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.

South Africa could see an increase of 78% in the number of cancer cases by 2030 and from a global perspective, a 75% increase is expected, increasing the total incidence of all new cancer cases from 12.7 million in 2008 to 22.2 million by 2030, according to a recent study published by medical journal Lancet. According to the Cancer Association of South Africa (CANSA), more than 100 000 South Africans are diagnosed each year. It is rather comforting that the University of the Free State’s (UFS) Faculty of Health Sciences has an Oncology department that has been fighting cancer for 50 years. 

Excellence over the decades 
The 50-year celebration of the Department of Oncology took place at the UFS Centenary Complex on the Bloemfontein Campus on 19 August 2017. The auspicious event was attended by UFS Faculty of Health Sciences registrars, radiation oncology radiographers and professional nurses who had trained in the department over the past 50 years, as well as the current departmental staff.

Dr Alicia Sherriff, Head of the Department of Oncology welcomed the dignitaries and thanked everyone for their attendance and dedication to the department, Prof Louis Goedhals, the oldest surviving head of department, gave a summary of the 50 years. He said once you were involved with this department you became part of a family that would carry and support you. Memories were shared and friendships rekindled. The message of this department that stood the test of time was: “To cure sometimes, to relieve often, to comfort always … and to bring hope”.

UFS dignitaries reveled in the moment 
Among the special guests were the Rector and Vice Chancellor, Prof Francis Petersen, Prof Gert van Zyl, Dean of Faculty of Health Sciences; the Free State MEC for Health Mr Butana Komphela, and CEO of Universitas Hospital Dr Marcus Molokomme, were invited. The function was well attended by personnel, graduates from as far as Portugal, and dignitaries from the university. There was a sense of unity and belonging among all the attendees and enthusiastic catching up over the years that have passed.
