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 Academy of Science of South Africa (ASSAf) has elected former Vice-Chancellor and Rector of the University of the Free State (UFS), Prof Jonathan Jansen, as its new President for the next four years. He succeeds Prof Daya Reddy. Distinguished Professors Brenda Wingfield and Barney Pityana were elected ASSAf’s new Vice-Presidents.

The minds that shape tomorrow
The academy’s directive is to advise and provide the government with evidence-based solutions to national problems; inspiration, and examples of how science and technology can be applied for the benefit of society. ASSAf represents scientists in South Africa but also represents the country in the international community of science academies.

Prof Jansen, who is currently a Senior Research Professor at the UFS and a Fellow at the Center for Advanced Studies in the Behavioral Sciences at Stanford University, is also a Fellow of the American Educational Research Association, a Fellow of The World Academy of Sciences, and President of the South African Institute of Race Relations.

The great achieve greatly
Prof Jansen’s book, Knowledge in the Blood: Confronting Race and the Apartheid Past won the Nayef Al-Rodhan Prize, the largest award from the British Academy for Social Sciences and Humanities, for its contribution to scholarly excellence and transcultural understanding.

In 2013, he was awarded the Education Africa Lifetime Achiever Award in New York and the Spendlove Award from the University of California for his contributions to tolerance, democracy and human rights. He holds honorary degrees from the University of Edinburgh, the University of Vermont and Cleveland State University.

Plans for the future
His recent books include Leading for Change, which was published this year. He is completing a new book explaining the current crisis in, and future prospects of, South African universities, due for release in mid-2017.
