We are indeed privileged to have this paper from Prof Toyin Falola to include in our celebrations of Africa Day. Toyin Falola is a world-renowned African. A scholar of African history and African studies, he holds the Jacob and Frances Sanger Mossiker Chair in the Humanities at the University of Texas, Austin. He has published, as author or editor, more than 100 scholarly books on topics ranging from diaspora, migration, empire and globalization to intellectual history, international relations, religion and culture. He has been awarded seven honorary doctorates and has received, among many other awards, the Distinguished Africanist Award from the African Studies Association, the Ibadan Foundation Award for Professional Excellence in Scholarship and the Cheikh Anta Diop Award for Excellence in African Studies. He served as Vice President of UNESCO’s International Scientific Committee, Slave Route Project from 2011 – 2015 and currently is a member of the Carnegie African Diaspora Fellows Programme and the International Committee of the Thabo Mbeki African Leadership Institute at UNISA.

In this wide-ranging paper, originally presented as keynote address at the Visions of African Unity (1930s – 2018) conference at the University of the Free State, Prof Falola begins with a tour of the intellectual history of ideas of African Continentalism (Pan-Africanism / African Unity), from Henry Sylvester Williams, through WEB du Bois, Marcus Garvey, George Padmore and Julius Nyerere, to Kwame Nkrumah. He then describes the current institutional landscape of African unity and present-day intellectual versions of African Continentalism. Asking, and answering the question ‘Why must Africa unite?’, he then proceeds, on the basis of a consideration of more contemporary intellectual versions of African continentalism such as Black Consciousness, Black Nationalism, Afropolitanism, and now Afrofuturism (which he depicts as ‘ideological dispensations of true African cultural recovery and re-orientation’), to propose a disaggregated approach to contemporary African unity that is not fixated on global-Northern models. This means that unity should (re)start small, working territorially from regional units toward a continental unit, on the one hand; and on the other, seeking unity and cooperation around discrete substantive themes, from the more obvious and traditional, such as economic policy, global politics and a reformed unified political and military system, to the less, such as common educational policy, synergizing science and technology with African culture(s) and language, culture and literary exchange.

We thank him for the gift.

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.
