I'm reading about Quantum Monte Carlo, and I see that some people are trying to calculate hydrogen and helium energies as accurately as possible.
QMC with Green's function or Diffusion QMC seem to be the best ways to converge on th... |

Many linguists think that broad cross-linguistic comparison is sometimes “too shallow”, and that instead, language universals can be detected only if they are based on “in-depth”, “abstract” and “detailed” analyses. Here I give reasons to think that this is the wrong approach. This discussion is not new (cf. Comrie 1... |

Is heff=hgr hypothesis really consistent with TGD inspired quantum biology?
The life of theoretician trying to be worth of his salt is full of worrying: it is always necessary to make internal consistency checks. One of the worries is whether the hypothesis heff=n× h = hgr = GMm/v0 is really... |

That's too steep for me. Especially just to learn if the tool is right for me.
