Isn't Sandia a weapons laboratory?
To: FormerLurker
Yes. And I'd say that was a pertinent observation, actually. Who knows what we're not being told?

The researchers created an artificial cell membrane made of "phospholipid bilayers" -- rows of long molecules that, like empty soda bottles bobbing on water, self-organize into an orderly heads-up/tails-down formation. . . .
The process was performed repeatedly on the same membranes with the same result -- reversible reorganization.
Astounding numbers of people will tell you this can't happen without The Designer. Oh, wait! The experiment had a designer. Yes, but the designer of this experiment doesn't tell the molecules where to go.

Although producing such chemical recognition events on an artificial membrane is not an achievement in itself, examining them with such fidelity is, says Sasaki.
Tide or Cheer, water and Mazola corn oil display some of the same "self-organizeing" ability.

The deliberate misconstruction of the Second Law used to support creationism rules out many things known to occur and is clearly fallacious.

That is quite a bit different than a house crystallizing out of a load of bricks, or a cell organizing itself from a soup.

True, there are no chemical reactions in the crystallization of sugar from solution. That makes it qualitatively different from the processes in the main article or anything in abiogenesis.

There are still people who wittingly or not tout a version of the 2nd Law of Thermodynamics that characterizes any seeming increase in "order" impossible without intelligent direction. They remain wrong.

so, can i whip up a batch of gold with this stuff...or maybe do a weird science thing?

</sarcasm>
Transmutin' elements is a nuclear reaction thing.

2nd Law of Thermodynamics that characterizes any seeming increase in "order" impossible without intelligent direction. They remain wrong.True. However, it does "prohibit" some order/disorder from "naturally" occuring. Can you uncook an egg?

Thermodynamic entropy isn't logical entropy. It doesn't explicitly prohibit anything about order and doesn't talk about "natural" versus "unnatural." That's because if you can do something, it's natural. (If you can't do it, it may be unnatural or it may just be hard.)
To: VadeRetro
but the standard 2nd Law isn't about order.You got it. It is about heat flow.
