The wording "computer science" is too much overloaded. In French we have even less luck with the word "informatique": everything from studying category theory to using Microsoft Word is called doing "informatique"… :-/
Its as though we need a new word for these non-science related sciences.
EDIT: I thought of it! Vanity Science.
Brunel could probably not have formulated the Theory of Relativity. Einstein could probably not have "built" the Great Western Railway.
The application of science is not science.
I think the only difference is that some scientists test science, and some scientists apply science. Is a doctor a scientist or an engineer? He's both testing and applying. Semantics are sometimes pretty stupid (or usually always), and honestly that's the only reason I'm pursuing this silly argument.
Just because you use science, doesn't mean you are a scientist. The application of science CAN be science, but often isn't.
Pointless trolling is always pointless.
Scientist: A person who is studying or has expert knowledge of one or more of the natural or physical sciences.
Seems rather open ended.
What has Mark Zuckerberg done that can be called science.
You should also cite your references - The Free Dictionary isn't particularly credible.
For example you might not know that Brunell developed the design of efficient propellers for his ships.
and navvies "built" the railways Brunell just designed every thing
