Re: [Phys-L] strange things in chem book

Yep.  Chosen by teacher before me.  So far I've been hitting it heavy and hard stating, "/This Book/ states xyz.  Many find this statement may be an acceptable guide, but NOT the way things must be done."  
Oddly, it states that there is no one single Scientific Method.

If I examined such a book, I would not adopt it.  I suspect that since you are in a public high school that
you are stuck with the book.  is that the case?
