  1. Re:composite aging? on 7 Myths About The Challenger Disaster · · Score: 1

    Interesting. I don't know myself, I just heard something about the tiles like I mentioned.

    However, the fact is that NASA still has not historically had any routine procedures in place for inspecting the shuttle for damage, especially since the issue of falling debris at launch was a known issue. The investigation into the Columbia incident clearly established the management faults leading up to that.

    I do not think that it was an incident that was inevitible, nor an act of a spiteful deity. NASA has a clear history, now illuminated by two fatal accidents, if not three, of ignoring its engineers' warnings of dangerous issues in favor of the more risky path of forging bravely (but foolishly) ahead.

    I do not know if they have done enough to purge the culture of those tendencies, but for future astronauts' sake, I hope so!

    Somebody correct me if I'm wrong, but I think I read somewhere that the shuttle tiles are always being replaced - not all at once, but the underside would be inspected, inch by inch after every flight, and tiles showing any signs of wear or damage are replaced.

    I would think that the leading edges of the wings would be areas that would lend themselves to fairly frequent replacements, given the forces those tiles would be subjected to.

    I think one thing that clearly came out of the investigation of the Columbia accident is that the failure of NASA to have ANY kind of inspection routine or any ability to replace damaged tiles in flight was a management failure on the order of what caused Challenger's demise. I think that would pretty clearly take it out of the realm of the acts of spiteful deities...

    "...consensus in the sense of informed scientists who follow logical processes using the current research."

    Ok, yes, that's the ideal. I wish it always were that way. But we all know it isn't. Many prominent scientists (and a lot who aren't) can be pretty egotistical, and can get those egos pretty wrapped up in their own pet theories. Scientific history, again, is rife with such stories, and they can happen today as easily as a hundred years ago, cause people haven't changed that much.

    As the previous post said, such consensus IS harmful, especially when "everybody knows"! That's what both of us are saying!

    If the ideal you speak of was really something that always happened, we wouldn't be having this discussion, now would we?

    Wow! You make the scientific process seem awfully subjective! You even say so.

    Sorry, but the observations are I think most often a lot more objective; it's the interpretation that's subjective.

    So, really, the only thing that can differentiate between an incorrect and a correct observation is a cold hard fact and that's another, substantiating observation. Now a given interpretation of those observations may be very subjective, and probably always are.

    I CAN therefore refute your theory, even if its a majority consensus - by submitting solid, repeatable experimental evidence that it is wrong. And that, my friend, is where your argument falls apart.

    Now we get into the realm of consensus, where things get political, and that is my entire point. Because consensus IS political, and subjective, and is not always based upon cold hard facts, at least not always enough of them, it is not a good idea to base public policy on such a consensus. If a consensus is based upon solid evidence, such as, for instance, the science behind the effort to study Mars, then no problem. Everybody pretty much agrees that what we're doing is reasonable. (Mostly, anyway) But if everybody agreed that the climate/warming issue was a slam dunk, we wouldn't be having this discussion. So until we can come to such a consensus, the government is rightly holding back until the scientific community can come to some agreement.

    "The IPCC WGI reports are not written by politicians."

    Didn't say it was. What I said was that the current state of consensus in the scientific community is political in nature. Being composed of human beings, it has to be. Where you have a hierarchy of indiviuals (in this case ranked by perceived status as published scientists), other scientists who want to be published (thus joining the ranks or raising themselves in those ranks), one must avoid being too contraversial or risk being rejected. (I know that's greatly simplified, but I've heard enough scientists working for my employer complain about it.) It's a matter of either join the consensus or be marginalized. I realize that for the vast majority of issues that's easy. Simple solid scientific evidence, etc. makes it non-controversial. But too many in that community have their egos vested in their pet theories, or stuff they've worked their whole careers on. That's only human, but it contributes to the political nature of the consensus process.

    But don't say that the entire community of scientists agree on this issue - I know they don't. Scientists are like cats - they don't get easily herded. If this issue were a slam dunk, like perhaps saying that the sun is a given distance from the earth, that's one thing. But something that's this complex, forget it, that isn't happening, and not because some people have a vested interest in oil! That's just too simple an excuse!

    And as for policy, you're right, and that's the way it should be in a free society, expecially for as controversial an issue as this is. That's not a bad thing, it's good. People supporting your apparant side probably don't agree it's good, cause it keeps you from doing what you think is the right thing. But that's better than everybody being dictated to...

