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.

Successful conviction on edible oil adulteration
2009-03-28

A successful conviction in the South African food industry for selling diluted olive oil under the guise of virgin olive oil was handed down in the Special Commercial Crimes Court in Durban this week.

Salvatore Pollizi, owner of the company Ital Distributors, pleaded guilty in terms of Section 105A of the Crime Prosecuting Act to selling fake virgin olive oil under the names of Antico Frantoio and Ulivo.

He was sentenced to a fine of R250 000 or three years’ imprisonment, of which R130 000 or 18 months imprisonment is suspended for five years, on condition that he is not found guilty of fraud or theft or an attempt to commit such crimes during the period of suspension.

The offence was committed in 2001 when the scandal involving olive oil being mixed with a cheaper edible oil and being sold as the more expensive virgin olive oil was uncovered by scientists from the University of the Free State (UFS) in Bloemfontein, in collaboration with Mr Guido Costas, The Olive Growers’ Association, AgriInspec and the South African Police Services.

According to Prof. Lodewyk Kock, Head of the South African Fryer Oil Initiative (SAFOI) that is based at the UFS, the conviction is to his knowledge the first successful conviction of this kind in the South African food industry.

Prof. Kock said, “The court’s decision on Monday, 23 March 2009 is good news to our country and sends out a dire warning to all fraudsters in the food industry.”

He attributed the successful conviction to the active and enthusiastic participation by Advocate Joanna Bromley-Gans from the Special Commercial Crime Unit (SCCU) in Durban, Captain Pragasen Govender from the Serious Economic Offences Unit (SEOU) in Pretoria and the team from SAFOI.

Prof. Kock said that in 2003 some of the prominent members of the edible oil industry took responsibility for the authenticity of their own oils by appointing outside laboratories for routine monitoring.

In some cases a seal of approval from such laboratories is displayed on the monitored oil containers. This is an attempt to inform oil distributors, shop buyers and consumers that these oils have been monitored by an outside laboratory for authenticity.

This “policing” has been supported by major role players in the fast-food sector like Nando’s, Spur, Captain Dorego’s, King Pie Holdings, etc. and various oil distributors like Felda Bridge Africa, Willowton Oil & Cake Mills, Refill Oils, etc.
