International Mother Language Day

The Office for International Affairs recently celebrated International Language Day.  This year, we invited all faculties to submit the names of people who would be willing to contribute video clips to educate us about their mother tongue.  The videos submitted were from diverse academic staff members and postdoctoral fellows currently based in different parts of the world.  Extensive research has created this edutainment video, featuring famous language quotes, indigenous languages across the African continent, and business languages used across the African continent. Some of the indigenous languages on the African continent are fading away, caused by colonial influence.

Fun facts:
From 1994 to 2013, South Africa was in the Guinness Book of World Records for most official languages.  These are Afrikaans, English, Ndebele, Sepedi, Sesotho, Swati, Tsonga, Tswana, Venda, Xhosa, and Zulu.

Since the adoption of the 2013 Constitution, Zimbabwe now holds this title with 16 official languages, namely Chewa, Chibarwe, English, Kalanga, Koisan, Nambya, Ndau, Ndebele, Shangani, Shona, Sign Language, Sotho, Tonga, Tswana, Venda, and Xhosa. Zimbabwe therefore now holds the Guinness World Record for the country with the largest number of official languages.  

Albeit the main languages in Zimbabwe are English, Shona and Ndebele, the minor languages are Chewa, Chibarwe, Kalanga, Koisan, Kunda, Lozi, Manyika, Nambya, Ndau, Nsenga, Tsonga-Shangani, Sotho, Tjwao, Tonga, Tswa, Tswana, Venda, and Xhosa.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
