This is important work, which compliments terrestial geomagnetic measurements and space based observations.

The earth's magnetic field results from a planetary dynamo. Magnetic field lines get frozen into the electrically conductive fluid core. Then, differential motions in the fluid causes the magnetic field to get twisted up -- it's no longer is the simple dipole (like those bar magnets that you played with as a kid). Instead, the earth's magnetic field develops high order moments (sorta like bumps and dips). These shapes evolve as the conductive core moves. Eventually, the magnetic field gets so tangled up, that it unravels. At that time, the earth's field reverses. These magnetic field reversals show up in the geologic record ... every 10,000 to 100,000 years, there's a flipover.

Measurements like the ESA Swarm satellite give us a handle on the evoloution of the Earth's magnetic field, as well as showing how that field interacts with the magnetic and particle environment of the solar wind.

(disclaimer - most of what I just posted is from a terrific graduate class that I took at the Lunar & Planetary Labs way back in 1979, and when I worked with Charles Sonett, who studied the solar wind. Likely, much of this is way out of date!)

Remember when we had a Debian system on the biosciences mission? They scrubbed the whole mission after they were already in space due to a fuel-cell issue that I think turned out to be a faulty sensor, and flew the entire mission a second time.

Consider yourself lucky, then, and pray that it lasts. The people around you are not made of such strong stuff, and I can't be sure that you are either.

It actually is a bit different for the Republicans, in that they are caught in an internal party schism of a scale we've not seen on either side since desegregation, if even then. It's difficult for the less right to look good to the more right, undirected pushing against the Democrats is one of the few ways they have to do it.

Do not forget that ObamaCare was rammed through without a single Republican vote in the House or Senate.

It's the unfortunate case that Republicans don't generally support Democratic bills. Witness the recent student loan bill. There is not much question that a better educated populance means a better economy and a stronger nation. It's a truism that we could just pay for college education in a number of fields and reap economic benefits of many times the spending. Indeed, we used to do more of that and the country was stronger when we did.

You meant "you wouldn't approve" rather than "you wouldn't understand".

Positioned correctly, it isn't all that socially reprehensible to state the sentiment that you don't believe you should pay for people who drive their motorcycle without helmets, people who self-administer addictive and destructive drugs, people who engage in unprotected sex with prostitutes or unprotected casual sex with strangers, and people who go climbing without using all of the safety equipment they could.

You don't really even need to get into whether you hold human life sacred, etc., to get that argument across. It's mostly just an economic argument, you believe yourself to be sensible and don't want to pay for people who aren't.

The ironic thing about this is that it translates to "I don't want to pay for the self-inflicted downfall of the people who exercise the libertarian rights I deeply believe they should have."

OK, not a bad position as far as it goes. Now, tell me how we should judge each case, once these people present themselves for medical care, and what we should do if they don't meet the standard.

Citation needed.

I just looked for a minute and found This NIMH study. If you look at the percentages per year they are astonishingly high. 9% of people in any particular year just for mood disorders, and that's just the first on the list. Then they go down the list of other disorders. The implication is that everyone suffers some incident of mental illness in their lives. And given the number of psychiatrists, psychologists, and lay practitioners in practice, it seems like much of the population try to get help at times, if only from their priest or school guidance counselor.

You are not a rock. Can you honestly tell me that you haven't ever suffeed a moment of irrationality?

I'm curious what his stance is on most martial arts practitioners.

I've never heard of one invading a school and karate-chopping a dozen young kids to death. Have you?

Yes, seeing a doctor really is a human right.

Does that mean we should bear the burden of your bad lifestyle choices? Well, we do today. Either those folks are in our emergency rooms, or they are lying on our streets. Either way, we all pay a cost.

It's not clear to me what you propose to do with them. Perhaps you should explain that a bit more clearly.

Hi AC

One would hope that a real scientific study would shed light on the situation. Unfortunately, this isn't it. It's a paper published by a Harvard student club and written by a gun industry lobbyist and a gun enthusiast. No balanced perspective that could lead to a real scientific paper here. The first refutation I found of the paper is certainly not peer reviewed and published in a scientific journal either, but makes a pretty good case that the statistics are cooked. It's here.

Please find a real scientific paper from a researcher without bias and then we can discuss it. This one doesn't quite meet the standard.

I'm sort of surprised at the amount of vitriol toward Eric that comes up unprompted (at least by me) just because I'm interviewed on Slashdot. I'm going to take the high road and not participate in it.

Actually, we would have had a much less expensive plan, but we couldn't get it by the conservatives. It's called single-payer, and I've used it in Canada. It has also been available to me in a dozen other countries that I've worked in, but fortunately I never needed it there. It works pretty well. So well indeed that most civilized countries have it.

I'm sorry that you didn't understand my presentation. Or that you understood it and can't accept it. I've thought about it for a very long time and I'm pretty sure of it.

Thank you. I've only been to Belfast so far, which was great fun, and I hope to spend more time in both Irelands.

I think you have to look at where the funding comes from for Republican and conservative causes. Don't just look at candidate funding, even election advertising has a lot of funding that isn't straight to the candidate.

Although there might be no shortage of self-employed Republicans, they don't really call the shots for the party. It's the very deep pockets who do.

The UK is Great Britain, Ireland, Scotland, Wales, some other pieces, and some of those are partially self-governing (I don't know much about how the Irish Free State works, etc). And then we have the ex-colonies and client states which still consider the Queen their head of state.
