How? The SSN is nowhere on the birth certificate. If your statement was true an identity thief could walk into the county registrar's office and get the SSNs of everyone born in the county.
Also, a passport application requires proof of US citizenship (for which a birth certificate will work) AND proof of identity (which includes a government-issued photo ID). If you have someone else's birth certificate, the info on that won't match the photo on the ID with your picture on it. (I'm assuming here that they do some checking to make sure the ID is real.)
The obstacle here is that the farmers don't control the consumer end of the market like the oil companies do (through their branded gas stations). They have to settle for whatever price the grain elevators and the huge food manufacturers are offering.
The market is somewhat fragmented on the farmer's end -- the price is docked for lower protein in the wheat, high moisture levels, and such. Think any of that makes a difference once they make it into Chocolate Frosted Sugar Bombs? Not a bit. (Well, maybe the moisture does, but certainly not the protein.) Food manufacturers have an interest in not fragmenting the market on the consumers' end, for exactly the reasons you mentioned. And there's not much the farmers can do about it.
At least, that's my understanding. But I'm not an economist.
Much as I hate to nitpick (and at the risk of obscuring your point), Binnie seems to be American from birth. You're thinking of Mike Melvill, who piloted the last couple of flights.
As made famous by the movie (which I can not find presently!) where the teacher inducts the teen kids into a new code of conduct which turns out to be Nazism.
Are you thinking of The [Third] Wave? Students couldn't understand how ordinary citizens could become genocidal Nazis, so their history teacher (Ron Jones) decided to, well, show them. It was a classroom experiment that got out of control, and later the whole thing was turned into a book and then a movie.
My high school US History teacher had us read the story about it. Pretty frightening, interesting stuff.
The Alchemist by Paolo Coelho. It's not directly related to computer science (which is why I didn't post this sooner), but it has changed my life. On the surface, it's a simple story about a boy who has a dream and sets off on a journey, but I've read it close to 10 times now and each time I see the story differently and take different things away from it. The subtitle probably says it best: It's "A fable about following your dreams" -- and without all the sappy-sweet crap that usually comes with books about following your dreams.
Well, blood is different from stem cells, of course. But since you asked...
If a mother's blood is Rh- (ie her blood is A-, B-, AB-, or O-), and she has an Rh+ baby and is exposed to that baby's blood, she will start to produce antibodies to that Rh+ factor. If the woman gets pregnant with another Rh+ baby, her body can launch an immune response to that baby, causing all sorts of problems. Nowadays doctors test for and anticipate the problem, and simply give the mom a shot of anti-D immunoglobin, which prevents her body from producing the harmful antibodies, and everyone comes out just fine. (More details) -- or just Google for "rhesus antibody pregnancy"
Mostly what you'd expect. Lots of things like "Techniques for navigating layers of a user interface" and "Prospective view for web backtrack." A complete list can be found by searching the US Patent Office.
Incidentally, that search function is pretty icky, and could use a little of Dr. Nielsen's help. Ugh.
I always get confused when I hear glassy, but it appears to be related to the material structure, not any transparency/translucency of the material.
Right. "Glassy" is just another word for "amorphous"; that is, noncrystalline. Glassy materials are solids, but they aren't arranged in any sort of pattern. In crystalline materials, the atoms are all lined up nicely in a repeating pattern. In an amorphous, or glassy, material, the atoms are arranged randomly. Window glass is simply amorphous silicon dioxide; crystalline silicon dioxide is quartz (or opal, jasper, or a few other semi-precious stones). Whether a material is crystalline or glassy doesn't have any effect on its transparency (or lack thereof), like you said.
A good way to get your hands on a piece of amorphous metal is to find one of those little white plastic anti-theft thingies they stick in CDs and some books. (Hopefully they haven't changed them in the past few years since I last did this.) Cut it open on one end and pull out the two little pieces of metal inside. One is regular old crystalline metal, and the other is amorphous metal. The amorphous metal can be bent and played with, and won't deform unless you pretty much fold and crease it like a piece of paper. Neat stuff.
A friend from New Zealand recently had to explain it to me. "Gob" is a slang term for mouth. If someone smacks you across the mouth hard enough, you'll be stunned and speechless.
