We set problems on age dating in Freshman Chemistry class. Most of them (and they're mostly not chemistry majors) don't seem to be confused.
As a computer programmer/analyst for over 20 years I know what havoc assumptions can do to application code (esp. unstated/unknown assumptions).
Identify one unstated/unknown assumption in radioisotope dating.
There are plenty of them on the creationscience site I listed which I much prefer over AIG (read that one too).
Maybe we'd all be better off if we listed our own assumptions. I think nothing would keep each person busier than spending time trying to eliminate their own assumptions and/or hypocrisy - I know bc I am a work in progress on both of these still so please forgive my errors as I do yours.
Identify one unstated/unknown assumption in radioisotope dating.
Here are several:
1. The amount of 'daughter' element present initially.
2. That the system has been sealed since it formed.
3. That the radioactive decay rate has always been the same.
