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 Tennis team defends proud USSA record in Cape Town

Duke Munro already has six gold medals from the USSA Tennis Tournament in his cupboard, and the Kovsie Tennis team would wish to bid him farewell in a fitting manner during what will probably be his last tournament in Cape Town.

This year's tournament, taking place from 30 November to 4 December 2015, will probably be Munro's last, since he is completing his Master's degree in Quantity Surveying at the University of the Free State (UFS).

He has competed in the USSA Tournament since 2009, and would like to help his team defend its proud record.

UFS aim for ninth consecutive title

Kovsies have won gold at the USSA Tournament for the last eight years. They are the only team who have been able to win the tournament since the combined format was adopted in 2010. In 2007 and 2008, their Women's team won the tournament, and in 2009, their Men's team.

Kovsies will play in group matches against the Universities of Venda and Wits on 30 November 2015, against the University of Cape Town's (UCT's) second team on 1 December 2015, and against UCT's first team on 2 December 2015. The cross and knockout matches will be played on 3 and 4 December 2015.

Other sporting codes

The Sevens Rugby team from the UFS will compete in the USSA Tournament in George on 30 November and 1 December 2015.

For the past two years, the team has won bronze, and will be playing three league matches on 30 November 2015 against the North-West University's Vaal Campus, Nelson Mandela Metropolitan University's Port Elizabeth Campus, and the Vaal University of Technology.

Kovsies are the current Varsity Sevens Champions after winning the title in Cape Town in April 2015.

Ten Kovsie swimmers took part in the USSA Tournament in Johannesburg from 28 November to 30 November 2015. Last year, Kovsies came third, but unfortunately some of their leading swimmers were unable to take part this year.

The Kovsie Table tennis team will participate in the USSA Tournament in Kimberley from 30 November to 4 December 2015.

Most of the USSA Tournaments in the other sporting codes were either postponed or cancelled because of the recent nationwide student protests. As a result of the protests, exams were written later, and tournaments would have taken place during the holidays.

Only the tennis, table tennis, Sevens rugby, swimming, and cricket B Division in East London will continue.

The USSA Soccer Tournament, to take place at the UFS and the Central University of Technology in Bloemfontein, was postponed until March 2016.
