I mean in the traditional sense I know you can probably be a polymath in any variety of subjects. But I refer to those that are philosophy, mathematics and physics which naturally lead to engineering and probably computer science. Now I don't mean a complete expert in each of these fields but someone who is talented enough and can use what I mean in my opinion the nexus which is mathematics. Then extends outwards into the other fields slightly and can use this culminated knowledge to spot relationships, innovate or invent something. Or is there just too much knowledge in today's society for this to be possible. I am fully aware of the strengths of specialization but we got lots of specialization and it depends on how each of them specialists interect that stuff gets done. What about the glorified middle man? I suppose engineers are polymaths in a sense I mean they gotta extrapolate the practical applications of what the others discover.
