Well, since you asked. :) In addition to having the necessary root vocabulary, Lojban also has well-defined ways to combine existing concepts into new words. These are strict enough that even someone hearing such a coinage for the first time can generally decipher the intended meaning. Your "thermodynamic causality", for example, I would render as "nenmalnicri'a", which can be reduced by rules to roughly "(energy-disorder)-cause", and would by default be a predicate with the same arguments and general meaning as the root word for physical cause, and perhaps other arguments if needed (probably none in this case).

Math results are neither real nor unreal; they are merely tautologies. That some map the symbols used in those tautologies onto physical phenomena and then interpret those tautologies as predictions or explanations of those phenomena is not the fault of mathematics, but of those doing the interpreting (not that this isn't a useful exercise).
