The optical rotatum's logarithmic spiral follows a pattern found often in nature, including nautilus shells. Credit: Capasso Lab / Harvard SEAS The optical rotatum's logarithmic spiral follows a ...
A logarithmic spiral with a diameter of 500 μm, approximately half the diameter of a sewing needle. Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led ...
Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...
Gael Mariani and Martin Scott perpetuate a series of myths in their letter about Fibonacci numbers in nature (3 September, p 19). It is true that the Fibonacci numbers are associated with a particular ...
As Hurricane Isabel churned toward his office in Baltimore yesterday, astrophysicist Mario Livio pondered the curious similarity between the storm’s shape and that of our Milky Way Galaxy. In fact, ...
Discoveries of new overarching rules or “laws” in nature are very rare. Surprisingly, my colleagues and I have found a new rule of biological growth that explains unexpected similarities in sharp ...
Consider the wheel. Round. Dependable. Boring. Hasn’t been redesigned in centuries. Positively Neolithic. Now consider the spiral. Eccentric. Open-ended. Captivating. Native Americans carved spirals ...
We're used to seeing spiral galaxies in deep space, but other types of outer-space spirals are positively spooky. Astronomers say that this whirligig, more than 3,000 light-years away in the ...

Light that spirals like a nautilus shell
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 in ...
