They're already past the "make things worse" stage. That's what austerity brought.

No, austerity didn't bring it. If anything, trying to spend within your limited means will postpone making things worse. Do it long enough and things might even get better.

But borrowing and spending isn't going to make it better, even if they can find someone from whom to borrow.

Leftist borrowing and spending? As opposed to the Right's strategy, which is to borrow much more and give it to your rich business partners?

I don't know how folks like you can live in the real world and parrot these lines over and over again with nothing to show for it. When the left "borrows and spends", the "spending" side all goes to rich business partners. Every single time.

It's a pretty central fact to cooking.

Okay. How does the fact that water boils at 100C help you when you cook? Let me state this another way. Imagine that the inventor of the Celsius scale arbitrarily decided that the boiling point of water would be 1000C. What would you do differently when cooking?

In case you're scratching your head trying to figure out my awesome brain-bender the answer is "nothing".

If water boiled at 385 Kelvin, we'd have made 100C = 385K.

Okay. So? All arbitrary numbers. Like 32 and 212.

Celsius is only arbitrary if you ignore the fact that it's anchored to two immediately useful temperature for most people in most places.

Sigh. Please read my post repeatedly until you get it. I never said that "0" and "100" celsius aren't "useful", just that it's entirely arbitrary. Also note that it won't work in "most places" - it only works at sea level at normal atmospheric pressure for pure water. Anything other than that is slightly off.

Remembers the freezing point and boiling point of water in Kelvin would suck just as much as it does in Fahrenheit. When I've doing physics calculations, I'll use Kelvin, where it's the logical unit leading to the simplest form of equation.

Which again supports my point. For real world use there's little difference between Celsius and Fahrenheit for people who use them. That celsius is based on properties of one chemical compound (out of millions of compounds) really doesn't make it more useful for anything. I mean, if you're at sea level with normal atmospheric pressure and you're boiling a pot of distilled water then you can safely say that it's 100 degrees Celsius. What, exactly, does that gain the normal person? Nothing more than saying it's 212F. Yes, 100 is a pretty and round number but in the real world it is, again, not relevant.

0 is the freezing point and 100 is the boiling point at normal pressure. How is that arbitrary?

LOL. Let me help you:

1. the freezing point (arbitrary but easily observable state)
2. of pure water with no dissolved substances (arbitrary but common chemical compound)
3. at sea level (arbitrary but easily located place)
4. at normal atmospheric pressure
5. on earth (arbitrary but very convenient location)
6. is 0 degrees (arbitrary value which kind of makes sense until you realize that you can still get colder)
7. and the boiling point of water at sea level on earth at normal atmospheric pressure (previous comments still apply)
8. is 100 degrees (arbitrary number chosen for convenience of the units - "10" would be too course grained and "1000" would be too fine grained)

So, yes, the celsius scale is arbitrary, the Fahrenheit only slightly more so. At least the celsius scale can be kind of reproduced in a pinch if you're at sea level and normal pressure and you have water and the ability to freeze and heat it. But, then, if you have all that you can reproduce the Fahrenheit scale, too.

For an idea of a less arbitrary scale look at the Kelvin scale. On it, "0" is the absolute lowest temperature where matter has absolutely no heat content. Of course the scale is the same as celsius so it still ends up being arbitrary in scale, which *any* temperature scale will be. But "0" being "absolute 0" is what sets it apart.

Is their lab at the bottom of death valley or are they using a pressure cooker?
Every time C vs F comes up, the C fans invariably point to C being vastly superior mainly because 100 C is water's boiling point.

"Boiling an egg" really means "heating it in hot water to cause the yolk and albumen to solidify". That can be done at a temperature far below the boiling point of water. This is good because in the summer local news stations can show how hot it is outside because you can "fry an egg on the sidewalk!" complete with a demonstration.

If I remember correctly 120F is the temperature needed. I used to make a custard ice cream which included a dozen uncooked egg yolks that couldn't be congealed. In order to accomplish this safely they had to be heated in a double boiler setup to around 105F and held there for 10 minutes which was supposed to be enough to kill the nasty bacteria that might be in there. It was a bit of a trick because if it got much hotter the yolks would congeal and become unusable.

This is exactly what I came here to say, too. It's easy for someone to sit in their office in DC or wherever and eavesdrop on the entire internet if traffic is unencrypted, so there's an incentive to simply be lazy and collect as much as possible. When they have to physically visit a person's home, office, whatever in order to eavesdrop - this is GOOD. Now there's an incentive to actually *think* and make sure you're doing the right thing before investing the resources needed to eavesdrop.

Good on Disney. Lucas may be ok at imagining a story...

That's part of the problem: "a story". I watched 4, 5, 6, and 1. 1 was bad enough that I haven't bothered to seek out 2 and 3.

I would note that in 4, 6, and 1 the entire plot was "attack the single point of failure on the enemy ship/base for the win".

The looney left thinks that planning ahead is racism. People who plan ahead typically do better in life, but the idea is to claim that anybody who "does better" is in that position due to societal structures that benefit them.

The Seattle Public Schools issued a statement that talked about racism and one of the elements was "future time orientation", another way of saying "planning ahead".

According to the district's official Web site, "having a future time orientation" (academese for having long-term goals) is among the "aspects of society that overtly and covertly attribute value and normality to white people and Whiteness, and devalue, stereotype and label people of color."

The school district took the site down a few days later after widespread criticism, but you can see it here:

Cultural Racism:
Those aspects of society that overtly and covertly attribute value and normality to white people and Whiteness, and devalue, stereotype, and label people of color as “other”, different, less than, or render them invisible. Examples of these norms include defining white skin tones as nude or flesh colored, having a future time orientation, emphasizing individualism as opposed to a more collective ideology, defining one form of English as standard, and identifying only Whites as great writers or composers.

Ironically the anybody who would come up with this stuff, particularly planning ahead and individualism, is acting in a racist manner. It's pathetic.
