#UFSGraduation: Young lecturer wants to teach about the power of mathematics

Mathematics is undeniably part of the world – from telling time, buying groceries, to manufacturing clothing sizes, and everything in between.

This is the view of Corlé van der Walt, Junior Lecturer in the Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), who received her honours degree in mathematics and applied mathematics (with distinction) at the university’s April 2023 graduation ceremonies.

The focus of her honours was on applied mathematics, specifically optimisation and dynamical systems. “These subjects link to my undergraduate degree, which is in industrial engineering,” says Van der Walt, who has always enjoyed and excelled in mathematics for as long as she can remember.

Maths = skills +

She believes that mathematics is important because it helps us describe and value ourselves. “But still, mathematics is more than just the skills we learn; in the words of Albert Einstein, "Mathematics is, in its way, the poetry of logical ideas".

She says that mathematics is also the foundation for other sciences, such as physics, chemistry, and engineering. “Mathematics paves the way for all other forms of science. Without the computational groundwork, it will not be possible to do physics, chemistry, engineering, or any other form of science,” she adds, remarking that we will not be able to make scientific or technological progress.

“This is where I come in; I want to teach young upcoming students’ mathematics and the power of it. I want to show students that mathematics is not necessarily difficult, but that it is logical and practical. With my current qualification, I have already been appointed as a junior lecturer and I teach precalculus to university students who would like to take calculus,” she says.

A balancing act

Although she enjoys her work, Van der Walt finds it challenging to juggle work and studies. But she overcomes these obstacles by prioritising tasks and celebrating small achievements. Her motivation also comes from the joy of seeing her students understand concepts that they previously struggled with.

With plans to complete her master's degree in the next two years and commencing her PhD studies, Van der Walt is committed to teaching the power of mathematics to upcoming students.

Postdoctoral researcher, Abdon Atangana, of the Institute for Groundwater Studies at the university recently published an article online about the Lassa Haemorrhagic fever in the Natural Computing Applications Forum. In addition to the terminal transmissible sickness recognised as Ebola haemorrhagic fever, there is another strain called Lassa haemorrhagic fever.

The disease is classified under the arenaviridae virus family. The first outbreaks of the disease were observed in Nigeria, Liberia, Sierra Leone, and the Central African Republic. However, it was first described in 1969 in the town of Lassa, in Borno State, Nigeria.

The main host of the Lassa virus is the Natal Mulimammate mouse, an animal indigenous to most of Sub-Saharan Africa. The contamination in humans characteristically takes place through exposure to animal excrement through the respiratory or gastrointestinal tracts.

Mouthfuls of air containing tiny particle of infective material are understood to be the most noteworthy way of exposure. It is also possible to acquire the infection through broken skin or mucous membranes that are directly exposed to the infective material.

“The aim of my research was to propose a novel mathematical equation used to describe the spread of the illness amongst pregnant women in West Africa. To achieve this, I used my newly-proposed derivative with fractional order called beta-derivative. Since none of the commonly used integral transform could be used to derive the solution of the proposed model, I proposed a new integral transform called Atangana-Transform, and used it, together with some iterative technique, to derive the solution of the model.

“My numerical simulations show that the disease is as deadly amongst pregnant women as Ebola,” Abdon said.

Abdon’s research was submitted to one of Springer’s top-tier journals with an impact factor 1.78. The paper was accepted and published February 2015.
