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 Department of Computer Science and Informatics motivates programming success among learners
2015-04-23

A group of learners from the Free State, who are taught at and by the University of the Free State’s Department of Computer Science and Informatics (under the Python project), came first in the Talent Search round of the South African Computer Olympiad (SACO).

According to Dr Anelize van Biljon, senior lecturer in the Department of Computer Science and Informatics, the Olympiad is presented in three main rounds: the Talent Search, the Application Olympiad, and the Programming Olympiad.

At the UFS’s Department of Computer Science and Informatics’ Python project, pupils from various schools in Bloemfontein attend programming classes where they are taught by staff and students of the department. These students are benefitted by the opportunity to transfer their knowledge to others. All the classes are free of charge.

Anelize explains: “The name was chosen because we use the Python programming language. It is a language with considerable appeal – not one of the fastest – which can be learnt relatively quickly, and which conforms to SACO requirements. The purpose of this programming is to implement algorithms (the learner is given a problem, makes a plan to solve it, and does the necessary programming). Thus, it is not about the looks of the programme, but about its effectiveness and speed.”
Anelize is the initialiser and co-ordinator of the Python project. "I started this project in 2010 in the Department of Computer Science and Informatics for learners from Grades 6 to 12 to encourage them to take the subject. These classes exposed them to something more than school work. I enjoy this kind of competitions and am also very involved with Maths Olympiads.

Achievements such as these are good advertisements for the Department of Computer Science and Informatics,” she said.
