What is Study? If someone asks me "what is Study?", I will answer "Refined curiosity.". It is because that people didn't want to be born into this world. This unkind world doesn't even explain why we were born or why we have to live. Just one day, we were born and began to live. So, living in the first human beings itself would have been the reason of life. The first human beings had an irrational anxiety about death. Eventually, after several generations, human beings would get used to this world. The most important of these adaptations was the agricultural revolution. After that, some human beings were not constantly fighting for survival. Some of those human beings asked themselves "why must we live?". These questions became bigger and reached the questions that "why does nature have these forms?" or "why do human societies have these forms?". So I think that these questions or the answers to these questions made Refined curiosity called Study. ps. I think Study is a generic term for physics, astronomy, biology, etc. Is that true?
