Twisted Physics: Scientists Create Light Knots

• LiveScience
Like your shoelaces or electrical cords, light can get twisted into knots. Now, scientists have used a computer-controlled hologram and theoretical physics to turn a light beam into pretzel-like shapes.

The twisted feat not only led to some pretty cool images, but the results have implications for future laser devices, the researchers say.
