Maths Week Scotland: How Mathematics Uncovered the Dandelion’s Halo

 Sep 30 2021

19:00 - 20:00

Heriot-Watt University and Maths Week Scotland are delighted to welcome Dr Cathal Cummins to explain what mathematics can tell us about natures tiniest fliers.

The equations of fluid mechanics describe how viscous fluids move. When these equations are applied to the flight of the dandelion seed, they give rise to a very peculiar fluid behaviour: a "halo" vortex. So peculiar in fact that such a vortex has never been observed before in nature. So is the halo vortex a quirk of the equations, or is it a quirk of nature?

Dr Cathal Cummins (Heriot-Watt) - whose research focuses on fluid mechanics of swirls, encompassing problems in biology, renewable energy, and beer - will show how equations predict the halo vortex and the implications for the flight of nature's tiniest fliers.
