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 ...

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 ...

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 ...

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 ...

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 ...
