Silver earrings nautilus shell
Be enchanted by the wonders of the sea as well as mathematics with these earrings in the shape of a nautilus shell - a natural phenomenon that intrigues biologists and mathematicians alike. The spiral shape of the shell is not only aesthetically stunning, but also an example of logarithmic growth in nature.
Each nautilus shell consists of a series of carefully constructed chambers (septs) separated by walls within the shell. These chambers form a logarithmic spiral, with the radius of each winding increasing by a constant factor - a growth pattern close to the famous golden ratio (ϕ ≈ 1.618), although in reality the growth ratio is often slightly lower (between 1.33 and 1.5).
The nautilus builds an average of about 30 to 38 chambers during its lifetime , each time it grows out of its old chamber and adds a new one. This mathematically elegant construction has given the shell iconic status in both art and natural science.
