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.

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.

Bloemfontein Campus hosts annual HELTASA conference

This year, the privilege to host the annual Higher Education Learning and Teaching Association of Southern Africa (HELTASA) conference was afforded to our university. The event took place on the Bloemfontein Campus from 18 – 21 November 2014, attracting keynote speakers and members from across the world.

HELTASA is a professional association mainly for educators and significant role players in higher education institutions. With its inception in the early 2000s, it has grown to become the premier organisation for teaching and learning in Southern Africa, Dr Amanda Hlengwa, President of HELTASA, pointed out.

A central concern of this body is issues around success within the tertiary sector. The theme of this year, ‘Accessing success: using evidence for change’ served to focus members’ attention on what works and what does not work – as derived from researched evidence.

In a message from Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), he stressed that the task as university teachers “is not simply cognitive gains that ensure graduation success but also intellectual gains that ensure success in life during and after university studies.”

The conference was led by internationally-acclaimed keynote speakers, namely Prof George Kuh, Prof William Grabe and Prof Fredricka Stoller, as well as our own A1 NRF-rated Prof Malanie Walker.

Prof Kuh is Adjunct Research Professor of Education Policy at the University of Illinois and Chancellor’s Professor of Higher Education Emeritus at Indiana University. In his keynote address, Prof Kuh offered valuable lessons from the field to promote student success.

Profs Grabe and Stoller collectively presented the second keynote address that explored how to set up students for success through strategic-reader training. Prof Grabe is Regents’ Professor of Applied Linguistics and Vice President for Research at Northern Arizona University. Prof Stoller is a Professor of English at Northern Arizona University, where she teaches in the MA-TESL and PhD in Applied Linguistics programmes.

Prof Walker is a Senior Research Professor at the UFS Centre for Research on Higher Education and Development (CRHED). She is also currently Director of Research Training and a senior researcher in the EU-funded Marie Curie EDUWEL project. In her keynote address, Prof Walker looked at well-being and agency in higher education.
