Comment Re:Geo-engineering will be part of the solution (Score 2) 105

"Geoengineering is a bad idea." "Why?"
"Because it hasn't been tested and could have unpredictable consequences."
"So let's do some testing and improve our models of how it works."
"No way, we can't be doing research on geoengineering!" "Why not?"

Comment Re:Common sense here folks (Score 2) 118

Nobody said that the nerves are going to work. Post transplant, the person will certainly be paralyzed from the neck down. That's why this kind of surgery is only appropriate for a paraplegic whose body is about to fail. He or she is not going to stop being a paraplegic, but might get many extra years of life by acquiring a robust new body.

Comment Re:Taller men get more girls the world over (Score 5, Insightful) 298

I doubt that this is right. It's just a misconception to say that in a first-world society, fertility is pretty much the same thing as attractiveness. It's not. In fact, the people who are broadly judged to be most desirable - the people with Ph.D's, sixpack abs and fancy jobs - have fewer children that the average. A much stronger driver of first-world fertility in a place like NL is: Who's sloppy with their birth control, who's impulsive enough to think things like "Yeah, I should just have the baby!", who's someone that thinks that having a child is going to fix the problems in their relationship, etc.

For these fertility increasers to be correlated with height is just weird and hard to explain, but it's obviously real, so there much be some mechanism. But that mechanism is not as simple as "Taller men get more girls".

Comment What's up with the unseparated gas-break pedal? (Score 1) 477

I'll make one prediction right now: No car of the future, clever or dumb, will be accelerated and decelerated with a single pedal oval, the right half of which does the former and the left half does the latter. We might all think that's completely obvious, but look at the interior photo of the prototype. Even Steve Jobs would think it's suicidal.

Comment Re:Need the ISS (Score 1) 152

Do you really think there are going to be humans in LEO turning bolts with hand-held wrenches, and that's how the Mars ship will be built? Did you not notice that even in the safety of Earth's factories, humans aren't really doing that kind of stuff anymore? By the time we get around to building a Mars ship, I doubt our automated manufacturing machines will be worse than now, and unlike humans, these machines can actually be designed to perform optimally in space.

Comment In Finland, teacher spots are hyper-competitive (Score 5, Informative) 213

Check out these facts about Finnish teachers, and weep (if you're American) (source):

Becoming a teacher in Finland is as competitive as getting into an Ivy League school, and Finland offers no other route into the profession. So, there is no Teach for Finland. To teach in Finland requires a five-year master's degree in education. Admission to a teacher preparation program includes a national entrance exam and a personal interview. Only one of every 10 applicants is accepted into a teacher preparation program in Finland; competition to become a primary school teacher is even tougher, with 1,789 applicants for only 120 spots, for example, at the University of Helsinki in 2011-12. Only eight universities offer teacher preparation programs in Finland, which allows the country to ensure consistency from program to program. Contrast that with Minnesota which has about the same population as Finland (5.2 million) but about 30 colleges that offer teacher preparation programs.

I also remember reading that about 90% of Finnish teachers graduated in the top quintile of their class. In the US, that figure is more like 4%. American students of education typically get the worst SAT and GRE scores of all the majors. We cannot ignore these facts when we're comparing educational systems. In the US it's easier to get into med school than it is for a smart Finn to get into teacher school. The quality of the people who make it through means that pretty much every innovation they try is bound to produce satisfactory results, because highly their best and brightest are in charge.

Comment Re:What's the point of the NSA knowing everything? (Score 1) 569

... I doubt that these are the needles they [the NSA] are seeking.

Yeah, but why not? This sort of thing obviously undercuts national security by tying up our cops, making them complicit in some asshole's prank, and causing potentially deadly danger. And compared to the effort and expense of mobilizing and deploying a freaking SWAT team, it is a comparative trifle for the NSA to answer a call from the cops asking for the malicious report to be traced to its source.
