Dr Martin Mandew believes that the devastating impact of the pandemic will be felt for quite some time.

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 August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
