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.

Odeion String Quartet receives international acclaim
2014-12-22

 

The Odeion String Quartet (OSQ) is a flagship of the UFS and symbolises the university’s commitment to the arts. Most recently, the OSQ walked away with the award for Best Classical Music Performance at the 2014 Kanna ceremony.

It was established in 1991 as a permanent full-time resident string quartet –   at present the only resident string quartet at a South African university – and functions as an independent academic department at the UFS.

The members of the quartet are Samson Diamond (leader and first violin), Sharon de Kock (violin), Jeanne-Louise Moolman (viola) and Anmari van der Westhuizen (cello). They have an extensive national and international background and are highly regarded in music circles as soloists and chamber musicians. The members of the quartet play an important strategic role in the development of symphony orchestra music and in classical music training in the Free State. They are exemplary teachers and attract students from all over the country. The Junior Odeion String Quartet and Odeion Sinfonia provide a unique chamber music training experience to selected students.

They regularly perform to critical acclaim in all the major music centres in South Africa, as well as in SADC countries such as Zimbabwe and Zambia. During 2013 they performed at concerts in Belgium, Germany and Switzerland, where they received standing ovations and very positive reviews.

The quartet is also set on giving back to musical communities around the country, with workshops offering guidance on playing techniques and life-skills that are essential for young people who intend to pursue a career in the music sector.
