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.

Two Kovsies crowned at Miss Deaf SA

The new Deaf Miss South Africa was announced – and Elzane van den Bergh, a Kovsie student, was crowned the winner. Elzane, a final-year BEd Foundation Phase student, also won the title for Best Talent at this swanky event.

Another Kovsie student, Elrie du Toit, was selected as second princess. She was also among the top five for the Best Talent title. Elrie is currently studying to become a social worker.

Twelve finalists from all over South Africa, all deaf or hard of hearing, took part.

On the competition at Miss Deaf South Africa, Elzane’s thoughts are that the judges had a very difficult choice to make. “Each talented girl had some special characteristic that stood out,” she relates.

“I really wanted to do something like this as it would help to make a bigger difference in the community and motivate people to accept themselves for who they are, because we are all uniquely created.”

Elzane’s focus is on teaching basic sign language to hearing parents with deaf babies. She also believes that hearing people should be made more aware of the deaf culture and language. This will eventually lead to deafness no longer being perceived as a disability.

Hard work and preparations are now lying ahead for Miss Deaf World, which will be held in Prague during June next year.

“Never allow any disability or obstacle to stand in the way of your dreams,” says Elzane. “Stick it out and don’t doubt in your abilities for one second, because you were born to be a winner. Be proud of yourself, no matter what.”
