It's at too fine a level there but that's nice to see the
   formulas - been a while. I think you'd get better answers in the
   'math of chemistry' rather than standard math. and even
   chemistry is too low a level - I think biochemistry is likely a
   better option, combined with cognitive psychology as they can
   use the scans and statistical analysis together. Pure math+pure
   physics is too low-level, although it can be a supporting tool
   in investigations.   'math of emotions'
