>Any physical model gained by fitting data which purports to be faster than those based on a computable approximation of the laws of physics is so constrained.
Constrain the model so that there aren't any superfluids, semiconductors, plasmas, metals or Bose-Einstein condensates and you can still simulate any medicine I know of.
I meant metals in the solid-state physics sense, with the oceans of electrons and band gaps and stuff. You can keep your monatomic ions (which are crucial for biology in many ways).
