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.

Prof Jonathan Jansen: Lecture

The university celebrated the life of one of South Africa's most renowned art critics, hosting the 2013 English Academy’s Percy Baneshik Memorial Lecture on the Bloemfontein Campus.

The keynote lecture was delivered by Prof Jonathan Jansen, Vice-Chancellor and Rector, who joined a distinguished list of speakers to have delivered the lecture. Presented annually by the English Academy of Southern Africa, an association dedicated to promoting the effective use of English as a dynamic language in Southern Africa, past speakers include Prof Es’kia Mphahlele, Prof Njabulo Ndebele, Dr Alan Paton and Prof Albie Sachs. The lecture is hosted at venues across the country and this year Bloemfontein paid tribute to Percy Baneshik.

In his speech Not even colonial born: England, the English and the problem of education in South Africa,' Prof Jansen addressed the dilemma of the politics of language in both school and university education today.

Talking about the dominance of English in schools, Prof Jansen said it is the language of choice because indigenous languages are so poorly taught. "Simply learning in your mother tongue is absolutely no guarantee of improved learning gains in school. The problem is not the language of instruction; it is the quality of teaching, the knowledge of curriculum and the stability of the school."

Prof Jansen told the audience in the CR Swart Hall that Afrikaans-exclusive, or even Afrikaans-dominant white schools represent a serious threat to race relations in South Africa. "You simply cannot prepare young people for dealing with the scars of our violent past without creating optimal opportunities in the educational environment for living and learning together."
