Well, that's why I linked to the Wikipedia article in my prior post.quote: But the idea was you and a match in a 1ATM O2 environment. I doubt you'd come to harm.
You're probably right - after all, the solution to the Apollo 1 problem wasn't just a 60/40 oxygen/nitrogen mix, but a lowering of the pressure by a whole 9 kPa (still above 1 atmosphere, but not by as much), and a replacement of all flamable materials with self-extinguishing stuff. Of course, a match isn't self-extinguishing, but perhaps skin is...? |

From the wiki article:
quote: The fire is believed to have been caused by a spark somewhere in the capsule's 30 miles (50 km) of wiring. Due to the pure oxygen inside the capsule (which was at a pressure of 15 psi or 100 kPa) the fire was quickly out of control. The Apollo 204 Review Board determined that a silver-plated copper wire running through an environmental control unit near the command module pilot's couch had become stripped of its insulation and abraded by repeated opening and closing of an associated access door. This weak point in the wiring also happened to pass near a junction in a ethylene glycol / water cooling line, which had developed a leak. The electrolysis of ethylene glycol solution with the anode made of silver resulted in a violent exothermic reaction that ignited the ethylene glycol mixture, which in turn was able to burn in the atmosphere of pure pressurized oxygen
Now, if you rubbed yourself down in baby oil and vasoline, and struck a match in a pure O2 environment.... you might be in trouble.

Rub yourself down with motor oil and you won't need a match. But all thought would have fled at birth from someone stupid enough to perform that trick, so the point is moot. quote:
Yeah, I've gone out on a limb, but there's a reason life forms are different from non animated matter and natural selection/evolution isn't enough to explain it. All I have to do is look within and see that I am one and my corpse is a collection...hence evolves the idea of a spirit or soul. To me it is silly to think a composite has an 'individual' identity (individual means in-dividual). Has NOTHING to do with religion.
Ok, ok... I think I'm finally getting a toe-hold on this....
You are positing a "reason for life" of sorts, yes? I don't suppose that needs religion, although one pretty much follows the other in most cases.
I don't buy it. Apart from individual feelings and emotions, which we all feel, the existence of a spiritual -- call it "plane" for lack of a better word -- has yet to be proven. Nor will it ever be simply because science deals only with the corpus and not the spiritus, as it were. And the reason being for that is that one can tested and the other cannot.
I think that the Theory of Evolution alone is perfectly adequate to explain individual diversity within a species. Indeed, as individuals become more diverse, the genetic make up of their populations might, and probably will, change and this is a factor in kicking off speciation. The eastern and western diamondback rattlesnakes (C. adamanteus and C. atrox) look exactly alike in every way, to all but experienced herpetologists, but they are very different in many ways including temperment. And the tiny and rather lovely rock rattlesnake (C. lepidus) is nothing like either but yet is a pea from that same pod.

I can't prove it was. Neither can you prove it wasn't. See the point? We'll be running in circles forever. We've strong clues pointing towards the hypothesis that life was a chemical accident, though; what clues are there that point towards life not being a chemical accident? And if it wasn't, what was it, then? |

I was thinking about something along the lines of Apollo 1 when I wrote that. If STP is not high enough, though, we can stipulate that the pressure needs to be 2atm or so. That should be enough (especially once they become saturated) for a human to burn. |
Insert witty saying here. |

They are indeed. I have had all three species spend time in my madhouse, and the leps are ever a favorite. 20 inches is a big one and they are one of the world's very few viperids that feed on arthropods, notably centipedes, scorpions, and large spiders, as adults. Their venom is in small supply, but quite hot and fairly high in neurotoxins. A bite from one is extraordinary painful, but as far as I know, non-lethal to an adult human.
Anyone who does not love rattlesnakes has no SOUL!!

Before it dawned on me that to claim a composite can, by some esoteric power, have a single identity invokes the supernatural, I, too, assumed my consciousness was the result of a horde of energized particulate matter. It is not comforting to presume your essence has always and will eternally continue to exist (when sol supernova's armagedden oudda here). It was not by preference that I arrived at this conclusion.

Evolution is fine, except at the very beginning. Why life at all? Something was responsible for combining the elements of the planet into animated format. Something that liked the fluidity of water. Something that sought the energy stored in hydrocarbons. Something different from the gasses and solids we consider inanimate material.

That's just a bunch of anthropomorphising. The laws of physics are constant throughout time. The laws of chemistry hasn't changed the last 10+ billion years. Maybe the laws, as they are, just favour life given the right circumstances. On molecular scale, the combination of elements may be random. Given the mass of the elements present on Earth 4 billion years ago, life may be the result of emergent properties. If such is the case, then life was not an accident. This also leads to the conclusion that elsewhere in the galaxy is quite probable. |

Why indeed? Anyone's guess about a creator is as good as anyone else's, and none of them can be confirmed. And that, of course, brings up another question:
Why does life have to have a purpose beyond that of sustaining it's own existence, and by extension, a genesis beyond that of the casual combining of the necessary elements?
The atrox pictured is from S. TX and, at last report, is currently in a private collection in VA. I was offered it if I'd pay the shipping, but had no room. The photo really doesn't do it justice; it's one of the lighter phases and a very handsome serpent.

Our sun is not predicted to supernova.
And I don't see any evidence that anyone's "essence" (whatever that is) will continue to exist after bodily death. Because as a skeptic (not a true believer) I'd like to see some evidence supporting that claim. With billions of "essences" existing eternally, I would think there would be some evidence of their existence. |

filthy, thats a nice pic of Crotalus lepidus klaberi .
I hadn't seen a pic of one of those before.... the color is truly amazing. Beautiful animal.

At 2ATM of pure O2, you are gonna be poisoned by the O2. It is neurotoxic to humans at a pp of 2.0 ATM or higher. No need for a match.
But yes, when you start to pressurize O2 beyone 1ATM, you can get some materials to combust rapidly without any open fire to help.

Creator? Don't need no steeenkin' Creator.
Most eggheads think fundamental particles are structureless, homogeneous critters - the essence of simplicity. And they seem to be entranced by the study of material particulates - totally IGNORING ethereal construction (what is SPACE made of?). If elemental particles were structureless and homogeneous, the Universe would be a static and timeless environment. Life forms may well be ethereal fundamental elements - which react to material particles to form animated 'beings'...plankton, petunias, pollywogs, pigs and people among othersquote:

Why, indeed. Actually the meaning of life is simple "NOT DEAD".quote:

What is your body composed of? Most consider us to be carbon based, but actually by weight, we are water based. Still more interesting is that by volume our corpses are predominately SPACE. Might there be something unseen mixed in - something ethereal. Not in a different plane, not something spiritual, something completely physical - just not material (having the property of mass).
Until mankind can figure himself out - we certainly can't claim that there's intelligent life on THIS planet. |
