Mathematician makes popular contribution to science Prof Atangana
Prof Atangana is the first African under 40 years of age to be selected as African Academic of Science affiliated in Mathematics. He recently delivered his inaugural lecture and is pictured with Eelco Lukas, Director of the Institute for GroundwaterStudies at the UFS (middle) and Prof Hendri Kroukamp, Acting Vice-Rector: Academic
Prof Abdon Atangana, researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), recently delivered his inaugural lecture on the topic: Understanding God’s Nature with Non-Local Operators.

His research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbation methods, asymptotic methods, iterative methods, and groundwater modelling. Prof Atangana is the founder of the fractional calculus with non-local and non-singular kernels popular in applied mathematics today. He has introduced more than 12 mathematical operators, most of which bear his name (such as the Atangana-Baleanu fractional integral).

He stated: “We will not stop until we change the classical view of doing mathematics. Mathematics is not a subject but a tool given to mankind by God to understand nature. One single mathematical operator cannot portray God’s nature accurately. Therefore the Atangana Baleanu was suggested.”

New weapons

Most physical problems can be expressed in terms of mathematical formulations called differential equations. According to him the differential equation’s aim is to analyse, understand, and predict the future of a physical problem. Prof Atangana introduced the Atangana-Baleanu fractional integral. This brought new weapons into applied mathematics to model complex real-world problems more accurately.

Prof Atangana explained: “The Atangana-Baleanu fractional derivative is able to describe real-world problems with different scales, or problems that change their properties during time and space for instance, the spread of cancer, the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers, and many others. This crossover behaviour is observed in many empirical systems.”

Sudden change

The Atangana-Baleanu fractional derivative is also able to describe physical or biological phenomena, such as a heart attack, the physiological progression from life to death, structural failure in an aeroplane, and many other physical occurrences with sudden change with no steady state.

The new differential and integral operators are nowadays in fashion and are being applied with great success in many fields to model complex natural phenomena. It is believed that the future of modelling complex real-world problems relies on these non-local operators.

The UFS Debate Society will be taking on three major projects during the holidays. The month of December will be filled with activities for the team, with members taking trips to Grahamstown, Pretoria and Berlin, Germany to showcase their debating skills.

Their first project is a coaching session in collaboration with the Free State Schools Debating Board. The team will be coaching the provincial school teams and accompanying them to Grahamstown where they will compete in the National Schools Debating Championships in early December.

At around the same time, members will also attend the Pan African Universities Debating Championships that will be held in Pretoria. The PAN African Championship, which the team won in 2009, has expanded over the years and now also includes participants from Australia and the United States of America.
Towards the end of December, four members of the team will be heading to Berlin, Germany to compete in the World Universities Debating Championships. Ros Limbo, Nkosi Mangali, Richard Chemaly and Zola Valashiya will represent the university.

Zola, who is currently the chairperson of the debating society, has been part of the team since 2008. He describes being part of the teams as, “a growing experience. I have learnt a lot, especially how to be a critical thinker”. He was ranked among the top ten speakers in the English First Language division during the Kgorong 2012 National Universities Debating Championships earlier this year. Zola says the team’s goal is to gain as much experience as possible in order to offer training. They are looking at forming strong relations with various other debate societies across the country.
