A Scientist (科学者, Kagaku-sha) in a broad sense is one engaging in a systematic activity to acquire knowledge. They study the natural/physiological world as a profession.
There are Amateur Scientists which can refer either to the ones that study science without having it registered as an official occupation or a novice scientists who either lacks knowledge or has just begun to learn science; this can lead to dire consequences and after effects for their actions if they are not fully understood or experimented without being fully aware of the risks.
