Physicists Make a Mobius Strip From Beams of Light

rossgneumann writes: A group of physicists has successfully manipulated beams of laser light into an optical mobius strip (abstract). The shape, a classic mindbender all but nonexistent in nature, has never before been seen in such an immaterial form.

      In mathematics, some actually take it as an honor to lose the capital in the name of something, as it means that their contribution has gone from being simply being something named after them to something that is so important and fundamental in the subject that it may as well be an adjective.

      An example is that of an abelian group in group theory. There are many books that simply leave it as a lowercase, but it was named after Abel.

    to illuminate Mars! Where it will resolve the illusion
    of dry valleys and magnificent desolation
    into a cheerful reality of watery canals,
    tall spires of intelligent, unknown purpose,

    spreading outward from the poles and oars
    of longboats and trailing garlands of flowers.
