This year we were lucky enough to see the Imaginary exhibition in Barcelona. It's an interactive mathematics exhibition that inspires the imagination with beautiful images. And what is more exciting it allows anyone to step into the world of maths! You can create and play with beautiful mathematical surfaces using the surfer software and explore the symmetry of tiling patterns with Ornamente.
We went along to the Imaginary Barcelona conference, which brought together the Imaginary team, from the Mathematical Research Institute Oberwolfach, and everyone from RSME who brought the exhibition to twelve cities throughout Spain.
You can read our postcard from Barcelona or enjoy our picture podcast on the right.
The photos in this podcast are by Rachel Thomas for Plus and by Sebastian Xambo for Imaginary and the images of mathematical surfaces are by Herwig Hauser and Rachel Thomas using Surfer. For more information on Imaginary visit http://www.imaginary.org and you can read more on maths and art on Plus.
