  • Yes that’s it. Fun fact: The entropy is basically the most fundamental thermodynamical quantity, but was discoverd long after temperature and energy. If that would not be the case, we might measure temperature in eV / kByte, since the unit of temperature is energy / entropy and the unit of entropy is information.

    In a sense, the existence of the Boltzmann constant is a historical accident, because temperature and energy have been discovered after entropy.



  • Negative temperature means that the system loses entropy if you put more energy in.

    Of course that’s basically the same as the “you travel backwards in time if you move faster than light” in the sense that these are things the math does, if you put in these totally unphysical values, while the same set of rules that give this predictions say you can’t reach these values.

    Mein Kommentar war in Anlehnung an Softwareentwicklung-Zyklen. In der Alpha-Phase kann die Software schon von nicht-Entwicklern getestet werden, ist aber tendenziell noch instabil und kann komplett kaputtes Verhalten zeigen. Danach kommt die beta-Version, dann der release candidate (rc) und danach der stable release.
