Drawing from different international perspectives on the topic of historical statues, the importance of debate surrounding the future of these symbols resounded at the 10th Annual Africa Day Memorial Lecture. 

The lecture was hosted on 23 May 2018 by the newly renamed Centre for Gender and Africa Studies and was presented by Dr Rahul Rao from the SOAS University of London, where he is a senior lecturer in Politics. 

“I am very excited about my trip to South Africa and to be here among you. This is my first trip to South Africa, and it is very exciting and also a little bit emotional for me, particularly because I got my first passport in 1984 when I was six years old, and it said – valid for travel to all countries except the Republic of South Africa. You know why that was the case.”

“I salute all of you for the transformation that has been affected in this country, and I think Africa Day is the perfect occasion to celebrate the transformation.”  

Student activism through #MustFall movements
“I first heard in March 2015 that students from the University of Cape Town have begun demonstrating to take down the statue of Cecil John Rhodes and have it removed from their campus, and a bit later, students from the University of Oxford in the United Kingdom followed suit. At first, I felt some guilt having been a Rhodes Scholar from 2001 to 2004, because you must embody the values of Cecil John Rhodes,” Dr Rao said.

“I have watched from afar the events that have taken place here, for example, the #RhodesMustFall Movement, and the reverberation of these events in other places; I mean, the way these events travel,” he said.

Students in Cape Town, Oxford, and Bloemfontein are doing something concrete and collective to dismantle the legacy of colonialism and Apartheid. “I feel connected to these events, even if I am far away.”

International perspective on historical statues
In both SA and the UK, the call for iconography decolonisation was accompanied and soon overtaken by different accounts. It also gives a broader and different perspective on how statues can be used to achieve racial or social dominance. 

One of the many examples he used, was the ambush against Confederate Statues in the American South. These statues are symbols of upholding a white supremacist ideology in the South. The Confederate States of America was the predecessor to the current United States of America.

He also spoke about the temporalities of statues, the decolonisation and recolonisation, as well as the aesthetics of statues, among other things. “Statues don't need permission to thrust itself upon us. They demand attention,” Dr Rao said. This is because statues are placed in the centre of public spaces but are also vulnerable and exposed. 

He left the audience with some questions on what to do with statues that are taken down, and who to erect new statues for.

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

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.
