      Managing online materials for large classes can be time-consuming and error prone. In particular, it can be challenging to manage long lists of students, lecture progress, and auditorium schedules as these often change on ...
    • A solution of the Mitra Paradox 

      Grøn, Øyvind (Journal article; Peer reviewed, 2016)
      The “Mitra paradox” refers to the fact that while the de Sitter spacetime appears non-static in a freely falling reference frame, it looks static with reference to a fixed reference frame. The coordinate-independent nature ...
    • The Accessibility of MOOCs for Blind Learners
