As we as a South African nation prepare to celebrate Heritage Day on 24 September, and as we reflect on our heritage during Heritage Month, what stands out clearly is that this year’s heritage celebrations will be somewhat … different. It will not be like previous celebrations because as a country, we – along with our fellow continental and global citizens – have experienced what can be described as one of the greatest health, social, and economic challenges that we as a species have ever faced. The repercussions and impact of the COVID-19 pandemic will be felt for some time to come. And it is this realisation that may cast a little damper on our celebrations during this #Heritage Month.

But what can our shared heritage as South Africans teach us about who we are as a people, and how can this knowledge help us to adapt to and overcome the long-term challenges wrought not only by the pandemic, but also by the many other challenges facing us? 

Heritage Day is a celebration of our cultural heritage and diversity as a nation. It presents us with an opportunity to reflect on our individual and collective heritage. It is also an opportunity for us to take stock of the cultural and other resources that enable and empower us to take ownership of what we want to be as a nation, as a country, as a people. 
So, in view of the questions raised earlier, here are some ideas on what I think our shared heritage can teach us:

1. The heritage of where we come from

Inasmuch as our past is a painful one – a past that still has lingering effects decades after the transition to a democratic dispensation – it still plays a fundamental role in shaping who we are now, and who we want to become.
Colonialism and apartheid sought to suppress our indigenous cultures and traditions, and had a negative impact on our psyche, self-confidence, and dignity as indigenous and African people. But one positive that came from this, is that if it was not for our shared heritage of colonialism and apartheid, we probably would not have become the nation we needed to become to bring it to an end.  

Instead of destroying symbols of that painful past, we need to shift our perspective to re-interpret those symbols in a new way. The power of cultural symbols lies in their meanings. Symbolic anthropologist Victor Turner spoke about the ‘multivocality of symbols’, meaning that we can ascribe whatever meanings to our cultural symbols we choose. Let us reflect on how we can change the current meanings we ascribe to our cultural symbols that reflect an awareness of how the heritage of where we come from does not keep us trapped in negative and painful meanings of these symbols, but instead inspire us to create new positive meanings.

2. The heritage of where we are now

After 1994, we began the process of creating a new contemporary heritage as a nation struggling to free itself of the burden of a painful past. And while it was difficult, we have made significant strides. Yes, we do still face challenges rooted in the past: institutional and structural violence; race and diversity-related issues; intercultural and intergroup conflicts; crime and violence against men, women, and children; corruption at various levels of governance; and others. We are also faced with ‘newer’ challenges as a country that is part of the globalised world. Poverty, inequality, unemployment, slow economic growth, and ailing infrastructure are all contemporary problems, some of them rooted in the past, others the product of the contemporary context. 

What can we learn from our shared heritage of where we are now that can help us to overcome these contemporary challenges? We need to remind ourselves of what we are capable of as a nation. We have ended an oppressive regime, not once but twice. And, with all of the challenges, problems, and obstacles, we are still here.

3. The heritage of where we are going

This might sound strange, because heritage usually refers to the past and present. Rarely do we speak of heritage in a future-oriented context. However, as a nation, given our past and given our present, where we come from and where we are now determines where we are going. 

As South Africans, we need to ask the question: where do we want to go? Are we heading in that direction? If not, how do we change course so that we do go in the right direction? I have no simple answer. But what I can suggest is that it should start with critical self-reflection, both individually and collectively. We also need to ask ourselves what legacy we want to leave for future generations. Do we want them to still be struggling with the same problems and challenges that we are dealing with right now? Or do we want to leave them a legacy of a nation that stood up to its challenges, took ownership of them, and found a way to overcome them?

A globally devastating pandemic. A painful past. A present wrought with seemingly insurmountable obstacles. As a South African, as a child of the soil, I know that as a nation we can overcome, and we can emerge better and stronger. That is our heritage. The heritage of hope.

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.
