Another imortant issue that hasnt been mentioned yet here are dating methods. All these methods are based on differential equation models that have to be adjusted again and again to get the desired age. If no adustment is made the date given will be far smaller than the required for evos but perect for creos.
The fundamental equation is T=Ti(e^kt) Where k is the constant that is constantly changed it comes from dk/dt=kt

Re: The maths of decay.

You seem to be really confused about elementary maths and calculus. The trick is to recognize that you don't actually know what you are talking about with respect to the mathematical formulae of decay, and express yourself accordingly.
I will admit that i didnt express the variables correctly but it is also the first time that i see a negative lambda sign in there. In every textbook ive check out its a negative k. But the real problem is that youre accusing me of not knowing of what i talking about when apparently youre the one that has nly taken a basic calculus course.
Just like with the population growth model the decay model has to have its constant adjusted every certain time. Graphically if the constant is left unchanged the curve will not reach the values you want so you adjust them by taking different points on the graph to change your initial population which will eventually produce a change in the constant. you make this change again when the values obtained are starting to look illogical. More on this when i have more time
