Prof Abdon Atangana was recently elected a fellow of The World Academy of Sciences (TWAS).

Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS), was recently elected a fellow of The World Academy of Sciences (TWAS).

He also received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A. Hamdan, 2020) on 1 November 2021.

TWAS, described as the voice for science in the South, is working towards the advancement of science in developing countries and supports sustainable prosperity through research, education, policy, and diplomacy. 

Outstanding contribution to science

Prof Mohamed HA Hassan, President of TWAS, congratulated Prof Atangana on this prestigious achievement, “Your election as fellow is a clear recognition of your outstanding contribution to science and its promotion in the developing world. We will be honoured to have you among our members.”

Candidates elected as TWAS Fellows are scientists whose contributions to their respective fields of science meet internationally accepted standards of excellence, and they must have distinguished themselves in efforts to promote science in developing countries. 

Prof Atangana is known for his research to develop a new fractional operator, the Atangana-Baleanu operator, which is to model real-world problems. With this operator, he not only describes the rate at which something will change, but also account for disrupting factors that will help to produce better projections.

Among others, his models can advise people drilling for water by predicting how groundwater is flowing in a complex geological formation. Furthermore, his work can also be applied to predict the spread of infectious diseases among people in a settlement, forecasting the number of people who will be infected each day, the number of people who will recover, and the number of people who will die. 

These are only two examples of how his work can be applied to better the lives of people.

Promoting science in the developing world

Besides promoting science in the developing world, Prof Atangana’s work also contributes to the United Nations Sustainable Development Goals – the global goals as set in 2015 that call for ending poverty, protecting the planet, and ensuring that all people enjoy prosperity and peace.

Prof Atangana says the election as fellow is a clear recognition of his outstanding contribution to science and its promotion in the developing world. “My work over the past five years has made a great impact in all fields of science, technology, and engineering.”

To be elected as TWAS fellow in mathematics, made him the second South African researcher to be elected in the field of mathematics (the first person elected was Prof Reddy Batmanathan Dayanand, who was elected in 2003). This also placed him as the sixth African mathematician to be elected as a TWAS fellow.

Very recently, he also ranked number one in the world in mathematics, number 186 in the world in all the fields, and number one in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Less than 6 200 or 0,1% of the world's researchers were included on this list in 2020, with no more than 10 of the scientists hailing from South Africa. 

Prof Atangana is also editor of more than 20 top-tier journals of applied mathematics and mathematics, and for some of these journals he was the first African to be selected as editor.

On Friday 4 December 2015, Penny Siopis, the well-known Cape Town-based artist, who has been exhibiting her work locally and internationally since 1975, was presented with the 2015 Helgaard Steyn Award and a prize of R 550 000 for her painting entitled Swarm.

A quadrennial award lunch was hosted by the University of the Free State (UFS) Johannes Stegman Gallery in conjunction with the Helgaard Steyn and ABSA Trusts. The Helgaard Steyn Trust was established by the estate of Dr Jan Steyn and was named after his father and his brother who was the last president of the Orange Free State Republic.

Swarm, a 2011 painting using ink and glue on canvas, depicts a swarm of bees in a complex, dynamic, and intense manner. It earned the prestigious award that is dedicated to the promotion of artistic culture based on the adjudicators’ unanimous decision. Angela de Jesus, curator of the Johannes Stegmann Art Gallery at the UFS, Annali Dempsey of the University of Johannesburg Gallery, and Prof John Botha, Associate Professor in Art History at North West University, made up the 2015 panel of judges.

On receiving the award, Siopis thanked the Steyn family, the judges, and the people who nominated her. “I am struck by how fantastic it feels to be acknowledged. It is extraordinary when people are struck by what was your own world and the intensity buzzing in your head.”

According to Prof Botha, “Naturally the work of art is chosen on grounds of artistic merit and in the context of contemporary values with regards to both form and content.”

The award-winning painter studied Fine Arts at Rhodes University and Portsmouth University in United Kingdom. Apart from lecturing Fine Arts at the University of the Witwatersrand, she is an honorary professor at University of Cape Town Michaelis School of Fine Art. She has also taught at the Natal Technicon in Durban.

Siopis has received numerous awards for her work, including a British Council Scholarship, a Merit Award at the 2nd Cape Town Triennial, and the Atelier Award for a residency at the Cité Internationale des Arts in Paris, in addition to the Alexander S Onassis fellowship for research in Greece.
