Mathematician makes popular contribution to science Prof Atangana
Prof Atangana is the first African under 40 years of age to be selected as African Academic of Science affiliated in Mathematics. He recently delivered his inaugural lecture and is pictured with Eelco Lukas, Director of the Institute for GroundwaterStudies at the UFS (middle) and Prof Hendri Kroukamp, Acting Vice-Rector: Academic
Prof Abdon Atangana, researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), recently delivered his inaugural lecture on the topic: Understanding God’s Nature with Non-Local Operators.

His research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbation methods, asymptotic methods, iterative methods, and groundwater modelling. Prof Atangana is the founder of the fractional calculus with non-local and non-singular kernels popular in applied mathematics today. He has introduced more than 12 mathematical operators, most of which bear his name (such as the Atangana-Baleanu fractional integral).

He stated: “We will not stop until we change the classical view of doing mathematics. Mathematics is not a subject but a tool given to mankind by God to understand nature. One single mathematical operator cannot portray God’s nature accurately. Therefore the Atangana Baleanu was suggested.”

New weapons

Most physical problems can be expressed in terms of mathematical formulations called differential equations. According to him the differential equation’s aim is to analyse, understand, and predict the future of a physical problem. Prof Atangana introduced the Atangana-Baleanu fractional integral. This brought new weapons into applied mathematics to model complex real-world problems more accurately.

Prof Atangana explained: “The Atangana-Baleanu fractional derivative is able to describe real-world problems with different scales, or problems that change their properties during time and space for instance, the spread of cancer, the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers, and many others. This crossover behaviour is observed in many empirical systems.”

Sudden change

The Atangana-Baleanu fractional derivative is also able to describe physical or biological phenomena, such as a heart attack, the physiological progression from life to death, structural failure in an aeroplane, and many other physical occurrences with sudden change with no steady state.

The new differential and integral operators are nowadays in fashion and are being applied with great success in many fields to model complex natural phenomena. It is believed that the future of modelling complex real-world problems relies on these non-local operators.

Spring Graduation
2011-09-12

 

Our university will be awarding altogether 91 diplomas/certificates and 624 degrees during the Spring Graduation Ceremony on 14 and 15 September 2011. Of these, 23 doctorates and two honorary doctorates will also be awarded.

As with this year’s Autumn Graduation Ceremony, we will be making the ceremony more accessible to students and the public. Two appearances, in particular, can be looked forward to on this occasion: a national concert pianist in Grade 12 from Voortrekker High School in Bethlehem, Caryn Reed, and a continental debating champion and second-year student in our Faculty of Economic and Management Sciences, Sibusiso Tshabalala, as guest speaker.
 
All the master’s and doctoral degrees of the various faculties will once again be awarded during one ceremony on 15 September 2011.
 
Prof. Robert Frater, Emeritus Professor in Thoracic and Cardiovascular Surgery, and Emeritus Professor of Paediatrics, Albert Einstein College of Medicine and Montefiore Medical Centre, New York, will be receiving an honorary doctorate in Medical Science. As a teacher and trainer, Prof. Frater has influenced many surgeons in his training role in the wards, operating room and intensive care facility. Dr Akilagpa Sawyerr, an academic from Ghana, will be receiving an honorary doctorate in Education for groundbreaking work done on the African continent. Dr Sawyerr, who is a member of our International Advisory Council, has visiting appointments at prestigious universities, such as the famous Fletcher School of Law and Diplomacy at Tufts University. He also has visiting status at the Harvard Law School and the Yale Law School.
 
The full programme for the various ceremonies is:
  • Wednesday, 14 September 2011:
At 10:15, the degrees will be awarded to students of the Faculties of Humanities, Education, Law and Theology. Diplomas/certificates up until honours degrees will be awarded. This excludes the Certificate in Education, National Professional Diploma in Education and the Advanced Education Certificate.
 
At 15:15, degrees will be awarded to students in the Faculties of Economic and Management Sciences and Natural- and Agricultural Sciences and Health Sciences. Diplomas/Certificates up until honours degrees will be awarded.
  •  Thursday, 15 September 2011:
At 10:15, a total of 125 master’s and doctoral degrees plus two honorary doctorates will be awarded by all the faculties in a joint ceremony.
 
The Chancellor’s Dinner will also take place on the same day.
