Toothpaste, Custard and Chocolate: Mathematics Gets Messy

THE 2019 JOINT LONDON MATHEMATICAL SOCIETY ANNUAL LECTURE

This talk looks at mathematical modelling of real, complex fluids in flow situations - some with serious commercial applications, and some just for fun.

Focusing on the chocolate fountain, we experience one of the key day-to-day tools of an applied mathematician, scaling analysis, to answer the question: why doesn't the chocolate fall straight down?

A lecture by Helen Wilson, Professor of Applied Mathematics University College London 29 May 2019
