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 provides sign language skills to locals

The public and private sectors are becoming more aware of the need for effective communication between employers, employees, and clients who use Sign Language. Given that Sign Language is the first language of approximately 600 000 people in South Africa, competence in the language means taking the first step towards more inclusive service delivery.
 
Shout Out Loud - a project that promotes Sign Language - has signed up Bloemfontein Celtics, Centlec, Beyond Boundaries, and the Mangaung Municipality on a Basic South African Sign Language course at the University of the Free State.
 
No miscommunication
 
Susan Lombaard, the Acting Head at the Department of South African Sign Language, was one of the lecturers who presented the 40-hour accredited course every Friday from 15 January-12 February 2016. Other lecturers who were responsible for training were Emily Matabane and Tshisikhawe Dzhivani.
 
Lombaard believes that learning Sign Language bridges the gap between the hearing and those who have impairments. “The benefit is that there will be no miscommunication. It happens that a deaf person walks into a bank or municipality offices and there is no communication. They need to write which is humiliating for that person.”
 
Towards a promising future
 
According to Goodwill Mokoena, Project Manager at Beyond Boundaries, the project will continue annually, and a larger intake of government departments and non-governmental organisations is expected in 2016.He also indicated that Shout Out Loud has achieved substantial success in its involvement with the Bartimea School for the Blind and Deaf.

Shout Out Loud selects one pupil every month, and flies them to Johannesburg to interpret on Bloemfontein Celtics’ magazine show. It is the only magazine show in South Africa that has a sign language interpreter. “The school has been achieving 100% in matric results because the pupils are selected on merit. This has enhanced their academic performance in such a marvelous way,” said Mokoena.
