On 14 November AIMS South Africa hosted a public lecture titled “Folding Numbers – Mathematics Meets Origami,” presented by Prof. Michael Winckler from Heidelberg University. This two-part event – lecture and hands-on workshop – showcased intricate connections between the ancient Japanese art of paper folding and modern mathematics.

It attracted more than 100 people, including AIMS students, staff, visiting lecturers, industry professionals, artists, a delegation from the German Embassy in Pretoria, and retirees who value lifelong learning from Muizenberg and the surrounding communities.

Origami, derived from the Japanese words ori (fold) and kami (paper), has long been a cultural art form. However, as Prof Winckler demonstrated, its mathematical foundations have led to groundbreaking advancements in design and problem-solving. From ancient napkin folding to cutting-edge satellite technology, origami principles are shaping fields like engineering and computer science.

Prof Winckler shared fascinating insights, such as how origami helps solve complex equations, design foldable structures like solar panels, and even tackle mathematical challenges like trisecting angles, which are impossible with traditional geometry. He also showcased models ranging from delicate tessellations to rigid structures that combine artistic beauty with scientific precision.

The lecture transitioned seamlessly into a hands-on workshop, where participants had the opportunity to put theory into practice. Under Prof. Winckler’s guidance, with the support of AIMS Masters students, attendees learned foundational folding techniques and explored the principles behind creating complex origami designs.

The workshop emphasised the importance of precision and patience in folding, as participants crafted their origami models. It was an engaging experience that allowed individuals of all ages and skill levels to immerse themselves in the art form. Many participants left not only with their handcrafted models but also with a deeper appreciation for the mathematical elegance underpinning origami.

“I learned how people put in much effort to make an art with paper, sometimes it takes them six months to finish which is an example of resilience and determination. They might have failed many times but never gave up. I have learned to keep on try my best to get to the top.”

“I found the event informative and stimulating. I was happy to see such a well organised and well attended event. The fact that the audience were so diverse was very heartening.”

“Attending this has made me decide that once a month I am going to step out of my comfort zone and attend events that interest me, that I would not usually attend.”

“PLEASE hold more wonderful evenings like this. The venue is wonderful and I am super impressed with how the building looks inside, the facilities and the fact that all the top mathematical brains, from ALL over Africa can be under one roof. THANK YOU AIMS for making a difference.”

“I was deeply impressed by how well organised the event was. We were greeted at the door by very friendly and helpful students. I could hear every word and follow along with the presentation and the fact that it was well attended speaks to great organisation. I appreciated the email reminder!”

Organised by AIMS House of Science, this event was part of the ongoing heiAIMS Network for Applied Mathematics and Scientific Computing project, fostering collaboration between Heidelberg University and AIMS South Africa.
