Siphilangenkosi Dlamini – selected by Inside Education and the NYDA as one of South Africa’s 100 Shining Stars for 2022.

Siphilangenkosi Dlamini, a fourth-year Governance and Political Transformation student at the University of the Free State (UFS), has been selected as one of South Africa’s 100 Shining Stars for 2022 by Inside Education, in partnership with the National Youth Development Agency (NYDA). 

“I was more surprised than anything, but also very honoured,” he said. Dlamini, who made it into the Civil Society and Youth category, was chosen from a pool of 800 applicants for his remarkable work with the Help a Student initiative, and his services as the former secretary of the Southern Africa Scout Youth Forum. Although he could not attend the award ceremony held in Johannesburg on 20 October 2022 in person, Dlamini did receive a certificate. “What we do a lot of the time isn’t for recognition and it’s not necessarily for awards; but getting recognised motivates and assures me that the work we are doing has an impact,” he expressed.

The Help a Student Initiative

In the early stages of the COVID-19 pandemic, Dlamini recognised a rise in food insecurity among his fellow students. This set him on a path to source funding for the establishment of the project. 

The Help a Student initiative aimed to curb food insecurity through the provision of food parcels to UFS students who were in need. The project, which ran from 2020 until early 2021, managed to distribute food parcels to nearly 250 students per month. The initiative did not only assist students who were on campus. The selected applicants who were at home or off campus also received digital food vouchers, which allowed for the purchasing of food items at Pick n Pay and/or Shoprite.

“Food security is something that I am passionate about. I grew up in a community where it was a massive issue.

However, in the past I was not empowered enough to know how to solve it. Therefore, when the opportunity presented itself to do something about it, I took it with both hands,” Dlamini expressed.

Although the recognition was not expected, Dlamini maintains that such platforms are imperative, as “they demonstrate that young people are doing something to improve the country in the different capacities they are in”.

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

Profile of the gravitational waves of the colliding black holes.

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.
