Carbon dating mistakes
Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.
Ph ET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!
And it has been close to a hundred years since the uranium-238 decay rate was first determined.As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.The isochron techniques are partly based on this principle.The use of different dating methods on the same rock is an excellent way to check the accuracy of age results.
