I share your aspirations, but considering the scholasticism of academic research, you require formal accreditation to proceed with titular decorations. I don’t see why you could not personally research a topic before submitting a dissertation to a university you hopefully have access to. I don’t know any other way to achieve the rank.

I don't want work in university. I only want self-education to have knowledge equal professor.

Well, just to clarify, the term 'professor' usually means having a faculty appointment in a university or other academic institution.

But, setting that aside, you definitely do not need an affiliation with a university to pursue a life of the mind.

If you want to be a person of letters, a scholar, even a public intellectual, then go for it!

Yes you can. By studying and learning about something which no one else has done before. I remember a professor of zoology, who was expert on catching lemmings by jumping head first from some 5 meters away. They were truly amazing jumps. This technique allowed studying various rats without harming them. Especially in winter. He had very little formal education.

If no one else has done before, how can i find book for them?
