Having a plan to deal with an asteroid/comet strike is more like having an emergency parachute. It's FAR better to have one and not need it, than need one and not have it.

That is probably a good allegory for both sides of the argument. After all, while technically true, how many people do you see carrying emergency parachutes onto their commercial airline flights, and how much good do you think it will do them if something does go pear shaped?

That’s why many schools now do the “In-School Suspension”. Sit in the principals’ office and work all day on the mounds of homework the teachers send down. Not quite as much fun as the vacation format.

I happened to get in school suspension when I was in school 30 years ago. Sat in a classroom with all the other trouble makers and was handed a sheet where all my teachers had written my work load on it. Only then did I realize how little I was actually doing in high school. Each day, only half the classes had anything of substance written for them, including homework, and I was done with that by 10 AM. I spent the rest of the day reading books for English "extra credit" or drawing for art "extra credit" as written on the sheet by my teachers. Since I was an honor student in a class of actual trouble makers, the I got to watch them act up and get into more trouble and never got into any myself, which was all quite entertaining. The only real drag was lunch where we ate in the half hour between everybody else's lunch and couldn't speak a word. If I could have had my normal lunch with friends, I would have seriously contemplated getting into more trouble on purpose so I could get more in school suspension.

I can see how one could say that Phobos and Deimos, like our Moon, have extremely regular orbital distances, but given that the science that has stated that our Moon was caused by an impactor is still itself being both refined and challenged, I wonder if it's a little premature to conclude that based on orbital characteristics alone the two Martian moons derived from the same sort of event as our Moon. After all, many of the planets have orbits that are very near circular, but we do not interpret their existence in a similar fashion.

The impactor theory for the origin of the moon is being refined, but AFAIK, it really hasn't been challenged seriously since the early 90's. Before that there were many competing theories for the origin of the moon from forming at the same time as the earth, captured by there earth, formed from impact, and a few others. Meanwhile there are various criteria such scenarios must meet dealing with angular velocity of the moon, composition, etc. In the early 90's computer modeling got to the point that they could do such for impactor theory and resulted with a model of an impact of another body of similar composition that would collide with the proto-Earth, split off a glob that would become the moon while leaving it's own iron core to explain the Earth's relative large one. At that point, while not perfect, the impactor theory was basically doing better over all in the criteria than the other options. I remember seeing the presentation and video of the computer simulation while an undergrad in physics in the early 90's. I've been keeping up with the subject when I see it, and it has been modified, mainly that two moons were formed and then they recombined in a rather low energy collision to form the moon. I have not heard any serious competition by the other theories since then.

The real minimum wage is always 0. I work in Seattle, where they recently did this. Entry level places where I live (not in Seattle), where the minimum wage is $10/hour, all have help wanted signs out. In downtown Seattle, however there was a wave of restaurant closings, and I don't see help wanted signs anywhere. Could be other causes for the difference, of course, maybe it's something else - but it's not a promising sign for teens looking for that first job.

You must be talking about a different Seattle than the one I live in. I'm seeing new restaurants opening weekly where I am, Capitol Hill, and haven't heard of any large closings in downtown. Von's closed, but that was way before the minimum wage move.

Consumption ... drives the economy.

Wrong. You can't consume what hasn't been produced. Production comes first; production is fundamental.

Canada pay an average of about half as much in taxes (scaled to their income), for the same quality and the same service.

From what I've heard about medicine in Canada from locals, this is laughably untrue. Only someone who has never had more than a minor boo-boo could claim the service is the same.

True. All the people I know in Canada, especially the ones with children, say it's much better than the US.

I love my cheap little Apple TV and will probably upgrade it to the next model when that comes out.

Same here. I don't see why they don't do with it what they did with the iPod and just add the TV features they were looking at to it. Add a small camera and give it messenger and FaceTime. Feature creep would make the next version more desirable and keep it ahead of other rivals without having to deal with the actual TV part.

Comment: Re:How would nukes exert force on an asteroid? (Score 2) 148

In atmosphere, nukes produce blast because of high energy x-rays igniting atmosphere. This won't happen in space.

So how would letting off a nuke near or on an asteroid produce reaction and change the course of the asteroid?

Basically, the x-rays will ignite the surface of the asteroid instead. If the material in the asteroid is sub-optimal for this purpose, there have been designs of turning a nuclear bomb into a kinetic weapon that should work in this regard. Basically the bomb sits in an x-ray reflective shell, and when the bomb explodes, the x-rays bounce around the shell before the exploded bits of the bomb destroy it and exit an aperture. At the end of the aperture is a large, dense block of x-ray absorbing material. This material is vaporized by the x-rays and is all traveling in a similar direction as the x-rays were all going in that general direction. This plasma moving at relativistic speeds then slams into the target like a nuclear shot gun blast. IIRC, this design was built for using nuclear bombs against space ships and it was estimated that it could direct 95% of the energy of the bomb at the intended target.

Using a Kueurig is sort of like using a rental one person self driving car instead of just buying a normal car, except you still have to park it someplace and use special, throwaway gas tanks. Now they are talking about developing the equivalent in trucks and planes for when you need them.

There is a course in men's studies it is called HISTORY.

History is gender neutral.

Not really. For most of history, women, and non-whites in the Western world, were prevented from participating and even when they did often had their achievements ignored or claimed by those in power, i.e. men. Claiming that history is gender neutral is a bit like claiming that the South, pre and post Civil War, has been race neutral.

This goes into why there are women's and other 'person's studies'. From my discussions with my friends that are sociology professors and the like, when discussing things like sexism and racism academically, the critical aspect of such is who holds the power in the relationship. To put it very simply, racism in such discussions are not just the case of one race/sex treating another race/sex differently, but one race/sex having power over the other race/sex in society and using it to dominate.
