Mathematicians Design Invisible Tunnel
New calculations show how to make an electromagnetic "wormhole" — a tube that is invisible from the sides but allows light to shine down the center. The practical applications are a ways off, as even the design of a spherical invisibility cloak has not advanced beyond working (in theory) for a single wavelength of visible light.
anyway, it seems to work on the website.
Not to be a party pooper, but is there really any application for this tunnel? You can't see it, you can't see out of it, and you need to build it so it can only go to places you can already go.
In NJ we already have tunnels that seem to do nothing. We call them the Holland Tunnel & Lincoln Tunnel.
"advenced"? "are a ways of"? That futuristic language must be from the other side of the wormhole!
If anyone is interested, I found a photo:
this is a good application for the army. a series of tunnels and your moving trucks and cargo without the enemy seeing them. all they would know is that you have the tunnels but would'nt know exactly what your moving.
I don't quite see how anyone can claim they designed such a thing. It is sort of like saying Klein designed a bottle that holds everything on the outside on the inside. Of course a Klein Bottle is impossible to construct, sure it's an interesting mathematical idea but it's not anything you can make in reality, so it's senseless to say it's been designed. Let's just say it's been imagined.
... hence the "quotes"
Here's to finally giving Bush his exit strategy in November
Bah.. I just checked out ThinkGeek, and [b]still[/b] no 1:12 working model of a Stargate..
:P
I mean, what's the use of this technology if they're not putting it to good use
Scully: Should we arrest David Copperfield?
Mulder: Yes we should, but not for this.
hell, yeah. now we'll be able to download pr0n without others seeing.
Do not. Touch. Down.
Joebert ! you're late !
No I'm not sir, I got an early start cleaning up inside the tube.
Wanna fight ? Bend over, stick your head up your ass, and fight for air.

I know I shouldn't reply to sigs, but I didn't read that as a sig at first. I was going to agree that given his current situation, an invisible wormhole would present Bush with an attractive exit strategy indeed.
Ideally, one would be able to invisibly travel through the wormhole and emerge from it wearing a flight suit.
Math guy: "Look! We've shown how to make wormholes, with math!"
Me: "You forgot to carry the 1."
Math guy: "Damn!"
Democrats or Republicans. They are both taking us to the same place and they are not afraid of us anymore.
Wow, I just took a flashlight and shined it straight down in front of me and I didn't see the beam in the air at all. I better see if there's one of these invisible tunnels in front of me.
Oh, wait, that's what light already does.
That's the dumbest fucking idea I've heard since I've been at Microsoft.
A biologist, a physicist, and a mathematician are sitting in an outdoor cafe. They watch two people go into a building across the street. Shortly thereafter, three people come out.
"Hmm," says the biologist. "It looks like they reproduced."
"Nah," says the physicist. "There was obviously error in our initial measurement."
The mathematician looks up from his coffee. "Who cares? If another person goes in, it'll be empty."
There are a huge number of yeast infections in this county. Probably because we're downriver from the bread factory.
Scientists develop invisible, weightless clothing that is so thin you can't feel it. One of their first customers has been the King of England, but orders have also been placed by the President and hundreds of middle aged men hoping to impress their wives this Mother's Day.

Yet, if I step into the middle of th beam, you'll see me. Not so with this tunnel.
