I've never delved deeper into this but I'm still curious: do I need to be enrolled in a PhD to publish scientific papers?
I have a MSc but I regularly read research papers of not-so-great-a-quality and think "I might write better stuff than this". It doesn't happen with the majority of papers but the point is: I don't think those authors are all smarter than me.
How does a 'private citizen' not enrolled in any PhD course publish a research to a journal?
