    1998_Armageddon

    Movies that deal with the Armageddon caused by the impact of a meteorite on earth have the great advantage that they can almost completely define the scenario – until now almost no references exist how such an event would occur in reality.

    A World without History

    BURNET_1680_Sacred_Theory

    Tat: “Does the earth seem to you unmoving, father?” Hermes: “No, my son. It is the only thing full of movement, and at the same time stationary. Would it not be absurd for the nourisher of all things, the producer of and begetter of all, to be motionless?…[]“ “Corpus Hermeticum” 100-300 A.D. According to Aristotelian [...]

    Geology Will Rock You !

    The music-video “Mutual Core” (2011) by Björk, starring hot tectonic forces and sensual strata, is by far not the only examples of how geology and paleontology could inspire musicians and songwriters.
