But the phrase “our presence as observers” cannot be uniquely interpreted in the context of the theories within which AP is meant to be understood and applied: namely, for <i>effective</i> theories. In this talk, I’ll describe and defend a reformulation of AP, which I’ll refer to as the <i>effective observation principle</i> (EOP). EOP describes what we can expect to observe in physical settings by considering our ‘observational situation’ (and not, specifically, ‘observers’)—understood solely in terms of effective theories.

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></div><div style='margin-top:12.0pt;margin-bottom:12.0pt;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;line-height:inherit;font-size-adjust:inherit;font-kerning:inherit;font-feature-settings:inherit'><p class=MsoNormal style='vertical-align:baseline'><b><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'> This talk will be available online through:</span></b><o:p></o:p></p></div><div style='margin-top:12.0pt;margin-bottom:12.0pt;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;line-height:inherit;font-size-adjust:inherit;font-kerning:inherit;font-feature-settings:inherit'><p class=MsoNormal style='vertical-align:baseline'><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'>Zoom: <a href="https://pitt.zoom.us/s/91855041780"><span style='border:none windowtext 1.0pt;padding:0in'>https://pitt.zoom.us/s/91855041780</span></a> and</span><o:p></o:p></p></div><div style='margin-top:12.0pt;margin-bottom:12.0pt;font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;line-height:inherit;font-size-adjust:inherit;font-kerning:inherit;font-feature-settings:inherit'><p class=MsoNormal style='vertical-align:baseline'><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'>YouTube at <a href="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><div><p class=MsoNormal style='vertical-align:baseline'><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'> </span><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>
