4IR Prof Marwala

A computer programmed to play poker and learning by itself how to bluff; an algorithm that predicts whether two countries will ever go to war; machines that detect epilepsy with almost flawless accuracy these are some of the groundbreaking abilities brought about by technologies associated with the Fourth Industrial Revolution (4IR).

Addressing the first UFS public event to enhance 4IR awareness, Professor Tshilidzi Marwala, Vice-Chancellor and Principal of the University of Johannesburg, briefed staff, interested parties and members of the media about recent 4IR developments and their implications.

Prof Marwala is currently a thought leader on the impact of the 4IR on higher education in South Africa as well as the Deputy Chairperson of the national commission appointed by the president to formulate 4IR strategies for South Africa.

Industrial revolution history

He recapped how, during the first industrial revolution, people started to understand how nature worked, ultimately leading to the development of the steam engine.
The second industrial revolution was marked by the development of electromagnetism which led to electrification and mass production, while the third produced computerisation and a rise in digital technology. 

The fourth industrial revolution is characterised by a fusion of technologies that blur the lines between cyber, physical and biological systems. This has led to rapid advances in fields such as artificial intelligence, quantum computing and 3D printing.


Artificial intelligence

Prof Marwala pointed out that, although fears were rife of machines taking over people’s jobs, the flipside of the coin was that dangerous jobs such as fire rescue operations could be carried out by machines without endangering lives.

Artificial intelligence can be employed to prevent bridge and building collapses by monitoring the condition of structures. It can also be used in credit scoring, where machines search for and analyse all the available data on a credit applicant, without having to rely only on the (sometimes fraudulent) information supplied by the credit seeker. 

He emphasised the great need to develop algorithms applicable to our continent, such as translating software that makes provision for the clicks in languages like isiXhosa, and facial recognition software that incorporates data collected in African countries. 


Is Africa ready? 

Responding to a question from an audience member, Prof Marwala indicated that Africa was certainly not ready for the 4IR when it came to the content of teaching curricula and infrastructure.

“As universities, we should not sit back and wait for change. We have the responsibility to lead our societies to have the same experiences as elsewhere in the world,” he concluded.

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.
