    This isn't electoral interference. It is an attempt to prevent censorship and aid people who are being oppressed and persecuted.

    Whoa whoa whoa, don't let your (justified) sympathies with the opposition allow you to bastardize the language. Pressuring a company to do something that would help overthrow a regime during an election *is* electoral interference. The fact that it also a) prevents censorship, and b) makes us feel warm and fuzzy, is irrelevant.

    Franky, I'm quite troubled by this. I haven't consulted the appropriate materials, but I'm pretty sure there are at least some international norms against interfering in an election by "giving aid and comfort" to a ruling regime's internal enemies.

    Imagine if the Chinese maker of a common cell phone exploited a known backdoor to make all such phones blurt out "vote for Obama" on America's election day. Would that could as electoral interference? Remember, they could just as easily claim they're "promoting free speech" amongst "people who are oppressed".

    *is the OP*

    I must confess, you have me stumped. I had forgotten about the supersonic thin-plate orifice flow, and to be honest, I don't know how far the information theoretic analysis I gave of gas leaving a tank carries over to that. (And FWIW, it looks like node turned my point into a circular argument.) It's also been a while since i took gas dynamics, and remember very little of the vena contracta problems.

    In the article on orifice plate, though, it looks like a fundamentally different situation, that of pipe flow. My point referred to flow out of a tank, and the reason I gave for it choking at the speed of sound was basically a sort of "you can't get there from here" argument. That is, *initially* supersonic flow could stay supersonic through the hole, because it's already supersonic. But if it starts out *stagnant* in a tank, it can't *accelerate* to supersonic flow because:

    1) The inside gas must "know" the pressure ratio is supercritical.
    2) This "knowledge", in the form of a compression wave, cannot travel faster than the maximum compression wave speed, which maximizes its net velocity at zero and chokes the flow of information back into the tank.

    However, if I'm wrong, and the vena contracta setup applies to tanks as well, or accelerates flow in pipes where the flow starts out subsonic, then the explanation I would give, as to why that shape permits information to flow back across the subsonic/supersonic gap, would be:

    "The outlet speed refers to the cross-section-area-averaged speed; not every particle in the cross section must be supersonic, or even going to the right in the diagram. The vena contracta shape forces the gas flow to the center of the hole, where it exceeds the speed of sound. It can 'learn' of the lower downstream pressure because the gas flow at the outer edge of the hole is *not* supersonic, and so information can propagate back upstream along that outer edge. However, it requires a special orifice shape to get the cross-sectional speed variation to do this; otherwise, like if you just stab a random hole in a tank, the speed will be very nearly uniform across the cross section."

    But I'll admit, "you got me". :-/

I call back to report on how it's working -- as I was told to -- and spoke to a nurse. Then I get a call back to stop taking D and take E instead.

    Then I do my part to clarify: "So, I should be on A, B, C, and E then?" "Yes." THEN I go to the pharmacist to pick up E, who tells me, "Just don't take any B with this." WTF?

    So I call back and explain what happened -- to a nurse, of course, doctor can't be bothered to be involved at any point in patient care. Later, I get a call back saying "Oh, um, yeah, you're not supposed to be on B."

  14. Re:Sort of Hawking Radiation on First Acoustic Black Hole Created · · Score: 4, Interesting

    That's somewhere in between a metaphor for Hawking Radiation and the real thing.

    Not a physicist, but here's how I think the metaphor between the experiment and the real thing is supposed to work:

    Speed of light: maximum speed information can travel through a vacuum ("the void")
    Speed of sound: maximum speed information can travel through a medium composed of atoms ("substance")

    (When aircraft go supersonic, the air they run into is incapable of "preparing" to be hit, in a manner of speaking...)

    We can't create stuff that goes faster than the speed of light, but we can create stuff that goes faster than the speed of sound. And just as you can't go fast enough to come back through an event horizon, information can't propagate fast enough in the experiment to go back across the subsonic/supersonic boundary. This shows us what it looks like to be in a situation like that of a black hole.

    By the way, there's a similar, cheaper experiment you can do: pop a hole in a pressurized container. The gas cannot escape it (at the outlet) faster than the local speed of sound, which is obtained whenever the ratio of pressure inside to pressure outside exceeds a critical value. One gas dynamics professor said I can think of it like this: "even though a higher pressure ratio creates a greater pressure potential difference, the gas inside the tank cannot 'learn' of the greater difference because that would require information to go *into* the tank, *against* the gas that is escaping at the speed of sound"

    Kind of like in the setup described in the article...

I was unable to convey to him that I didn't know how to start a conversation with people completely at random.

    I'm not one to buy into the attempt to turn every inconvencience into another officially-recognized psychiatric disorder with a $100 co-pay solution. However, the description did resonate me, and I can definitely see the difference between "normal travails of life" and what they're describing.

    Let me tell you a bit of my experience:

    In college, I joined a large organization. Soon after, I was kicked out.

    So far, no big deal.

    But when I was kicked out, I was told that "numerous people" felt "physically threatened" by me, and I had *no idea* why that was. Previously, some people that were nice to me had suddenly turned around and refused to talk to me. Nobody would give me any explanation except extremely kafkaesque ones.

    Then, through a coincidental connection I had (cousin's friend had also joined the same time I did) I found that people believed I -- a virgin at the time -- had threatened to rape some of the women there. Soon after, I learned of similar, viscious rumors going on about me.

    I filed a formal complaint about this where I explained everything. Then, again by coincidence, I the writeup and the complaint had been destroyed and no one told me they did so. I appealed to another group, who refused to do anything after meeting with me, on the grounds that I "seem so angry" (ya think?). I appealed to the faculty sponsor of the organizations, and got a letter back saying, in a formal tone, "you deserved what you got, bro".

    Getting kicked out of an organization is bearable, of course, but without being given any reason why, all while being stabbed in the back and having what reputation I had destroyed? I couldn't stop thinking about it for years and years. I did try to "get over it"; I sought conseling (and was diagnosed with depression and anxiety) and tried to join other groups, but inevitably was unable to form any kind of relationship with anyone.

    I've explained my situation on slashdot before (can't find the link right now), and people refused to believe me, insisting that I must have somehow done something wrong. And throughout the whole time, I've noticed that my socialization is fundamentally different from everyone else. People suggest that I do things (in social situations) and then I refuse, saying, "but won't they [do something evil in response]" and people are astounded that I would even imagine something like that.

    I also always feel like I'm in some sort of paralysis in my life, where I don't want to make any changes (like join a group, look for work somewhere else) because every concern feels like it's preventing me from addressing the others. "Angry and helpless" described me perfectly. (I use the past tense because I recently got more intensive help and started going to church, where I have more social support.)

    Would I meet the criteria if I went in to be evaluated? I don't know. But if this diagnosis enables psychiatrists to carry over the same tools from treating PTSD, then it looks legit. It certainly runs the risk of being overdiagnosed, and it would be a shame if it ended up like ADHD, but the idea itself doesn't sound outlandish.
