The Centre for Mineral Biogeochemistry (CMBG) at the University of the Free State (UFS) was part of another successful Tritech National Science and Technology Fair 2023 – an exciting STEM (Science, Technology, Engineering, and Mathematics) research competition.

The UFS has partnered with Tritech and other sponsors since 2021 to bridge the gap between high school and tertiary education. Tritech, which started in 2008 and is open to all Grade 7-12 learners, aims to equip them for tertiary education by introducing them to scientific research and incorporating modern technology in research. This is an annual competition that starts at the regional level and goes all the way to the national level, with the national competition held at the Merensky High School, in Tzaneen, Limpopo from 20-21 October 2023.

Schools from across the country take part in the fair, but learners compete in groups rather than schools. 

Every year the Tritech Nationals are divided into four main activities over the weekend: 
  1. On the Friday afternoon the learners present their STEM projects in which they have identified a problem in a community, do research to find a solution, do experiments to test if the solution will solve the problem, then test the solution in the community, and lastly, present their findings to a group of judges and learners in similar fields. Fields include Life Sciences, Engineering and Design, Maths, Science and Technology, Environmental and Social Sciences, Health Sciences and Agricultural Sciences.
  2. Friday evening is usually a fun activity for the learners.
  3. On Saturday morning the learners are exposed to work-related activities that give them insight into professions they could pursue in the science field. This activity is sponsored and presented by the UFS. 
  4. The last activity of the weekend is the prize-giving on Saturday afternoon where the learners get rewarded for the quality of their projects and honour, celebrate, and encourage excellence. 

“Every year the CMBG includes different departments from the UFS in alignment with the theme for the event, to ignite a lasting passion for innovation toward promising careers in the STEM fields. In 2022 the theme for Tritech was “Crime Scene Investigators” and the CMBG team created a very realistic crime scene and laboratory setup to teach the learners about Forensic Science. The learners scored our CSI activity as the best for the weekend and we knew that for the 2023 Nationals, we had our work cut out to do even better,” says Dr Erasmus. 

Learning about food health and safety

This year, Prof Maryna de Wit and her students from the Department of Sustainable Food Systems and Development (SFSD) joined the CMBG team, to introduce learners to food health and safety, food preservation, food systems and development, as well as sensory analyses. 

Island, shipwrecks, and wilderness survival

Dr Mariana Erasmus, Deputy Director of the Centre for Mineral Biogeochemistry (CMBG), spearheads the Tritech team from the UFS. CMBG, as part of its community outreach programme, is not only a sponsor of the event but is also the organiser of the main activity together with another UFS department. 

Dr Erasmus says the theme for Tritech 2023 was “Survival MasterChef”, where for the two activity events, the Tritech learners were “stranded” on an island. This exercise was a great way to promote leadership qualities, encourage creativity and confidence, promote teamwork and active communication, and increase critical thinking in learners, while they got to know more about food health and safety practices.

“It was all island, shipwrecks, and wilderness survival at this year’s event where learners had to survive after being ‘stranded’ on an island. To escape, the learners had to build a boat and while they waited to be rescued, they needed to adapt to island life to survive by preparing healthy meals, as well as preparing meals and drinks to treat dehydration and scurvy,” says Dr Erasmus. 

“During the prize-giving, some of the learners received shadowing opportunities at the UFS and other sponsors to advance their education. Bronze, silver, and gold medals, together with participation certificates, were awarded to other deserving learners.”

Africa the birthplace of mathematics, says Prof Atangana

Prof Abdon Atangana from the Institute for Groundwater Studies at the University of the Free State recently received the African Award of Applied Mathematics during the International conference "African’s Days of Applied Mathematics" that was held in Errachidia, Morocco. Prof Atangana delivered the opening speech with the title "Africa was a temple of knowledge before: What happened?” The focus of the conference was to offer a forum for the promotion of mathematics and its applications in African countries.

When Europeans first came to Africa, they considered the architecture to be disorganised and thus primitive. It never occurred to them that Africans might have been using a form of mathematics that they hadn’t even discovered yet.

Africa is home to the world’s earliest known use of measuring and calculation. Thousands of years ago Africans were using numerals, algebra and geometry in daily life. “Our continent is the birthplace of both basic and advanced mathematics,” said Prof Atangana. 

Africa attracted a series of immigrants who spread knowledge from this continent to the rest of the world.

Measuring and counting
In one of his examples of African mathematics knowledge Prof Atangana referred to the oldest mathematical instrument as the Lebombo bone, a baboon fibula used as a measuring instrument, which was named after the Lebombo Mountains of Swaziland. The world’s oldest evidence of advanced mathematics was also a baboon fibula that was discovered in present-day Democratic Republic of Congo.

Another example he used is the manuscripts in the libraries of the Sankoré University, one of the world’s oldest tertiary institutions. This university in Timbuktu, Mali, is full of manuscripts mainly written in Ajami in the 1200s AD. “When Europeans and Western Asians began visiting and colonising Mali between the 1300s and 1800s, Malians hid the manuscripts in basements, attics and underground, fearing destruction or theft by foreigners. This was certainly a good idea, given the Europeans' history of destroying texts in Kemet and other areas of the continent. Many of the scripts were mathematical and astronomical in nature. In recent years, as many as 700 000 scripts have been rediscovered and attest to the continuous knowledge of advanced mathematics and science in Africa well before European colonisation. 

Fractal geometry

“One of Africa’s major achievements was the advanced knowledge of fractal geometry. This knowledge is found in a wide aspect of Africa life: from art, social design structures, architecture, to games, trade and divination systems. 

“The binary numeral system was also widely known through Africa before it was known throughout much of the world. There is a theory that it could have influenced Western geometry, which led to the development of digital computers,” he said. 

“Can Africa rise again?” Prof Atangana believes it can.

He concluded with a plea to fellow African researchers to do research that will build towards a new Africa.
