What is the collapse in Bohmian mechanics?

Update: 2018-03-13

Description

9. In standard quantum mechanics the wave function of a system collapses upon observation. I always thought the collapse of the wave function was something essential. In Bohmian mechanics the wave function always evolves according to Schrödinger's equation and never collapses. How can that be? What is the collapse in Bohmian mechanics?

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