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.

Public Protector visited Faculty of Law
2005-09-23

On 21 September 2005 the Public Protector visited the Faculty of Law.  This event took place at 10:00 in the Senate Hall of the CR Swart Building, after which a light lunch was served for the delegates and staff of the Faculty.

The purpose of the visit was to spell out the roles, functions and powers of the Public Protector, to promote public awareness and transparency and to increase contact between the Faculty and the Public Protector.  Sufficient time was allowed to answer all the questions posed by various parties, and brochures were made available.

All law students and staff members of the Faculty were invited to the occasion.  The presentations also included information regarding career possibilities for students with the Public Protector’s office.  This organization is more than willing to involve students in community service projects and would keep in contact with the Faculty in this regard.

All the representatives of the Public Protector’s office who visited the Faculty are in the law profession:

The following persons made presentations:

Mr P Nthotso:  Independent Complaints Directorate
Ms L Mdalane: Directorate of Special Operations – Scorpions
Ms M Thetlhu: South African Human Rights Commission
Mr A Madiba:  Office of the Public Protector.

The persons mentioned above were accompanied by their supervisors, viz. Mr L Mashee (Head Public Awareness, Free State) and Ms SD Griessel (Provincial representative for the Public Protector, Free State).  A further two employees of the Public Protector attended as observers, viz. Mr T Kgabeginyane and Mr MR Matlesoane.

The Public Protector functions independently and reports directly to Parliament.

Staff and students found the visit very informative and valuable contacts were made in the process.
