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.

Eminent Chinese musicians perform at Odeion
2011-03-08

Hing fat-Wong

A renowned and well-known award-winning Chinese musician from Hong Kong, Hing fat-Wong, enchanted music lovers of the classical genre, after joining forces with Frankie Feng, Music Director of Free State Orchestra of Chinese Music (FSOCM), live on stage at our university’s Odeion for the first time in 30 years. Wong and Feng lit up the stage, to a full house, with an outstanding orchestral performance at the FSOCM’s first concert for the year, called Ancient Chinese Classical Music. Wong was invited by the FSOCM in January 2011 to play solo pieces on the traditional Chinese instruments, the pipa and guqin.

Wong conducted two works, Shanbei Suite and Variations on Yang Guan. Both were arranged by Feng and are based on Chinese folk songs and ancient melodies, respectively. According to Wong, ancient melodies refer to all music before the 1911 Chinese Revolution. However, Wong stated that Feng’s arrangement gave new life to these melodies, as played by the FSOCM.
 
Wong proved to the audience that his talent goes beyond the conductor's baton, and includes his ability to play instruments such as the pipa and guqin masterfully, by performing several solo pieces using these two traditional Chinese instruments.
 
During his stay in Bloemfontein, Wong was invited by Prof. Nicole Viljoen from our Department of Music to host a successful seminar on the appreciation of Chinese music. Attendees had the opportunity to listen to a lecture by Wong and gain first-hand experience of classic traditional Chinese instruments being played. The FSOCM is a multi-cultural orchestra and looks forward to hosting more high-quality performances with soloists of the calibre of Wong throughout the year.
