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.

Department at the UFS receives special visitors

The Department of Old Testament in the Faculty of Theology at the University of the Free State (UFS) has for the first time received a visit from two guest professors from the Katholieke Universiteit Leuven (KU) in Belgium who are presenting undergraduate lectures.

What makes the visit even further unique is that the guest professors are a married couple who specialise in the Old Testament.

“Proff. Hans Ausloos and Bénédicte Lemmelijn are visiting the faculty for about a month to present undergraduate programmes. They are part of a co-operative agreement between the UFS and the KU Leuven. This is also a good way of giving our students exposure to European experts,” says Prof. Snyman, Head of the Department of Old Testament at the UFS.

The couple and their three children, Matthias (10), Elke (8) and Ruben (6), are staying in Prof. Daan Pienaar’s house for the duration of their stay. Prof. Pienaar is a retired professor in Biblical Science at the UFS. The children are at school in Universitas Primary School for the duration of the family’s stay in Bloemfontein. “The headmaster was very kind and provided them with school uniforms out of the school’s second hand clothing shop, of which they will not part easily as they do not wear school uniform in Belgium,” says Prof. Lemmelijn.

Proff. Lemmelijn and Ausloos cannot stop talking about the charm of the university’s Main Campus. “In Leuven the university is part of the city and the university buildings are situated amongst the city buildings. We do our shopping while the students move from one class to the other! Here, the university is a town on its own and the students are given the opportunity to socialise in a protected environment,” says Prof. Lemmelijn.

The couple is also just as impressed with Bloemfontein. “The safety issue in South Africa is accentuated in such a way in Europe that we are astounded by the peaceful and friendly atmosphere of the city. We are also surprised with the shopping centres that are under one roof. In Belgium the shops are situated far apart,” says Prof. Lemmelijn.

The couple finds the living costs – especially food – to be quite expensive. “Some basic food is even more expensive than it is in Belgium,” says Prof. Ausloos.

Over and above their commitment to lecture, the couple is also busy with research on the Greek translation of the 12 Small Prophets in co-operation with Prof. Snyman.

“This is the first time that lecturers from the KU Leuven visit the Department of Old Testament for such a long time and are part of the normal curriculum. It is interesting to note that the teaching modules between the two departments resemble each other in such a way that lectures which are presented in Leuven are also repeated here,” says Prof. Snyman.

Both Proff. Ausloos and Lemmelijn are professors in the Old Testament within the Bible Science Investigation Unit of the KU Leuven. They publish articles internationally on the editorial and text criticism of the Old Testament and are involved with international investigative programmes such as the Hexapla Project and Septuaginta-Deutsch. Prof. Ausloos is director of the Leuvense Centre for Septuagint Studies and Textual Criticism and Prof. Lemmelijn is an associate in the centre. Together they have published several financed investigative projects on the characterising of the translation technique of the Greek Bible translation.
