Jana Scholtz, goal defender and playing in her first year as a regular starter, has been a solid performer for the Kovsie netball team in Varsity Netball.

The building blocks are starting to form a solid basis from where Kovsies can launch an attack to defend the Varsity Netball title they won in 2018. This is according to Karin Venter, one of the team’s assistant coaches.

After losing their first encounter to Tuks, they registered wins over the University of Johannesburg, Tshwane University of Technology, and the North-West University. The match against the Maties in Bloemfontein on 23 September 2019 – the last in the group stage, should determine which of the two teams will book a home semi-final along with Tuks.

“Yes, that is the crucial one,” said Venter, the team’s defensive coach. Her counterpart at the Maties is Adéle Niemand, with whom Venter combined as defenders at Kovsies for several matches in the mid-2000s. Apart from the Maties, the women of the University of the Free State still have to face the Madibaz and the University of the Western Cape (both in Pretoria on 15 and 16 September 2019).

“The combinations are starting to form a unit and our confidence is on the increase. Now we are looking for consistency in our performances.”

According to Venter, they were hit hard by goalkeeper Ané Retief’s injury, which kept her out of the first two matches. This meant that they had to start against Tuks with a first-year student, Chanel Vrey.

“It was tough, but I’m impressed with the way in which she, Ancia Pienaar, and Jana Scholtz – who are all youngsters – stepped up.”

Venter is responsible for the analyses and recons to assist players.

“The programme we are using provides us with all the required footage. You can make notes on it and send these clips to players, which means you don’t have to sit next to a player to explain something. We also provide them with notes and sketches of opponents’ playing patterns, which they must work through as part of their preparation.”

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.
