Physics excels in Afrikaans Academy for Science and Art symposium
UFS postgraduate students in the Department of Physics attended the Student Symposium of the Afrikaans Academy for Science and Art. From the left are Izak van der Westhuizen (PhD) and Hélène Szegedi (MSc), who both came in second place in their respective sessions. On the right of the banner are Dina Oosthuizen (PhD) and Lucas Erasmus (MSc),who claimed first place in their respective sessions.

Every year postgraduate students from all universities and universities of technology in the country are invited to participate in the student symposium of the Afrikaans Academy for Science and Art.

Honours, master's, and doctoral students from different universities in different scientific fields, including chemistry, physics, computer science, engineering, geography, medicine, etc. participated in the symposium. From the Department of Physics at the University of the Free State (UFS), Dina Oosthuizen (PhD) won a first prize in session 1, Hélène Szegedi (MSc) won second prize in session 2, where Lucas Erasmus (MSc) claimed first place and Izak van der Westhuizen (PhD) took second place in session 3.

'We love what we do'

Students from the UFS do incredibly well each year at this symposium. “These achievements speak of the excellent education and training we receive, especially in the department. Physics students not only have lecturers and supervisors who are well-respected in their own research fields but have access to world-class instruments in our physics laboratories. We also love what we do and see it as a privilege to share our work.

“The symposium is also an opportunity to gain valuable experience in presenting our own research as well as getting exposure to various research topics, methods and scientific disciplines,” said Hélène Szegedi, who is a junior lecturer in the Department of Physics

Symposium unique on many levels



Although every participant has to present in Afrikaans, it is not only Afrikaans-speaking students who participate in the symposium. Szegedi said: “The language requirement for the symposium does, however, create the opportunity to develop Afrikaans further as a science language, and we sometimes have to coin new words or terms to describe our research, making this symposium unique and beneficial on many levels.”

Renowned forensic scientist speaks at the UFS

It is necessary for more research to be done in the field of forensic science in South Africa. This is according to Dr David Klatzow, well-known forensic scientist, during a lecture delivered at the University of the Free State (UFS) last week.

The university is offering, for the first time this year, a BSc degree in Forensic Science in the Department of Genetics. This three-year degree is, among others, directed at people working for the South African Police Service on crime scenes and on criminal cases in forensic laboratories. Students can also study up to PhD level, specialising in various forensic fields.

There is no accredited forensic laboratory in South Africa. “It is time to look differently at forensic science, and to deliver research papers on the subject. In light of the manner in which science is applied, we have to look differently at everything,” Dr Klatzow said.

Dr Klatzow praised the university for its chemistry-based course. “Chemistry is a strong basis for forensic science,” he said.

A paradigm shift in terms of forensic science is needed. Micro scratches on bullets, fingerprints, DNA, bite marks – all of these are forensic evidence that in the past led to people being wrongfully hanged. This evidence is not necessarily the alpha and omega of forensic science today. DNA, which seems to be the golden rule, can produce problems in itself. Because a person leaves DNA in his fingerprint, it is possible that DNA is transferred from one crime scene to another by forensic experts dusting for fingerprints. According to Dr Klatzow, this is only one of the problems that could be experienced with DNA evidence.

“No single set of forensic evidence is 100% effective or without problems. Rather approach the crime scene through a combination of evidence, by collecting fingerprints, DNA, etc. It is also very important to look at the context in which the events happened.

“A person sees what he expects to see. This causes huge problems in terms of forensic science. For example, if a criminal fits the profile of the perpetrator, it doesn’t follow that this specific criminal is the culprit. It isn’t what we don’t know that gives us trouble, it’s what we know that isn’t so,” Dr Klatzow said.
