>I haven't held a Reclam book in my hands for years! I might get it some time, thank you.
Sure thing. I don't even remember how I found that book, but I liked it...

>think of a total derivative as a Jacobian without a coordinate system specified
Ah, so the total derivative is a more general form of the Jacobian. I see.

>unless I am misreading, that is exactly true, since EL must be satisfied for all coordinates at once
Proof by prayer and confidence wins again

>I could give you a highschool-level derivation of Euler Lagrange I could write up off the cuff if you wanted
Thank u... I don't think that'll be necessary. I don't care about STEMtism right now. I've been feeling so lost again lately. It just all feels so silly & pointless & nothing is fun idk

>I'm sorry you have to deal with so much bs however, I wish I knew how to help you to those wonderful experiences I made
That's nice of you to say. I feel like it's not really a "putting up with BS" problem, more of a "me" problem. I am just incompatible with this world and most people. Things are fairly good right now in my life, I just feel so over everything

>even crossing Bundesland borders?
Prospected a couple of times outside of my Bundesland, was enrolled even. But it never worked out. Being an alumni at every uni in Germany is hyperbole of course but I've been enrolled at... wow, at least seven universities so far... it'll be eight soon... and I still don't have a bachelor's lmao. that's probably not good...
