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.

Art and science help us understand the world and our place in it

Although BioArt dates back as far as the 15th and 16th centuries with the work of Leonardo da Vinci, it is not every day that art and science combine. This rare phenomenon made its appearance when two totally different groups of students – studying arts and microbiology respectively – joined hands in an initiative to create BioArt.

This first-time undergraduate teaching collaboration between the Departments of Fine Arts and Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), which is characterised by the use of living materials, such as enzymes, microbes and DNA, as well as scientific tools and methods, is exploring a number of questions. 

Different outcomes for arts and microbiology students

According to Prof Carlien Pohl-Albertyn from the Department of Microbiology, Biochemical and Food Biotechnology, one of the central questions explored in BioArt is the nature of ‘life’. “At which stage can matter be classified as being alive or living?” she asked. 

“We realised that the outcomes for the two groups of students would not be the same. For the microbiology students, the focus would be on the understanding and effective communication of a microbiological concept. For the art students the focus would be on the execution of the assignment using visual elements and applied theory of art,” said Prof Pohl-Albertyn.

Dr Janine Allen-Spies from the Department of Fine Arts added: “Art students will also be exploring strangely or previously unforeseen gaps between art and science that can be filled with imaginative interpretations which may forward creative insights in both BioArt as a developing art form and microbiology as investigative science.”

Students’ understanding of microbial evolution reflected in art
The art students had to visit the microbiology labs for their assignment as this is mostly a foreign environment for these students. “The paint medium they had to use was gouache. This medium with its bright colours works well to depict microscopic organisms in art,” Dr Allen-Spies said. 

On display at the Department of Microbial, Biochemical and Food Biotechnology on the Bloemfontein Campus, at a recent event to introduce this new initiative to a wider audience, was a range of visually and scientifically compelling paintings and artefacts (such as paintings, poems, songs, apps) which explore a theme within microbiology from a BioArt perspective that uses creativity to communicate concepts dealt with in the module Microbial Evolution and Diversity.

Any parties who are interested in buying the art can contact Dr Allen-Spies at allenj@ufs.ac.za.

Paintings and artefacts reflects students understanding of BioArt. At the recent opening of the BioArt exhibition at the UFS Department of Microbial, Biochemical and Food Biotechnology, was the work of Madeleen Jansen van Rensburg on display.

Pheny Mokawane, a Microbiology, Biochemical and Food Biotechnology student, wrote a poem for his BioArt project in the Microbial Evolution and Diversity assignment.
