You have just proved your ignorance about science classification.....yes! There is such classification as historical science and operational science. You simply are not aware about it...you are just ignorant of the topic....and Real Science....is there such classification? What is the definition of Real Science...and what is Unreal Science....never heard.......can you define what is Real Science....Unreal Science....Fake Science.....I don't think they are capable of being defined....but you can see the definitions of historical science and operational science is very well-defined and everyone who reads those definitions understand what they meant. Just a little education for you: Optical images created or seen from optical instruments are different from those created by non-optical instruments.....wonder how you get your job in the company presumably specializing in imaging.....you sure you working in this industry.....if so...then I think your messages have destroyed the credential of those real scientists there!
