it's the scary subject at school but more New Zealanders are rediscovering maths, thanks to a crafty approach by local mathematicians.

Maths Craft uses creative skills such as knitting, crochet and origami to demonstrate the mathematical patterns and concepts that are all around us.
