    The Associated Press: Cloak of invisibility takes a step forward

    By RANDOLPH E. SCHMID (AP) – 11 hours ago

    WASHINGTON — From Grimm's fairy tales to Harry Potter, the cloak of invisibility has played a major role in fiction. Now scientists have taken a small but important new step toward making it reality.

    Researchers at Germany's Karlsruhe Institute of Technology report they were able to cloak a tiny bump in a layer of gold, preventing its detection at nearly visible infrared frequencies.

    Their cloaking device also worked in three dimensions, while previously developed cloaks worked in two dimensions, lead researcher Tolga Ergin said.

    The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light, hiding the bump in the gold later beneath, the researchers reported in Thursday's online edition of the journal Science.

    Me and my profession

    As a qualified educator, and educator of the educators, I am a communications expert; understanding how and why information delivery works and doesn't work. I have experience with technology and consider myself an information-futurist. I am a dreamer!

    Now, enough of that wank and onto some more...I have been a teacher of modern English and literature, taught people the skills of learning, teaching and communicating. A can look at big and little pictures and advise on getting from point A to point B. I can read maps!

    I am an excellent facilitator, negotiator and have, on many occasions in the past, presented to small and large groups alike. I am a talker!

    My experience in commercial enterprise has helped me take a leap from the structure and politic of government back into the real world. I am a thinker!

    But I am a teacher; was a teacher of skills and knowledge, and now, like most of us, just a teacher.

    Specialties:

    Information and communication developer, reviewer and planner, advice on learning, elearning and services online. I see the past and dream the future. I can use smart and dumb tools. A sharer and a listener. A strategist and a dreamer. I can negotiate with people from all walks. I know where I am at and where you want to be. I can read maps!
