Erwin Rudolf Josef Alexander Schrödinger ForMemRS HonMRIA (UK: /ˈʃrɜːdɪŋə, ˈʃroʊdɪŋə/, US: /ˈʃroʊdɪŋər/; German: [ˈɛɐ̯vɪn ˈʃʁøːdɪŋɐ]; 12 August 1887 – 4 January 1961), sometimes written as Schroedinger or Schrodinger, was a Nobel Prize–winning Austrian and naturalized Irish physicist who developed fundamental results in quantum theory. In particular, he is recognized for postulating the Schrödinger equation, an equation that provides a way to calculate the wave function of a system and how it changes dynamically in time. He coined the term “quantum entanglement”, and was the earliest to discuss it, doing so in 1932.

A craton ( /ˈkreɪtɒn/ KRAYT-on, /ˈkrætɒn/ KRAT-on, or /ˈkreɪtən/ KRAY-tən; from Ancient Greek: κράτος kratos “strength”) is an old and stable part of continental lithosphere (the Earth’s two topmost layers, the crust and the lithospheric mantle). Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates; the exceptions occur where geologically recent rifting events have separated cratons and created passive margins along their edges. Cratons are composed of ancient crystalline basement rocks covered by younger sedimentary rocks. They have a thick crust and deep lithospheric roots extending several hundred kilometres into Earth’s mantle. In simpler terms, craton is a layer of the earths crust on that has been almost unchanged through all of history. This crust consists of shields and platforms. Shields are made of basement rock and are visible, while platforms is the portion not visible made up of sedimentary rock.
