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.

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
