But what do cold temperatures do to those forces? Nothing. We've tried.
Extreme cold makes metal brittle, for example Chemistry and nuclear physics are very different.

False. That one's true (but, like most of his outpourings, irrelevant).

Wouldn't you also need patience, lots of patience?

Wouldn't you also need patience, lots of patience? Yup, but not as much as for the ingrowth technique. And many scientists have exactly that patience. Call for an improved set of decay constants for geochronological use:

That's making a claim that it is possible. It isn't.

Except that we KNOW that exponential decay matches the evidence and linear decay doesn't.

Hasn't been done, OS? You've done a literature search and have a bibliography of all proton bombardment studies ever tried?
I thought not. And what, exactly, is the relevance of proton bombardment to carbon dating anyway? I hope that you don't expect proton storms wherever you live - they sound unhealthy to me.

False. That one's true (but, like most of his outpourings, irrelevant). You tell me how the Geiger counter measures the mass and composition of the source and I will agree with you. Without having some idea of the number of radioactive atoms involved, measuring the number of decay events won't tell you much other than the source is radioactive ... it won't even tell you what isotope of which element is involved. IIRC you posted some links to articles on the determination of half-lives ... did any of them do it by just counting decay events? abe: OH SNAP:

OS -- have you researched isotropic fractionation and the reservoir effect, as I suggested in previous posts?
I think this would clear up a few (of many) misconceptions.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge. Belief gets in the way of learning--Robert A. Heinlein How can I possibly put a new idea into your heads, if I do not first remove your delusions?--Robert A.

I don't have good reason to say dating dinosaur bones with the method is terrible. Why would you ever think of dating something that is >65 million years old with a tool that only goes back 50,000 years? That's like trying to use a 12 inch ruler to measure the distance to the moon--it just doesn't work.

I thought not. You thought wrong. I have done everything I can think of so far, but there are few articles on it. Doing this is quite uncommon. ??

Dating dinosaur bones with carbon-14 has EVERYTHING to do "with the range of the method." You can't do it. It isn't done.
The range of a yardstick makes it an inappropriate tool to measure the distance to Jupiter. For exactly the same sort of reason, C-14 dating is useless for 65,000,000 years. "The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken

RAZD writes: No, you really don't. ... Except that we KNOW that exponential decay matches the evidence and linear decay doesn't. Actually for short lived radioisotopes you can plot decay events versus time (adding a watch to the Geiger counter) and you end up with an exponential curve ... ... or you can plot the relative amounts of, for example, 14C compared to 12C in samples of known age against their ages and you end up with small variations around an exponential curve, with the variations caused by variations in 14C in the atmosphere from the (known) variation in solar cosmic rays. This has been done for 50,000 years of samples of known age (such as tree rings and lake varves). Curiously, the comparison of 14C/12C levels in samples of known age is what the whole issue of 14C and tree rings (or varves) etcetera is about -- trying to determine the original levels of 14C/12C in the environment at those different ages and thus make 14C dating more accurate. A straight line fails to fit the data within the first 10% of the half-life.
... It is a thermodynamic calculation, ... Calculations are used based on well known physics and actual evidence -- see JonF post Message 380 for SOME of the examples available from actual published scientific research.
... and there is nothing to suggest isotopic concentrations don't have full lives. Except that it doesn't match the evidence and "full lives" is a non-sense term: every radioactive isotope would have an infinite "full life" by definition ... or is your understanding of this even more incredibly uninformed (counter-informed?) than your other issues? Can you tell me what a tree ring is? Just wondering. Enjoy. Edited by RAZD, : ..by our ability to understand Rebel☮American☆Zen☯Deist ... to learn ... to think ... to live ... to laugh ... to share.
