in the atmosphere! This argument was popularized by Henry Morris ( 1974,.164 who used some calculations done in 1968 by Melvin Cook to get the 10,000-year figure. We can also explore this issue from first principles. N ( t ) is the quantity that still remains and has not yet decayed after a time t, t 12 is the half-life of the decaying quantity, is a positive number called the mean lifetime of the decaying quantity, is a positive number called. The water level just sits there even though the hose is going full blast. It is painfully obvious that. The curve is roughly 180 degrees out of phase with the C-14 curve. ( Strahler, 1987,.251). Samples from top to bottom of a peat bog gave reasonable time intervals ( Science, vol.200,.11). In a first-order chemical reaction, the half-life of the reactant is ln(2 where is the reaction rate constant.

( Brush, 1982,.42) Since we are dealing with millions of C-14 atoms in even the smallest samples, the amount of C-14 remaining with respect to time will be an excellent approximation of an exponential decay curve. The earth's magnetic field seems to have the greatest effect on C-14 production, and there is no reason to believe that its strength was greatly different even 40,000 years ago. Creationists don't want their readers to be distracted with problems like that - unless the cat is already out of the bag and something has to be said. Hovind (R1 The atmospheric C-14 is presently only 1/3 of the way to an equilibrium value which will be reached in 30,000 years. "Assignment #2: Data, Simulations, and Analytic Science in Decay".
