  • 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.




  • I dunno, I’m mixed on what the author is talking about here. On the one hand, it’s really not good to have any half of society just checking the fuck out; I think that the loneliness epidemic, regardless of gender, is a problem that is both real and addressable. On the other hand, what the author is pining for here is, imo, best left in the past. The kind of social norms she’s missing sound really unhealthy/toxic to me, and like they don’t really benefit anyone. I half expect some shit like this in Project 2025.
