“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”.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
