Prof Chris Hermans
Prof Chris Hermans, extraordinary professor at the UFS, presents his inaugural lecture, titled Theology in an Age of Contingency.
“The road ahead is empty / It’s paved with miles of the unknown.”

Prof Chris Hermans quoted these lines from the song The Road Ahead, by Dutch vocal group City to City to introduce his inaugural lecture in the Faculty of Theology and Religion on 27 February 2019. Prof Hermans, a veteran researcher in pastoral theology, empirical, and practical religious studies at the Radboud University Nijmegen in the Netherlands and an extraordinary professor at the UFS, chose as his theme Theology in the Age of Contingency, stating that the uncertainty of life has affected all disciplines in the academy, from the sciences, philosophy, and pedagogy, to theology itself.

Although contingency is often defined as a “future event ... which is possible but cannot be predicted with certainty” (Oxford English Dictionary), Prof Hermans stated that, in the context of theology, it has more to do with complexity, unpredictability, coexistence of cultures, and an increasing number of decisions people need to make in modern-day life. 

Changing lanes

Prof Hermans recounted a memory from his childhood to illustrate some aspects of contingency: “Growing up, my parents told me to cycle on the right side of the road. They knew what the right side was. Everything had a right side: What norms and values to live by, what was right or wrong, when to pray and which words to use. ... We now live in a different world.”

Prof Hermans’ inaugural lecture reflected on four tasks of practical theology and missiology. He further asserted that the content and aim of these tasks change from the perspective of contingency.

Contingency perspectives

From a sociological perspective, said Prof Hermans, contingency is a characteristic of the age of modernisation in which we live. He stated that in the modern age, people have a much greater choice of individual ‘action options’ as well as a growing number of experiences as a result. Expounding on this, he said, “The fact that I am a Christian, and another person Hindu or Muslim, is largely due to the fact that I was born within a Christian family. The fact that I am Christian is a possibility and an actuality, but not a necessity.”

Prof Hermans also helped listeners to understand other areas in which contingency plays a role, such as the binary logic used when determining modalities of truth, or changing world views and philosophies of being, or even in our ethos, our art of living, and outlook on 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.
