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.

Rag teamwork leads to Armentum, Emily's float

Perhaps the residences Armentum and Emily Hobhouse were thrown into the deep end, but they still wanted to prove a point.

This is according to Hanko Minnaar, Residence Committee member for Rag at Armentum, shortly after the residences were announced as overall float winners of the University of the Free State (UFS).

According to Minnaar, Emily Hobhouse and Armentum overcame the challenge of building a float as a two-residence team, while most of the other hostels were in teams of three.

On 30 January 2016, after about two weeks of hard work and sweat, the residence twosome was named the winner at the Bloemfontein Campus.

“I am very proud. We couldn't have asked for more,” Minnaar said, after the residences Armentum and Emily Hobhouse celebrated their victory with house songs. “Anything is possible through teamwork.”

Tom and Jerry, Olaf and a Steri Stumpie

 The theme for this year was “Cartoons, Animation, and Children's Snacks”. Among other items, Armentum and Emily Hobhouse had Tom and Jerry, Olaf from Frozen, a Steri Stumpie, and a box of Astros on their float.

“We thought hard about what we wanted,” Minnaar said.

“We also asked some children, and they said that Tom and Jerry is a favourite, and Olaf has always been a winner as well. And Steri Stumpies, of course. Who doesn't like Steri Stumpies?” The residences Marjolein, Veritas, and Akasia were second overall, with Karee, Vergeet-My-Nie, and Sonnedou third.

Colourful processions

The events of the day started off with a morning procession from the Pelonomi Hospital to the Twin City Mall in Heidedal, where students and the community celebrated together, and meals were distributed.

The evening procession, from the Tempe robot in Nelson Mandela Drive to the Old Grey Sports Grounds, was greeted by hordes of spectators along the way.

Artists and Co captivate audience

In the evening, music lovers were entertained at Old Grey Sports Grounds by the legendary artists Vusi Mahlasela, the talented Karen Zoid, and an energetic Francois van Coke.

Local bands, Rise in Red and Simple Stories, added to the excitement. To top it all off, a special laser show made for a colourful visual bonus, coupled with great sound.
