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.

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.

On Thursday 11 December 2014, the university awarded a total of 392 qualifications during our Summer Graduation Ceremony in the Callie Human Centre on the Bloemfontein Campus. Of these, 225 were awarded to graduates from the Faculty of Health Sciences, while 134 master’s degrees and 33 PhDs were awarded in the other six faculties. Another 74 diplomas and 56 certificates were also awarded in the School for Open Learning.

Well-known radio personality, Redi Thlabi, and acclaimed cardiothoracic surgeon, Dr Susan Vosloo, encouraged and inspired the graduates during the two ceremonies on the day.

During the morning session, Thlabi imparted some of the valuable lessons she learned in her personal life as well as in her career. She encouraged graduates to change the script of our country for future generations, to be mindful of others and to find meaning in whatever you do.

“Those who have a platform, a voice and an education have the power to help others further on their journey,” Thlabi said. “I believe we are living in an exciting time – a time to leave a legacy behind, a time to make a mark in this world.”

Graduates from the Faculty of Health Sciences and the School for Open Learning were addressed by Dr Vosloo during the second ceremony.

Dr Vosloo often referred to the success of transformation at our university and added that few successes are achieved without adversity. She encouraged the afternoon’s graduates to become professionals with a high sense of dignity, accountability and transparency in their workplace.

“Remember that you and you alone are able to decide what your approach will be in anything in life from here on forward,” she said.

Dr Vosloo, a Kovsie alumnus, graduated in 1980. Shortly after this, she became the first female heart surgeon in South Africa. She is currently in independent private practice at Christiaan Barnard Memorial Hospital, having also worked from 1998 untill 2012 at the Vincent Pallotti Hospital in Cape Town.
