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.

Artistic development at UFS to transform the face of Bloemfontein creatively
2015-07-02

The 7-metre high ‘Urban Fox’ is one of Alex Rinsler's artworks adding a fragment of the wild to the city of Shanghai in China.

Bold, bright, and beautiful public art sculptures are in the inception phase at the university’s Bloemfontein Campus. Manchester-based public artist, Alex Rinsler, of the Programme for Innovation in Artform Development (PIAD)’s forum for artist development, is to install three enthralling sculptures in the city of Bloemfontein.

The PIAD forum for artist development is an initiative of the Vrystaat Arts Festival, formerly known as the Vryfees, which aims to celebrate art in the Free State by hosting experimental art practices. In its capacity as a PIAD partner, the University of the Free State promotes increased access to, and participation in, culture as a form of human development.

Presenting an artist’s talk titled ‘Urban Safari: Art in public space,’ on the Bloemfontein Campus recently Rinsler introduced himself and his creative ideas to students, staff, and the public at the Johannes Stegman Art Gallery. The talk served as an invitation to the active participation of Bloemfontein citizens in all phases leading to the installations. Dispersed across the Mangaung Metropolitan, the giant sculptures are intended to capture and reflect different aspects of the community’s lived experiences. 

As a public artist based in the United Kingdom (UK), Rinsler has exhibited in cities nationally and internationally, with the intention of bringing a touch of the wild to urban lives. His vision is to witness the development of cities into cultural boulevards, and explore “what we can do to bring back the sense of nature, the wild” by adding new symbolism to urban lifestyle.

“I believe in creating work accessible to the public, which stimulates conversation,” said the Clore Leadership Programme Fellow (University of Manchester) and Founder of Pirate Technics - an artistic practice company.

In 2012, he worked with 31 Master’s students from 24 countries on an icon for global peace named “Under the Baobab” in London. The colourful and magnificent Baobab tree made from pieces of fabric representing distinct cultures told the story of migration to London.

Rinsler is determined that the Bloemfontein “project, similar to the London installation, will create imagery that people will remember.”

Dr Ricardo Peach, Director of the Vrystaat Arts Festival and PIAD, hopes the project fosters diversity while producing a “communal cultural product." 

“What I know about Alex’s work is that he will be working with what he calls a self-selected community, people who are interested in this, and who want to work together to build these sculptures, as part as a process for them to get a sense of where they belong, and their input into the city. It’s about people telling their own stories.”

The public installations are a way of transforming the landscape, and connecting people of “a place like Bloemfontein where communities are often still so divided,” said Peach.
