What the U.S. Army has to do with Sarah Palin, the Terminator and Men in Black.
Holograms may be the stuff of CNN laughability these days, but it turns out the U.S. Army is working hard on the real stuff. According to Dr. John Parmentola, Director of Research and Laboratory Management with the Army’s science and technology office, they are “making science fiction into reality” using quantum computing.
Here’s the gist: There’s a special kind of photons that don’t bounce off of objects but off of other photons, which have bounced off of objects themselves. This causes the object to be reflected in the second set of photons, creating a “ghost” image. Hence, the technique name: “Quantum Ghost Imaging.”
The Army hopes to use it in confusing the enemy with objects rendered through smoke and clouds. And we thought ghost soldiers were the stuff of Hollywood blockbusters.
The interesting part is that the military has been dabbling in quantum mechanics, neuroscience and robotics a lot lately, making nice with scientists and major research universities so they can grab revolutionary technologies before the general public.
Remember the Boston Dynamics Big Dog that shot straight to the YouTube top a few months ago? The technology was actually developed years ago and its possible military applications were first discussed by roboticist Rodney Brooks in his TED talk back in 2003. They’ve also dabbled in stem cell research for “growing back” body parts, turned to neuroscience for memory-erasing amnesia beams, and looked into controlling robots with nothing but thought.
Creeped out yet? You should be — it’s scary, Big-Brother-meets-Terminator stuff. But it’s also exciting to observe the mind-blowing scientific and technological progress of our day. That, and we loved the amnesia beam in Men In Black.
How to stop global warming and hackers with the flip of a light switch.
THE REAL IDEA LIGHT BULB
LED lights have spent some time in the spotlight lately — be it as eco alternatives to Christmas lights or as cool little sidekicks in wow-projects like the Chronophage Clock. Turns out, however, that they could be the springboard for the next big leap in wireless technology.
Engineers at Boston University have just launched Smart Lighting, a program using low-power LED’s to develop the next generation of data communications and network technology — basically, making LED light the equivalent of a WiFi hot spot. And it would all be done over existing power lines with low power consumption, high reliability and no electromagnetic interference.
This technology would enable you to come home, flip a light switch, and have your iPod, thermostat, TiVo, Sirius and Wii instantly start communicating with you. No wires, no plugs, no routers.
The project is taking advantage of our inevitable switch from incandescent to CFL to LED light bulbs over the next few years as we try to, you know, not drown in the melting ice caps. Once enough LED’s are in place, they’d provide the infrastructure for this next-generation communication infrastructure.
Plus, since white light can’t penetrate opaque surfaces like walls, the technology would be much more secure than today’s radio-frequency-based WiFi — this means no “eavesdroppers,” no hackers, no pesky neighbors leeching onto your already feeble open wireless.
The technology relies on LED’s ability to be rapidly switched on and off with no detection by the human eye. Because data transmission comes down to patterns of 1′s and 0′s, flickering an LED light in such patterns won’t cause any noticeable change in room lighting.
We’re anxious to see where all this goes — with today’s increasing fragmentation of technology, it seems like more is invested in developing things to mediate the effects of other things (like your $300 noise-cancellation earphones to silence your roommate’s $1,000 Bose, which he uses to unwind after 15 hours in front of his $2,500 MacBook Pro), so we’re glad to see technology that focuses on cross-functionality and efficiency, utilizing what’s already there to minimize peripherals and maximize data communication.
Inspired by the ever-amusing Indexed blog — if you’re not already familiar, we strongly suggest you fix that cultural mistake ASAP.
I’M A MAC, AND I’M A MAC POSING AS A PC
The horror! The scandal! You know those annoying new “PC Pride” TV spots for Microsoft that attempted to shove the Seinfeld fiasco under the carpet? Well, an overzealous conspiracy theorist decided to look at the EXIF information of the campaign photos sent to the media — that’s the little piece of file information that shows what program the file was created in.
Guess what — those Microsoft ads were made on…gasp…a Mac. And if you think Microsoft and Crispin, their ad agency, have the relationship equivalent of a Catholic priest caught with his pants down at a gay bar, it gets worse. Turns out, Dell’s agency, Enfatico, did the exact same thing with their client’s campaign. Except in their case, those Macs were actually bought on the Dell dollar.
And just when we thought no one could out-whore-out the ever-irreverent Improv Everywhere…who actually revered quite quickly at the sight of corporate bling.
Speaking of Seinfeld, here’s something that sounds like one of Kramer’s ideas but is, in fact, completely real:
One of our heroes, brilliant physicist Stephen Hawking, has just unveiled the world’s strangest clock. Called
Chronophage, which means “time-eater,” the beastly time-keeper cost $2 million and was developed over 5 years in Cambridge’s Corpus Christi College by Dr. John Taylor, a renowned inventor and horologist.
Its shtick: It has no hands — time is displayed by a series of blue LED lights illuminating the 24-carat gold surface through various slits and lenses. The design itself was inspired by the work of legendary innovator John Harrison, who came up with the “grasshopper escapement” mechanism almost 300 years ago.
The clock is only accurate every five minutes, but is wired up to an electric motor that will keep it running for the next 25 years.
We’re fascinated by the idea of a device that captures the relativity of time and how its passage mercilessly eats away at our lives. That, and we like shiny things.
On the cool-LED-stuff note, we’re obsessed with chronophage art collective PIKA PIKA. They make abstract animation using LED flashlights, which “draw” an image by tracing its outline over and over. Their movement is recorded in a series of photographs using long exposures, which are then spliced together into an animated sequence.
In 2005, the team was invited to a conference, where they presented the back-end of how the animation worked. They noticed that the audience of people interested in the concept was incredibly diverse, so they came up with a way to make the animation more interactive and inclusive, recruiting audience members in its production.
Today, PIKA PIKA films are made by that audience: Each person gets a flashlight and becomes a part of the animation. The films have since traveled the world and won various awards across a number of art and film festivals.
From one cool audience-made light-employing video to another: After Radiohead’s In Rainbows fan-made video contest, a Goldfrapp fan got inspired to animate the track “Lovely Head” from their first album.
It’s essentially a visualization of the sound data, with the lyrics superimposed, producing the visual equivalent of what we’d imagine goes on in one’s brain when listening to the track on psychedelic drugs.
It was made through a process that’s way over our head, which makes us dig it all the more. It also reminds us of binary data sculptor Paul Prudence his video stream data visualizations.
And since we’re getting into things way over our head, here’s something that blows everything else out of the water. Or, as it just so happens, out of the oil.
Scientists have developed a new strain of that same pant-pooping E. coli bacterium that can make butanediol (BDO), the material used in stuff like spandex, car bumpers and plastic cups, from scratch. Which basically means they can make plastic without using oil or natural gas, taking a huge energy load off the current plastic production methods.
That’s what we call research-grant-justifying progress. (Unlike, say, the one that measured methane emissions from farting cows.)
