I've thought of puzzles like this being like search trees. It seems that we navigate possible solutions like a depth-first search, because one thought leads to the next, leads to the next... Smarter people can search deeper, but then they can take longer to find the answer to puzzles like this because they follow wrong paths longer. The solution: mentally switch to a breadth-first search. Try to throw you your last thought and come up with a completely fresh approach. Then do it again. After you have a few different approaches, then think about extending them.
What is the typical frequency? (i.e. 1x per galaxy per 100k years) What is a typical duration? How close would you have to be to one to receive a lethal radiation dose?
A lot of people don't need to find gratification in their work. Many people find a boring job that pays union wages, and find their satisfaction in their family and friends.
We're on the way to replacing these jobs with robots, and very small shell scripts. This will lead to a overall higher standard of living. Unfortunately, there are cries of "OMG, we're losing jobs!" from the people who are directly affected. Not everyone likes to continually educate themselves, spending time away from people they love.
Or it would simply get sliced in half. Or it could bounce. In any case, its unlikely that the cable would absorb the full kenetic energy of the object.
You bring up an interesting point about "legal abortion and religious coersion". I think that 80% of the people who identify pro-choice in a given survey aren't pro-abortion per se. To put it another way, I don't think that anyone, when they imagine their vision of utopia, has abortion included in it.
It seems to me that a pro-choice vote is mostly a "Fuck off you stupid religious nuts trying to run my life!" vote, and perhaps has little to do with the actual issue of abortion itself.

Diamond Nanotubes Created

I happen to love how chemistry has been rebranded as nanotechnology. My favorite example is stain-resistant Dockers.
Congratulations. You can do vapor deposition of diamonds, and you can do vapor deposition of carbon nanotubes. So can everyone else. You can do them both at the same time? Interesting. Too bad you can't control the process beyond the ratio of nanotube to diamond.
What about average tube length? Alignment? Bonding with the diamond? Anything beyond what you'd get if you mixed extremely fine diamond powder and nanotube powder, mixed and compressed? Guess not.
However "Ultrananocrystalline(tm)" sure sounds cool. Maybe the innovation is in the buzzword.
We all know what hyperlinking is. Hotlinking is different.
Hotlinking is the practice of taking someone else's resources, typically images, sounds, flash files, etc, and displaying them inline in your own HTML page. This causes losses to the creator because they still have to pay for the bandwidth of serving the file, but reap no benefits. For example, the creator may have advertising around the page with the Flash game that never gets seen.
Hotlinking is generally seen as very bad form among web developers.
From Wikipedia: "[Carbon] also has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly 10 million known compounds."
Not only is it able to chain, and thereby make organic compounds, DNA, nanofiber, but the bonds it forms can be very weak or strong. So yeah, carbon has unique chemical properties, its cheap, and (too) widely available.
As a side question, who thinks that as all of the advanced carbon materials become readily available over the next 50 years, and demand increases, that we may have found our solution to global warming? We'll scrub CO2 from the atmosphere to build our carbon products!
I don't think China is as big of a threat to the western world as you think. China could potentially pose a threat in three ways: militarily, though economic superiority, and through mass consumption of resources.
Militarily, I doubt that there will be any more superpower vs. superpower "hot" wars, due to the certainty of nuclear retaliation. The most China could do without risking nuclear war is conquer small neighboring states of no world economic value.
With respect to economics, despite their large population, they will never be economically dominant without being a free society. Free societies have better educated and more motivated populations. Also, when a totaliatarian governments tax the people for measures that serve only the goverment (lavish palaces, military buildup), they only take capital out of the economy. If China is to be the dominant player in the world economy, they will have to become free first, which is obviously welcome.
With respect to resource consumption, they will definitely be competing for scarse resources. This is the realistic cause for concern. On the other hand, people are remarkably adaptable and resourceful. I think we'll adjust fine, albeit with some growing pains.
While $50 / month for an average cell phone plan is affordable, it's still a lot more than I'd pay for VOIP service bundled on my hypothetical Google nationwide WiMax plan. I'd switch.

One also might consider this evidence towards contamination.
One of the reasons evolutionary biologists believe that everything evolved from a single organism in the distant past is that all amino acids, etc are left-handed.
What if we found life on Mars, and all of its chiral molecules were right-handed. I think that you would have to conclude that it was an independant emergence of life.
This would be extremely strong evidence. There would be no one going "OMG, we contaminated our samples. It's all BS!!" We'd have to consider that spontaneous generation of life is not all that uncommon. Maybe this would cause a widespread rethinking of our place in the universe.
BTW, At current exchange rates, this rule was bought at a price of 108 standard tons of gold. I was hoping to see how many Libraries of Congress that would fill, but that's only 181 cu. ft. Kinda disappointing really.
While Ruby may be a good choice for a 1st language (though I'd teach either python or java), DO NOT teach Rails.
Besides the obvious concerns of having to teach HTML at the same time, Ruby on Rails uses *way* too much magic for beginning programmers. There are all sorts of domain specific shortcuts that Rails uses. How are you supposed to teach iteration when the Rails uses something like collection_select?
You hopefully learned a little bit about how to be a senior programmer in the real world. No one was there to hold your hand through the tough parts, you had to make architectural decisions with somewhat lasting ramifications, you had to deal with tough business realities.
This real-world experience will help you in the long run.

Sometimes, one has to wonder if our shortsightedness even has limits.
* Increasing consumption as we run out of oil.
* No legitimate contingincy plan in case of asteroid colision.
* Massive individual credit card debt
and the list goes on... (but feel free to add to it; I want to see what I forgot.)
We just called this "chemistry."
