This coverage gap lies beyond what is considered the effective range for radiocarbon and prior to what is considered the effective range for potassium-argon.This problem period may be even larger because: (1) some dating authorities believe that the effective range for K-Ar doesn't begin until about 400,000 ya, and (2) many of the older fossils are found at sites that lack the volcanic rocks necessary for K-Ar dating and hence cannot be dated by this method at all.
Yet there are still references to ESR dating as an ‘experimental’ technique, one which cannot be trusted to produce dates that are accurate or precise.
When you’re figuring out how much rope is needed to wrap around a barrel (or whatever they needed π for a few thousand years ago), knowing it out to 10 digits or more is massive over-kill. There are several proofs of π’s irrationality but they’re all fairly meandering and complicated (even for this website), although if you’re comfortable with calculus, running through them is a good exercise.
With only 32 digits of π (3.14159265358979323846264338327950), and a really good measurement of the diameter of the Milky Way galaxy, you could wrap a rope around the galaxy’s circumference that’s accurate to one atom in length. In practice (when building physical things) it couldn’t matter less that π is irrational.
Although young-earth creationists challenge the legitimacy of all of the dates obtained by the long-term radiometric methods, even evolutionists are beginning to admit that this dating gap presents a problem for them.
However, the real seriousness of this problem seems to elude them, even when they occasionally refer to it in their writings. In the past 15 years, the major focus of human evolution has shifted from the origin of "all" humans to the origin of "modern" humans, and the very time during which modern humans are alleged to have evolved from their more primitive human ancestors is the period covered by this gap.
But ultimately there are two reasons to know π out to more than a handful of digits: studying π for purely mathematical pursuits, and winning competitions. Answer gravy: π = 3.14159265358979323846264338327950288419716939937510582097494459230781 6406286208998628034825342117067982148086513282306647093844609550582231 7253594081284811174502841027019385211055596446229489549303819644288109 7566593344612847564823378678316527120190914564856692346034861045432664 8213393607260249141273724587006606315588174881520920962829254091715364 3678925903600113305305488204665213841469519415116094330572703657595919 5309218611738193261179310511854807446237996274956735188575272489122793 8183011949129833673362440656643086021394946395224737190702179860943702 7705392171762931767523846748184676694051320005681271452635608277857713 4275778960917363717872146844090122495343014654958537105079227968925892 354201995611212902196086403441815981362977477130996051870721134999999…
Evolution places severe demands upon fossils used to support it.More recently it was shown that π cannot be the solution of any polynomial (with rational-numbered coefficients), and there’s been a lot of work on whether or not random sequence of numbers shows up somewhere in π (if you’re willing to look long enough).To date, what with computers and clever mathematicians, π has been calculated out to several trillion digits (based entirely on its extremely simple definition, and buckets of math).This gap is from about 40,000 ya (years ago) to about 200,000 ya on the evolutionist's time scale.It covers roughly the period known as the Middle Stone Age (MSA).This paper discusses areas for which this is true and suggests what should be done to convince skeptics.
