  1. Re:What is "real" ? on Higgs Range Narrowed; Hunt Enters Final Stage · · Score: 5, Informative

    As real as the neutrino. The neutrino was a prediction based on a model of physics at the time and remained theoretical for thirty years until an experiment confirmed their existence. Like the Higgs, it was thought to be nearly impossible to experimentally verify for a very long time. And when it was observed, it was not observed directly, but through the behavior of particles it interacted with. The interacting particles, in order to behave as they did, must have interacted with something that had the precise qualities ascribed to the neutrino. Therefore, a neutrino must have interacted with them. Therefore, neutrinos exist.

    Now we have hot and cold running neutrinos and can use them to probe all sorts of interesting things. But we have still not directly observed them in a detector, because, by their nature, they don't show up. But we know that when we see particles behaving as if they interacted with a near massless, half spin object interacting weakly, we call it a neutrino and move on.

    Currently, things weigh more than they should. The mass of a particle is a function of the kinetic energy of the particle and it's component parts, if any. If we run the numbers, we get good masses for some particles, not good masses for others. A proposed solution to this problem is the Higgs field, a nonzero field that permeates space. Anything coupling with this field gains additional mass through interaction with the field.

    Picture a person at a party. Normally, they are free to move through the party fairly easily. Now make that person famous. Admirers flock around, and the celebrity has trouble moving. Nonfamous people are particles that do not couple with the HIggs field. Celebrities are particles that do couple with the field, surrounded by a paparazzi of virtual Higgs particles.

    Nice theory. It fills a gap in the standard model and now the math all works. So now we have to find the particle. You need the mass of a particle to find it in an accelerator. Roughly (very roughly), you need to create collisions where the sum energy of the little explosion is about that of the particle in question, then watch a statistically large number of those to see if something matching your particle appears. If it does, it's off to Stockholm for dinner with the king. If not, it's back to the drawing boards.

    The problem is, the theory doesn't predict the mass of the particle. It doesn't even say if it is one particle, a family of similar particles or a family of different particles. So there's a wide spread of masses to examine. And all the masses are really high, far higher than any other existing accelerator could reach. So we have the new CERN experiment, slowly scanning the possible masses, looking for the particle.

    If we don't find that particle, then we're back to square one, why are some particles heavier than predicted? For decades, we've assumed it was some sort of variant of the Higgs boson. But if that's not the case, it's back to the blackboard for more theories.

    In general, this is a problem for particle physics. Finding or not finding the particle will affect chemistry, biology and general astronomy not at all. It might or might not have an affect on cosmology, but that's hard to say without a particle to talk about. More interesting for cosmology is that while searching for the Higgs, the experiment might come across more esoteric things, such as evidence for supersymmetry. Evidence for supersymmetry would automatically generate the prime number one candidate for dark matter. And nailing down the properties of dark matter would give us another probe of the Big Bang.

    More information than you wanted probably, but I hope it helps.

    Er, they do realize that Kepler's laws do not apply to galaxies. They cannot, in fact, use Kepler's laws because they know quite well that the gravitational contribution of the stuff orbiting the center of mass is significant. That's why they use Newtonian physics in this situation. Our modern understanding of the evolution of spiral arms comes from this sort of analysis. They do not use Special or General relativity in this situation for two reasons. First is that the math is real hairy. Second, at these speeds and distances, it reduces down to good old Newtonian motion anyway.

    As for Dark Matter, yes, there was a flash in the pan article a few years back about someone using General Relativity to analyze rotation curves and coming up with enough extra contribution to invalidate dark matter. The paper was up on ARXIV for about four hours before the first math errors were spotted and brought the whole thing crashing down. And even if that paper held, it wouldn't have explained results like the Bullet Cluster (http://en.wikipedia.org/wiki/Bullet_Cluster), where maps of particulate dark matter have been made. No modified gravity theory or assertions that dark matter goes away under SR or GR can explain those findings. Dark matter is real and we now have tools with which we can spot it. The trick is now to figure out what it is.

    You seem to have a real misunderstanding of how physics, and all science, makes progress. Once we have theoretical models, they are, generally, perfect. A good theoretical model explains ALL available data, or it isn't a good model. Once we have a good model, the only way to improve it is to go actively looking for where it diverges from reality. Only with this new input, divergence from theoretical predictions, can models be refined, improved or even replaced.

    That's why we're hunting the Higgs particle. Fact is, the Standard Model is slightly broken. Without a Higgs mechanism, predicted lepton mass does not conform with experiment. We have a gap right now, a discrepancy. We think we have a solution in the Higgs field. We could, I suppose, assume there's a Higgs field, pick one of the several variants and go with it. Or we could, you know, do some actual science and go looking for the thing and nail down its properties. Along the way, if we see some of the other things we're half expecting, super symmetry, discrepancies in gravity at the millimeter range, broken symmetries, energy leakage at high energies or anything else, so much the better.

