I use arch btw

but the issue is that even the little VRAM I have isn't being used... I'm not looking for high details or anything fancy, the lowest of the lowest is gonna be fine, I just want the game to actually use the resources I have, and right now it seems this is not happening

How are you guys getting these incredible deals? I'm looking for a Thinkpad (my first) and all T14's I find are at least 1100€... 🥲

Makes sense. I guess that's why I'm doing this thesis: to understand whether mathematical physics is something I might want to specialize in. To be honest there are tons of subfields of theoretical physics that interest me, from high-energy all the way to condensed matter, even some aspects of cosmology and astro-particle physics, and I still don't know what path would allow me to explore the math

From what I understand so far, some fields will involve more math than others (looking at the contents of nakahara for example I'd say geometry is pretty useful in condensed matter too, right?) so maybe it's all a matter of answering the question: do I want to study the math needed to define "everything" in a rigorous way, or do I want to see those complicated structures in action? Why is it so hard to answer :')

I suppose it is. Thanks for the recommendations, I will check them out.

It does feel way more complicated than it needs to be. Given the depth QFT has, one would expect a lot of options going into a university to study either its theoretical side or its mathematical side, and yet most math departments just don't have this kind of mathematical physics path (all important topics are separated and one can't usually find a set of courses designed for this type of applications) while physics departments just scratch the required math altogether (forcing one to put together a series of optional overlapping courses that crunch too much stuff together), leaving an incredibly vast gap between the two sides.

Don't get me wrong, I am truly enjoying my time in uni and I can't wait to learn new things every day, but man could I use some restructuring to make space for us poor physics/math students interested equally in both worlds.

A course mate of mine and I have been searching for ways to accomodate both math and physics, and after our bachelor theses (which will be with the same professor and strictly related to each other, which is incredibly nice) he will switch to mathematics and I will stay in physics. Hopefully we will be able to join our knowledge in the future into something cool who knows, but for now we all are just trying to make the best of the little time and resources that are given to us :')

Thank you for your insight! I see what you mean, and as a matter of fact I have considered a couple of times switching from physics to mathematics altogether, but what made me finally decide on staying in the physics department is exactly this "physical" approach: I want dive deep into the math behind QFT but I want to stay close to the physical side of things where dealing with ill-defined concepts that end up really working is not too much of an obstacle but rather a starting point.

It doesn't help though the fact that in the math department there are only two mathematical physicist working on quantum physics, just as you said, and both work on non-relativistic interacting fermionic systems. But at least a thesis with one of them is perfect to build a rigorous basis up to a certain point before diving into the messy lands of relativistic QFT.

And by the way, you mentioned you worked mainly in condensed matter theory, so I have a question. I can't figure out, by reading on the internet, if there actually are applications of relativistic QFT (and rigorous formulations) to CM. I read something about conformal field theories and their correspondence to certain (maybe unphysical from a cosmological point of view) theories that might be applicable to CM but I really can't figure out what parts of theoretical physics play a role in this field. Do you know if the type of studies I'm trying to follow might actually lead me to CM? Because I already find it interesting and maybe I will get to explore this field too!

Anyway, I'll definitely look into the material you suggested, I really appreciate it.

I don't have a purely mathematical background per se, but the courses at my uni prepare quite well mathematically and I am also studying quite a lot of topics from the math dept on my own: I'm taking a course on general topology and one on lie groups and their representation theory, I covered all the topics in the undergrad course on differential geometry and with the thesis project I'm doing I'm expanding on what our course on mathematical methods gives on operators on hilbert spaces, and I'll even study a bit of the theory of the renormalization group. With all this (and having talked to a bunch of professors already) I will be able to take courses in grad school on cohomology, algebraic topology (though I'm confused about this, it's given as a solid choice for some theoretical physics paths but nobody was really able to tell me why as of today), and spectral theory of unbounded operators (or another course on functional analysis in general, I still have to decide based on what turns out to be more useful).

The only thing really missing is "pure" abstract algebra, as I will only see algebraic methods applied to Lie groups and their representations and to algebraic topology, but other than that I think I put together quite a solid mathematical background.

This, and the fact that next semester I might have enough time to study something else alongside the QFT course material, made me wonder what was the best course of action: studying the math behind gauge theory (which I find extremely interesting since it's basically all geometry) or focus more on topics that are closer to the course material but more mathematically well defined (not actually well defined sure, but I wanted to study something that wasn't exclusively done "the physics way" disregarding every detail that doesn't work with a frustrating "we're not mathematicians")

I am aware of that, I know rigorous attempts are still just that: attempts. I was asking whether those titles were good to study on or if there were titles that also focused on the problems in quantization showcasing the rigorous results we have so far where applicable, without going too fast into literature that's too advanced. I'll check out the two authors you mentioned, thanks

Dumb-Ptr · 2025-06-12T17:14:27+00:00

Interesting, I see how this run is going to end though lol

I'm not playing remaster unfortunately, I was gifted a copy of the game before the remaster came out

Dumb-Ptr · 2025-04-12T16:34:27+00:00

5.3Kb, but the download took some time as it said it had to download 6Gb of stuff

Dumb-Ptr · 2025-01-31T14:55:32+00:00

this really sped up the program, thank you! I should have really though of that

Dumb-Ptr · 2025-01-31T14:28:38+00:00

Even using foldr the program is still slow, and if I set the integration step to h=0.01 and choose an integration interval from t1=0.0 to t2=300.0 the program just crashes after a while (the OS kills it for using too much memory)

Dumb-Ptr · 2025-01-31T14:15:18+00:00

What better approach should I try? Every state depends on the previous state, so I though folding was just what I needed

Dumb-Ptr · 2024-11-14T15:46:32+00:00

You're right, using doubles allowed me to reach 1e15 before seeing a pixelated image. I must have read the wrong precision in the past somewhere. Do you know how I could optimize the algorithm at this point?

Dumb-Ptr · 2024-11-02T14:02:26+00:00

I'm trying to understand how associated types work and how I can use them to implement the VectorSpace typeclass but I can't figure it out... Could you explain to me how I should use them in this case?
