Episode Synopsis "What exactly are the "empty" branches of the wave function in Bohmian mechanics?"

24. What exactly are the "empty" branches of the wave function in Bohmian mechanics? This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at http://www.mathematik.uni-muenchen.de/~bohmmech/BohmHome/files/Frequently_Asked_Questions_about_Bohmian_Mechanics.pdf By Christian Beck, Robert Grummt, Florian Hoffmann, Sören Petrat, and Nicola Vona. We are grateful to Martin Oelker who played the asking student, and to Nils Hansen and Stephan Kulla who filmed the videos.
