I did this a while back, having read probably all of the Jordan ones from 5 on pretty much when they came out. On the one hand, relative to their size you can read through them pretty fast. But the Sanderson books are pretty meh and not really worth doing a reread of the whole series for. Books 2-4 remain the high point, I would say

Addendum: having now had the chance to start on Silksong, strongly recommend Hollow Knight first. That's not because of story, but because Silksong seems like it's geared to be noticeably more difficult than Hollow Knight was, both in platforming and in combat. (One of the things that I think Hollow Knight did really well was the spread of available difficulties. Beating the game isn't too hard; getting the true ending involves a few more specific difficult tests; and the DLC added boss gauntlets that let you go pretty crazy with how hard you want to make it.)

I mostly agree, and would say you should just play it blind. If you care about getting 100% (112% after the DLC) there are probably a couple of things where looking them up would be useful. It is also a very big world, so trying to do cleanup once you have all exploration tools can be quite involved

It is very much worth playing but you could probably skip it. As others have alluded to, the storytelling is very influenced by Fromsoft (Souls games, basically) and is pretty oblique. But, even without following it exactly, the gameplay itself is still great, and the music and art do an excellent job setting up a melancholy vibe. The different zones have a lot of personality.

I would assume that's mostly a function of this being for a general audience. Yes, you absolutely can talk about quasiparticles using techniques adapted from QFT. I don't know if Landau originally conceived of it that way, but there were definitely a bunch of Soviet physicists shortly after him who did.

In the article, "quiet" and "comfort" are bolded in that section, indicating that they are referring to Bose QuietComfort headphones

Hadean Lands is also very cool

Yeah, I would not point somebody unfamiliar with Stern-Gerlach trying to learn "the basic idea of quantum mechanics" at Sakurai. Feynman lectures vol. 3 maybe

Well, the characters are stuck on a primitive planet in the Slow Zone so if you go in expecting Space Opera then you’ll be disappointed.

Except half of Fire Upon the Deep was characters on the same planet but it was actually cool. The first two books are definitely among my favorite sci-fi of all time, the third one was a dud.

My main gripe is that these three books all share the same trope that underpins one of the major subplots: glib, charming politician type is scheming, eeeeevil. In the first two books, there's enough novelty (how the Tines and Spiders work, programming as archaeology, localizer mania) to make up for that. But I don't really think the third book adds much in the same way, and it is also very clearly building to a confrontation that will happen in a future book. So the staleness is much more noticeable

I spent quite a bit of time at the end of high school into early college playing on a Forgotten Realms themed MUD. It accomplished two valuable things: it durably increased my typing speed by 20-30 wpm, and it also inoculated me against the MMOs which would have been way more destructive for me.

You might be interested in Kip Thorne (of Gravitation fame) and Roger Blandford's book Modern Classical Physics, which is designed to cover the elements of non-quantum physics that are generally ignored in the first year PhD curriculum. Part headers: statistical physics; optics; elasticity; fluid dynamics; plasma physics; general relativity

I largely agree with your comments in this thread -- I'd been thinking about trying to express the same thing myself. I'd been guessing the motivation would be ML, where I feel that most people substantially overestimate how much they'd need.

Signals processing, though, is one of the places where I actually think a decent understanding of some of the higher-level concepts in linear algebra is really helpful. Linearity itself comes to mind, and maybe it just reflects my physicist's education, but it's hard for me to imagine having a working understanding of Fourier transforms without getting the idea of changing bases. I feel like you're about halfway through a first linear algebra course before you'd get there.

EDIT: that said, a good signals processing book probably covers a lot of this in sufficient depth if you can figure it out. The other catch-all comment I'd make is that linear algebra from a math class can look somewhat different from practical linear algebra on a computer. (That it's often a bad idea to directly invert a matrix for many computing applications is non-obvious from math class.) A book like Trefethen and Bau is great on that latter subject but is not a good starting point for OP.

When the conductor is grounded, the charge on the conductor is no longer constant. It can change until the total enclosed charge in any sphere surrounding the conductor is zero.

Nocedal and Wright is good. +1 also to the suggestions for Boyd and Vandenberghe. I really like Boyd's writing in general; he has coauthored some good review articles on proximal algorithms and ADMM.

A couple of other suggestions:

Nesterov's Introductory Lectures on Convex Optimization. This one is pretty tough sledding, but I found the perspectives in the first chapter particularly to be enlightening. It seems like there's a newer Springer book which is probably an expansion on this.

Bertsekas's Nonlinear Programming. Bertsekas has written a lot of books, and there's a fair amount of overlapping going on. This one seemed to be the one that has the most nuts and bolts about the basics of optimization.

EDIT: If you want more understanding of convexity beyond what's presented in these books, Rockafellar's Convex Analysis is helpful.
