Optically Getting To The Same Side: How To Generating Möbius Strips Of Light

A collaboration of researchers have experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light's electromagnetic field to assume this peculiar shape. Möbius strips are easy to create, of course. Millions of school children do it in classrooms every year by taking a strip of paper, twisting it once and joining up the ends. That's it, you have created a Möbius strip: a three dimensional structure that has only one side. But finding Möbius strips occurring naturally is another issue. read more
