Imagine how you might pass a straight metal rod through a curved hole. How does that work if neither bends? Is it impossible? This demonstration at the Science Museum in Valencia, Spain shows that it’s absolutely possible with some creative thinking: motion changing where objects intersect over time. A simple but interesting demo… we want to build our own.
In the archives: more spinning and more geometry, including a few Eames films from Mathematica: A World of Numbers… and Beyond.
