people who think science is the right tool for every problem domain are not as smart as they think they are.
Very true. Science only has an advantage when reality is involved.

The first telescopes used a pair of lenses, then mirrors, then finely-created mirrors, then a high quantity of parabolic radio dishes, then really really really big mirrors - launched into orbit. Two lenses were (roughly) affordable by the common man. Mirrors, also affordable by the common man who had a tax return. Then a wealthy hobbyist or dedicated scientist, then a research lab, then a country.
The difference between "how much it costs for the stuff to find new stuff" and "how much new stuff that really expensive stuff will be found" are the questions at hand. We live in an infinite universe, so there's an infinite number of discoveries to be made. It just starts to cost impractical amounts of money after a while.
Her'es a picture of the telescope used for the Sloan Digital Sky Survey, which has mapped a substantial fraction of the observable universe:

A two-meter instrument. Much of the innovation in modern cosmology is coming from data processing, not just building bigger and bigger mirrors. People are actually pretty clever, and can work around boundaries in surprising ways.
Actually, it doesn't omit that at all, it states their prototype is 2000mAh.
I stand corrected. Thank you!
Some of the people opposing this include very educated folks like engineers. So don't think that the only people who oppose Common Core are people who are uneducated.
Pretty much the very last people on the planet who should be deciding how young children are taught math are people with engineering degrees. Engineers are taught an especially mindless point of view on what math is and how it is important, and walk away with an entirely undeserved sense of superiority about their insight. This is precisely what I mean about people "who don't even understand that they don't understand." It often actually gets worse with higher levels of education, ironically enough.
EngageNY is idiotic with math. There's no more working with numbers. If you have 1.62 divided by 0.27, you don't actually do the math. Instead, you draw 162 little boxes. Then you circle them in groups of 27. Then you count how many circled groups there are to get your answer.
The more I see parents bringing up stuff like this as to how "stupid" the Common Core math curriculum is, the more I realize that the fundamental problem is that the parents aren't educated well enough to understand why this is a good way to teach math. Which is a great argument for a new way of doing things: the old way of doing things apparently utterly failed with these parents, who don't even understand that they don't understand.
There's also the group that see idiocy all around and, knowing they can't fight it all, fight some battles and toss their arms up on others.
For example, my wife and I are fighting against EngageNY, Common Core, and the high-stakes testing that New York State has implemented.
Sure, that makes sense. Fight scientific illiteracy by opposing any attempt whatsoever to improve education. Way to go.
While Hydrogen is significantly more dangerous, depending on the overall cost and possible ways to limit the dangers, it may be an option.
I for one welcome the gargantuan exploding lawnmowers to our skies.
Duh, the centrifugal force is an effect, not a force in itself. That's what we were taught in physics at least.

I DO NOT send my daughter to a govt school that teaches her to grow up to be a lgbt whore without rights. SHE is going to a German school and at home she is learning to despise the government.
Parent is the poster-child for compulsory public education. Some kids need to be rescued from their parents.
