On the Relations Between the Languages of: Mathematics, Physics and Didactics of Physics in Terms of the Theory of Metalanguages
As the didactics of physics, structure and methodology of physics and physics itself are inseparable, it turns out that – in the first approximation – the language of the didactics of physics (LDP) consists of the language of physics (LP) and its metalanguage (mLLP): LDP ≡ LP + mLLP. On the other hand the language of physics itself consists of the language of mathematics (LM) and its metalanguage (mLLM): LP ≡ LM + mLLM. The final conclusion is that the language of the didactics of physics consists of the language of mathematics and of the hierarchy of its metalanguages: LDP ≡ LM + hierarchy mLLM. This hierarchy has two orders.
