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.

Sisulu Calls for Mugabe to go
2008-08-08

 

Human rights activist and renowned author, Ms Elinor Sisulu, has called on the president of Zimbabwe, Robert Mugabe, to step down.

Ms Sisulu made this call during her presentation of the Women’s Day lecture, titled: “Voiceless and voteless, fleeing zanuphobia into xenophobia: A Zimbabwean woman’s perspective of National Women’s Day” at the University of the Free State (UFS) on Wednesday.

She said thousands of Zimbabweans who fled their country because of violence will not return home unless Mugabe steps down.

“For the Zimbabweans in diaspora, what Mugabe symbolizes is so powerful that as long as he is there as a ceremonial president they will not return home. So the simple message from the South African office of the Crisis in Zimbabwe Coalition is that Mugabe must go”, she said.

She also lambasted the southern African region generally, and South Africa in particular, for its silence over what she calls “Zanu-PF orchestrated violence” that triggered the current refugee influx in the region.

“The South African government was totally silent on the loss of life of innocent and vulnerable Zimbabweans. The mediator said nothing about it”, she said in a clear reference to president Thabo Mbeki, the SADC-appointed mediator.

She said for the Zimbabweans who had to flee to South Africa it was a case of “jumping from the frying pan into the fire”, fleeing Zanuphobia to xenophobia”.

She, however, appealed to the South Africans to raise their voices about the refugee problem that is not only besetting this country, but the whole region.

Ms Sisulu was born in Zimbabwe and she works in the South African office for the Crisis in Zimbabwe Coalition, the major umbrella body of Zimbabwean non-gobernmental organizations.
