DIY Experiment – Tricks with strips
Can you cut a paper ring with a single cut such that it forms a bigger ring? Find out about this and other tricks with the help of our young scientists Eva and Elisabeth. Can you discover all of the hidden shapes?
In this week’s science leaflet you’ll find a puzzling handcuff riddle to try with a friend. Learn more about topology and read the story of a young lady who escaped from an evil king thanks to topology!
Interview with a topology researcher
Our expert Kristóf Huszár talks about how he became a fan of mathematics. He also reveals whether it is true that topologists cannot distinguish between a donut and a coffee cup.
