Prof Abdon Atangana
Prof Abdon Atangana is known for his work in developing a new fractional operator used to model real-world problems arising in the fields of science, technology, and engineering. He was recently awarded the TWAS Mohammad A. Hamdan Award by The World Academy of Sciences.

Prof Abdon Atangana, Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS), was awarded the TWAS Mohammad A. Hamdan Award by The World Academy of Sciences for the advancement of science in developing countries.

It is the first time that the TWAS Mohammad A. Hamdan Award was bestowed. According to a statement issued by TWAS, this award is given for outstanding mathematical work carried out by a scientist working and living in Africa or the Arab region. It states that the award can be given for work in pure mathematics, applied mathematics, probability, or statistics. Prof Atangana received the award for his contribution to fractal mathematics and partial differential equations.

Making a difference in society

He is known for his research in developing a new fractional operator, the Atangana-Baleanu operator, which is used 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.

His work can be applied to make complicated predictions in the fields of science, technology, and engineering. His models can, for instance, help 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.

Prof Atangana’s models can also help to advise people drilling for water by predicting how groundwater is flowing in a complex geological formation. These are only two examples of how his work can be applied to make a difference in society.

The award from TWAS is the third prestigious commendation he has received in the past month. He was recently named as one of the top 1% scientists on the global Clarivate Web of Science list. His name also appeared on a global list of leading scientists published by Stanford University in the United States. The list is the result of a study published in PLOS Biology, a peer-reviewed open-access journal.

World’s most accomplished scientists

Honours awarded by TWAS and its partners are among the most prestigious for research in the developing world. They recognise outstanding achievements and contributions to science and acknowledge the best work by scientists from the global South.

TWAS, founded in 1983 by a group of scientists under the leadership of Pakistani physicist and Nobel laureate, Abdus Salam, believes that developing nations – by growing strength in science and engineering – will be able to address challenges such as hunger, disease, and poverty, through their knowledge and skills.

TWAS is represented in 100 countries, and of the more than a thousand elected fellows, 14 are Nobel laureates. Eighty-four percent of these fellows are from developing nations. TWAS fellows are also some of the world’s most accomplished scientists.

Since the 1800s the manipulation of photographs has been common practice, and who can forget the OJ Simpson Time magazine cover in 1994? Albe Grobbelaar, lecturer in the Department of Communication Science at the University of the Free State (UFS), asked in a special lecture on 18 August 2017 whether “Photo manipulation in Journalism” was an evil habit, a crutch or a lifebuoy.

“As a journalist I have always been interested in photography. And the principle of photo manipulation or tampering with photos, as we call it, is something that has interested me ever since,” Grobbelaar said. Photo manipulation is an area that has garnered many academic interest and is not a new trend but a practice that started in the 1830s when photos came into popular use. “It is not always done with ulterior motives, artists played with photographs to get unique effects.” Photo manipulation is not only to create fake news, but is sometimes used to convey novelty and create shock to news readers. 

Different viewpoints for different circumstances
He talked about the spectrum of viewpoints on photo manipulation. Some conservative journalism schools say photos should never be retouched while other feel it is fine to tamper with pictures. “What I tried to convey in the lecture was that one should consider different circumstances differently,” Grobbelaar said. As a journalist he believes that news photos should never be manipulated.

He mentioned the example of the mugshot of OJ Simpson that the Los Angeles Police Department released to the media. “Newsweek and Time both used the photo on their front pages, but Time deliberately darkened the picture so that OJ, a black man, would appear more sinister,” Grobbelaar said. It is, however, common practice in the fashion industry to retouch images that are used in fashion magazines. 

Use own judgment to validate photos
In the age of social media it has become easy to manipulate photos and which has been labelled fake news. “I would advise people to use their own judgment when validating the authenticity of photos,” Grobbelaar said. It is important to verify whether they are from a reliable news outlet.
