Has the Bill Nye fella ever claimed to be a scientIst himself? When looking up the word "scientist" the definition seems to be somewhat broad. There is nothing in those definitions from various dictionaries that declare a scientist must have specific educational credentials.
Nye has been given at least four Honorary Doctorate of Science Degrees from four prestigious Universities. Not just Honorary Degrees, but specifically, Doctorate of Science Degrees. That means at least four Universities have recognized Nye as an expert in science, overwhelmingly meeting the definition of a scientist as an "expert" in science. They conferred the name scientist on him, not he himself. He seems satisfied with being called just "the science guy".
So, what makes Palin or the posters in this thread qualified to change the technical and accepted definition of what a scientist is? How are they qualified to dispute the dictionary definition and four major Universities?
