SUMMARY:How to be a Quantum Realist - Dr. Andreas Doering\, Oxford Univers
 ity Computing Laboratory
DTSTART:20100203T200000Z

UID:TALK22611@talks.cam.ac.uk
CONTACT:Rebecca Bowler
DESCRIPTION:The strangeness of quantum theory largely lies in the fact tha
 t there is no picture of reality arising from the theory. The Hilbert spac
 e formalism\, which is 80 years old now\, almost inevitably comes with an 
 instrumentalist interpretation (unless one is willing to accept many world
 s with their strange ontology). All statements involve measurements\, obse
 rvers\, probabilities -- we learn nothing about a quantum system `in itsel
 f'. In this talk\, I will sketch some aspects of the so-called topos appro
 ach to quantum theory\, which aims to give a new mathematical formulation 
 of quantum theory\, including a new form of quantum logic\, and allows for
  a realist interpretation.\n\nThere would be a wine reception after the ta
 lk with the guest speaker.\n\nFree for members\, £2 for non-members.
