Chapter 1: Scientific Attitude and Method, Importance of contributions…

- - - - is the scale of objects that are large enough so we can see them with the naked eye
        
        for example people, chairs, planets
    - - Is the scale of objects than are so small we cannot see with the naked eye
        
        for example atoms and molecules
    - - is the scale of objects between microscopic and macroscopic
        
        for example bacteria and virus
- - - - We need to define a question about how and why it happens that way
    - - We need to observe a natural phenomenon that we are curious about
    - - We need to construct a hypotheses and our own theories with the scientific attitude
    - - We finally test and probe our theories and hypotheses
    - - And we draw our results and conclusions about our different test. If it fails we need to think more theories and the process repeats itself
