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.

MSc student plans to FEED our hungry planet

Since attending the 2014 Youth Ag-Summit in Canada, Lisa Coetzee – an MSc student in Plant Pathology in the Department of Plant Sciences at our university – developed a plan to address hunger:

FEED – Forum of Education, Empowerment and Development.

Coetzee, together with a junior lecturer at Plant Sciences, Marguerite Westcott, started this student association to tackle the issue of food insecurity head-on.

Education, empowerment and development “are keywords vital to the solutions to poverty. Hunger is an issue which is found in our own homes. One in every four South Africans is food insecure. Hunger kills more people every year than Aids, malaria and TB combined,” says Coetzee.

“This forum allows awareness to be raised about the hunger situation locally and globally. FEED is talking about hunger and it is assisting in reducing it by reaching out to communities which are in need.

“FEED is the generation which is going to make a difference in eradicating hunger,” Coetzee continues. “We want students to think about how they can feed the hungry through what they are studying”. For Coetzee it is a high priority to ensure that the youth are aware of the importance to feed our hungry planet in a sustainable way.

Her philosophy on relieving hunger and increasing food safety is to enhance the efficiency of crop production, ensure crop security and reduce mycotoxins in the food we eat.

During the 2014 summit, Coetzee was elected to represent the African delegates on the Youth Ag Summit Committee. Ever since, she has been enthusiastically active in the agricultural community. As 43% of the globe’s farmers are women, Coetzee also feels she acts as a voice for female farmers in South Africa.

An important lesson Coetzee has learned is that there is power in one person to make a change – that we should start small but think big.
