So my tentative reading is the hidden central theme is objects and perception/measurement, which is what phil of science got stuck&failed on

Logical positivism, which was the last philosophically serious rational account of science, assumed objects were objectively separable >

and had objective distinct properties; but this is actually incompatible with fundamental physics, and so failed. Cfhttps://meaningness.com/boundaries-objects-connections …

There’s a slew of neutrons out in the Crab Nebula, and a slew of photons coming our way, but there’s no objective criterion for “pulsar,” >

They’ve used all this equipment and theory to carve away the pulsar from the rest of the universe. Which we all do every sec with other objs

This case study has 2 cool features: (1) unfamiliarity makes it easier to see the active work of object & category imposition

which otherwise we pass over without noticing it because it is so familiar and automatic and unproblematic

Seeing a jam jar *as* a jam jar is nearly instantaneous but seeing the star *as* a pulsar took all night and went through multiple stages
