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.

UFS Centenary ends with a weekend of festivities
2005-02-04

The University of the Free State ’s (UFS) Centenary celebrations will come to an end this weekend with a packed programme.

“We celebrated this momentous milestone of the UFS since 28 January 2004 and want to end the year on a high note,” said Mr Jan Ras, Centenary Coordinator.

The weekend will start on Friday 4 February 2005 when Prof Frederick Fourie, Rector and Vice-Chancellor, will open the UFS officially. This will be followed by an historic photo of all staff and students who are on campus that day. All staff will be wearing their academic gowns and the Centenary emblem will be depicted.

The annual Kovsie Engen Rag, with We thank you South Africa as theme, will take place on Saturday 5 February 2005 . The procession will start at 08:00 from the UFS Kovsie church and will move down Nelson Mandela Drive and right into Markgraaff Street exit until it reaches St Andrew’s Street. From here it will turn right into Kings Way where it will stop at the Art Market at 10:00 . Prof Frederick Fourie will then propose a toast on the procession. Afterwards the groups and orchestras will step out and the floats will move through the center of town around Hoffman Square and then back to the UFS campus.

According to Mr Ras a reunion for the Student Representative Council (SRC) will also take place this weekend. About 100 former SRC members are expected to attend the planned activities.

The weekend will be concluded on Sunday 6 February 2005 with a special service of devotion, hosted by all the interdenominational groups on the campus. The service starts at 18:00 for 18:30 in front of the Main Building of the UFS and will be a celebration of praise, thanks and worship, followed by a message from Dr Wollie Grobler. The evening will be concluded with a mass choir and a fireworks display.

“Members of the public are welcome to attend the service of devotion and are requested to bring a candle for the purpose of the mass choir. Although chairs will be arranged in front of the Main Building , people are requested to bring extra pillows and blankets to sit on,” said Mr Ras.
