Sikhululekile Luwaca named 100 Young Mandelas of the future
Sikhululekile Luwaca was recently named as one of 100 Young Mandelas of the future by News24 for his embodiment of Nelson Mandela’s characteristics.
On Tuesday 3 July 2018, News24.com announced the 100 Young Mandelas of the future. Among those nominated was Sikhululekile Luwaca, a former president of the Student Representative Council (SRC) at the University of the Free State (UFS).
 
“It is humbling. I embrace collective action and it would be unfair not to appreciate all the great minds I have encountered over the years and had the privilege to work with. Our individual progress can never be separated from that of the community. It is no longer I that lives, but us, we,” said Luwaca.

Six million readers nominated 1 000 South Africans from all walks of life who could be considered Mandelas of the future. Luwaca emerged in the Visionary category as one of the 100 who made the cut. The initiative was inspired by what would have been Nelson Mandela’s 100th birthday on 18 July 2018. “News24 set out to honour 100 young South Africans who embody the characteristics Mandela was best known for,” said a statement by News24.

While he was the SRC president, Luwaca’s office played a critical role in raising R1.2 million for underprivileged students. He continues to make major strides as the current chairperson of the UFS African National Congress Youth League (ANCYL). 

His social and political influence goes back to when a 13-year-old Luwaca founded an association that sought to address school dropouts in rural areas. In high school, the young philanthropist established an organisation that collected and distributed food for needy elders of Cathcart township in the Eastern Cape. For five years Luwaca served the Student Christian Organisation as chairperson. In 2013, he co-founded the Ubuntu School Project that donated 100 full school uniforms to Phomolong High School learners in Tembisa.

Later on as a UFS student, Luwaca helped found the Hand2Hand Student Association which drives fundraising initiatives, as well as the collection of non-perishable food items and second-hand textbooks for disadvantaged students. In 2015 he was elected a Residence Committee representative for House Outeniqua and SRC: Dialogue and Association. 

Luwaca was instrumental in facilitating a series of dialogues on transformation such as the Fees Must Fall movement and the Shimla Park incident.

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.
