Prof Johan Meyer, Senior Professor in the Department of Mathematics and Applied Mathematics, says he is looking forward to learning from others in the field during this collaboration.

What do trees, black holes, earthquakes, and time structures have in common? 

The answer to this question is that these, in one way or the other, form the focus of some of the abstracts delivered during the Annual Congress of the South African Mathematical Society. The society has as its main objective the advancement of mathematics in South Africa. 

The Department of Mathematics and Applied Mathematics at the University of the Free State (UFS), in conjunction with the South African Mathematical Society (SAMS 2021), is hosting the 64th Annual Congress of the society this week (29 November to 1 December 2021).

Prof Johan Meyer, Senior Professor in the department, says the congress, which is being conducted online, is focusing on all aspects of mathematics research, including history and teaching.

Learning from others in the field

The congress, which aims to share the latest research results in mathematics, will be attended by staff and students from universities across South Africa as well as abroad. “Anyone from the public is, of course, welcome to attend or even share their results if they are also involved in mathematics research,” adds Prof Meyer. 

He says that he is looking forward to learning from others in the field during this collaboration. 

The congress will include discussions on more than 120 abstracts, covering category theory, algebra, topology, logic; functional analysis and operator theory; finite groups and combinatorial structures; graph theory and combinatorics; lie symmetries and nonlinear differential equations; and applied and numerical mathematics.

Array of interesting topics presented

“It is important in many areas of science and engineering to predict and to simulate rare, random events, the occurrence of which may have negative or even catastrophic consequences. Examples include internet server overflows, mechanical breakdowns, floods, and financial crashes. Rare events can also have a positive effect, triggering for example chemical reactions or driving genetic evolution via random mutations.” Prof Hugo Touchette from Stellenbosch University will be shedding some light on this interesting topic in his presentation on Predicting and simulating rare events.

Prof Jeandrew Brink, Associate Professor in the Department of Mathematics and Applied Mathematics at the UFS, is presenting a plenary session on the topic Determining the geometry of strong field space-times in spite of tacitly assuming the answer during every measurement. In South Africa, state-of-the art pulsar timing data from the MeerKAT telescope will make a considerable contribution to conducting GR orbital tests. Prof Brink comments on how pulsar timing tests differ from tests using gravitational wave detectors, as well as what we can learn from the framework already employed to perform pulsar timing measurements.

There’s more to media freedom than the Secrecy Bill
2012-05-04

4 May 2012

 “Media freedom is a universal human right. It cannot be abolished, but it should be managed.” The freedom of the media is protected by numerous formal documents, including the Universal Declaration of Human Rights and the South African Constitution, and is commemorated annually with the celebration of World Press Freedom Day.

 “As long as those in power have something to hide, media freedom will be under threat. This is a war that takes place on many fronts,” says Ms Willemien Marais, a journalism lecturer at the Department of Communication Science at the University of the Free State (UFS).

“On the one hand we have to take a stand against institutional threats such as the proposed Protection of State Information Bill. This is diametrically opposed to everything that media freedom and freedom of expression encapsulates.

“But on the other hand we also need to educate and transform our society. It is not only up to journalists to defend media freedom. Newspaper reports on the public hearings on this Bill earlier this year proved that ignorance concerning media freedom is a big threat. The lack of resistance against the Secrecy Bill from the general population clearly illustrates that people aren’t aware of what they are about to lose.”

 Ms Marais says the rise of social media and the accompanying awareness of individual freedom of expression have paved the way for more people to exercise this right. “The role of social media in the Arab Spring has been highlighted numerous times. The power of social media is undeniable – but alas, so is the lack of access to especially social media. We can only increase media literacy if we increase people’s access to the media – new and traditional.”

A high level of media literacy is also vital following last month’s recommendation by the Press Freedom Commission of a system of independent co-regulation for South Africa’s print media. This system proposes replacing government regulation with a panel consisting of representatives from the print industry as well as members of the general public. “It is abundantly clear that this system can only work if those members of the general public are media literate and understand the role of media freedom in protecting democracy.”

“The media is not a sentient being – it consists of and is run by people, and human beings are fallible. Protecting media freedom does not only mean fighting institutional threats. It also means increasing media literacy by educating people. And it means owning up to your mistakes, and correcting it.”
