Reflecting on the past, present, and future of Africa

UFS Africa celebration — I am not African because I was born in Africa, but because Africa was born in me,” Kwame Nkrumah, Ghana’s first president, and a founding father of the African Union.

Since the African Union’s establishment in 1963, the continent marks Africa Day on 25 May annually. To commemorate the achievements made by African leaders 56 years ago to decolonise the continent and pave the way for a united front on the global stage, the University of the Free State (UFS) hosts various events.

Ubuntu our beginning, ubuntu our ending

The university celebrated Africa Day a day early this year. The Office for International Affairs coordinated the 2019 Africa Day Reflection and Celebration on 24 May 2019 at the Bloemfontein Campus. A dialogue session delved into the question of what ubuntu has evolved to mean in modern-day society and how best it can be embodied.

Moderator of the dialogue, Ace Moloi, reckoned that “we have a right not only to give ubuntu but to demand and invoke it from other people.” Staff, students and panellists engaged on the aphorism umuntu ngumuntu ngabantu and whether the philosophical principle is a pragmatic way of doing things or is only referred to when self-correcting.

Prof Colin Chasi, from the UFS Department of Communication Science, touched on how ubuntu is embedded in many Nguni languages. A case in point being the implied presence and connectivity typical found in indigenous language greetings. Other panellists including Prof Karin van Marle( Public Law lecturer at the UFS), Thapelo Mokoatsi,History lecturer at the UFS and Matau Setshase, UFS researcher, made contributions on decolonisation, individual identity, reconciliation, social issues, and traditional healers. The consensus reached was that a lot work still needs to be done in understanding and living the values represented by ubuntu.

Qwaqwa Campus Celebration

The Office for International Affairs (OIA) also hosted the first Annual Africa Day Student Dialogue on the Qwaqwa Campus under the theme: Health, Wellbeing, Access, Social inclusion, Equity and Equality on the African continent.

Africa Day Memorial Lecture

Presenting the 2019 Africa Day Memorial Lecture, Prof Francis Nyamnjoh, from University of Cape Town, delved into the topic of Ubuntuism and Africa: Actualised, Misappropriated, Endangered and Reappraised. “I seek to give currency to concepts such African communitarianism, ubuntu, Africanness, Afrocentricity, Afrocentrism, Africanity, Afrikology, humanness, wholeness and reciprocal altruism,” he said.

Hosted by the Centre for Gender and Africa Studies on 22 May 2019 the annual lecture is a calendar constant which reflects on the importance of celebrating the continent and its people.

Migration debate unpacked borders

The UFS Debate Society reflected on borders and migration in Southern Africa on 21 May 2019. The debate unpacked the topic: The Southern African Development Community should develop a free internal migration policy.

Lecturers also delivered presentations that dissected African societies, the nine frontier wars between the British and amaXhosa that formed South Africa’s borders, and the influence of labour and capital on migration. In closing, African international students shared their lived experiences, hardships and triumphs within the continent.

Discovery in Scorpius constellation may signify clean energy for Earth

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
