Note that the purpose of this task is algebraic in nature -- closely related tasks exist which approach similar problems from numerical or graphical stances.
Radiocarbon measurement can date organic remains up to about 50,000 years old.The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places.Students should be guided to recognize the use of the logarithm when the exponential function has the given base of $e$, as in this problem.The Judas fragments included four minute pieces of papyrus and a small bit of the book's leather binding with a piece of attached papyrus page.No part of the ancient script was altered or damaged during this process. "The calibrated ages of the papyrus and leather samples are tightly clustered and place the age of the Codices within the third or fourth centuries A.The results allowed lab experts to confidently date the papyruses to between A. D.," reported Tim Jull, director of Arizona's AMS facility, and research scientist Greg Hodgins.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.
After an organism dies, its level of carbon-14 gradually declines at a predictable pace, with a half-life of about 5,730 years.
Archaeologists precisely measure levels of the isotope in organic remains.
Forensic scientists use carbon-14 measurement in a subtly different manner.
A large increase in atmospheric carbon-14 occurred when the United States and several other countries tested nuclear weapons aboveground during the 1950s and 1960s (see Figure 1).
This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).
