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.

“Much has been going wrong in South Africa in the last few years and it’s all due to a lack of strong, visionary leadership. South Africans deserve better and should demand more integrity, courage and vision from the present political leadership,” veteran journalist and author Max du Preez told the audience at a packed Wynand Mouton Theatre at our university, on 25 August 2011.

Delivering this year’s CR Swart Memorial Lecture on the topic “Of Jacob, Julius, Jimmy and the Dancing Monkey”, Du Preez told the audience to look with much more critical eyes at the political leadership and decide who is doing the obvious, following his or her basest instincts or simply trying to play to the gallery. “Why look at a man like Julius Malema and let him upset us, why listen to Floyd Shivambu with his crude manners and let them define us?” Du Preez asked the more than 300 people attending the memorial lecture. The CR Swart Memorial Lecture, the 41st hosted by the UFS, attracted one of the largest crowds ever for a public lecture, with some people sitting on the steps inside the auditorium of the Wynand theatre.
 
Telling the story of African philospher Morena Mohlomi, who acted as a teacher to Basuto king Moshoeshoe, Du Preez told the audience that the country needs counter-intuitive leadership like the two leaders had demonstrated. Calling Mohlomi southern Africa’s first Pan Africanist, Du Preez said the extroadinary thing about Morena Mohlomi and his student was their gift of counter-intuitive leadership, leadership that was daring and visionary, leadership that did not simply do the obvious. Pointing out other visionary leaders like Nelson Mandela, Oliver Tambo, Walter Sisulu, Beyers Naude and Van Zyl Slabbert, Du Preez urged the audience to question “the quality of leadership of Cosatu, the Democratic Teachers Union that is messing up our education, the Communist Party, the Democratic Alliance, the Freedom Front Plus and Solidarity. If they don’t live up to our expectations, why do we still tolerate them?” Du Preez asked.
 
Du Preez also commended Prof. Jonathan Jansen, Vice Chancellor and Rector of the UFS, for his counter-intuitive leadership regarding the Reitz Residence incident and said Prof. Jansen’s solution, as controversial as it was, brought a much better outcome.
