“Have we — have I — thought sufficiently about the deeper and sacred meaning of everyday life?” Intriguingly, this was how Prof Jan-Albert van den Berg concluded his inaugural lecture on 28 March 2019. During this journey, Prof Van den Berg took his listeners via the scenic route, starting with a mere outline of the divine — first a sketch, then a drawing, until a fully-fledged painting emerges — ending with a manifestation of glory as seen by each individual.

Faith in popular culture

“Practical theology,” said Prof Van den Berg, “implies a specific sensitivity and feeling for the description and meaning of practice and praxis. The use of narratives is one possible way of understanding and documenting a specific involvement in praxis.”

As an object lesson from popular culture, Prof Van den Berg cited the now-infamous-yet-ultimately-beneficial amateur restoration of the Ecce Homo by octogenarian Cecilia Giménez in Borja, Spain. The original fresco, ‘Behold the Man’, was painted in 1930 by Spaniard Elías García Martínez. By 2012, the artwork had suffered the ravages of time, until Giménez’s enthusiasm for art restoration happened to it. At first, the historical society and local townsfolk were up in arms. However, since 2012, Borja’s flagging tourist industry has been revived, and the proceeds from the picture’s fame help to fund not only a local museum but a care home for the elderly as well. 

The entire debacle quickly went viral on social media and the internet, leading Prof Van den Berg to comment on the underlying significance of social media as a field of praxis. As a nod to this aspect of modern culture, he specifically used hashtags (#sketching, #drawing, #painting, #tweetingGod, #findingthesacred) for the subtitles of his lecture. He said, “This is how the Twitter world in particular talks about God, in order to express multiple and compound understandings of daily life.” 

Evergreen Bible student

Prof Van den Berg’s love of practical theology dated back to his days as a student, when he said he learnt that “theology was not just a noun but a verb”. He said: “Practical theology’s description of the Divine in everyday life represents, for me, the relevance and topicality with which I associate theology.” He added that the title of his inaugural lecture directly relates to this understanding, as much as it can be strongly associated with his recent doctoral thesis at the University of Queensland, entitled Tweeting God: A practical theological analysis of the communication of Christian motifs on Twitter.

Expressions of faith in the mundane

In answering his question, mentioned at the outset, Prof Van den Berg said: “Perhaps there is more to be seen, heard, and read in everyday-life texts of the Cecilias of the world who take up their ‘paintbrushes’ ”. Stating that formal theological language has, in certain aspects, lost some of its impact and that many people have turned a deaf ear to the articulation of these truths, Prof Van den Berg concluded that “one must envision possible alternative descriptions, in the form of existing practices of #tweetingGod, finding the sacred in everyday life”.

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
