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 Faculty of Theology and Religion recently hosted the annual Tutu-Jonker Prestige Lecture Series at the Bloemfontein Campus of the University of the Free State (UFS). The purpose of the lecture series is to address modern-day and pressing social challenges from a theological and religious perspective.

With the theme Religions and reconciliation of conflicting identities, guest speaker and Desmond Tutu Chair on reconciliation at the Faculty of Theology: Vrije Universiteit Amsterdam, Prof Eddy van der Borght, spoke about the reformation in the context of shifting European identity formations.

Reconciliation versus social identity

 “My focus is on what the Christian concept of reconciliation means for reconciliation in society,” said Prof Van der Borght. He deliberated the global problem of conflict generated by diverse social identities. He also emphasised that religion has huge resources to contribute towards overcoming conflicting identities.

“The theory is that religions know about reconciliation, while in practice it is much more complicated, because often religions are part of the problem of conflict,” he says. He said religions are often the problem in social cultural identities, especially regarding conflict involving different nations, racial, and ethnic groups.

Honouring prominent theologians Tutu and Jonker

 The name Tutu-Jonker originates from the two theologians, Emeritus Archbishop Desmond Tutu and the late Prof Willie Jonker, who are both regarded as prominent theologians known for their emphasis on reconciliation in South Africa. The significance of combining the two names is said to bring together two different theological traditions (Anglican and Reformed), cultural groups, and races.

Prof Fanie Snyman, Dean of the Faculty of Theology and Religion, said, “This will also serve the purpose of a welcoming culture at the faculty, embracing diversity and embodying reconciliation.” Both of these theologians received honorary doctorates in Theology from the UFS.
