I'd prefer not to discuss this issue anymore though. I can imagine so.........

quote:Not all of the K40 is the kind with a short half-life. How the potassium is made in the magma is a good question which I don't know the answer to? In the paper they give a combined half-life for K40 of 795 years, so it isn't likely depleted in 1 day's time. Perhaps they failed to mention that the k40 atom would be a second stage of decay. I believe they did exactly that?!

Enough, I didn't expect a debate, nor do I desire to win one now This isn't surprisng. You seem to be completely out of your depth here, and not even able to see just how ludicrous the Common Sense Science people are. Take this example, their spinning ring model for elementary particles:
quote: The problem is that anything that rotates is accelerating. Nothing can rotate without accelerating. And accelerating charges radiate electromagnetic energy. If elementary particles had charges that were rotating, they would be radiationg energy; not only do we not see any energy being constantly radiated by each and every atom all the time, but by losing energy the rotation would have to stop. This was a real problem with the Bohr model for the atom -- the one that pictured electrons rotating about the nucleus like a tiny solar system. That is why the Bohr atomic model had to be discarded. This "spinning ring" model has the same problem.

How the potassium is made in the magma is a good question... It isn't "made" there. It was made in a star (or a couple of them) that contributed dust to our star system when it coalesced 4.6 billion years ago. It got collected into minerals when our planet formed, and melted into magma at some time since then.
Perhaps they failed to mention that the k40 atom would be a second stage of decay. "Second stage of decay" from what, pray tell? Scandium 44 won't hunt - it decays by electron capture. Spontaneous fission of strontium-80, maybe, with all the atoms splitting evenly? I wonder why the nuclear physicists since the Curies never noticed that? Oh....'cause it doesn't happen.

I notice you've dropped any pretense of having defndable claims.
No, I don't agree with the assumption the xenoliths are old They're older than the lava flow. And their age is not an assumption. It's a measurement.
I have rational ones; I assume you have yours unlike your other paranoid opponents. Are yours secret?
I checked out the article and wasn't very impressed. Why not? I find it impressive that 70% of recent lavas give accurate K-Ar dates and the remaining 30% have small errors. What's unimpressive?
Granted you guys got really lucky with neo-Roman city of pompeii, but given it's stone structures, I would say it isn't as old as the argon-argon date. Boy, are you confused. The date is for the lava that covered Pompeii, not the city's structures.
so I have to give you credit for defendy the crappy method of Potassium-Argon dating decently. Alas, I can't give you or the YECs any credit for attacking any kind of radiometric dating; they're frauds, and you are at least awesomely ignorant of the field and have no basis for any evaluation.

Here is a list of their papers that you can purchase. But, strangely enough, there is no indication of where they were published (if they were ever published, besides this website), nor do they have abstracts associated with them. I have a strange feeling that these aren't scientific papers.
- Wow! Did I call it or what? Here is their page of recommended links. Except for their own site, every one of these is a creationist site. Heh, even that moron, Walt Brown. If these guys are going to put in a plug for Walt Brown, how can we take anything they say seriously? And there is a site presenting dinosaur and human footprints together! Although Common Sense Science doesn't itself present itself as a creationist website, this page (and the constant mention of "Judeo-Christian world-view" on other pages) makes it difficult to determine whether these people are just a support organization for creationism, or whether these people can't really understand the picture that modern science presents to us and are sincerely trying to extricate themselves from their intellectual dilemma. Edited by Chiroptera, : Really bad typo.

If you look, Thomas G. Barnes (daid, thank God) was an ICR Creationist and the First Dean of the bad joke called the ICR Graduate School. Aslan is not a Tame Lion

While I agree the spinning ring idea is crap.... Which makes it strange that you find their conclusions interesting since this spinning ring idea is the very foundation of their theories and the basis of their conclusions. -
...we see EMR(electromagnetic radition) from atoms all the time. If by "all the time" you mean "when placed in an external electromagnetic field" (or some other perturbation) then, sure; after all, we do need a source of energy for that electromagnetic radiation. But an atom just sitting there, minding its own business, without any perturbations (like an external electromagnetic field) will not be emitting any electromagnetic radiation. After all, if it did then we would have a source of new energy, a violation of the Law of Conservation of Energy.

They're eccentrics. They sure are! -
What did you expect? I dunno; you are the one who brought them up as if they had something relevant to say. -
You are very cocky too. No, just easily amused by clowns. I find the Keystone Cops funny, too. - Added by edit:Speaking of Klown Science, I see that it's John Davison's birthday today.

I wonder if there are details which are left out. It could be because my background in physics is admittedly weak, but I can make sense of every number in the chart and document. They could also be understating the evidence by not mentioning every measurement. It happens. I don't see any evidence that the authors of the paper have taken ANY measurements. They are simply proposing a theory and computer model, and showing the results, along with tabulated data.
And if the potassium and argon was made in magma, it would be hard to date it at all accurately. Not true! When the molten magma solidifies and crystalizes, initial Ar is pushed to crystal grain boundaries since it cannot chemically bond in a crystal structure. The 40K that IS incorporated into the crystal lattice slowly decays, leaving 40Ar stuck in the crystal lattice. The 39Ar-40Ar method is able to distinguish between Ar that is at grain boundaries and Ar that is trapped within the crystal lattice, so it gives accurate dates even in this case. Someone else has already posted links to some experimental data for this.

It really helps moderators figure out if a topic is disintegrating because of general misbehavior versus someone in particular if the originally non-misbehaving members kept it that way. When everyone is prickly and argumentative and off-topic and personal then it's just too difficult to tell. We have neither infinite time to untie the Gordian knot, nor the wisdom of Solomon. There used to be a comedian who presented his ideas for a better world, and one of them was to arm everyone on the highway with little rubber dart guns. Every time you see a driver doing something stupid, you fire a little dart at his car. When a state trooper sees someone driving down the highway with a bunch of darts all over his car he pulls him over for being an idiot. Please make it easy to tell you apart from the idiots. Source |
