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 Digital Doorway project will change lives in Heidedal

The combined effort of ICTISE (ICT Innovation in School Education), Reach and the Heidedal community saw a four-station Digital Doorway (computer system) being placed on the premises of Reach at the end of 2010. ICTISE is a programme of the University of the Free State (UFS) and operates from the university’s South Campus. This computer system will allow all Heidedal schools and community members to have free access to computers.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, opened the Digital Doorway by cutting a ceremonial ribbon with the assistance of one of the community’s learners.

The Digital Doorway concept originates from a joint initiative between the Department of Science and Technology and the Meraka Institute of the Council for Scientific and Industrial Research. The Digital Doorway consists of four screens and allows access to select content, including open-source application software. This includes audio books, subject textbooks, encyclopaedia, educational games such as “touch maths” and quizzes as well as useful information for school subjects and a newspaper especially for children.

The Heidedal Digital Doorway is the first of its kind in the Motheo District. Typically, one or two kids will be working on each of the computers, while up to five other learners will be giving instructions, allowing the whole group to learn. The Digital Doorway is a smart way of bridging the digital divide, bringing science and technology to our community and opening the doors of learning. ICTISE will support the Heidedal schools to make full use of this new facility by training teachers and community members.

“The UFS hopes that this project will change the lives of the Heidedal community by providing the youth with an opportunity to be in line with the changing world of technology,” said Ms Sarietjie Musgrave, Head: ICTISE.
