Comment Re:Not an YRO (Score 1) 634

Realistically, good teachers are going to be teaching right over the head of the bottom 10 or 20 percent of the class. Otherwise they're not good teachers.

The class cannot stop, or hold back the remainder of the students for a minority who are having trouble. This one of the myriad issues in American education. The whole mantra of "no child left behind" is a farce.

That said, the teacher was in the wrong posting about it publicly.

So, in that sense, I feel like you are both right, and wrong.

Generally, businesses don't invest in LAUNCH VEHICLE and FIRE THINGS INTO SPACE because they have more buttons, figuratively or literally.

Spending a hundred million dollars as a business, without a credible cost-benefit analysis and proof of return on investment is just silly.

I think it's more the nuts and bolts and paint chips, and such things (shuttle insulation panels?) travelling at relative 40,000kmh that can really ruin your day.

As someone else mentioned

"JSC debris scientists said the largest ding returned on a shuttle window thus far occurred on STS-59 in April 1994. The ding measured one-half an inch in diameter and was caused by an orbiting paint chip."

Maybe not wrenches, but other such things are seriously dangerous in space, because they never slow down....

Children from low-income families have only a 1 percent chance of reaching the top 5 percent of the income distribution, versus children of the rich who have about a 22 percent chance.

Anecdotes being what they are....

The US and the UK are relatively unique in this regard in "developed" countries. Those numbers resemble places like Saudi Arabia and African states...

Social mobility in the US and the UK are the lowest in the modern world.

Correlation between father's income and sons is 10% in Norway, 12% in France, 14% in Canada. In India it is 45%, in the US it is almost 60%. It's around 70% in Saudi Arabia and a few other examples of extreme variations, but the US and the UK are pretty much on par with Saudi Arabia in this regard, even if it's much more undercurrent than on the surface.

Sorry to break it to you....

The United States DOES have the *lowest* levels of economic mobility in all of the western world.

It is not a caste system, but it is most closely resembling it amongst "European" countries.

The highest mobility occurs in places like Denmark and Norway, where your parent's education and income has a startlingly low correlation with your future income (where the correlation is almost linear in the US). Places like France and Canada fall somewhere halfway in the middle...

Food for thought.

It is STILL over 1000 times more dangerous to have a backyard swimming pool than an airport that gets hit with a bomb every 20 years.

Perspective, people....

Actually, given the massive money spent to build and promot the AMBER alerts, a substantial number (as in 1000%) more children would have been saved from death by spending that money on things like pool safety enforcement, suicide prevention, automobile safety, industrial chemical disposal regulations, etc.

I saw a study a few years ago, that the number of billions of dollars spent on the AMBER alert system would have been more than 10x as effective in almost 30 different government programs at preventing childhood death and serious harm. Sports accidents, car accidents, cancer, poisoning, pool accidents, natural disasters. These are all substantially more risky to children than abduction, but the 5000 kids who die of drowning in swimming pools each year don't make it on the evening news, so they don't seem to matter.

Of course, actually saving kids wouldn't quite placate the Nancy Grace "ZOMG the poor abducted children" crew quite as effectively. They are about sensationalism, not actually helping society.

Sigh.

The reality is "if it was only one child" argument is a red herring, because it indicates "if we didn't do this, we wouldn't do anything". In reality, it is a bunch of competing interests and we have to choose the optimal one. It's not a choice of "this or nothing" but often proponents of these silly programs pitch it that way to garner public sympathy.

I think AMBER alerts are terrible, a waste of money, and merely a balm for busybodies who want the self-affirmation of "helping children" or "catching perverts" when really, we're just chasing after a bunch of jealous boyfriends and ex-husbands most of the time anyway.

I would suggest that anything that can survive the highly oxidizing environment of an oxygen-saturated solvent at -100C in pitch darkness is probably not going to last long in the ion-saturated solar heated environment of the upper atmosphere, even if it were to escape.

But that is presuming that there is sufficient pressure to force fresh water through miles of solid ice at -100C temperatures without freezing anyway, which there probably isn't.

Even if there is, I would wager that they thought of this and have a "stopper" of sorts in place.

Of course, I would have figured that TransOcean would have put one on their oil rigs too, and we know how that turned out.
