Density of classical states in quantum theory @genneth: DFT is exact only theoretically. noone has ever found correct functional. it is like telling that using configurational integral is exact solution, but it is just rephrasing the problem. |

Density of classical states in quantum theory DFT is an approximation often called an expensive RNG. I talk about some precise stuff, exact wavefunction. Not those coupled cluster or PIMC approximations. |

How to find that a molecule has zero spin? Pauli exclusion priciple implies only that only 2 electrons can occupy 1 orbital. Energetic degeneracy of more distinct orbitals can cause some orbitals to be only singly occupied. There is also a Hund principle of maximum multiplicity (electrons having same spin repel less each other resulting in lower energy). So not all atoms/ions/compounds with even number of electrons have zero spin. |

What formulae for calculating fluid pressure change involves these parameters? It seems to be volumetric flow. I do not see viscosity in the formula. |
