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 produced in the lab, and the researchers believe that they could provide valuable insights into the angular momentum of light. On a more practical note, they could also be used in imaging and data-storage applications…………
