Commonwealth read more — Takudzwa Nyamunda represented the UFS at the latest Commonwealth Futures Workshop where youth from across the globe convened to develop solutions for social issues.

Gender-based violence, global warming, and inequality are just some of the challenges faced by societies internationally. Examining this and other topics Takudzwa Nyamunda represented the University of the Free State (UFS) at the Commonwealth Futures workshop which convened at the Durban University of Technology (DUT). Participants from 13 nations gathered from 11-14 March 2020 to discuss the future of the world.

Over the course of four days, student leaders explored ways of bringing peace and nonviolence to the challenging issues we are facing in the world, under the theme: Reimagining Peace. The workshop was organised by the DUT in collaboration with the Association of Commonwealth Universities (ACU) and the British Council.

The voice of young people
International forums such as the Commonwealth Futures workshop are to Nyamunda a prerequisite in these modern times. Nyamunda believes that global problems warrant global solutions. According to the Industrial Psychology Master’s student, young leaders have a crucial role to play in nation-building.

“My experience proved to me that the differences that come out of our diversity are indeed a source of strength demonstrated by the rich insights that came out of the conference,” said Nyamunda who is also an employee of the UFS Department of Human Resources.

Producing practical solutions
The three-tiered workshop aimed to bring change to campuses across the world, in communities and beyond. This was the third workshop in the series which has taken place in India and the UK. The outcomes will directly feed into the 2020 Commonwealth Youth Forum to be held in Kigali, Rwanda later this year.

The group of students worked together to develop tangible solutions that address shared global issues such as gender-based violence, climate change and inequality. Joining the young leaders were expert speakers and organisations including the International Centre of Nonviolence, the Gandhi Development Trust, as well as the Commonwealth Countering Violent Extremism (CVE) Unit.

Global solutions for global problems
The Commonwealth states that with more than 60% of the Commonwealth’s 2.4 billion people younger than 30, the voices of young people have never been more important. Students across the globe are setting new agendas for social debates, challenging communities and governments to listen and work with young people to develop solutions to these intersecting issues and bring about real change.

In joining forces with other young thought leaders from around the world, Nyamunda drew on his experience as an International Students Association Founder and first President, the former 2017 Student Representative Council (SRC) member for International Students, and the Vice-Chairperson of the South African Board for People Practices: UFS Chapter.

As one of the 40 delegates from across the globe, Nyamunda was given a sense of hope after he witnessed how keen young people are to build a better future.

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.
