I'm a professor of mathematics moonlighting as a temari ball crafter. My temari style is called "sosaku" (creative) temari. I enjoy exploring intersections of mathematics and arts from a variety of perspectives, especially the spherical perspective. I'm also passionate about promoting the beauty of mathematics to the public to generate positive social change.
Inspired by the Pythagorean Tree in a plane, I stitched the Sakura Pythagorean Tree on a temari ball of circumference 58 cm. This Pythagorean tree has order five and begins with a square of side 5 cm. Upon the first square I constructed two squares to depict the Pythagorean theorem, and from there I continued recursively. Each square is scaled down by a linear factor of about 0.7.
