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.

UFS trains Kovsies to become great in world terms – Prof Jonathan Jansen

The University of the Free State (UFS) does not train Kovsies to become great in Bloemfontein or even South Africa. The UFS trains them to become great in the world.

With these words, Prof Jonathan Jansen welcomed the first-year class of 2016 to the “home of Wayde van Niekerk, Rolene Strauss, and the 2015 Varsity Cup rugby champions”.

Prof Jansen, Vice-Chancellor and Rector of the UFS, welcomed the newcomers to the start of the “best time of their lives” on 15 January 2016 at the Red Square of the Bloemfontein Campus. First-years and their parents attended the annual welcoming ceremony.

Prof Jansen congratulated the students on choosing the UFS, and on being part of the elite group that was selected to study at the university.

The UFS received 25 142 applications from newcomers, he said, although there are only about 8 000 places. In 2015, there were roughly 17 500 applications.

He said it was also the most diverse group of applications the UFS had ever received.

Access to education

According to Prof Jansen, the UFS is committed to helping poor students gain access to education, no matter what their background or the colour of their skin.

Lindokuhle Ntuli, the UFS Student Representative Council (SRC) President, said higher education should be more accessible. He said South Africa has allowed education to become commercialised.

“The sooner we as a country realise education isn’t an expense, but rather an investment, the better,” he said.

UFS campaigns

Prof Jansen thanked the UFS SRC for the Right to Learn (R2L) campaign. Launched by the SRC on 30 October 2015, this campaign has already raised R1.2 million to help academically-deserving underprivileged students to study.

“I have launched a campaign myself to raise R100 million between now and September. About 50% of my time will go into this,” Prof Jansen said.

“I will work tirelessly with Lindokuhle and the SRC to raise money.”
