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.

New facility helps with better clinical training

When you visit the School of Nursing at the Bloemfontein Campus of the University of the Free State (UFS), you will be alarmed by all the casualties and patients being treated here daily.

There are patients with serious penetration wounds, as well as open and laceration wounds which could be fatal if not attended to urgently.

In one ward a child is being treated for breathing difficulties and in the emergency ward a patient who suffered a heart attack has just been rushed in.

At the end of the session students pack up their textbooks and the ‘patients’ are re-programmed and prepared for the next group of nursing students to practice their clinical skills.

The School of Nursing recently had the official opening for their Authentic Learning Space where they showcased their state-of-the-art patient simulation rooms.

In each of the many examining rooms as well as in the high-care rooms there are simulation mannequins that can be programmed for certain medical conditions or for medical emergencies.

Speaking at the opening of the Authentic Learning Space, Prof. Driekie Hay, Vice-Rector: Academic, said universities are often accused of not preparing students adequately for their careers.

“We know students learn better by interaction. With access to authentic learning spaces, students are able to gain a deeper sense of a discipline and they can begin to grasp the unwritten knowledge of practice that is often used on a daily basis.”
