Physics Is (NP-)Hard

Posted by Soulskill on from the assume-a-spherical-traveling-salesman dept.

An anonymous reader writes "New research at the boundary of physics and computer science shows that determining the dynamical equations of a system from observations of its behavior is NP-hard. From the abstract: 'The behavior of any physical system is governed by its underlying dynamical equations. Much of physics is concerned with discovering these dynamical equations and understanding their consequences. In this work, we show that, remarkably, identifying the underlying dynamical equation from any amount of experimental data, however precise, is a provably computationally hard problem (it is NP-hard), both for classical and quantum mechanical systems.'"

  1. The little boat of Simon Peter. by JCPM · · Score: -1, Offtopic

    The symbol of Simon Peter is: "a little boat (and ... great fisherman!)".

    The symbol of the 2 metal keys like this http://upload.wikimedia.org/wikipedia/commons/8/81/Emblem_of_the_Papacy_SE.svg is the symbol of fake authority for auto-profiting itself this pontifical harlot of Rome for nearly 2 millennia. And the announcement of the fake authority and of that is beneath it is abomination.

    Jesuchrist said that he gave him the keys, but never said that of the 2 metallic keys.

    The question now is, is Simon Peter in his place? (after of his possible martyrdom). If not then somebody will have to go there and to occupy its position, perhaps i'm, namely that who starts is who ends, that means that, the last body that is positioned should be the first, and all the saints who follow him will be saved.

    Rome is not the rock you were looking for on which Jesuchrist will build the Church, nor the place to be accessible to the Kingdom of Heaven. Simon Peter knew it, i might do, but I will have to try it with my faith that has guided me. If you follow me then I'll lead the place for the saints can access to the Kingdom of Heaven.

    During all that time, the fake authority has never had access to the Kingdom of Heaven, because otherwise if any, how is it that they do not know the aramaic that also is the first (native) language of Simon Peter?

    Holy gentle, gentile saints, do you want to see the living angels? You will can have a chance if you abandon the evil current empire and follow me.

    From now, the current symbol is: "a little boat", and not that of Rome and not that from Rome.

    JCPM: i did decipher it! Now it will be my time of reacting myself for acting myself divinely!.
