    BP has made a lot of noise about how they've paid more than that already, $300 mil+ I remember reading.

    But speaking of closing the barn door, if that sounds like it's just PR, well the PR loss of having this spill go on right as they're talking about expanding off-shore drilling is costing them a lot more money than they're worried about spending on cleanup.

    Um, no it isn't forgotten. It's very good they're doing that for the most likely case that nothing else will work, which makes sense given what an enormous task it is doing anything that deep.

    But you're damn right I'd go ape-shit if they did nothing else, because it's unacceptable for them to not do everything possible to try to stop it earlier.

    You're also right, they're laughing all the way to the bank either way.

    There are serious risks for BP here, and serious costs too.

    Politically, there are big risks. It's one thing to dump a bunch of oil and ruin the lives of a bunch of fishermen on a coast in Alaska with a drunken captain for a scapegoat. There are major population centers along the gulf that are going to notice and care if their coast gets slimed. If they can't stop this soon while the damage is minimal, and the ultimate culprit isn't even human error but the difficulty caused by the insane pressures deep in the ocean? Yeah there goes their drilling plans, future profits from future rigs *poof*, up in smoke.

    And forget the cleanup, they are losing serious money right now! You think BP doesn't really want to reclaim 85% of the spilling oil by putting a dome over the spill asap? Then they can spend the next few months making money off this well before the relief well is done and they seal it off. Make more money and secure their future by reassuring people that the risk of future drilling is minimal?

    Yeah, I have every reason to believe that BP is doing everything they can to stop the leak asap. They have every incentive to do so, and I doubt any of it is just a show. It's still true that it's not extremely likely there's anything they can do. We're all resigned to that, though we all have motivation to try.

    But don't worry, I realize BP will still end up making money, and that they don't fundamentally give a shit about oil spills other than as factors in a spreadsheet.

    The California seafloor leaks are much larger. I don't think they know exactly how much, but this source quotes "8-80 Exxon Valdez spills", I would guess they mean annually. That's somewhere between 86.4 and 864 million gallons.

    They're talking about the total volume of oil residue contained in the down-stream sediments in the seabed, deposited over an unknown period of time. And it seems like they're talking equivalent pre-biodegraded volume, but I'm not sure.

    The statement about the rate of seepage was slightly further down:

    There is an oil spill everyday at Coal Oil Point (COP), the natural seeps off Santa Barbara, where 20-25 tons of oil have leaked from the seafloor each day for the last several hundred thousand years.

    25 tons/day * 7.3 bbl/ton * 42 gal/bbl = 7665 gallons/day.

    One of the coolest things about the mission itself that I read about is the 'drag free' aspect. To ensure that the test masses are in free-fall around the sun without interference by things like the pesky solar wind, they're housed free-floating in a chamber inside the LISA spacecrafts themselves. The spacecraft absorbs the solar wind or other outside forces while measuring any change in relative position to the test mass and using micro-thrusters to keep itself centered on the mass and thus in the same free-fall drag-less orbit. Effin cool imo, even if I don't think it's first time it's been done. :)

    Studies seem to always show that a population always had those traits. To put it another way: We've never had an experiment that produced a new trait previously impossible to express with the existing genetic encoding.

    That's simply wrong. We've observed mutations creating new features in the lab. "Seems" is an insufficient weasel word for a lack of looking.

    I'll give you that. But the counter-point is that the bible, God's Word, makes claims and implications about speciation. So creationists are not about to say "oh, it looks like we observe something contrary to what God says" and just take that at face value.

    No it doesn't. Nothing in the Bible can possibly be construed as something as specific as a limit on the mutability of DNA and a declaration that mutations cannot happen ergo new traits cannot arise. That's just a ludicrous amount to read into the word "kinds". The Bible and evolutionary science don't contradict each other at all.

    But yes I'm aware you aren't going to believe any science that you think does contradict, that's very clear. Mutations don't exist, or are necessarily bad, whatever it takes, got it.

    Well, talking about it like it was a "pre-enumerated list" is really a disservice to God and an underestimation of what the genetic code is capable of.

    It's your description, and a really big static list is still a big static list, inherently simpler than the same incredibly expressive source of information but with the capability to change over time. Which it demonstrably does. Not my fault you don't like me pointing out this is putting an arbitrary limit God.

    I am fulfilled scientifically and delighted by what God has done. Every time I learn about the increasing complexity and sophistication yet elegance of this universe I'm more amazed by Him. I'm more amazed by an ancient earth, where whole classes of animals with unique traits arose, then vanished never to be seen again, and things the earth has never seen before arose after them. I'm not going to disbelieve the evidence of the world He created because it doesn't match what I think a 500-word summary of the creation of the universe was trying to say. I believe God wanted me to read those words and see His hands in forming of the universe, not read it like a biology textbook.

    It actually gives more credit to God's than any other ideas we might have had about it.

    I think it gives Him more credit to accept the existence of both natural selection to choose among traits, and with a mechanism for new traits to arise. It takes both to achieve the tremendous and changing diversity of the world's life, where life that exists now has features completely new and never seen in previous life.

    It's an interesting new line for Creationists to draw in the sand, where trait selection is okay and species changing over time is okay, but God must have had a fixed set of possible features all laid out in advance and that list can never change. Such a pre-enumerated list carried down through the ages seems to lack the elegance that you so admire in natural selection, but whatever.

    But the common idea of evolution, when used in contexts like this, is that progressive genetic changes are occurring causing a gain of a trait that did not previously exist in the genetic code. This is never the case.

    It is frequently the case, observable in the human record, in the lab, and elsewhere. New traits arise that did not exist before. Some of them are bad traits, some are good traits, and which survive is based on natural selection.

    Natural selection selects only from traits that exist, this is true and I'm glad you're comfortable with it. However there are traits that demonstrably did not exist at one time, and which later did. It's not a mystery how this happens. Mutations happen all the time. Once the mutation exists, then Natural Selection happens.

    The myth that interbreedability is the defining characteristic of a species is common, but it's a myth nonetheless.

    Well, the reality is that species is not a terribly well defined entity. Attempts to create precise definitions arise from the human desire for neat classifications, not any requirement of nature. Inter-breedability is a definition, but not one that is heavily used anymore because it fails to capture a great deal of nuance.

    So it's not a good definition, but it is a useful metric in one respect, which is that if two populations biologically can't interbreed then they are definitely different species since there's no way for genetic information to pass between them.

    Ring species are an interesting corner case because sometimes the groups at the two ends of the ring can't interbreed directly, but they are interebreeding indirectly as they hybridize with neighbors going the other direction around the ring, eventually sharing their genetic material.

    As the proud owner of a still-working but quite wonkey NES, and I can tell you that you are correct on both counts. In reverse order:

    The connector does in fact suck, and makes poor contact because of the spring design. This is basically the entirety of the problem right there. The top-loader NES doesn't have this issue like every other console didn't, and if you used a Game Genie in your NES the problem would mostly go away as well (since it was designed to make contact with the connector when the cartridge holder was up).

    Blowing definitely works, but the reason it works has nothing to do with dust or anything. It's because the humidity in your breath increases the conductivity so the crappy contact the cartridge makes will be enough.

    Once I learned this, I stopped doing focused blowing from the side to try to get non-existent dust out, and instead use big open-mouth puffs. Works much better.

A hollowpoint of the same caliber may be more likely to kill, but they are banned for every caliber because they cause severe wounds.
