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.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
