It is not easy to discern the silver in the lining of the pandemic cloud that we have been living under over the past twelve months. I hazard to say that for those at the bottom of the socio-economic heap, those whose daily life is nothing but a gut-wrenching struggle to scrape together a semblance of a meal, talk of silver linings is foreign to their experience. The pandemic has shown just how low leaders can sink when elected public officials steal and redirect food parcels – meant for the poor and destitute – for their own personal consumption, for those close to them through family ties, through friendship and through political affiliation, or sell it for personal financial gain. The intended relief measures, designed to be non-partisan, are used instead to promote the socio-political divisions that already exist in the community. The unspoken mantra seems to be: If you look like me, if you think like me, if you believe like me, if you speak like me, if your political beliefs are like mine, only then can you expect me to do the public good for you and for your benefit that I have been elected to do, even though I get paid for carrying out this very important task. Talk of unity is rich in such an environment.

Nation-building
The devastating impact of the pandemic will be felt for quite some time. In the next twelve months we must, despite the enormous challenges ahead, re-imagine and craft a future of unity, where personal, political, ethnic, racial, gender, economic, and other differences will not stunt and sabotage efforts of socio-economic renewal. This Human Rights Month is a stark reminder for us to go back to our foundations as a South African nation. It is a time to press the reset button in the agenda of nation-building. Nation-building is not achieved through a fiat, a ‘let-it-be-so’ declaration. While taking the necessary steps to rebuild a battered economy, nation-building also entails making the necessary investments in social support to alleviate the impact of the pandemic on the most vulnerable in society, while also ensuring that the white-collared hyenas are kept at bay. The right to health care, food, water, and social security is enshrined in the Constitution.  

The future
Nation-building also entails making bold investments in education, taking care that as budgets are re-organised, re-prioritised and reduced, the education sector is not made a casualty of austerity measures. We must not falter to build our nation on a solid foundation of education, ensuring that we make the right investments and the required interventions in this very critical sector. There are components in the sector that are weak and glaringly under-resourced, such as early childhood development, as well as post-school technical and artisanal training. We need to strengthen these as part of building a firm foundation for our fledgling nation. This is a very important asurance for the future of our nation. Only an educated nation is best equipped to confront the challenges that lie ahead, such as those that the COVID-19 pandemic has thrust upon us. The right to education is enshrined in the Constitution.

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.
