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.

Kovsie community pledge to advance equality and eradicate racism

On Monday 13 April 2015, the University of the Free State drew a line in history. Staff and students united in a singular vision: equality.

Since March 2015, the Institute for Reconciliation and Social Justice, together with the SRC, has launched the No-to-Racism/Yes-to-Equality Campaign across all three campuses with tremendous success. This campaign has now reached a high point at which the Kovsie community pledge their commitment to entrenching a culture of equality at the university. The first pledge ceremony took place on 13 April 2015 at the Bloemfontein Campus. Kovsies thronged to place their inked thumbprints on pledge posters in an inspirational show of solidarity.

“The key to transformation,” Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said, “is putting yourself in the shoes of the other person.” When you look past yourself and acknowledge others’ experiences, the world starts to look different. A pledge, Prof Jansen continued, is a solemn promise – not only to stop bad behaviour, but to go forward resolutely with good behaviour. “You do not change a campus, you do not change a country, without being courageous,” Prof Jansen said.

The message from Mosa Leteane, President of the Student Representative Council (SRC), echoed the same belief. “Today,” Leteane said, “the UFS takes a bold and courageous step toward equality.” This new generation, which includes young people from all races, has started a new revolution. A generation that says no to discrimination and yes to equality. “We cannot afford to be ignorant or indifferent,” Leteane urged.

The remaining two campuses will also have an opportunity to publically pledge their support on the following days:
Qwaqwa Campus: Wednesday 15 April 2015
South Campus: Friday 17 April 2015

To enable the university to go beyond dialogues and consultation towards active decision-making, a University Assembly will be held on Tuesday 28 April 2015. The assembly will serve as a space for critical engagement among all university stakeholders to focus on issues such as symbols, policies, practices, and curriculum. Staff and students are encouraged to submit matters for discussion to JC van der Merwe (vdmjc@ufs.ac.za) before 22 April 2015.

The No-to-Racism/Yes-to-Equality Campaign is aligned with the declaration made by the UFS Council in November 2014, in which it states that “the Council of the University of the Free State believes very strongly in the human dignity, equality, and freedom of all people.”
