Re: What are "principles" in science?



Hi all-
I agree with "stupidity". More precisely, the statement seems to
claim the equivalence of three, otherwise undefined, expressions:
chemical change,
atoms in substances are rearrangedto make one or more new substances
change in composition

Would it be appropriate to replace the word
PRINCIPLE by the word LAW?



Although there is no hard and fast rule concerning the use of the terms,
to me it sounds like an explanation and, as such, has more in common
with a theory than a law.
