Each equipped with $48,000 worth of GPS components, electronic maps, and wearable computers, troops of the Army's 5th Brigade, 2nd Infantry Division are heading to Afghanistan as part of the resurrected Land Warrior program. The Army is hoping the revised, eight-pound set of gear will be more beneficial than when the $500 million program was canceled in 2006.
As a Vietnam veteran, my prayers go out to the soldiers who were chosen to go downrange and field test this fancy electronic gear in a live-fire environment. Lord knows we had to test enough drek in the 9th Inf Div, most of which wasn't adequately waterproofed... RLTW Class #9-67
There's no denying that Google Earth has changed the way we view our planet's landscape. With a click of your mouse, you can "fly" around your own neighborhood, zooming in from space to street level. Curious about volcanoes? Dart over to the east coast of the Big Island of Hawaii and at times you can actually see the steam where lava enters the ocean. You can even explore the whitewater rapids on the Colorado River in the Grand Canyon. But it was Google Earth's "Ocean" layer that recently caused quite a stir among 3D geeks.
Disclaimer: I'm a Santorini advocate for the location of Atlantis. And I've never been in the Navy, but I once worked for a seismic data brokerage company here in Houston and what the tracks look like to me (especially considering the scale) are the result of a seismic exploration survey. The way they work is that the ships tow long lines of detecters behind the ship while noisemakers - usually either explosives or compressed air "bubblers" - which are bounced off of the sea floor to create seismic waves which are picked up by the detecters. After each run (let's say from east to west), the ship reels in the detecter array, makes a large turn, deploys the array and heads in the opposite direction. After completing the east-west runs, the ship completes the 90 degree grid by running north to south. This gives enough information to make a computerized 3D image of the subsurface geology. Then, if a certain area warrants more investigation, the ship makes a more detailed examination of the area in question. But there are indeed anomalies off shore from the Bahamas to Japan to India to the eastern Med and the Black Sea which need more investigation. And has anyone used Google Earth to take a look at Mt Atarat?
As part of PopSci's "Future of the Environment" special, we commissioned a modern, eco-themed take on the classic videogame "Frogger." In our version, called "The Walker," players have to catch various forms of alternatively fueled vehicles to help them cross a busy highway and make it to school on time.
I'm a pedestrian. About four years ago my cataracts got so bad that I sold my car out of fear that I'd cause an accident. Now, the eyes are in good shape, but I'm still carless. Forget the "Walker" game and try spending a couple of weeks walking or taking public transportation everywhere. Fortunately, there's a supermarket about a quarter mile away, but I have to cross a busy 4 lane street coming and going... I feel like the original "Frogger" game!
