It is actually not that long that man bulieved that the Earth was flat and you would just drop if you sail too far off the coast
Well, OK, if you consider 2500 years "not that long". The diameter of the Earth was measured, to a precision of around 10%, by a chap named Eratosthenes circa 500 BC.
Of course, if you went to high school in, say, Texas, you might believe that Columbus had something to do with it.
I didn't see any putdowns of amateurs in TFA, and you'll not find a lot in the astronomy community. It's one of the few sciences where proficient amateurs can make real contributions...they produce intensity logs of variable stars, and discover a lot of the comets, among other things. And they work for nothing.
My best guess is that the freezing stretches the plastic a bit, especially the parts designed for structure such as the creases. Now the bottle has a higher volume and when the ice melts the plastic doesn't go back to its original shape but rather simply collapses.
No, what's happening is that the light plastic screw-on cap is a bit less rigid than the bottle neck. Freezing raises the air pressure at the top, and a little bit of air manages to squeeze out of the interface. When the ice thaws, the pressure differential becomes negative, and the cap is pressed firmly onto the neck, preventing air getting back in.
I tested this by putting a hose clamp around a cap, and the effect went away.
I keep a dozen bottles of water in my car, and don't bother to remove them in the fall. I get frozen ones all winter, and they never crack. What does happen is that I find them partially collapsed in the spring, and use that as a puzzle for my engineering students.
Of course -- but the head of a government organization isn't interested in how much gets cut. He's interested in how much gets cut from his organization. His solution will be "cut it from those guys down the hall."

Including a few on /.
It's the kind of gag item they sell in truck stops next to the naked women mudflaps. Take a deep breath, dude.
Bad people have cells.
Good people have teams.
Useless people have focus groups.
Self-serving parasites have Six Sigma groups.
Your bang key is stuck.
Yeah, until they invented slavery.
If you're still tipping 10%, I hope you like spitburgers.
There are certainly people who read Leviticus for nutritional advice...
First they came for "hacker", and I said nothing...
Translation: Oops, we're sorry. We only did that because we didn't know you'd tell everybody.
Let's give the History Channel a break. They had to go somewhere after they'd worn out Hitler.

Much like archaeology in the 19th Century.
...if you're the world's biggest douche.
...How much is that in Volkswagens per story?
I don't know what the jetpack does in the event of an engine failure.
It does 32.174 feet per second squared.

$30, and I'll name a star after you too.

It's called the Washington Monument ploy.
Bearing in mind that "shark infested water" is pretty much any seawater not cold enough to cause severe hypothermia...
OK, we'll put you in charge of persuading other people to get on the spaceship so it'll be nicer here for you.
Claire Chennault, OTOH, did indeed run one:

We came up with the modern national park (Yosemite was the first)
Yellowstone.
Mod up, please.
