Well, maybe you should start with http://www-personal.umich.edu/~scheeres/conferences/AIAA-2004_1446.pdf , http://www.b612foundation.org/papers/wpdynamics.pdf etc. Most of the posts on this thread are ignorant and clueless. Don't treat everything you don't understand with scorn.

Please also see this http://neo.jpl.nasa.gov/torino_scale1.html

THE TORINO IMPACT HAZARD SCALE
No Hazard
(White Zone)
0
        The likelihood of a collision is zero, or is so low as to be effectively zero. Also applies to small objects such as meteors and bodies that burn up in the atmosphere as well as infrequent meteorite falls that rarely cause damage.

Actually there are many objects we are monitoring, please see http://neo.jpl.nasa.gov/risk/.
This object's impact probability is 7.1*10E-4. That's 0.00071, and not 1/1000.
The Torino Scale Color says white, which means impact is almost impossible.
Most of the times even if the probability is increased, it is quickly reduced after some investigation.
Currently the most dangerous object is 2007 VK184 (2048-2057) which gets green rating. This article is nothing more than sensationalist and stupid.

More like 72 years. NASA says that they would need to start actual diversion operations 100 years in advance, which leaves 72 years to figure it out.

Cars have been turning well for decades now. It isn't rocket science anymore. The real improvements in cars have come in the field of safety, nothing much has changes elsewhere.. And electric cars aren't exactly new, they're just popular now cause we have this environment/oil problem.

What matters is what you leverage it for, not how many use it- China has like 1.3 billion people right. And still it hasn't produced the great scientists, inventors, or respected companies. They are implementers and consumers, not innovators and are treated as such

Do you per chance walk around in an "I'm with stupid" t-shirt?

Forget about fair moderation from Slashdot nowadays. Moderation has gone to the dogs with mass idiots joining this site. My previous account got modded down so severely to Karma terrible that my posts could not be read by anyone unless they browsed at -1. This new account has bad karma too. I now plan on trying a new system, view at 0 and mod up all on my friends list to +5,

This is flamebait? This goes to show that this moderation system sucks.

Have you realized how Apple is making these birthday gifts more and more expensive? First the ipod, then ipod touch/ iphones, now ipads that go all the way to $900.. jeez

These are the use cases that i see for an ipad
1. When you need long battery life
2. Anyone who is humiliated carrying a sub $400 full fledged computer, anyone with acute herd mentality i.e "must have this popular item to be cool" etc

Any motor vehicle doing decent speed would require licenses and such, unless it's the 2mph kind that old people use.

Unless your trike is as safe as a car, you might as well buy a motorcycle.. But the trike wouldn't be as sexy as a car or a bike so it should be fine as you'd prolly be alone anyway
