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.

Digital Storytelling empowers and liberates students
2014-10-17

In January 2014, Jode Brexa, an American Fulbright scholar, came to our university and moved into the guest room at Welwitschia residence.

It so happened that Brexa and Elize Rall, residence head of Welwitschia – better known as Wel-Wel – started talking about digital storytelling. Brexa’s Digital Storytelling project captured Rall’s imagination. Shortly thereafter, Brexa convinced the RC members of Wel-Wel to participate in the project.

Digital storytelling is, on the most basic level, the use of computer-based resources to tell stories. The idea is to combine the art of storytelling with multimedia – including graphics, photos, text, audio, image and/or music.

The Wel-Wel students were taught storytelling skills and each student’s unique story was recorded and edited. It was so successful that they then showed their stories to the Rector and Dean of Students. Brexa will now – with their permission – take their stories to America with her, where she will share it with her community.

During the weekend of 10–12 October 2014, the RC of Wel-Wel introduced 12 learners, who are currently in Grade 10 at the Christiaan Liphoko School, to the project. The learners stayed in the gazellie for the weekend and, in the course of a few days, learned how much power is locked up in their personal stories. They learned that everyone’s story has the power to inspire and empower.

Wel-Wel has been involved in various outreach projects to the community. However, this was the first time that Wel-Wel literally brought the community to their doorstep. This is also not a charitable project. It is uplifted students reaching out to the youth to empower them in order to empower others in turn.

Meanwhile, Brexa also linked the project to the university’s Schools Partnership Project. The programme works through mentorship programmes to uplift previously disadvantaged schools. Hands were also taken with Columba Leadership NGO – financed by Old Mutual.
