Good Definitions

I just translated a part of an article by my professor into English as follows:

1. Study: knowing what somebody revealed
2. Criticism: criticizing it
3. Education: letting people know it
4. Research: revealing what nobody knows

These definitions look like pretty good to me. I was considering about which level my blog is (Study is easiest level and Research is the most difficult). I assume this blog would be categorized Study/ Education. My goal is that someday in the future, I will engage in researching somehow. When you write a report or something, what do you think which level your report is?
