There is no going back – the process is irreversible. When we pour our popcorn kernels into a popcorn popper, the is no way to know which will pop first.And once that first kernel pops, it will never be a kernel again..is forever changed! ) Teaching example using popcorn to teach radioactive decay "A variety of a chemical element (strictly, of one particular element) which is distinguished from the other varieties of the element by a different mass number but shares the same atomic number and chemical properties (and so occupies the same position in the periodic table)." That definition may not mean anything to them.Radioactivity and radioactive decay are spontaneous processes.Students often struggle with this concept; therefore, it should be stressed that it is impossible to know exactly when each of the radioactive elements in a rock will decay.If, in fact, the drug traces were found to be as old as the mummies...Then it would seem further investigation is warranted...
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
The question of Adam and Eve has come up often in the discussion of the relationship between science and faith.
While it has no impact for the unbeliever from the science side of the question, it is a serious issue from the Christian side of the question. John Collins’s recent book, , published just this month.
Nor is it surprising that that pastors in the Northeast are most likely to strongly agree that God used evolution to create humans (25%) but pastors in the South are least likely to strongly agree (8%), or that education plays a role, with more highly educated pastors somewhat more favorable to an old earth and evolution in general.
Others results are more surprising – like the link between age and conviction on the age of the earth.
