Chris Vorster
Chris was on stage in 'Die Hart Verklap' at the Toyota US Woordfees in Stellenbosch recently.

“Difficult and very strange,” is how Chris Vorster, veteran actor and Drama lecturer at the University of the Free State (UFS) describes his role as Bas Koorts in the supernatural thriller Die Spreeus

For Chris, the biggest challenge during the filming of Die Spreeus was to work in front of a green screen. “You never see the monsters and things attacking you, it is only added later on during the editing process,” he said. Therefore, he and his co-actors were expected to use their own imagination “to be frightened, and to duck and dive from something that does not exist.” 

This Afrikaans thriller series has recently been nominated in five categories of the South African Film and Television Awards, including Best Television Drama, Best Cinematography, and Original Sound and Sound Editing. 

Chris was also nominated for a Fiësta award in 2019 for his one-man performance in the theatre production, Die Hart verklap. “It is fantastic to still be recognised for my work,” he said, “but I also have to give recognition to Dion van Niekerk, because without a good director, any actor will be lost.” Van Niekerk also lectures Drama at the UFS.

Being a lecturer broadens his knowledge 

Chris joined the UFS Department of Drama and Theatre Arts in 2015 as lecturer in the programme for Film en Visual Media. “Everything I learn in the industry I apply as lecturer, and research and teaching feed more knowledge on acting, directing, and especially writing,” he said. After five years, being involved with the UFS Department of Drama is still exciting to him. “This is where both lecturers and students get encouraged to do more than just breathing.” 

With his busy schedule of teaching and acting, it remains important to him that South Africans are still able to tell stories – “in any language”. He considers it a privilege for anyone to work in their mother tongue. This is also why the symbiosis between his work as actor and lecturer is so appealing.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
