No doubt there. When I was at college studying civil engineering, the explanation about the idea that it was a non-scientific field of study was that even though you do need a well versed background of scientific comprehension, you arent really doing any sort of experimentation type activities or testing concepts, at least not in the sense of proving a hypothesis. As my instructor used to say "your'e pouring concrete kid no splittin' atoms". Frankly, if one wants to consider it a scientific field, I can see it and wouldn't argue it. I agree, Bill Nye knows how things work. If I recall correctly, he studied under Carl Sagan and worked for Boeing for a time. I don't like how people flippantly call him an "actor". By explaining science to children (myself included), he's done more for scientific progress than most.