    The problem with science is not a lack of fundamentals. The problem is the theories are too damned good. Reality simply does not diverge from the theories unless we get into some really exotic conditions. Why do we need a superconducting particle collider with a diameter measured in kilometers? Because our models are frikkin' perfect for everything up to that. We know they're wrong. We know we can't reconcile GR with the Standard Model. But we won't know how to proceed until we can break either GR or the Standard Model. We don't know what piece of the puzzle is missing until we actually go and look at things.

    It's also a difficulty with language. In physics, mass and weight are two separate concepts. We have comparison words for weight: heavier and lighter. But we do not necessarily have the same comparison words for mass. So we're stuck with the English default construct of more massive and less massive. Sure, we could use lighter in this context and hope everyone understands we really are discussing the concept of mass, not gravitational attractive force to the local big rock, but most physicists dislike that imprecision.

    Message recall. Oh dear.

    Years ago, I wrote the bulk of this feature. It is not an Exchange feature, but an Outlook feature. It works by sending a custom MAPI message that Outlook recognizes and processes. Of course, this only works if all recipients are using Outlook. It also, after we did some usability testing, only deletes unread email, or email that has not been moved to a subfolder (the original version was quite determined and would hunt down and kill the message even if it had been moved to a subfolder, renamed or entered the email protection program). In this way, it did not violate the UI dictum that the computer move things around when you haven't given it instructions to do so.

    So yes, it is Outlook only. If sent to a non-Microsoft mail system, it degrades to a simple notification that the message is being recalled. And it does not a good choice for getting rid of flames you shouldn't have been sending. But within its expected use as a feature - correcting mistakes in email that should have been caught before pressing send, it works fairly well.

    But because it is client based, rather than an Exchange feature, it does cause a new mail message to be sent to each original recipient and, combined with a send-all storm, could greatly exacerbate things.

    Perhaps it is because they are attempting to replace evolution, a well established branch of biology, with ID, a religious argument and very poor proof of God?

    From your post, it appears you are not arguing against evolution, but abiogenesis - the process by which life arose to the point evolution could operate. While we do not have a good scientific theory of what happened, there has been a good deal of progress and the science is far from "it just magically happened". Processes by which amino acid and cell wall precursors arise naturally have been discovered. From there, our understanding is hazy, but there still is nothing that precludes natural explanations.

    Scientists do not accept "it just magically happened" as an argument, as magic falls outside of natural explanations. Nor should scientists be forced to discard promising lines of research into abiogenesis to satisfy the religious needs of a particular subset of some religion. Nor should a group of religiously insecure Biblical literalists be allowed to force there way into the science classroom.

    No, it is not that the acting pre-seventies was universally piss-poor, but the style of acting was different. Dramatical tastes differ for different periods.

    In the thirties and forties, acting styles seem to have been more heavily influenced by stage acting and being able to project emotions and actions broadly enough for those in the back rows to relate. The epics of the fifties seemed to require a larger than life stance to live up to the broad material. In the sixties and seventies, the cultural revolutions playing out in society as a whole seem to have seeped into both scripts and acting. Scripts ceased to focus on epics and refocused on individual struggles and personal drama ("I *am* big. It's the *pictures* that got small." - a perfect lament for the death of epics.). Such scripts required a more natural acting style. The eighties brought us action heroes, with their odd mix of broad and natural styles capped with one liners. The nineties brought us blue screen acting, trying to combine any of the above styles whilst playing to nothing.

    To return to our topic, Battlestar Galactica is trying very hard to stay with the modern, naturalistic style while incorporating a notion of naturalistic production. The idea for the look of the show is a war documentary. The acting style is as natural as possible and the camera movements are, by and large, an attempt to replicate the feel of a handheld or shoulder mounted camera. Effects shots seek to replicate Gulf War footage and acting tries to replicate human emotional response under massive pressure. For some, this succeeds admirably, feeding the show's atmosphere. For others, it just looks like bad camera work to hide the lack of a budget and mopey, neurotic characters portrayed by actors who run the gamut of emotions from A to B, as Miss Parker would say.

So far, it has survived every challenge thrown at it by the fossil record, genetics, comparative biology, chemistry, physics and even computer science. And it has grown more powerful for it. The current incarnation of the theory bears as much resemblance to Darwin's original proposal as modern quantum electrodynamics bears to Ben Franklin's work with electricity.

The theory describing it is, in some ways, better off than the theory of gravity or electromagnetism. We know those two are inconsistent and at least one is due for a revision. There are no such open questions on the theory of evolution.
