Hey, Patrick...good to hear from you again...how's the fishing?
I take from your response that you think that I believe that a Chemist is not a scientist unless he publishes; and a "scientist" is not a scientist if he does not publish. To the contrary; what I was trying to convey was that a Chemist or a Biologist or an Astronomer have some entitlement to the title "scientist"; however, the expertise they may exhibit in one particular area may differ greatly, although they all have the basic tools to understand the issues. I would not limit the title "scientist" exclusively to a person who does pure research and has lots of publications...I would however, prefer Einstein as an expert witness on the properties of light, over say Michael Crighton.
