Phil Thank you for the information A background in optics and particularly in materials is important in understanding CF If you are serious about the balance in WP reflecting a neutral position or that of the populations then you need to recognize that these  positions may be in serious conflict Also recognize those positions are shifting quite rapidly and WP is supposed to shift with them I will try to work with you to help make that transition in WP as correctly as possible  I have provided above in Proposed change to the introduction what I believe to be answers to the reasons that you have expressed for reverting my earlier attempts to add new and pertinent data from an adjacent field I have tried to include quotations and specific points of reference in the citations since you do not have the time to read them or the rest of the CF literature to see what is common in the field and what is WPOR If you are not able to agree with my arguments then we will need to proceed to the Original Research Noticeboard If you are specific in your objections I can address them If not I have to guess where you are coming from and end up spending time building a wall of text in Hipocrites complaint to justify my inclusions against a  word edit
