USSA hockey – lots to play for

The Kovsie men’s and women’s hockey teams have positive expectations for the University Sport South Africa (USSA) national student tournament.

The USSA championships were hosted by the University of the Free State (UFS) from 2 to 6 July 2018. This year’s championships will have 45 competing teams and will thus be the biggest ever USSA hockey tournament.

For the female squad to qualify for the 2019 Varsity Sports tournament, they have to secure a spot among the top-seven teams. In order to get back into the A section, the Kovsie men’s team must win their tournament. 

The matches are scheduled to take place on the UFS Bloemfontein Campus astro fields.

The UFS women’s team, captained by Antonet Louw, is set to play on Monday at 15:35 against Nelson Mandela University (NMU); on Tuesday at 17:00 against the University of Johannesburg (UJ); and on Wednesday at 18:25 against North-West University (NWU). The play-off matches will take place on Wednesday, Thursday, and Friday.

The men’s team, with Cheslyn Neethling as captain, will play on Monday at 17:00 against the Central University of Technology; on Tuesday at 15:35 against the Tswane University of Technology; on Wednesday at 17:00 against the Vaal University of Technology; on Thursday at 18:25 against the University of KwaZulu-Natal; and on Friday at 15:35 against Rhodes University.

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.
