"Cone of Silence" Possible Say Scientists

Ponca City, We Love You writes "The 'Cone of Silence,' once a staple of 1960's television shows, is now possible say scientists at Duke University who first demonstrated a working 'cloak of invisibility' that works at microwave frequencies in 2006. Such a cloak designed for audio frequencies might hide submarines in the ocean from detection by sonar or improve the acoustics of a concert hall by effectively flattening a structural beam. Although the theory used to design such acoustic devices so far isn't as general as the one used to devise the microwave cloak, the finding nonetheless paves the way for other acoustic devices. 'We've now shown that both 2-D and 3-D acoustic cloaks theoretically do exist,' says Researcher Steven Cummer. 'It opens up the door to make the physical shape of an object different from its acoustic shape.'"

      That reminds me of trying to explain "I can has cheezburger" to my hairstylist.

      While cutting my hair one day, she mentioned she loved taking pictures of her cats.

      I said "You should check out this new craze. It's called "I can has cheezburger" and you take a picture of a cat doing something, and then you put a caption on it that is clever, then you post it on the internet."

      She says "I already go to a site and upload my cat pictures."

      I say "Well, it's not really cat pictures. It kind of 'transcends' cat pictures and becomes something else. Kind of a "meta-cat picture".

      She says "....uhhhh...what?..."

      I say "I can't really explain it, you kind of have to see it. Go to this website: 'I...can...has...cheezburger... spelled with a z and no 'e'"

      She says "....uhhhh...what?...."

      I say "I'll write it down...the site is named after the first cat picture called "I can has cheezburger". Now that cheezburger cat is famous in his own right. He's called 'Happycat'."

      She says "the pictures are of cats eating cheeseburgers?"

      I say "No, just captioned cheezburger."

      She says "Ok"

      She now thinks I'm completely insane and is silent for the rest of the haircut.

  3. "Cone of Nonsense" Possible Says Teckla by Teckla · · Score: 4, Funny

    Researchers at the Teckla Institute for Scientific Advancement have determined that it's possible to have a "Cone of Nonsense" that remains stable for months, even years.

    "Take, for example, the Cone of Nonsense generated at Slashdot, an online site dedicated to News for Nerds," says Dr. Teckla, a long-time scientist at the Institute. "We've identified at least two powerful Cone of Nonsense forces there, which we've named the 'Roland Piquepaille Effect' and the 'Ponca City, We Love You Force'."

    Combine these potent forces with 'ScuttleMonkey Energy', and the result is a stable, if frightening, Cone of Nonsense.

    "We're not sure what happens if you enter this Cone of Nonsense," commented Dr. Teckla, "But we're pretty sure it drops your I.Q. by 50 points.

    I had a girlfriend once whose physical shape was AWESOME, but her acoustic shape was terrible. Believe me, you don't ever want to be in that situation. Now, the ones that are nearly spherical are easily identified from a distance, and I tend to stay away from them.
