Maths, but not as you know it…
The third video in the fluid dynamics trilogy I made for Numberphile. Rivers contain 80% of pollution which ends up in the ocean, so understanding where the water goes when it leaves the river mouth is of upmost importance in the fight to clean-up our planet.

There is no doubt that sea ice in the polar regions is melting, but what is the exact role that this plays in the global climate system? To understand climate change we need to understand mixing in the ocean, which is exactly what Andrew Wells at the University of Oxford comes is trying to do by studying a model for sea ice growth in the Arctic.
This video is part of a collaboration between FYFD and the Journal of Fluid Mechanics featuring a series of interviews with researchers from the APS DFD 2017 conference.
Sponsored by FYFD, the Journal of Fluid Mechanics, and the UK Fluids Network. Produced by Tom Crawford and Nicole Sharp with assistance from A.J. Fillo.
Hannah Fry (University College London) talks about her work on the mathematics of data and her favourite problem of modelling the behaviour of people in crowds.
Interview recorded at the Isaac Newton Institute 25th anniversary celebrations.
