Science is reproducible, independently verifiable knowledge. Anyone can look at a “Scientific Fact” and will observe the same thing. “Scientific Facts” are also called Knowledge, or Data. One fact, a bit of information, is called a Datum. The plural is Data.
A Scientist is one who uncovers new Scientific facts, organizes existing knowledge, and can apply it to create Technology. Technology is the application of science to achieve some goal or solve some problem.
A Consultant is an expert in solving problems. This is a specialized skill itself, and involves the bringing-together of different fields of knowledge. It usually involves inventing one or more new things or ideas. Any patent rights to such inventions normally become the property of the client who hired the consultant.
