The Researchers' Bible provides advice for obtaining a PhD, including choosing an appropriate research topic and methodology. It recommends picking a topic that is interesting, significant, and doable within three years with a willing supervisor. For the research process, it advises thinking of scenarios to hypothesize solutions, finding examples to test programs, and describing work at a higher level than code. It also stresses the importance of writing papers regularly, getting feedback, and communicating your central message clearly. The overall thesis should guide and answer what has been done and why it merits a degree.
