+ - Asteroid risk greatly overestimated by almost everyone

It’s why so many of us are so eager to play the lottery, and simultaneously why we’re catastrophically afraid of ebola and plane crashes, when we’re far more likely to die from something mundane, like getting hit by a truck. One of the examples where science and this type of fear-based fallacy intersect is the science of asteroid strikes. With all we know about asteroids today, here's the actual risk to humanity, and it's much lower than anyone cares to admit.

While this is true, frankly I would argue that "Mother Nature" does more damage to the road than semis. And we can't really tax her.

Roads are a community resource that we all use in one way or another. The guy on the bike who says, "I don't damage the road so I shouldn't have to pay" neglects to consider the fact that his fancy super-light carbon-fiber bike showed up at his local bike shop on the back of semi. He whines about how crappy the road is along the right-hand side due to frost heaves but isn't willing to pony-up any money to actually get it fixed because, why should he have to pay? He didn't do the damage.

I gotta agree.

Way back when in my old mainframe days, I remember one of the most popular things was "chat programs." The people at the computer center thought this was a complete waste of resources. My argument was that it got people to use the computer as a tool to chat with other people. Once you got them thinking in that direction, it was easier to turn them on to other capabilities.

I remember my old girlfriend being surprised that she could use this computer thing to write papers far more conveniently than using the typewriter.

So to me, the answer is "tools." I'm not into the whole "Computer Aided Education" thing--I'm not sure it's any better than a book or film-strip or anything like that. So the idea would be to teach people the tools--it really doesn't matter which ones--that they can use to be more efficient students. Back in the olden days, that would be things like text-processors (anyone else remember RUNOFF?). Today, it would be things like word-processors, maybe some simple spreadsheets and graphics programs, and techniques for searching the web.

Well, close...

FTFA:

For example, the space plane is carrying a type of ion engine called a Hall thruster on OTV-4, Air Force officials said. [...] “A more efficient on-orbit thruster capability is huge,” Maj. Gen. Tom Masiello, commander of the Air Force Research Laboratory in Ohio, said in a statement. “Less fuel burn lowers the cost to get up there, plus it enhances spacecraft operational flexibility, survivability and longevity.”

I gotta admit, I'm curious why the NASA mission flying on there couldn't have been done on ISS...
