‘Observational’ Quantum Cosmology

2010
Following on the appraisal presented in Chap. 2 of Vol. I, the reader may rightfully be asking: Given the framework of quantum cosmology (QC), where are the boundaries of our knowledge, i.e., what exactly constitutes these limits? What are the best directions to move in, and in particular, what predictions or (falsifiable) tests for the universe can be

Intensive Observables in Quantum Theory

Journal of Mathematical Physics, 1964
The notion of strictly intensive observables is introduced in a theory of local observables (such as that of R. Haag). If O1, O2 are two disjoint regions, then the value of a strictly intensive observable in O1 ∪ O2 is the sum of its values in O1 and O2. It is shown that energy-momentum can never be strictly intensive. This result is used to prove that
