    It’s a movie about physics, with characters like Niels Bohr featured prominently, which just so happened to be made for general audiences and it was a hit, by a director whose other historical film was about Dunkirk.

    Before these movies were made, the subjects were pretty much obscure to the mainstream. Films like these are regarded as risky for large studios, and it’s widely acknowledged that Christopher Nolan is on the very short list of directors with the blessing to do absolutely whatever they want at large studio scale and budget and that is not part of a franchise. And by “very short list” I mean people like Stanley Kubrick.

    The “mainstream” label on Oppenheimer is incidental, after the fact.

    The analemma.
    Then since that 8-figure is diagonal, the earliest sunset and latest sunrise are about two weeks on either side of the shortest day of the year. Same in summer with the latest sunset and earliest sunrise being a couple of weeks on either side of the longest day.






  • Living in Baja, I’m at least thankful for not having mormon craziness right next door.

    Imagine northern Baja during Prohibition in the United States, jam-packed with bars catering to gringos looking to get plastered. That’s how Tijuana grew from a sleepy town to city virtually overnight back then. Many people still see Tijuana as a drinking-spree place, in reputation. Now imagine it was still that way, at that 1920s level of intensity.

    Imagine polygamy as part of daily religion and politics in the area. With so much territory equaling political agency, Deseret might have openly maintained their backwater, backwards attitudes towards women to this day. It would have seeped into Mexico. It would be part of the conversation.

    As it stands, we are buffered from those crazy mormon bastards by a series of layers with other types of crazy, and currently Baja could not have had better luck than with a neighbor like blue, progressive California.
    Thank god we don’t have Texas or Arizona next door. Sorry about that, Sonora, Chihuahua, Coahuila, Tamaulipas. We got lucky there in Baja.

    Dimensionless numbers, not dependent on any mere mortal, subjective arbitrary unit of measurement like length (meters or yards or cubits - same difference) or time.
    Whether you are on Earth or a planet in Andromeda or a billion light-years away, if you study subatomic structure you WILL bump into the fraction 1/137. Just like you will in geometry with 3.1416.

    A bullet fired from a gun goes more or less at Mach 1, correct?
    It’s thirteen years to the sun at the speed of a bullet?

    Spacecraft towards Mercury, or the Parker Solar Probe go much faster than that, take a few years to make it there, but they are doing so picking up speed in flybys of first Earth, then Venus, then Mercury, in several, ever tighter orbits.

    It’s both fun and illuminating to try and visualize these things in new ways. In this case, from the viewpoint of a bullet.
