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 opens centenary complex
2004-10-12

Today, 12 October 2004, the University of the Free State (UFS) opens the Centenary complex on the grounds of the old Reitz dining hall.

Me Edma Pelzer, Director: Physical Resources and Special Projects at the UFS, said the Centenary complex is furnished mainly for personnel and alumni, just as the Thakaneng Bridge was primarily established as gathering place for students.

On 10 March 2004 the UFS management held the first official function in the half completed complex during the unveiling of the memorial stone by the Rector, Prof Frederick Fourie. What made this occasion remarkable is that old President FW Reitz, 81 years earlier, on 10 March 1923, also laid a memorial stone at the same place, said Ms Pelzer. The complex originally existed of the Reitz dining hall, which was named after old president Reitz, a hostel father residence and administration offices. In historical documents about old president Reitz it is mentioned that already as chief judge he campaigned for the establishment of a university in the Free State and later as president he proceeded with this attempt.

With the opening of the Thakaneng-bridge food preparation and -serving at the Reitz dining hall was discontinued. The kitchen and dining facilities became obsolete. With the evacuation of the old student centre replacements for the Bloemfontein- and Anlgo American-rooms were to be found elsewhere on campus. The idea to convert the historical Reitz building complex in an UFS reception and a space for socialising started to exist.

Ms Pelzer said the UFS is committed to treat its history and its old buildings with respect and to utilise it optimally to enhance the strategic objectives of the university. The Centenary complex must communicate the university as an established, quality institution with an interesting history to visitors. It must serve as a home for alumni and as a one stop visiting point for important visitors who do not have time to experience the whole campus.

In the complex provision is made for entertaining and kitchen facilities, a museum where valuable UFS-memorabilia are kept and exhibited, an amfi theatre and an art gallery which would for the first time offer a permanent home for the art collection of the UFS. Venues will accommodate groups from between 15 to 300 persons.

The reception area will be used by the UFS for occasions such as chancellors’ functions, smaller and bigger receptions for the rector, tea parties after graduation ceremonies, openings of conferences and long service awards. The university also plans to rent out the complex for prestige occasions where the UFS personnel and alumni are involved.

The opening of the Centenary complex form part of the Centenary celebrations of this week. Many of this week’s activities will take place in the complex.
