Corlé van der Walt received her honours degree in mathematics and applied mathematics. She wants to show students that mathematics is not necessarily difficult, but that it is logical and practical.

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.

UFS researchers discover the many uses of the cactus pear

UFS researchers discover the many uses of the cactus pear

For many South Africans, the dry, arid areas in many parts of the country became synonymous with cactus pear growing at random in the natural veld. For some the fruit of a cactus pear, if chilled really well, is a delicious snack on a hot summer’s day. But few actually know that these cacti can be money growing wild in the veld.

For the past 15 years, scientists  at the University of the Free State (UFS) have been looking into the benefits and many uses of the cactus pear. This project  has grown steadily in vision and dimension, and today the UFS is recognised as a world-leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Dr Maryna de Wit, from the Department of Microbial, Biochemical and Food Biotechnology, together with Prof Wijnand Swart from the Department of Plant Sciences and Prof HO de Waal from the Department of Animal, Wildlife and Grassland Sciences, determined the nutritional and, more importantly, the commercial and viable uses of the cactus pear.

The aspect of human consumption is now giving the cactus pear the status of ‘superfood’.

Dr De Wit and her team have successfully made various products using either the cactus pear fruit, the cladode (also referred to as the leaf) and the mucilage (the sticky liquid  in the cladode).

Some of these products are:

  • flour for baking carrot cake, biscuits and health breads
  • jam, fruit juice and canned fruit
  • sweets – marshmallows and Turkish delight
  • stir-fry, salads and other cooked dishes.
