its because the scientist is a scientist so he need to work hard to invent something not only for the world but also for himself.
No, it is not true. A scientist can use many methods at the same time to investigate. The important thing is to eventually discard what doesn't work, and to refine what appears to work, or which can be 'proven' to work. Basically, it is all in being able to prove that the results actually work as expected, and that the results can be confirmed time after time when the experiments are repeated.
Scientists use measuring instruments whenever the can because everything cannot be observed by the senses so measuring instruments are needed instead.

Study of... without knowing what the scientists are studying, you cannot know exactly what instruments they are using.
Microscopes... But only for the really small stars.
