New member of the Pontifical Academy of Social Sciences - Prof Pearl Sithole

Social scientist and Vice-Principal: Academic and Research on the Qwaqwa Campus, Prof Pearl Sithole, was appointed by Pope Francis as a member of the Pontifical Academy of Social Sciences for her stellar work in social sciences. 
Academicians are appointed by the Pope on the basis of their competencies in the social sciences and their moral integrity.

Prof Sithole said she was looking forward to sharing meaning and impact with the world through a space dedicated to the social sciences. “It’s a great honour. I’m feeling really humbled. The social sciences and humanities are a hugely necessary space to make meaning of the world, but for some reason, in the pecking order, they were relegated to a space that is thought of last. This appointment is to a dedicated space – to say, let’s look at issues through that lens.”
The Pontifical Academy of Social Sciences was established by Pope John Paul II in 1994 with the aim of promoting the study and progress of the social sciences, primarily economics, sociology, law, and political science. To achieve its aims, the academy organises conferences and workshops on specific themes, promotes scientific surveys and research, and publishes publications. 

Prof Sithole said the academy provides a wonderful way of reminding academicians of the importance of relating science to the real world. 

“What I like about it is that it demystifies science. It says, be excellent in your field but be able to converse for impact, be able to come to a forum that worries about specific issues, it still encourages publications and pure science/scientific endeavours, advancements in their field, but sometimes people come together to look at an issue from various angles. For me, it’s such a wonderful way of saying we must remember that we are doing science in order to relate to the world, not just to understand for the sake of understanding,” she said.

Make a genuine effort to make a difference in whatever you do, and your work will speak for itself.- Prof Pearl Sithole. 

The appointment also coincides with Women’s Month, and Prof Sithole said she takes great pride in her womanhood. 

“I am a mother and a daughter. I strive to pinpoint problems and offer solutions. I am a social scientist. I’ve made it a mission to study how systems affect people by infusing humanity within the systems. Women have been made to be apologetic about the qualities that define us as women, which we bring especially into leadership. I don’t apologise for my emotions. I don’t apologise for my multitasking abilities; however, I do feel that women are often abused for having these.”

What would you say makes you a UFS woman of quality, impact, and care?

I am the sort of person who strongly believes that your work should speak for itself. I don’t work for accolades. My approach to life is to work genuinely to make a difference, and your work will speak for itself. If you wake up every day to genuinely make a difference, it is enough. You get a lot of satisfaction in life, and you sleep better because you know you have given it your best, and you know that sometimes you can actually see it making a difference.

What advice would you give to the 15-year-old you?

I would say, be true to yourself. At a younger age, you want to chase all sorts of aspirations that look glamorous, which is not a bad thing, because you have to have appetite; but in your appetite for excellence and as someone who lives for a purpose, be true to yourself. Be able to design a life that aspires, but at the same time be adaptable to what you discover your strengths to be.

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.
