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.

Superior Scholarship. Human Embrace. Institutional Distinctiveness. Emergent Leadership. Public Service.

These are the core values underpinning both the university’s academic and human projects. It is the last one, public service, that resonates well with Dr Marian Human-Nel. She does her part as a radio presenter and news reader on Maluti FM 97.1, a Bethlehem-based community radio.

“As a community radio station, we are not only responsible for entertaining and informing the public, but we also do a lot of community fundraising projects. We also do a lot of wellbeing activities in the Eastern Free State,” said Dr Human-Nel, Subject Head and Lecturer in the Department of Afrikaans, Dutch, German and French on the Qwaqwa Campus.

Sharing of information and knowledge
Dr Human-Nel volunteers her services as presenter of two programmes. “I present Kollig in which I invite my Qwaqwa Campus colleagues and professionals in the community to talk about their specific fields of interest and research. The focus here is on information and sharing knowledge. We have a slot called ‘This Week in History’ written and prepared by my colleague from the History department.”

Another show that Dr Human-Nel presents is called Fluit-Fluit Storietyd on which she reads and does voice performance of Afrikaans short stories and poems with specific music. “The Fluit-Fluit programme informs and entertains through cultural activities,” she said.

Maluti FM broadcasts over a 160-kilometre radius around Bethlehem and is also available online.
