Publisher's Synopsis
What makes the tiny snail shell so beautiful? Why does that shape occur in nature over and over again-in rushing rivers, in a flower bud, even inside your ear?
With simplicity and grace, Sidman and Krommes not only reveal the many spirals in nature-from fiddleheads to elephant tusks, from crashing waves to spiraling galaxies-but also celebrate the beauty and usefulness of this fascinating shape.
