NITheCS & AIMS host first joint Public Lecture

NITheCS hosted a public lecture – for the first time in collaboration with the African Institute for Mathematical Sciences (AIMS) – titled “Patterns and Tessellations: Models for Regular Structures” at STIAS in Stellenbosch on 19 February 2026.

The event was well supported by students, academics and members of the public for an engaging exploration of the mathematics behind repeating patterns and geometric structures.

The presenter, Dr Michael Winckler, Administrative Director of the Interdisciplinary Center for Scientific Computing at Heidelberg University, Germany, explored how tessellations serve as powerful models for understanding order and symmetry in both natural and human-made systems. From tiling patterns in art and architecture to crystalline structures in materials science, he demonstrated how mathematical principles reveal underlying regularity, symmetry and structural efficiency.

Through clear explanations and visual examples, Dr Winckler introduced key concepts such as symmetry groups, geometric transformations and the classification of regular patterns. The lecture illustrated how seemingly simple tiling designs connect to deep mathematical theory and contemporary scientific applications. He also demonstrated how to tile a plane using origami, guiding participants in how to create a two-dimensional pattern capable of repeating indefinitely and encouraging them to try it at home.

NITheCS Director Prof Francesco Petruccione briefly addressed the audience, followed by AIMS Director Karin-Therese Howell, who thanked NITheCS and Heidelberg University for their partnership. She emphasised how collaborations such as this strengthen the scientific community and expand the reach of mathematics across institutions and continents, particularly in light of representation from both Europe and Africa at the event.

The lecture concluded with a networking session over refreshments.
