pg33 Overlapping of laws at different levels (part 2 of 3)


2. If we wish to recognize a molecule, or a dog, as a special individual object which follows its own chemical laws, or biological laws, then we have to give up treating them as particles following physics laws.  Because chemical laws already contain a high percentage (but not 100%) of physics laws, it would be overlapping each other if both of them are applied simultaneously.  The little percentage not governed by physics laws is due to drop-offs, which cannot be calculated.  If there were no drop-offs, applying chemical laws simultaneously with physics laws should pose no problem, as chemical laws can be translated completely into physics laws.  But when drop-off happens, we can choose only one set of laws at any moment. 

When choosing to recognize molecules and use chemical laws, there are two ways to deal with it.  The first way is to treat molecules as a conceptual structure because its component atoms can be dropped off and replaced by similar atoms from time to time.  This causes an uncertainty which is beyond control of the chemical law, as the law is acting on the conceptual structure rather than on fixed atoms.  This is the same to biological laws when we consider a dog not as a collection of particles or molecules, but as an individual animal.  Obviously, the uncertainty in a chemical law is larger than the uncertainty in the physics of quantum mechanics and the uncertainty in a biological law is even larger than the uncertainty in chemical laws.
