In Salon de Mathematiques in Paris, which is held each year, we were lucky to meet association Imaginary. Volunteers from Imaginary told us the story about this growing community of people and explained about the history of its creation.
10 years ago in Germany Imaginary did the first exhibition with mathematical images. The exhibition was really successful and the association also decided to make a very particular gesture, they also made images from the exhibition to be open for people, who are interested to participate or to organise the next imaginary exhibition at their city.
This way the community started to grow. Learn more at the website imaginary.org
