Is it true that Phds in other fields can be much less work? i.e I over herad a guy talking on the tram about his Phd which he only started one month ago and had already done 30,000 words. However he did have a lot of background knowledge prior to starting it. It was on the current Middle Eastern situation.your question is hard. but i say, as in the nba, go with the love you feel for the topic. a phd is indeed a long hard road, so it is essential to be committed to your topic and to have a supportive advisor. i chose based on the attraction i felt for the material presented in lectures, and my ability to understand and connect with the advisor who taught the course. i still had to pass through more than one such experience before i found the maturity and commitment to carry through the job of completing a thesis.
ideally you should feel, this material is speaking to me, and this lecturer is speaking to me.
The word length is 100,000 words for a complete thesis? But how would you count the equations and symbols? Surely they would factor into the word count?
