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.

Ensuring justice does not get lost in translation

The University of the Free State (UFS) is a taking a leading role in changing the face and character of the South African court system, infusing it with qualified professionals.

The university’s Unit for Language Facilitation and Empowerment partnered with the Department of Justice and Constitutional Development as well as the Safety and Security Sector Education and Training Authority (SASSETA). This union lead to 63 court interpreters successfully completing a legal interpreting learnership.

These newly-qualified interpreters will from now on render specialised interpreting services in courts across our country.

Addressing the audience at the diploma ceremony held on the Bloemfontein Campus, Dr Derek Swemmer, Registrar of the UFS, said translators have an important role to play. ”Translation is a gift to those who do not understand the language that a person is speaking,” he said.

In her speech, Nonkululeko Sindane, Director-General in the Department of Justice and Constitutional Development, said the qualification will improve the professional status of court interpreting. She added that the learnership is based on a broader government policy on skills development. She mentioned that eight of those who received qualifications have been permanently employed by the department.

Praising the university for its role, Abbey Witbooi, Chairperson of the SASSETA board, said the diploma will allow qualified learners to contribute to social and economic transformation. This will ensure the protection of human rights in the court setting. In addition, it also provides equal access to a fair trial in terms of effective communication. “The fact that this is a first in the republic, speaks volumes for the extent of the commitment of collective leadership to realise the transformation agenda,” he said.
