The theme for 2025: Mathematics, Art, and Creativity
Every year we announce a theme to flavor the celebration, spark creativity and bring light to connections between mathematics and all sorts of fields, concepts and ideas.
The 2025 IDM theme celebrates the creativity found in mathematical discovery and art. Using mathematics in art opens doors to new ideas, beautiful and captivating creations.
We invite everyone to celebrate mathematics, art, and creativity, showcasing the harmony of logic and imagination, where numbers dance with colors, equations sculpt beauty, and ideas transcend boundaries to inspire and innovate. Creativity unites mathematics and art, fields that may seem separate, but were originally intertwined, both seeking to reveal the beauty of the universe.
