Prof Mongane Wally Serote said South Africa was created with people from all over who made this their home.
The Centre for Gender and Africa Studies (CGAS) prides itself in creating spaces for intellectual discourse. This was illustrated in a Heritage Day lecture webinar presented by National Poet Laureate, Prof Mongane Wally Serote. The lecture was in collaboration with the University of the Western Cape (UWC) and the Department of Sports, Arts and Culture.

The lecture took place on 23 September 2020. Dr Stephanie Cawood, director of CGAS was the programme director. 

Diversity is our biggest heritage

Prof Serote presented the webinar under the theme Going to Basics: The Reconstruction and Development Programme of the Source. “As South Africans, we came from everywhere and created a home here –- we are the microcosm of the world,” Prof Serote said as he started his lecture. He also said that diversity is the biggest heritage the country has, and that it is a cultural expression emanating from our most complex and difficult history.

The Constitution of our country is a piece of valuable evidence in the commitment to overcome our historical adversities. “Understanding our history seeks to persuade us as a nation, and to understand that change, is constant in the dynamism and dialectics of time,” said Prof Serote. He explained this by saying that, as a nation, we must become masters of knowledge of the constant systems of change and the management thereof.

“Since the outbreak of the coronavirus pandemic, we have quickly arrived at making fundamental changes and transformation,” he said. This is because the world is changing dramatically and very fast. “The biggest and most important lesson is that we dare not forget that humanity is one,” he said.

Social cohesion and nation building a shared responsibility 

As much as the webinar commemorated Heritage Day, it was also a poignant reminder of the role that universities have to place in society at large. “We at the UFS pride ourselves on providing space for debates. This is what we are hosting here today,” said Dr Chitja Twala, Vice-Dean of the Faculty of the Humanities at the UFS.  Dr Twala also said that Heritage Day is one of the milestone days on which “Africans pride themselves”.

The Deputy Minister of Sports, Arts and Culture, Nocawe Noncedo Mafu, referred to Dr Twala’s sentiment, saying that events such as these should be hosted “to foster social cohesion and nation building, which cannot succeed if it remains a project solely and exclusively owned by government”.  Deputy Minister Mafu reiterated that social cohesion and nation building should be a concern for the rest of the society. “I am therefore thrilled with this lecture and notably the partnership with the two universities," she said.

The national theme for Heritage Month 2020 is ‘Celebrating South Africa’s Living Legends.’

What do diamonds, chocolates, bugs and almost 30 Nobel Prizes have in common? Crystallography
2014-10-15

 

Some of the keynote speakers and chairpersons at the third world summit in the International Year of Crystallography (in Africa) were, from the left, front: Profs Abdelmalek Thalal (Morocco), Prosper Kanyankogote (University of Kinshasa, Democratic Republic of the Congo); Habib Bougzala (Tunisia), Santiago Garcia-Granda (IUCr, University Oviedo, Spain), Michele Zema (IYCr 2014, Italy/UK) and Dr Jean-Paul Ngome-Abiaga (UNESCO, Paris, France); back: Dr Thomas Auf der Heyde (Acting Director-general, South African Department of Science and Technology); Dr Petrie Steynberg (SASOL) and Prof André Roodt (UFS, host).

The third world summit in the International Year of Crystallography (in Africa) was hosted by Prof André Roodt, Head of the Department of Chemistry and President of the European Crystallographic Association,  at the University of the Free State in Bloemfontein.

A declaration with and appeal to support crystallography and science across Africa, was signed.

When one mentions 'Crystallography', or more simply 'crystals', what comes to mind? Diamonds? Perhaps jewellery in general? When thinking of crystals and Crystallography, you will need to think much bigger. And further – even to Mars and back.

Crystallography refers to the branch of science that is concerned with structure and properties of crystals. The obvious examples would include cut diamonds, gemstones such as amethysts, and ‘simple’ crystals such as selenite and quartz.

But have you thought about the irritating brown scales at the bottom of your kettle? The sand in your shoes? The salt over your lamb chops or the sugar in your coffee? All crystals. From egg shells to glucose, from bugs and insecticides to additives in food – even the compounds in chocolate – all fall under the close scrutiny of Crystallography.

The breakthroughs this field of science has produced have led to almost 30 Nobel Prizes over the years.

Determining the structure of DNA by crystallography was arguably one of the most significant scientific events of the 20th century. Different diseases have been cured or slowed by medicines obtained based on crystallographic studies. These include certain cancers, HIV/Aids, Tuberculosis and Malaria. Biological Crystallography enables the development of anti-viral drugs and vaccines.

This field of science influences our daily lives in virtually immeasurable ways. Here are but a few areas of study and development Crystallography contributes to:

•    LCD displays;
•    cellular smartphones;
•    insects and insecticides;
•    additives and products in foods;
•    improved effectiveness and security of credit cards;
•    new materials to preserve energy;
•    better gasoline with less by-products;
•    identify colour pigments used in paintings from the old masters, indicating if it’s an original or an imitation; and
•    beauty products such as nail polish, sun-block, mascara and eye shadow.

Crystallography is also currently used by the Curiosity Rover to analyse the substances and minerals on Mars.

Crystals and Crystallography form an integrated part of our daily lives – from bones and teeth to medicines and viruses, from chocolates to the blades in airplane turbines. Even down to the humble snowflake.
