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.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
