Yes exactly, in an anarchist society I wouldn’t stop doing control¹ theory, I would do even more control theory because I wouldn’t have to worry about publishing profitable results, because I’m autistic and for some reason, math makes me happy.
¹ Control of dynamical systems, e.g. steering the state of a differential equation, i.e. math, not authoritarian control 😁
Hey another anarchist engineer spotted in the wild!
And hey at least control theory tends to have practical applications. I keep wanting to write basically a whole dynamics and statics textbook but where the formulas are extended to non-Euclidean spaces. Not just to like hyperbolic and parabolic geometry but to even more exotic metric spaces that aren’t locally Euclidean or necessarily continuous.
Not much use for that kind of math whatsoever, but it’s fun
What part of control theory are you focused on?

Check out the book Mathematical Control Theory: Deterministic Finite-Dimensional Systems by Eduardo Sontag. A lot of his results take place in general metric spaces. Make sure to read the Appendix first, because this dude is absolutely next-level with the math. You’ll see.
You might also want to check out Infinite-Dimensional Systems Theory by Curtain and Zwart for an account of linear systems theory developed for separable Hilbert spaces. And for nonsmooth control, check out Nonsmooth Analysis And Control by Francis Clarke.
So you might need to blend a couple existing ideas together. Give it a shot!

Immediately, I think it would have uses in quantum computing (where the state space can be an infinite-dimensional Hilbert space) and fluid dynamics (which are governed by partial differential equations, which can be represented as abstract differential equations on suitable function spaces).

PM me for more details since I don’t wanna doxx myself, but my interest is in nonlinear high-dimensional dynamical systems.
I have a control theory question unrelated to this post. Can I ask you in DMs?
Yup!
I feel genuinely called out - I thought everyone likes poking holes in clogs and watching standing water drain out. Especially people who walk or cycle a lot and don’t like being splashed by cars
In this case, we’re not so much calling you out as calling you in
sounds like a game development opportunity in the same vein as powerwash simulator.
Same. Sometimes when I go for walks in the rain I bring one of those little gardening fork things and clear out the drains. I imagine I look wild wandering the streets with a garden implement but it’s very satisfying and rewarding, especially knowing sometimes that water floods peoples houses.
I spent an hour today unclogging a drain my rain gutter goes to instead of trimming the bamboo bullshit like I was supposed to. It was awesome when the water went down. The bamboo got cut but that was shitty. More holes please.
Man I love going for hikes in the winter where there’s always a trickle of water along the trail, just asking for someone to scour a path off the trail with a boot or stick. Or a well placed handful of mud and gravel diverts the water
ngl I’d proudly photograph the standing water for a few different angles and the thought of unclogging it would never cross my mind
Would love to split my time between physics research and hobby botany/native plant restoration efforts. Would happily do both for free if I could. Damn capitalism
Right
honestly that’s me and my hommies at the ses https://en.wikipedia.org/wiki/State_Emergency_Service
we got a cool truck, loads of rad tools… and ocd.
you got a leak? tree fall over? ☎132500
free time is a bit lacking for me though :(
That’s so cool
There are entire youtube channels about unclogging culverts and storm drains. It’s genuinely a thing someone would just do, because people just do it.
my brain is broken to just absorb useless information… is there an opening for that?
Ever thought of librarianship?
