Toothpaste, Custard and Chocolate: Mathematics Gets Messy

THE 2019 JOINT LONDON MATHEMATICAL SOCIETY ANNUAL LECTUREUploaded 10-06-26This 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 2019The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/mathematics-gets-messyGresham College has been giving free public lectures since 1597.
