I'm thinking about the field of mathematics. Many mathematic academics complain about teaching responsibilities and the admin matters that comes with working in an organisation. For those people, it seems research is on the top of their priority. So how about the option of researching and publishing from home? Hence one's income comes only from publishing papers in journals. In this way one does full time research while generating an income to sustain himself/herself. However is the income very small? How much would it be? Another thing is you might have to be very good to do such thing as you are most likely working in isolation. Obviously the people who can do such thing already has an equivalent of a Phd. How realistic is this option? All suggestions welcome.
