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.

Victory lies beyond the moment

For Mokoena it was just a regular day. Another day. Another rush. As a taxi driver you get used to the adrenaline, taking gaps, foot on the accelerator. Alert. Honking hooters. Angry drivers.

Then it came out of nowhere. A stroke. The one side of his body was going numb. What was happening? What about his job? His income? His life?

Fast-forward a few years.

I meet Mokoena at the Learning Festival arranged by the Centre for Community Engagement, in association with Bloemshelter on the University of the Free State’s Bloemfontein Campus. A reserved young man, Mokoena is busy at one of the stands where a range of people from rural communities come to learn new skills. At no cost. They then go back to teach the skills they learnt in their communities. Job creation, that’s the philosophy: as you develop, you need to develop others. 

When I talk to Karen Venter, Head of Service Learning at the Centre for Community Engagement, the stories are overwhelming. “There was the lady who attended 19 workshops in two days. She went back to her community, shared her knowledge and became an entrepreneur helping others take care of themselves.”

New skills
Mokoena is also here to acquire new skills. After his stroke he was told by occupational therapy students about a project that teaches you to build your own house with raw materials. He takes out his cellphone with a sense of pride. Scrolls through some pictures: “This is my house. I built it from all kinds of things, cow manure, bottles, clay, other people’s rubbish.” The pictures show a house in a neat environment. Solid. Proud. A lot of healing came with building the house. Karen explains: “The physical work he was doing, pushing a wheelbarrow and working, but more than that – the knowledge that he could take charge, make a difference, work on a dream – the healing power of a sense of purpose. He became stronger and more confident.”

Victory 
Mokoena walks back to the sewing workshop he was attending before sharing his story. The buzz continues inside the Equitas Building where artisans, entrepreneurs and UFS staff are sharing their skills. Sewing machines hum away and infrequent beeps sound from a table where an excited group of non-scientists have just completed the building of circuits. Faces light up with every beep. Hands raised. Fists clenched. Victory!

But the victory lies beyond the moment. It’s in the confidence, the learning, and the sharing that will be taking place when these people go back to their communities. Some will participate in research projects; others will benefit from curricular requirements leading students into distant communities, and others will be hosting workshops at the next Learning Festival. 

And there will be more great stories. Like Mokoena’s.
