  • okay, report:

    • good lord, Antares and Vega are offensively bright once you adjust to the dark.

    • M4!! HOLY GUACAMOLE WOW! M4 by itself made being out tonight worth it!

    • M80: cool, felt cool to find it, but it looks like any of the other tighter globs and I didn’t want to mess with switching to one of my narrow AFOV higher power eyepieces on my manual dob. May revisit once I invest in a higher power eyepiece with a decent AFOV.

    • Epsilon Lyrae: hmm, am I maybe just not using enough mag? looks like a regular double star to me.

    • Took the telescope for a slew through Sagittarius, for a laugh, was not disappointed. Breathtaking amount of stars there.

    • Was all aboard the strugglebus making sense of Hercules’s constellation. Didn’t help that he was at the zenith, which made using the dob weird when looking for M13 and made looking at the constellation annoying after staring straight up like a turkey for minutes.

    • Took some time to re-acquaint myself with Draco, Cygnus, and Aquila.

    • Didn’t pick out any more DSOs, in part because I got annoyed with blowing out my night vision, even with the red light, on my charts.

    • I’ve been fairly serious about the hobby for about 9 months now, and it seems like I saw way more satellites out tonight than I did when I stopped back in May. Bruh, the little bastards were everywhere.






  • “He’s giving a message to criminals where our federal officers are,” Bondi said. “…we are looking at it, we are looking at him, and he better watch out, because that’s not a protected speech. That is threatening the lives of our law enforcement officers throughout this country.”’

    Actually, I believe it is protected speech. There are apps that let people know where speed traps are. You mean it’s not constitutionally protected to say to someone “hey, did you see the cop down on the corner?” Ridiculous. Of course, what she means to say is that the constitution doesn’t matter and laws are made up now, and they’re just going to do whatever the fuck they want. They’re just not quuuuuite ready to go through the trouble of literally setting the constitution on fire yet.





  • Non-linear equations have entered the chat.

    Chaos and non-linear dynamics were treated as a toy or curiosity for a pretty long time, probably in no small part due to the complexity involved. It’s almost certainly no accident that the first serious explorations of it after Poincare happen after the advent of computers.

    So, one place where non-linear dynamics ended up having applications was in medicine. As I recall it from James Gleick’s book Chaos, inspired by recent discussion of Chaotic behavior in non-linear systems, medical doctors came up with the idea of electrical defibrillation- a way to reset the heart to a ground state and silence chaotic activity in lethal dysrhythmias that prevented the heart from functioning correctly.

    Fractals also inspired some file compression algorithms, as I recall, and they also provide a useful means of estimating the perimeters of irregular shapes.

    Also, there’s always work being done on turbulence, especially in the field of nuclear fusion as plasma turbulence seems to have a non-trivial impact on how efficiently a reactor can fuse plasma.