    Please! Read the post. Nobody said SCIENCE didn't work. My comments, if you had read down to the end of my post, were meant to note that using poorly backed (with real, solid, non-controversial evidence) consensus is a bad way to either do science or set public policy.

    No, all consensus' do NOT always come as the result of good evidence; that's the point. Scientific history is rife with examples of theories or hypothyses that were accepted by consensus that turned out to be incorrect, and had been based upon slim evidence. Granted, as you note, such prominent failures are fewer as science gets more mature, but since the consensus process is based upon pure politics within that community, it still is capable of happening.

    "A failing of science, not consensus."

    Precisely. Just because there was a consensus didn't make it right, and people doctors worked on based upon that consensus often died because of it! It took people willing to buck the consensus to discover evidence that the consensus was wrong.

    "When push comes to shove, the only thing that differentiates between correct and incorrect observations is majority rules perception."

    Precisely my point! When a majority so affects what people see scientifically, that really does make for BAD policy (as well as bad science)!

    I'm not proposing anything. What I'm saying is that holding up a consensus only means that most people in the argument think a certain way, but that doesn't make it so. Therefore, don't make public policy based upon that consensus unless the evidence to support it is pretty convincing! That's all.

    Yeah, consensus! It's gotta be the best!

    Look two hundred years ago, the consensus among what passed for doctors was that bleeding was good for all kinds of things, and that washing one's hands was for the squeemish. Now we know better.

    The point here is that, until we have more evidence, and more is known about weather and climactic systems on this planet, we really won't know for sure whether we are the proximate cause of this apparant warming trend. Are we contributing to it? Probably, but we don't KNOW. Climactic science isn't really an empirically provable thing; we don't have the ability to experiment with hypotheses to see whether they hold up. The only experimental lab we have with all the data points is our own planet!

    And, no, we don't have to go with what most people perceive. We have to go with what science objectively can observe, over time.

    A consensus can change - they do all the time in the scientific world, as new facts are learned. And as history has proved, a consensus is not necessarily a good thing to base policy on.

    Don't you mean INDIRECT costs? A building or toilet paper aren't direct costs - the expense of the assembly line, or a payment to a third party manufacturer is. INdirect costs are called overhead, cause those costs are shared among ALL your products.

    I don't think my definitiona are that different, in fact they're pretty much what accounting standards call for, and how companies cost their products. You were talking about a cost analysis based upon manufacturing costs only, I repeated over and over that I was objecting to the article (not the analysis) failing to mention overhead, and you kept misinterpreting the terms I was using.

    You're right, in a manufacturing analysis, the overhead isn't important. But the article /. linked to wasn't just talking manufacturing analysis, it was talking about Apple's cost vs how much they were making on each computer. That obviously needs to include the overhead. That is a standard practice when you talk about profit. The terms I used are standard accounting terms, and I was using them in ways that match standard usage.

    I really don't think that "their building" was a terrible example. It is exactly the kind of expense I was talking about! I believe that most real estate amortizations take place over 30 years, so they still might be writing that off, plus, I'd assume they've made changes, renovations, etc., over the years. With a large campus, the expenses never stop. They DO have more than one building there, don't they?

    Of course, Apple does a lot of marketing - and, guess what? THAT'S an indirect overhead expense, too! All part of what I was saying...

    Sorry, but we disagree again. The overhead is NEVER low enough its silly to bring it up. They have, I think someone mentioned on another forum here, tens of thousands of employees? I would doubt that their CFO would call such costs trivial! ALL of those salary costs are recoverable expenses when they set product costs. So is everything else they do that's not production: toilet paper, copy paper, utilties, the list is endless.

    And my point was that the entire article, while being about a production analysis, when they started talking about what Apple was making on each item, should have mentioned the overheads other than production that affects that profit.

    And in case you didn't notice, they DID mention that Apple may be getting an even better discount than they had figured - these guys aren't stupid.

    You sound as if you don't like these analysts work - well, that was part of my point, in case you didn't read! I also think their analysis of Apple's cost is wrong, in the main, as I said, due to the failure of their analysis to include overhead.

    And again, it's not just manufacturing costs that are included in the cost of a product. ALL of a company's expenses in producing a product, from conception, design as well as common expenses such as "physical plant" (a term used to describe ALL of a company's buildings, even offices), and the cost of salaries, even of enployees not directly involved in the manufacturing of the product. Otherwide, they get no return on that expense.
