Ah, I suppose you believe that theoretical physics -->
  electronics --> chemistry --> life --> biology --> neuroscience
  --> rational thought --> theoretical physics and it's just a
  matter of a Master Theory in theoretical physics to tie it all
  together once and for all, so all the divergent sciences can
  disappear and become One Science. Something like that? Modern
  mythology. There's a reason why there's many sciences. They
  don't reduce into each other.
