  • What Does It Mean to “Make Sense” of Physics? 
    Odden, Tor Ole Bigton (Journal article / Tidsskriftartikkel / SubmittedVersion, 2021)
    What does it mean to “make sense” of physics? It’s not a simple question. Most people have an intuitive feeling for when things do (or do not) make sense to them. But putting this feeling into words—especially actionable ...
  • What Is Light? Students’ Reflections on the Wave-Particle Duality of Light and the Nature of Physics 
    Henriksen, Ellen Karoline; Angell, Carl; Vistnes, Arnt Inge; Bungum, Berit (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
