No theory of reality compatible with quantum theory can require spatially separate events to be independent.Collection: Independent
Long may Louis de Broglie continue to inspire those who suspect that what is proved by impossibility proofs is lack of imagination.Collection: Inspiration
The concept of 'measurement' becomes so fuzzy on reflection that it is quite surprising to have it appearing in physical theory at the most fundamental level ... does not any analysis of measurement require concepts more fundamental than measurement? And should not the fundamental theory be about these more fundamental concepts?Collection: Reflection
Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.Collection: World
It is difficult for me to believe that quantum mechanics, working very well for currently practical set-ups, will nevertheless fail badly with improvements in counter efficiency.Collection: Believe
