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.

Reclassification of giraffe status pivotal in public action, says UFS researcher

Great news for those who care about the conservation of giraffes is today’s (8 December 2016) announcement by the International Union for the Conservation of Nature (IUCN) that giraffes are now classified as ‘Vulnerable’. The species, formerly classified as ‘Least Concern’ on the IUCN Red List — an index on the likelihood of extinction of animals worldwide — is threatened with extinction.

“Until recently, few people were aware of the situation facing giraffes. It is time to show the world giraffe numbers are in danger. This reclassification by the IUCN is pivotal to get the public to stand up and take action for giraffes,” said Dr Francois Deacon, specialised researcher in the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State (UFS).

Research is essential to develop effective conservation plans for a species

Key to this announcement was the status report submitted by Dr Deacon. He was the lead author responsible for the submission of the Southern African Giraffe subspecies (Giraffa camelopardalis giraffa) status report that was part of the larger species report submitted for review by the (IUCN). The UFS has been doing many research projects in the past couple of years on giraffe-related issues and topics to address this problem.

The UFS is one of only a few universities in Africa that is committed to studying giraffes to ensure the conservation of this species for generations to come.

“The reclassification of giraffes to ‘Vulnerable’
status, by the IUCN, is pivotal to get the public
to stand up and take action for giraffes.”

A 40% decline in the giraffe population over the past two decades is proof that the longnecks are officially in trouble. According to Dr Deacon, this rate of decline is faster than that of the elephant or rhino. The main reasons for the devastating decline are habitat loss, civil unrest and illegal hunting.

Dr Deacon, pioneer in the use of GPS technology to study giraffes and their natural habitat, said “This vulnerability clearly stipulates we are quickly losing grip on our last few natural populations”. He and a team of researchers at the UFS in South Africa are leading various research and conservation projects to help save the last remaining giraffes in Africa.

Giraffes moved from ‘least concern’ to ‘vulnerable’ on the Red List

The IUCN, a health check for our planet, is the highest level at which decision-makers can prove how many species (fauna or flora) are surviving or not. The update from ‘Least Concern’ to ‘Vulnerable’ on the Red List was released at the 13th Conference of the Parties to the Convention on Biological Diversity in Cancun, Mexico.

A wildlife documentary, Last of the Longnecks clearly shows how the number of giraffes has plummeted in the past two decades from 154 000 to fewer than 98 000 today — with numbers of some giraffes, such as Kenya’s reticulated giraffe, declining by as much as 80%.
