“I believe the Hesselbein Global Academy annual fellowship programme was vital for me as a potential public servant of South Africa to serve the people of this country in government one day.” – Kofi Yinkah

University of the Free State (UFS) third-year BAdmin student, Kofi Annan Yinkah, formed part of the Hesselbein Global Academy annual fellowship programme, hosted by the University of Pittsburgh in the United States of America (USA). Originally from the East Rand in Johannesburg, Kofi represented the UFS as one of the top-50 students who were selected out of 450 global applicants.

The Hesselbein Global Academy annual fellowship programme aims to connect young leaders from all over the world with well-equipped professionals who are leaders in the fields of business, government, and education. This programme was established for the purpose of cultivating and producing cadres who will become experienced ethical leaders, armed and qualified enough to address and solicit solutions for critical issues experienced by diverse societies throughout the world.

“The fellowship covered topics that have helped to broaden my critical thought processes and concerns about societal issues in our country and all over the world. It has also emphasised the importance of implementing change through effective governing-policy development and establishment,” Kofi says.

He describes his experience at the fellowship as “out of the ordinary,” and believes that it has had a progressive influence on his life. He explains how it has unlocked his mind through enlightened engagement with student leaders from various countries in the world, including Nigeria, England, Canada, Chile, Trinidad and Tobago, Vietnam, China, United States of America, and Ireland.

One of the most important tools he believes his experience has equipped him with, is understanding the significance of employing a solution-driven approach to various situations. He is confident that this will give him the necessary skills and knowledge to work effectively in teams.

Kofi explains that he found out about the fellowship programme via social media. He encourages UFS students to use online platforms to source information about opportunities that can offer them meaningful experiences for learning and growing.

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.
