A packed Odeion Auditorium at the University of the Free State was welcomed by Professor Helena van Zyl, Head of the UFS Business School. The reason being, a panel discussion with award-winning investigative reporter and author, Pieter-Louis Myburgh, on his much-publicised book Gangster State: Unravelling Ace Magashule's Web of Capture. The programme took the form of a panel discussion. The panellists included Pieter-Louis Myburgh, author; Jacques van Wyk from the Association of Certified Fraud Examiners (ACFE); Cathy Dlodlo, news editor from OFM; Alta Vermeulen from the UFS Department of Political Studies and Governance; and Pieter Roux from the UFS Business School.

In his introduction, Myburgh said he was happy that he was able to come to Bloemfontein and have the discussion, since South Africans should cherish freedom of speech and a free press.

The research for the book took 13 months to conclude, and during this time he spent a lot of time in the Free State and Bloemfontein. He mentioned that the book gave him the opportunity to present a condensed account of what he discovered; he could therefore share more, as opposed to just reporting on a story in the newspaper. For him, investigative reporting should always be fact based and open to scrutiny.

Some of the topics raised by the panel was concern about the perception that investigative journalists are focusing more on corruption in the public sector and less on the private sector. This was, however, discarded as a myth, as Myburgh pointed out that he exposed both private and public sector dealings in order to provide the full scope of involved parties.

Focusing on whistle blowers, the panel challenged the verification of whistle-blower information. Myburgh responded that journalists never use only one whistle-blower’s evidence, since that is merely the start of the investigation. Further investigation was necessary, and facts had to be verified. With that said, there is still a lot to be done with regard to the protection of whistle-blowers, he concluded.

The floor was opened to the audience, which provided the opportunity to ask questions and raise concerns about what was mentioned during the panel discussion. The audience eagerly participated in the discussion. In conclusion, Myburgh reiterated that society plays a vital role in keeping those in power to the promises they make.

After the discussion, the audience had the opportunity to have their books signed by the author.

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.
