After a long winter, spring is a miracle that comes at you fast. This time Sophie and Fannie turn their heads towards the trees to investigate the natural laws that govern not just trees, but people, animals, and even the universe. We take a walk around Martha Stewart's farm with her long-time arborist Ralph Robbins of SavATree, and get a lesson in the Fibonacci sequence from Gregory W. Brown. Plus, we sit down with Kodomo, our frequent music-collaborator, to hear how the golden ratio found its way into his songs. Then we visit the Shanti Bithi Nursery in Stamford, Connecticut to see how the Rocherolle family carries on the ancient art of Bonsai.
