Does a measurement reveal any preexisting property of a system?

Update: 2018-03-13

Description

15. Niels Bohr always insisted upon the statement that a measurement does not reveal any preexisting property of the system, but rather produces it. Does Bohmian mechanics disprove this statement?

This series is aimed at answering FAQs about Bohmian mechanics and is mainly intended for students. The text is available at

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.
