Mathematician makes popular contribution to science Prof Atangana

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.

Centre for Africa Studies launches its ANC Centenary Seminar Series

The Centre for Africa Studies at the University of the Free State (UFS) recently launched its series of seminars commemorating the centenary celebrations of the African National Congress (ANC). The launch of the series took place on 30 November 2010, with the seminar series running from February 2011 until February 2012, the year of the centenary celebrations of the ANC.

Along with UFS staff members and students, various special guests also attended the launch of the seminar series, including former Premier Ms Winkie Direko, representatives of the office of the current Premier and the Vice-Chancellor and Rector of the UFS, Prof. Jonathan Jansen. Prof. Jansen praised the Centre for Africa Studies for its vision in establishing the seminar series and added that he would be a regular attendee when the seminars kicked off in 2011.

The seminar series is the brainchild of Prof. Kwandiwe Kondlo, Head of the Centre for Africa Studies at the UFS. Prof. Kondlo explained that the aims of the seminars were to delve into the legacy of the ANC from a firm historical perspective, as well as to develop a firmer understanding of the dynamics of contemporary South Africa. He stressed the scholarly and academic nature of the seminars, hoping for robust and critical debate amongst future audiences about the topics at hand. Publications in journals and books at the end of the series will be the secondary objective of the Centre.

The three guest lecturers for the launch were Dr Pule Matjoa, Prof. Chris Landsberg and Herbert Maserumule. Dr Matjoa, an ANC veteran, elucidated the history of the party from an insider’s perspective while Prof. Landsberg spoke about the past and present foreign policy of the ANC. Mr Maserumule examined the ruling party’s economic thinking, with special focus on the distinctions between a democratic and developmental state.

The question-and-answer session after the lecture produced lively debate, which set a premise for the rest of the series. The first seminar in the series will take place on 4 February 2011.
