Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists ...

Roughly speaking, the spiral of the chambered nautilus triples in radius with each full turn whereas a golden-ratio spiral grows by a factor of about 6.85 per full turn. The measured ratios ranged ...

In three dimensions, the spirals and cauliflower-like crimps on the shell’s interior come to life. Virtual models of the septa, used to create the 3D prints, are an iridescent fever dream.

Nautilus shells have come a long way since the days they were hailed as manifestations of the Fibonacci sequence in seashells. While they may resemble a golden spiral, scientists have since debunked ...

The optical rotatum grows in a spiral shape that is also present in the shell of a nautilus (a type of mollusk), sunflower seeds, and branches of trees. “That was one of the unexpected highlights of ...

“here is a pic of my tattoo based on the golden spiral and a nautilus shell. i’ve wanted to get this done since high school and finally got up the courage to take the plunge earlier this year ...

A relative of squid and octopi, the chambered nautilus grows to about 8 inches long, with a spiral shell and about 90 tentacles it uses to catch prey. It’s often called a “living fossil” because of ...

An animal so rare that only two people are thought to have ever seen it until now has been photographed and briefly captured in the South Pacific. The creature is a species of nautilus, a group of ...
