Historical methods of dating data Rough sex for free no creditcard
Using new samples of feldspar and pumice they ‘reliably dated’ the tuff at 2.61 million years, which agreed nicely.
Later, this date was confirmed by two other dating methods (paleomagnetism and fission tracks), and was widely accepted.
" Every result is based on numerous unprovable assumptions.
By the historical method we know that the Treaty of Waitangi was first signed on 6 February 1840.
Then Richard Leakey found a skull (called KNM-ER 1470) the KBS tuff, a skull that looked far too modern to be 3 million years old.
So Curtis and others redated the KBS tuff using selected pumice and feldspar samples, and obtained an age of 1.82 million years.
Every other method that is based on making measurements in the present amounts to, "What age would you like?
“See how easy it is to calculate the age of something scientifically? “In order to calculate an age you made assumptions about the past.
Every dating method that scientists use works exactly the same way. You assumed the rate had always been 50 ml per hour and that the cylinder was empty when it started. “Then, when I told you the correct answer, do you realize what you did?
I asked, ‘How long has the water been dripping into the cylinder?
’ Immediately someone called out, “Six hours.” “Good. ” “By dividing the amount of water in the cylinder (300 ml) by the rate (50 ml per hour).” “Excellent,” I said.
It was clearly marked so my audience could see that it held exactly 300 ml of water.
