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 staff and students clean campus together

A group consisting of students, staff and members of the management team of the University of the Free State (UFS) proved that they are not only talking about sustainability and the importance of keeping the campus clean, but they actually put their words to action by taking up a garbage bag and helping to pick up garbage.

According to Ms Martie Bitzer, Head of the Sustainability Committee of the UFS, the UFS followed the lead of higher education throughout the world by joining the movement for sustainability and took the plunge in addressing sustainability issues with both short- and long-term planning. One of the short-term plans is to make staff and students aware of the importance of a “green” lifestyle. This week’s activities, including the picking up of garbage and planting a tree on the Bloemfontein Campus of the UFS, is the result thereof.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, who also helped to pick up garbage, told the group of staff and students that many universities around the world are implementing sustainability initiatives and are keeping their campuses clean, because they care for the environment. He thanked the group for their contribution to this process.

“By cleaning up around us, we show respect towards ourselves and towards our campus,” said Prof. Jansen.

To encourage students to keep the campus clean, Student Affairs at the UFS will launch a competition to see which residence can pick up the most garbage on 8 September 2011. A Clean Thakaneng Bridge Campaign will also be launched later on.
