LMU FAQ Bohmian Mechanics
28 episodes - English - Latest episode: over 5 years ago -Bohmian mechanics, also ofter referred to as the de Broglie-Bohm theory, is a theory of quantum phenomena based on a particle picture. It provides an ontologically clear and mathematically precise framework from which the entire quantum formalism can be deduced. This series covers some of the most frequently asked questions about Bohmian mechanics. It also addresses widespread criticism, misconceptions and confusions in a concise way. For further details we refer to our introductory lecture on Bohmian mechanics, also available on iTunes U.
