WomenofKovsies Kesa praises the most important woman in her life
Kesa Molotsane, top Kovsies athlete says much of her success is thanks to the amazing backing of her mother Shani.

Most of Kesa Molotsane’s achievements on the athletic track and road can be attributed to the tireless support of her mother, Kesa says.  

“It might sound like a cliché, but my mother has taught me so much and I have learnt enough from her to survive anything. She has played the biggest role in my career and made it a priority in her life even before it (her athletics career) blossomed. 

‘My mother invested in me’

“My mother Shani has invested so much. She was present at the start and to this day she is still there for me,” Kesa says about the most important woman in her life.

Molotsane, who is doing her BA honours at the University of the Free State, has had a good 12 months behind her. She is the Spar Grand Prix 10km champion from last year, is the national student champion in the 5 000m and 10 000m and was the best South African performer at the Confederation of African Athletics African Cross Country Championships.

‘Improvement and growth motivates me’

She says improvement and growth motivates her big time. “It’s a way of weighing my efforts and hard work. I am inspired by a lot of things, depending on what situation I am in and the inspiration I’m looking for. I believe in and value inspiration in abundance.”

According to her, representing her country at the World Cross Country Championships in Uganda in March 2017 was the biggest accomplishment of her career. “It was my first time at world championships and I was the first South African to cross the finish line. I want to leave my legacy for years to come and want to touch lives using my God-given talent and gift.”

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.
