One of the most important is the cluster decomposition property: roughly speaking, a property intended to capture the fact that the outcome of experiments at Fermilab is independent of whatever might be happening in the accelerator tunnel at SLAC. Steven Weinberg went so far as to call it a foundational requirement of all experimental science. However, the statistical independence required by cluster decomposition is in tension with the long-range correlations characteristic of entangled states. Nevertheless, something very much like Weinberg’s transcendental-ish claim is probably correct but appreciating that requires disentangling the role of the cluster decomposition property from its standard mathematical presentation and elucidating a delicate relationship between the cluster decomposition property and the ubiquity of entanglement in quantum field theory.</span><o:p></o:p></p><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black'> </span><o:p></o:p></p><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><b><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black;border:none windowtext 1.0pt;padding:0in'>Can’t make it in-person?

Bohr deemed the quantum postulate, or “wholeness” of interaction between agency of measurement and atomic system, to call into question a core epistemological distinction between subject and object familiar in the concept of ‘observation’ from everyday life and classical physics. Re-conceptualizing that distinction led to redefinition of the term ‘phenomenon’, a corresponding non-representationalist account of the wave function, and to situating the notion of objectivity within “conditions of the possibility of unambiguous communication”.</span><o:p></o:p></p><div><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black'> </span><o:p></o:p></p></div><div><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><b><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black;border:none windowtext 1.0pt;padding:0in'>This talk will available online through the following:</span></b><o:p></o:p></p></div><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black'>Zoom - </span><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:#2D8CFF;border:none windowtext 1.0pt;padding:0in'><a href="https://pitt.zoom.us/s/99943669767"><span style='color:#2D8CFF'>https://pitt.zoom.us/s/99943669767</span></a></span><o:p></o:p></p><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black'> </span><o:p></o:p></p><p class=MsoNormal style='line-height:150%;vertical-align:baseline'><span style='font-size:12.0pt;line-height:150%;font-family:"Arial",sans-serif;color:black'>YouTube at <a href="https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg" title="https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg"><span style='border:none windowtext 1.0pt;padding:0in'>https://www.youtube.com/channel/UCrRp47ZMXD7NXO3a9Gyh2sg</span></a></span><o:p></o:p></p><div><p class=MsoNormal style='margin-bottom:12.0pt;line-height:150%;vertical-align:baseline'><o:p> </o:p></p></div></div><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
