It has been a journey filled with mountains, valleys, rivers, and seas.

Growing up a top achiever, I thought life would be smooth sailing, but like most of us, my first rude awakening came when I lost my mother in 2010. I had to learn to rely on myself and others to keep my head above water. I ask for help when I need it, so I use the services of professionals from time to time.
 
One of the most valuable tools I use, is my gift of singing. I call it my cup filler. I have songs for every mood. I have playlists of songs that I sing along to, pieces that help me balance.
   
I have learnt over the years that I need fuel just like a car needs energy. Moreover, a vehicle needs more than just fuel to function efficiently. I apply the same metaphor to my mental well-being. Besides music, I fuel myself up by doing good to others. 

I love spending time with my dogs, and they know how to make me smile without saying much. I have recently started reflective journaling, and I find it very useful to interrogate thoughts that are not healthy for me. Overall, I remind myself that I am not perfect, and that life is about balance. 

When the scale starts tipping to the one side, life will always calibrate itself into balance, and sometimes those calibration moments are when I feel stressed and overwhelmed. Mine is not to go into panic mode, but to work with life towards achieving that balance again. Over the years, I have noted that this process is a never-ending one.

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.”
