Pattern Story

When our son brought home his interest in irrational numbers and mathematical theorems, his excitement was contagious. His knowledge far outstrips mine, but I shared his fascination with Pi as a middle schooler. It is really fun to think of numbers unfurling in space, marching out beyond imagination and light. I was inspired to plot the digits of irrational numbers using a color algorithm – my own take on a color trajectory. I wanted to engage numbers in a new way and found there was an architecture, a different kind of reveal as I painted row after row of colorful lines and squares. I found cadence in irrationality and a new correspondence with color.

Product Story

This series was inspired by my (then) grade schooler’s fascination with mathematics, and in particular irrational numbers. I wanted to better explore numbers in the only way I knew how—through paint and color. I assigned a color to each number and discovered that even irrational numbers can offer a unique cadence and pattern on these colorful notecards.

The Irrational Numbers Notecards were created in collaboration with Society for Science to celebrate their centennial anniversary. Society for Science shares the excitement of science through their award-winning magazine, Science News, and their world class science competitions.

    I love these note cards. The large size works well for longer correspondence. And the irrational number artwork is both beautiful and soothing to an accountant!
