This new IMAGINARY exhibition in The Netherlands is organized by the Dutch Platform for Mathematics, in collaboration with Dutch universities and supported by partner organisations. The exhibition runs simultaneously in Flanders, where the Flanders Platform for Mathematics is the driving force. From June 2022 and throughout the school year 2022-2023 "IMAGINARY: beauty and power of mathematics" can be visited and experienced. There will be free guided tours for school classes and other interested parties at each location. The exhibition includes numerous top-quality posters, a series of 3D objects, puzzle setups and several interactive apps that visitors can engage with via large touchscreens. Mathematics: surprisingly diverse, appealingly beautiful and stunning applications!

  • Ionica Smeets

    Ionica Smeets studied technical mathematics at Delft University of Technology and obtained her PhD in 2010 from Leiden University on a subject in number theory. She was widely known for the website "Wiskundemeisjes" (Mathematics Girls), and gradually became more and more committed to science communication. Ionica is now head of the Leiden Science Communication and Society department and enjoys training students in the master's specialization of the same name. Within science communication she investigates the gap between experts and the general public. What goes wrong when those groups communicate with each other? And what can scientists do to improve this process? Ionica also writes books, such as "Rekenen voor je leven", and regularly appears on TV shows. In this video she gives her vision of the exhibition "Imaginary".
