The poster for IDM 2026 is here! It is based on this year’s theme, Mathematics and Hope, and features a circular rosette pattern.
The poster is available in several languages and comes in two versions: a full-color design and a black-and-white version that you can color yourself.

Curious about how machine learning works and how to teach it?
IMAGINARY created a free and open-source online course for (prospective) teachers. It introduces two key topics of AI in a playful way: artificial neural networks and reinforcement learning.
A special highlight in this course are our “explorables”. They are small interactive games that run directly in your browser, require no extra software, and can be used in your own lessons.
The course is designed especially for STEM teachers and teachers in training (with a focus on computer science and mathematics), but it’s also suitable for workshops, project days, study groups, students, parents, and anyone interested in learning more about machine learning.

MaRDI is a Germany-wide initiative to address challenges in mathematical research. It is aimed mainly at mathematicians to change how we do mathematics using FAIR (Findable, Accessible, Interoperable, and Reusable) research data. This way, it fits very well with our own open-source philosophy.
IMAGINARY actively participates in this initiative by assisting in communicating and...Read more

March 14 is already known as Pi Day and is celebrated in many countries worldwide. It is named after the important number π, the ratio between the circumference and diameter of a circle, and approximately equal to 3.14. The International Day of Mathematics (IDM) celebration expands Pi Day to include the whole spectrum of mathematics. Mathematical language and reasoning are accessible to everyone. This year, the...Read more
