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 a much safer place

Students and staff at our Bloemfontein Campus can feel even safer, with several initiatives being put in place to ensure their safety.

The stop-and-search actions of the recent past, which are being carried out at all the main gates of our Bloemfontein Campus, seem to be successful, since car theft has decreased on the campus. Mr Willie Frankim, Head of Protection Services, says the stop-and-search actions are carried out sporadically, but have a definite effect on crime at the campus. Mr Frankim says only one vehicle has been stolen in the past two months as opposed to the many more that have been stolen in the past.

The message that safety is viewed in a serious light reaches as far as our university’s parking areas and walkways, which are being patrolled by security staff. Mr Frankim says a security officer is placed in all the large parking areas, while other personnel are distributed across the entire campus, especially at key areas, such as at the library and student centre.

Our university also recently installed more than 30 red poles across the entire campus. Each of these red poles is fitted with a panic button by means of which help can be summoned. Should a student or staff member feel unsafe, all they have to do is press the button and cameras, which are installed in the vicinity, will focus on the pole and Protection Services will send assistance. Twenty five of these poles are already working and ten more still have to be activated.

Students and staff can also phone Protection Services on 051 401 2911 if they feel uncomfortable about their safety. They can use this number, for example, to ask a security officer to accompany them to their car.
