Prof Johann Rossouw Inaugural lecture

For Prof Johann Rossouw from the Department of Philosophy, the Naval Hill Planetarium – a digital planetarium on a hill in the centre of a modern city, was the perfect place to deliver his inaugural lecture titled, The soul of the academy.

The message of his inaugural lecture was on “the form adopted by the contemporary university, which is so focused on the quantitative that the qualitative is neglected. The focus on training is so strong that the university no longer pays attention to the education of students”.

Prof Rossouw referred to the soul of the academy as the highest in humanity, especially the part which cannot be counted. He also referred to the words of Blaise Pascal in the 17th century: “The heart has its reasons of which reason knows nothing”.

“Do we understand any of this in the contemporary university? And do we still remember the earliest origins from which the academy originated; that Philosophy is the mother discipline of all other disciplines, and how all contemporary disciplines form part of a bigger, coherent entity?” he asked.

The inaugural lecture took place on 28 February 2019. Prof Rossouw has a C2-rating from the National Research Foundation, and it is thanks to him, among other things, that the Department of Philosophy is the only South African Philosophy department with modernity studies as its main focus.

At the end of 2018, he was promoted to Professor of Philosophy at the University of the Free State (UFS), and currently he serves as acting Head of Department. “Due to Prof Rossouw’s involvement, among other things, research on African philosophy, critical theory, postcolonial thinking, and tradition and modernity is conducted in the department,” Prof Heidi Hudson (Dean: the Humanities) said.

Prof Rossouw started his formal training in Philosophy at the age of 12, and in 1991 he obtained a BA degree majoring in Philosophy and Psychology at the University of Pretoria, with distinction. He obtained his MA degree, a critical study of apartheid on the basis of Michel Foucault’s thinking, at Unisa in 1998. In 2002, he obtained his DEA in Philosophy at the University of Lyon 3 under the leadership of Régis Debray, and in 2013 his PHD on the theological trail in Bernard Stiegler’s thinking at Monsh University (Melbourne), under Michael Janover.

In 2016, he won a prize from the South African Academy for Science and Culture for one of the best Afrikaans humanity articles published in 2015.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