Close. MIT frat boys often go for Wellesley girls. The normal guys often go for MIT girls. And you assume that all the females are odd, while none of the male ones are. There's a pretty wide normalcy-eccentricity spectrum for both sexes.
You're comparing purified, bottled water to spring water. I was asking if bottled water has higher standards than tap water. A quick skim through this page doesn't reveal any stricter standards for bottled vs. tap water. (But, like I said, I skimmed.)
Also, there are numerous types of bottled water -- eg spring water, "drinking water", distilled water, etc. You pointed out that the standards are different for each class. Does that make a difference in purity vs. tap water?
By the way, I wasn't "knock[ing] RO". In fact, I'm not even solidly on one side of the tap water vs. bottled water debate. I'm just a skeptic. And really, I'm not sure why I'm asking all these questions. It's not like we're not off-topic far enough already...
What's guaranteeing that bottled water is any better? I've seen plenty of water bottles for sale that plainly state that they're bottled from some city's municipal supply. Are there regulations on bottled water saying it has to be "cleaner"?
Right. I was trying to explain how polymerization can have a huge effect on properties, using an example that most people would be familiar with. Not many of us have a chance to play with ethylene glycol or PEG, but almost everyone is familiar with polyethylene, and probably also knows the general properties of methane, if not ethane. Guess I should have made that clear. Sorry.
And yes, organic chem 2 rots your brain. Organic chem 3 melts it completely. Polymer synthesis, however, is just plain fun.:)
Since the PEG a fluid, I'm guessing that the vest has to be sealed anyway. Maybe I'm assuming too much, though.
Polyethylene glycol (or any polymer, for that matter) can be made at various molecular weights. Molecular weight will determine its physical properties, including melting/freezing point, as will the amount of silica mixed in. I don't see anything in the article indicating its MW, but hopefully they'd make sure it's workable within a wide temperature range.
The repeat unit of polyethylene glycol looks like this:
-CH2-CH2-O-
So with polyethylene glycol, just attach that unit end-to-end over and over again. How many repeat units you have in the polymer will determine the melting point and many other properties. The MSDS you link to is for PEG-8000, which probably means it has a molecular weight of 8000.
Incidentally, you'll notice that the ethylene glycol unit (the monomer) is different from the PEG repeat unit by an H2O -- water is a byproduct of the polymerization.
Polymerization does make a huge difference in properties. Polyethylene is basically ethane (or, if you look at it another way, methane) attached end-to-end, but polyethylene, of course, is very different chemically from methane.
Finally, I get to post to Slashdot about a technical subject I know something about. Quick, someone, mod me up! It may never happen again!:)
Maybe for you. I find that I need a break in the middle of the day to reset my brain. If I work through lunch my afternoon isn't nearly as productive as it would be with the break. While you seem to have already made up your mind that everyone but you is a lazy, nonproductive freeloader, consider that I regularly worked 50+ hours/week, and often far more.
In every major world religion there's an equivalent to the Golden Rule: Do unto others as you would have them do unto you. (Oops. I just quoted from the Bible. There goes my argument.) That is, every religious leader's message boils down to "Be good to each other." What's so unreasonable and illogical about that?
Yes, unfortunately, there's a tendency for people to turn religious faith into dogma. *That* I object to. But there's a difference between what's originally taught and what people eventually turn it into.
Well, there's Holger Kersten's book Jesus Lived in India, in which he argues that Jesus lived in northern India and studied with Buddhist monks for some time before returning to Palestine to begin teaching. Kersten bases his arguments on Buddhist texts and other evidence. Of course, there's a lot of debate about this (to put it mildly).
Also, there are about five million Ahmadiyya Muslims who believe that after the Resurrection Jesus and Mary traveled back to India, where they eventually died. Jesus' (supposed) tomb is a shrine in Kashmir.
It's not just you. CASPIAN, an anti-card group, has a blurb about a recent survey that showed supermarkets without loyalty cards ranked highest in customer satisfaction. (Full survey results here.) While there are many things that go into customer satisfaction, it does illustrate that you're not the only one who feels that way.

3. They *did* have enough money, but pressured (overtly or not) the woman into giving her own eggs anyway -- which is the whole point of the article.
(Or didn't have the money. The ethics are still the same, I'd argue.)

Why not put the sugar and milk in before the ice? Even coffee shops should be okay with giving you a glass of ice and a cup of coffee.
