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.

SA and Indonesia strengthen educational ties

“Indonesia and South Africa share one common trait which is diversity,” were the opening remarks of Suprapto Martosetomo, ambassador of the Embassy of Indonesia to South Africa. The ambassador drew parallels between the two republics at a public lecture hosted by the Department of Political Studies and Governance at the University of the Free State Bloemfontein Campus on 10 May 2016.

Professor Ikrar Nusa Bhakti, Research Professor in the Indonesian Institute of Sciences, presented the lecture on “Managing Political Diversities: The Indonesian Experience.” He outlined the history of Indonesia’s political and economic development, political system, and government’s policy in dealing with political and economic challenges, as well as the lessons learned from its experience.

Diversity and governance
As is South Africa, Indonesia is a ‘rainbow nation’. Being the largest country in the Southeast Asia, it boasts a population of approximately 250 million people, 300 ethnic groups, and 650 local languages. However, despite such diversity, the nation has been united behind the motto of “unity in diversity”, which was adopted when Indonesia proclaimed its independence in 1945.

Indonesia and SA also bear similarities in terms of a multiparty parliamentary system. Their current Joko Widodo and our Jacob Zuma administrations are governed by policies including anti-corruption, economic prosperity, equity and equality, quality education and healthcare, and maintenance of security.

International relations
The two countries have a long-standing relationship since 1955 when the Asia-Africa conference was held in Bandung, Indonesia. The conference represented solidarity against colonisation.

Prof Hussein Solomon, Senior Professor at the UFS Department of Political Studies and Governance, attributes Indonesia’s success as a product of education and leadership - something South Africa could learn from..“Indonesia like SA has been struggling with how to balance social diversity, democracy, and a political system. Despite this, they have managed to develop a functioning democracy and a vibrant economy. They are one of the top 20 economies in the world, and by the year 2035 will be in the top seven economies in the world, according to the Goldman Sachs, report,” he said.
