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.

Leadership and responsible citizenship: key themes at the Global Leadership Summit

Leadership and responsible citizenship have been the main topics of discussion at the Global Leadership Summit which started on 5 July at the UFS Campus in Bloemfontein, and will continue until 17 July. More than 103 international delegates from various universities in Asia, the United States, and Europe, as well as 40 student delegates from the University of the Free State, are attending.

Kick-starting the summit talks was Prof Joel Samoff (Stanford University) who led discussions on transformation in institutions around the world. “Transformation is a constantly-changing interaction.  It is not a single objective, but a process, “ he said. This was followed by a robust panel discussion with student leaders of the UFS and those from James Madison University, Mount Holyoke College, and Rutgers University, who described the journey of transformation at their various universities.  “Young people are leading themselves in a different way, the context of the society we live in has changed,” said a UFS Student.

Keynote speaker, Zelda la Grange, gave an account of her experiences and the colourful journey of discovery of a “different” South Africa, working with President Nelson Mandela for 19 years, a journey that is the subject of  her book, “Good Morning Mr Mandela “. Under the theme “Breathing the same air: A metaphor for human solidarity, Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness, and Reconciliation Studies led a talk with Candice Mama, the daughter of slain anti-apartheid activist, Gelnack Masilo Mama, one of the victims of the former hit squad commander, Eugene de Kok. Candice inspired the audience with her philosophy on life and letting go of trauma: “Forgiveness is a process, and one needs to forgive to be able to be liberated from anger and bitterness,” she said.

Dr Lis Lange, Vice Rector: Academic, UFS spoke of citizenship and freedom, focusing on the responsibility that humans have to create ethical, positive, and meaningful interaction in their daily lives and in their societies across the globe.

As part of the programme, delegates will visit the Qwaqwa Campus on 10 July 2015, where they will interact with the leadership of the campus, its staff, and students, and enjoy an arts and cultural experience of the Eastern Free State.  The summit will end with a visit to various sites in Bloemfontein, where delegates will engage in community-based outreach activities in disadvantaged communities around the city.
