    I see you missed the subtleties of my meaning.

    First lets deal with the ridiculous. An institution whose authorities have never experienced marriage and procreation presents itself as an authority on marriage and procreation.

    Second and more relevant is the churches position on the status of a fertilized embryo. The church declares it to be human. I do not agree. I have that right. Therefore, the Pope's pronouncements on my personal reproductive choices are as arbitrary and ridiculous as if he had told me not to get a flu shot.

    Do you see now?

    You sir are an apologist. It is not easy to adopt, there are simply not enough babies to go around. Third world adoption is not easy, and there are moral questions revolving around what practices it encourages in the countries the babies come from. Like, for example, the culling of female babies.

    The root problem here is that this religion has made you feel empowered to pronounce upon and, had you the power, dictate the personal actions of others. Religion does that. If there is one thing the followers of most major religions can not do, it's mind their own business.

    Thank you for your recent guidance on my medical issues, in particular my infertility. I have been wondering how to proceed. Now I understand it is God's will for me not to have children.

    I will be sure to convey your disapproval to my sister that she allowed doctors to perform a Cesarean Section on her during a difficult childbirth. This was, after all, nothing more than medical intervention to allow procreation and must therefore be against God's will, correct?

    I look forward to your continued leadership on these issues. In particular I will find inspiration in the way you will accept God's will by not seeking medical solutions to your future health issues.

    FADEC = Full Authority Digital Engine Control. On the Rolls Royce Trent 800 engine its called an Electronic Engine Control System (EECS).

    The article describes the EPR (Engine Pressure Ratio, a measure of the power output) as slowly decreasing in both engines at the same time. If thats true it doesn't sound like fuel starvation. One: the EPR would simply drop to zero, not tail off, and two: the engines are unlikely to both stop at the same time.

    There was a 767 that ran out of fuel over the Atlantic some time ago, their salvation was that one engine ran for several minutes after the first one quit. In that case they were feeding off different tanks. I'm not a systems guy but I believe that's the normal way of doing things, because what's the point of having independent engine systems if the fuel source itself for the two engines isn't independent.

    The 777 was the first twin to get ETOPS (Extended Twin Operations (or as some call it Engines Turn Or Passengers Swim)) to allow it to operate in situations where it might have to fly for two hours on one engine to get to the nearest airport. To get that certification the engine systems have been scrutinized by the FAA who are, shall we say, detail-oriented people.

    Something as obvious as taking the fuel for both engines from the same tank is unlikely to be procedure on that plane.

    Having said all that, maybe on landing the fuel system is configured differently than for cruise.

    I just don't think it feels like a software thing. They tend to be catastrophic and weird and scary. I like the fuel contamination theory. It was coming from China right? Who knows what gets into fuel in China.

    There is a big difference between downloading some piece of crap song because it's there and it's free, and going out and buying a CD or paying iTunes. Even at .99 per song, you have to at least want it a little bit.

    Let's say one out of ten people did not buy the song because they downloaded it. My intuition tells me thats reasonable. That would mean over 90,000 downloads were assumed.

  12. Not "New Type"... on New Type of Fatigue Discovered in Silicon · · Score: 4, Informative

    It's old fashioned fatigue, and it isn't new. This paper quotes (2nd para) 1992 work that demonstrated fatigue in micron-sized silicon specimens.

    Silicon is a typical low ductility material that does not tolerate cracks very well because there is very little plastic deformation at the crack tip (the process zone). Fracture mechanics is based on an energy balance, when the amount of energy absorbed by the creation of the fracture surfaces (the surface energy) plus the amount of energy required to do that plastic work in the pz is equal to the amount of strain energy in the structure that's released when the crack gets bigger (the strain energy release rate), the crack becomes unstable and the part goes bang.

    The strain energy release rate varies with the load and crack size, for a given crack size at loads lower than the critical load, pre-existing cracks (there are always cracks even if they are microscopic) open a bit and the pz deforms. When the load is released, the pz doesn't go back to it's original configuration. Repeating the apply-load remove-load cycle progressively grows the pz which causes the crack to get bigger in some complicated ways. But think of it this way, the crack tip is theoretically infinitely sharp (the limit is the inter-atomic distance of the material). This discontinuity causes infinite theoretical stress which causes the atomic bonds to break at the tip. Process zones have been the subject of countless PhD theses.

    In a low ductility material the energy absorbed by the pz is small compared to the energy absorbed by the surfaces created when the crack grows. Remember the pz is responsible for fatigue growth, the pz plus the surface energy is responsible for unstable crack propagation. So a small pz means you have to load the material close to the crack instability load to get fatigue growth. With a small enough pz it's impossible to load the material accurately enough to grow the crack without breaking the part. So THATS what they mean by silicon being immune to fatigue.

    It seems like the reason this is not the case in microscopic silicon specimens is another PhD topic, the explanation is complicated. Oxidation caused by humidity in the air is a factor, as well as loading in the compression mode.

    Again, all this has been known for many years.

  15. The Zeno Effect on The Universe Damaged By Observation? · · Score: 1

    TFA refers to the Zeno effect, which I hadn't heard of before. This turns out to be an effect whereby the decay of a particle can be suppressed by continuous observation of the particle.

    The thrust of the argument is that dark energy could spontaneously decay, resulting in a new big bang. The probability of decay decreases with time, and by observing dark energy the decay probability is reset back to its value at time zero due to the Zeno effect.

    Being a very very amateur reader of quantum mechanics, all I can say to this is, OK if they say so. One thing I did run across is that wikipedia's entry for the Zeno effect claims it only applies to microscopic particles, not macro systems.

    My question would be, wouldn't dark energy as a whole be considered a macro system? Surely an individual quantum of dark energy is not what humans observed. I would have no idea to whom I should address that question.

    Relatedly, I find this paper to be very helpful.

    Type "define:revolve" in Google and you will find the definition of "revolve" encompasses the concept of "orbit". In fact, the word orbit is used in several definitions of the word revolve. If I had used the word "rotate" you might have had a point.

    If once accepts Mr. Einstein's assertion that no frame of reference is to be preferred over another, then I may indeed chose to observe the Earth-Moon system from a point on the moon and say "the earth is revolving around me" and this is a perfectly legitimate point of view.

    However, the equations of motion are more complicated if once choses a non-inertial frame of reference in this way. Which is why Johannes Kepler, being the towering intellect he was, chose to put his reference frame at the center of mass of the system, because mathematicians strive to reduce their results to the simplest, most reduced form. This in no way means such a coordinate frame is physically "right" while all others are "wrong".

Canada spends less on health care than the US does, although the reasons for that are hard to summarize and are not simply the oft-mentioned reduced overhead that results from eliminating the insurance companies (ref). Whatever the exact explanation, if magically the US woke up tomorrow with Canada-style health care, overall costs would go down. No extra money from the war budget or anywhere else would be needed.

    Of course, Canada has it's share of bureaucratic nightmare government programs, but health care seems, for some reason, to be reasonably well run as such things go.
