      OK I’m now going to look into the scientific background. Turns out this was the FIRST optical pulsar observation, and it was a big deal

      > because it was extremely unclear how pulsars could work, and the hope was optical observation would constrain that. Was a race to find one

      The science is actually extremely cool: https://en.wikipedia.org/wiki/Crab_Pulsar … This is the neutron star remnant of the 1054 supernova!

      Here is the post hoc version of the discovery: interviews for pop-science audience. https://history.aip.org/history/exhibits/mod/pulsar/pulsar1/01.html … [ten web pages]

      I got completely derailed by this! Didn't know the story of the optical discovery, was cool to read about the tinfoil hack and 2*pi errors

      Yeah, that’s really great. Fascinating both for its own sake and as nice examples of how science actually gets done: improvisationally!

      This skillful technical situated improvisation is a key aspect of “shop work,” which is critical & most theories of science overlookpic.twitter.com/e5FfNL01Kn

      BTW Philip Morrison (Cocke’s PhD supervisor) taught my intro MIT physics course. It was first thing in the morning and I learned nothing :(

      This is trying to say: *to count* as science, C&G have to turn their messy improvised activity into a rational post hoc account.pic.twitter.com/K7MxCKGeEA

      This is what “accountability” (a key ethno jargon term) means: retrospective rationalization according to social norms. (cc: @Jayarava )

      The relevant social norms in this case are the highly technical standards for publishability as observational astronomy
