Scientists Have Apparently Figured Out How To Tie Light In Knots!?

Excerpt:

This new research demonstrates a physical application for a branch of mathematics previously considered completely abstract.

Professor Miles Padgett from Glasgow University, who led the experiments, said: "The sophisticated hologram design required for the experimental demonstration of the knotted light shows advanced optical control, which undoubtedly can be used in future laser devices".
