  3. EU is all about no proof and ignoring experiment on SOFIA Sees Jupiter's Ancient Heat · · Score: 3, Insightful

    Personally I am attracted to the alternative Electric Universe theory because they recognize a need to back up their statements with laboratory experiments, and with theories that do have a great deal of proof behind them, such as the behavior of plasma.

    LOL.

    Electric Universe holds that the solar wind is caused by the sun's electric charge, creating a current of protons outward.

    Actual experiment indicates that the solar wind is comprised of roughly equal amounts of protons and electrons traveling outward from the sun. With no net movement of charge there is no current, and Coulomb's Law says an electric field cannot move oppositely charged particles in the same direction, both indicating (though it's really one thing, the Theory of Electromagnetism) that the Sun has no net charge.

    As one would expect from the well-verified theory of plasma behavior, the majority of which are quasi-neutral, with those that aren't being necessarily non-dense.

    So, yeah, they ignore experiments that prove their most basic premises wrong, and don't even understand the well-established theory their ideas are allegedly based on.

    But hey, I can't tell you who you should be attracted to.

    Should we be concerned that only 30% of scientists adopt a position of agnosticism towards matters of religion? Surely in the absence of reproducible evidence either way, the scientific position is to be non-committal?

    No, because even for a scientist there is a difference between the scientifically verifiable reality and personal belief.

    There's nothing wrong with a scientist having a belief. There's nothing wrong with saying "I believe the Luminiferous Aether exists" or "I believe dark matter consists of WIMPs" or even "I believe that Yahweh, God of Abraham, created the universe we see around us," and for that matter "I believe neither he nor any other God exists".

    Having beliefs is just fine. The difference is that your belief is not a substitute for nor an argument against scientifically verifiable reality. If you believe in the Luminiferous Aether, that's fine, but you have to demonstrate it with experiment before you can claim your belief is also reality. If your belief is not subject to experiment (i.e. "God exists"), then your belief it must remain.

    Scientists are humans, and humans believe things. I personally think we're better for it; it makes us strive for goals that are out of sight and out of reach. I'm a little alarmed by the number of people who, embracing rationality, say that you should not believe in anything that isn't empirical reality. That anyone who claims to be a scientist must always be rational. Despite that there is no evidence that a human being can be completely rational, and tremendous evidence that reason and logic are just tricks our emotional mammal brains use when convenient and discard as soon as they aren't. In other words, they themselves hold the belief that they are rational.

    Huh? The OT is part of the bible and is part of the basis of Christianity. Being a Christian REQUIRES one to believe the OT.

    Believing, and treating like a physics and biology textbook, are different things.

    Being a Christian is most importantly about believing in Christ, and following His teachings are more important than following the OT. For example, the OT says to honor the sabbath by not performing any labor. When Jesus walked around picking fruit on the sabbath, people yelled at him for not honoring the sabbath. Jesus said the sabbath (and by implication the law) was made for mankind, not the other way around.

    So when the OT says to stone adulteresses and witches, and Jesus says the most important commandment is to love thy neighbor as thyself, and to let he who is without sin cast the first stone, it's hardly being a "cafeteria Christian" to listen to Jesus.

    Besides, I've never known any Christian fundamentalist or not who took the prohibition against shellfish seriously. :P

So that's at least two full orbits, and nearly 3 if we turned Kepler on right after the exo-Jupiter passed over its star.

  9. Re:Die? on Flash Destroyer Tests Limit of Solid State Storage · · Score: 1

    I disagree. Flash memory erases whole blocks in one go (with a high-voltage pulse). It should be simple enough to check that the whole block got properly erased during the erase part of the write cycle. If not, that is a worn-out sector, and can be marked as such with no loss of data.

    Do flash drives actually do that? Read the block between erase and program cycles, I mean. I would have thought they would only read it once after the write is complete, if you were trying to detect bad blocks. As long as you didn't throw away the data buffer prior to checking if it worked, you wouldn't lose data either way. Wouldn't you have to know that the block wasn't all zeroes, or do another read prior to the erase?

    The main failure mode occurs because charge builds up in the gate oxide (the insulator between the floating gate and the substrate).

    Ah, the oxide, not the gate itself.

    (Being a software guy rather than a Flash memory guy, I wouldn't want to guess whether over-erased cells would be at logic 1, logic 0 or a mix of the two.)

    Well I'm not an expert on flash, but I know a little about how they work. In NOR flash the data line is pulled up to one, so that's the default state for any bit. There's a transistor connected to ground, and if the floating gate has a charge in it and the transistor is on, then it pulls the data line down to 0. "Erasing" a NOR flash sets all the bits to 1, and programming it sets certain bits to 0.

    The most common failure mode as I understand it is that electrons get trapped in the floating gate even after erase cycles such that it's very close to or over Vt for the transistor, so that bit would be stuck in the "programmed" state of logic 0.

    NAND memory is the opposite, the erased state is 0 and the programmed state is 1, so a permanently charged floating gate should result in a stuck-at-1 fault.

    Which, relating to the OP's question, means either way the memory wouldn't be good for much of anything. Your NAND SSD is going to fail during an erase-program (aka "write") cycle, and except in the extremely unlikely case that the pattern you were writing did not involve changing any previously stored 1s to 0s on stuck bits, then the result is going to be wrong. You could read it, but you'd be reading the wrong data.

    Asteroid impacts are fine and even very useful for wiping out stagnant populations (like the dinosaurs) and giving room for new species to develop into

    Um I'm not aware of any evidence that dinosaurs were "stagnant". They were continuously evolving to fill niches as environments changed, and exceptionally successful at doing so.

    The K-T Event was obviously "useful" from the perspective of us mammals since it gave us a chance to shine and fill niches the dinosaurs previously had. It's conceivable mammals still would have out-competed dinosaurs eventually, but anything but guaranteed. So from our perspective it was a good thing.

    But saying the mass extinctions of the past were "useful" from a neutral viewpoint because they got rid of "stagnant" groups like the dinosaurs sounds like an unjustified value judgment to me.

    Weather, seismic activity, it all plays a role. I definitely think our planet has a good chance of being reasonably unique.

    Unique, sure. Snowflakes are unique, but the differences rarely matter.

    What I'm saying is, sure there will be plenty of planets with properties that make it difficult if not impossible for life to evolve. Sure our planet has a unique set of circumstances. In between, there's a wide variety of possible planets where life could hypothetically evolve, just with a different path than ours. And so far there's little evidence that this wide gray area is unpopulated (though sadly little evidence *for* these planets, but our ability to detect those planets if they exist is quite limited).

    If you're lamenting that we didn't create and implement a realistic plan for developing a shuttle successor thirty years ago like we should have, then we're in complete agreement.

    If you're lamenting the loss of the shuttle replacement program we did actually have, then, well... You should realize that private industry is quite a bit closer than that program was, even if you assume all the delays and budget overruns that have plagued that program suddenly ceased to be.

    There is no scenario, starting with circumstances as they existed in 2009, where we weren't dependent on the Russians for some time, and where private industry wasn't likely to beat NASA to providing the same service.

Science missions are one of the first uses of their Dragon capsule (called 'DragonLab') that they're planning as well.
