how to become invisible

Some scientists think that cloaking devices that provide invisibility are technically possible:

Forget Harry Potter and his "invisibility cloak" -- theoretical physicists in the UK and US have proposed a clever way of making objects invisible. It would involve surrounding the object by a "metamaterial" -- a type of composite material that has unusual electromagnetic properties. According to the researchers, light rays incident on the material would be bent around the object, only to emerge on the other side in exactly the same direction as they began. Although the work is only theoretical, the researchers reckon that materials invisible to radio waves could be produced within five years.

It seems like an awfully complex solution to the problem. Wouldn't it be much easier to find a volcano, some gold and a blacksmith with some seriously wicked magical skills?

the internet, campaign finance regulation and the first amendment

If Thomas Paine were publishing today, would he be publishing Common Sense and The Crisis as pamphlets or as blogs? If he was publishing on the internet as a blogger, would he run into trouble with the Federal Election Commission?

This post says that the FEC may eventually place restrictions on "political web sites", including blogs. To me, this kind of regulation is clearly unconstitutional--isn't political blogging precisely the kind of public political speech that the first amendment is supposed to protect? Is there any precedent that would support the FEC if it goes forward with applying campaign finance regulations to bloggers?

love according to nerds

My favorite econ blogger on love:

The thesis is simple, and almost everyone disagrees with it upon first hearing. The symmetry thesis: A given person likes (loves) you as much as you like (love) him or her...Perhaps we like other people for their intrinsic qualities less than we pretend. Mostly we like people for liking (loving) us.

Interesting idea. If this thesis is true, then romantic relationships should tend to be self-reinforcing, growing stronger over time. Does the prevalence of divorce disprove the thesis? Or does the prevalence of divorce suggest that real love is often not at the foundation of modern marriages?

illegal immigration--the real solution

Richard Posner points out the real solution to illegal immigration problems:

Once something is identified as a problem, Americans, not being fatalists, insist that there be a solution. But there is only one worthwhile solution to this particular problem, and it is one over which Americans have little control. The solution is for Mexico and the other poor countries from which illegal immigrants come to become rich. As soon as per capita income in a country reaches about a third of the American level, immigration from that country dries up. Emigration is very costly emotionally as well as financially, given language and other barriers to a smooth transition to a new country, and so is frequent only when there are enormous wealth disparities between one's homeland and a rich country like the United States. The more one worries about illegal immigrants, the more one should favor policies designed to bring about greater global income equality.

I find it ironic that so many people are both vehemently opposed to free trade agreements like NAFTA as well as being determined to eliminate illegal immigration. One of the best mechanisms we have for lifting up the Mexican economy is to integrate that economy more tightly with our own. Granted, free trade is no panacea, but it at least opens up opportunities for Mexico to grow her economy.

Or, let's just annex Mexico.

The Da Vinci Code: an alternate ending (UPDATED)

Robert Langdon: "So, you're the last living decendent of Christ?"

Sophie Neveu: "Yeah, I guess so... What should I do now?"

Robert Langdon: "Well, it seems to me that the most important thing is to make sure that the bloodline continues."

Sophie Neveu:

Robert Langdon: "You know, biological clocks, and so forth."

Sophie Neveu:

Robert Langdon: "Speaking of which, I'd be more than happy to take one for the team, as it were."

Update:

Sophie Neveu: "So, I can't walk on water, but I can call down fire from heaven. The sequel ought to be very interesting..."

know your enemy

Baseball Crank takes a look at how Al Qaeda views the war in Iraq:

in assessing both our progress in this war and how close we are to accomplishing our objectives, we need to step back sometimes and see how things look from the other side. As it happens, CENTCOM released today English translations of documents captured from Zarqawi's Al Qaeda-in-Iraq ("AQIZ") that were captured in an April 16 raid. Coming on the heels of Gen. Barry McCaffery's assessment (see here and here) of the war from the US perspective, it's interesting to see almost a complete mirror image of the strengths and weaknesses of the other side and the lessons we can draw therefrom in determining how to sufficiently demoralize the enemy to bring about a decision by the other side to throw in the towel and move its resources elsewhere

The captured documents reveal that Al Qaeda has essentially given up on military victory, instead foccusing on

a media oriented policy without a clear comprehensive plan to capture an area or an enemy center. Other word, the significance of the strategy of their work is to show in the media that the American and the government do not control the situation and there is resistance against them.

His conclusion:

This is such an obvious point that it's amazing it needs to be repeated: the United States can only be defeated by bad press.

Fortunately for Al Qaeda, our press is pretty bad. I'm sure if political pressure leads to a premature withdrawal from Iraq and a bloody fracturing of the nascent Iraqi government, members of our press corps will sleep easy at night in the knowledge that their negativity had nothing to do with the unpleasant consequences.
