An addition I'd like to make is that this circle is a high dimensional sphere (>300 dimensions IMHO in our current age). Another one is that an alternate representation of this circle can be made by having theta as the x axis, and r as -y. In this representation, a PhD would sort of look like a T: a horizontal bar for general knowledge, and a vertical one going deep down for the PhD. That's the T shape Valve refers to in their handbook [1]. Enough generic knowledge to communicate with your peers, and a deep enough specialty to make an impact. Other areas of specialty would make it look like paint-drip. I believe such a map can be build for an individual through a series of ML-chosen Questions and Answers (ML because this is the tool to explore that high dimensional space), but I don't have time to try to build it :/ I believe one could also assign economic value to some paint-drip patterns. The biology + deep learning paint drip seems to be very hot right now.
