Peet Jacobs.

Peet Jacobs is no stranger to the Deaf community in and around the UFS and Bloemfontein. He has been working at the University of the Free State (UFS) for the past six years, and he is still amazed at the amount of support our institution provides to Deaf students in particular, and to South African Sign Language (SASL) in general. “They provide excellent interpreting services,” Peet says, “not only in face-to-face classes, but also on different online platforms, as well as interpreting pre-recorded lectures and videos.” And as a SASL interpreter, Peet is an integral part of this service. 

But signing is not merely a day job for Peet. He carries his skill into the community in his spare time, where he assists as an interpreter at hospitals, doctors’ rooms, and psychiatrists’ offices – to name but a few. What gives Peet the deepest satisfaction, however, is when he can combine his love of Sign Language with his love of the Bible and his God. It was actually Peet’s devotion to his religion that inspired him to learn Sign Language in order to enable him to carry the Word of God into the Deaf community. Peet now also presents Bible courses in SASL and assists a non-profit organisation to produce SASL Bible-based publications, which are translated and recorded in video format. 

Peet aspires to become an authority on SASL subject-specific vocabulary related to subject in higher education. “Sign Language is a language in its own right,” Peet points out. “The uniqueness of Deaf culture and the variety of dialects within SASL give the language diversity and colour.” Peet goes on to emphasise how important it is that SASL is recognised as an official language in our country. “This recognition will give dignity to a group of people who have been marginalised in South Africa. This will also pave the way to providing more inclusivity and service to the Deaf community.”

Until then, Peet will continue to serve the best way he knows how: through signing.

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.
