It's not clear to me why the "Dualism in Science" section is relevant. Space, time, energy, and mass are all not substances. Science only deals with physical substance, which we sometimes call matter, and which comes in myriad types. "Matter" doesn't really have a specific, universally agreed-upon scientific meaning, partly because it used to imply that an object had mass, and now that distinction seems arbitrary in many fields. It's hard to say anything that's strictly accurate using the term without going into excessive detail about what you mean.
Wave-particle duality has been kind of a surprise, so maybe that would be an alternative thing to discuss in that section. - quantheory 04:23, 15 June 2010 (CDT)
