In this piece Timmy Shum takes us on a journey of mathematical reflecting during Covid.
Ted Chinburg gives an exposition of a basic S-I-R model of epidemics. This model illustrates stability analysis and how the concept of herd immunity arises naturally from differential equations. Some references to more advanced models are included.
Bruce Bassett is head of data science at SKA Africa, professor of Mathematics at the University of Cape Town. He is a senior researcher at the African Institute for Mathematical Sciences and research astronomer at the South African Astronomical Observatory. He will talk about modelling the progression of COVID-19 in South Africa and factors that may influence the spread
Ralph McDougall is a Stellenbosch University second-year Electrical Engineering student who has a keen interest in understanding and solving problems using mathematical techniques. He has developed a tool that provides a visualisation of the number of COVID-19 cases in some countries of interest. The goal was to provide an objective, condensed daily report showing the spread of the virus, which he could use for verification of trends reported in the daily media. He believes that a better understanding of virus modelling will help to reduce the spread of misinformation.
