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.

Excellence in Teaching and Learning is highly regarded at the University of the Free State, with our academics recognised on national and international platform.

Earning yet another accolade for the university, Dr Philemon Akach, Head of the Department of South African Sign Language, has been awarded a National Excellence in Teaching and Learning Award. The award by the Higher Education Learning and Teaching Association of Southern Africa (HELTASA) and Council on Higher Education (CHE), recognised Dr Akach as a “leader in the field of teaching and learning – with impact beyond the classroom and the institution.” Recognising his pioneering work within deaf education, HELTASA and CHE commend Dr Akach as an “inspirational practitioner who recognises the inclusion of the marginalised in education.”

Dr Akach is one of five recipients, selected out of a total of 22 candidates from across South Africa that will receive the award. The other winners are from the University of Cape Town, Stellenbosch University, University of KwaZulu-Natal and the University of Pretoria. The five winners will receive the awards at a gala dinner at the annual HELTASA conference, which takes place from 26 to 29 November 2013.

Dr Akach, who will retire at the end of 2014, says the national recognition is the cherry on top as he prepares to return to his home country. Kenya. “How good can it be?” “This is my life calling,” he said about the 37 years he worked within deaf education.

The academic also received an Alumni Award for Outstanding Service at the recent Kovsie Alumni Awards.

Pioneering work by Dr Akach:

  • With Dr Akach steering the process, the UFS became the first university on the continent to offer Sign Language as an academic course in 1999.
  • Dr Akach was part of a nine-member task team that handed over the South African Sign Language (SASL) curriculum to the Minister of Basic Education, Angie Motshekga. A member of the ministerial task team since 2009, he helped to coordinate the development of the curriculum that will soon be offered as a school subject to Grade 0–12 learners in all 42 schools for the deaf in South Africa.
