Experts engage in stimulating discussion on South Africa future
Moeletsi Mbeki, Prof Phillippe Burger, Dr Ina Gouws, and Waldimar Pelser.

The University of the Free State (UFS) and the broader Bloemfontein community had the privilege of listening to expert opinions on the country’s future at the Wynand Mouton Theatre on the Bloemfontein Campus on 2 March 2018. On stage were Waldimar Pelser, Rapport editor; Prof Phillippe Burger (Department of Economics); Dr Ina Gouws (Department of Political Studies and Governance) from UFS; and author and businessman Moeletsi Mbeki. Together they painted a critical picture of our current and future state of affairs during a remarkable morning hosted by Rapport Regstreeks and kykNET. 

The ills of our economy
Master of his subject, Prof Burger had the audience spellbound when he explained the real issues surrounding our current sluggish economy. He was concerned about the general lack of growth – the major reason for unemployment. Figures have shown that even a slight increase in economic growth, creates an increase in employment. “We know that good education leads to economic growth,” he said. Poor education is one of our big problems, with our school mathematics performance among the worst in the world. He further advised that we should roll back patronage, stabilise public debt, facilitate a true partnership between government and businesses, identify specific growth sectors, address tenure rights, develop supply chains, and develop special skills. “I believe that we should bring back apprenticeships,” he said. 

Political pains
Mostly in agreement with Prof Burger’s contribution, Mbeki wanted to add politics in the mix as a factor that harms our economy. Capturing the audience with his impressive knowledge and insight, he explained that we basically still sat with the British economic systems set out between 1902 and 1910 – the production and export of minerals, fuelled by cheap labour. The mining sector provided a market for agriculture that also used cheap labour. Currently, we sit with two elites: the capital elite that produces, and the political elite that taxes the profits. Hence, the money is not reinvested. “We need new elite, that will invest in the country, instead of consuming the profits,” he said. Who should this be? “Such a coalition must include owners of productive assets who should form an alliance with rural people.”

Remain vigilant
Dr Ina Gouws supported this notion, saying that now was not the time to put our hopes in one leader for a better future. We should remain critical and vocal about our concerns. Political leaders did not always paint a true picture of what the people wanted and felt. 

More interesting and current topics were addressed during the question and answer session, and Pelser ensured that all adhered to a strict schedule, while using the available time optimally. We hope to see more such events on campus, inviting discourse on current topics.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
