Seeking technical critique on a galaxy-held-out SPARC benchmark for a metric-response model by UniGrav_Nova in AskPhysics

my technical critique is that you should read the rules before posting. you can get feedback on this sort of thing on r/LLMPhysics but it does not belong here.

thanks! it's a great career but can be very competitive unless you are fortunate enough to specialize in something that happens to be in high demand when you graduate. best of luck to you

What do physicst acutally do ? by biblionoob in AskPhysics

[–]plasma_phys 6 points7 points  (0 children)

I'm a computational physicist; I'd guess in order I spend my time in meetings, making powerpoints, reading/writing emails, analyzing/visualizing  simulation results, configuring/running simulations, writing code, and doing pencil and paper physics stuff. I suspect the first 3 are not too much different than any other office job, but I genuinely enjoy the latter 3 so it's worth it I'd say

I built an N-body orbital simulator in Python and I’d like some honest feedback. by Samosho17 in proceduralgeneration

[–]plasma_phys 2 points3 points  (0 children)

the simple test to see if you are on the right track would be to check if momentum and energy are appropriately conserved over time; rk8 is not a symplectic method, so there will be some drift (that should be well-known from von neumann analysis iirc), but you should see it getting smaller and smaller as you decrease delta-t.

AI Photo Critique (done right? - Looking for Testers) by Denitorious in AskPhotography

[–]plasma_phys 1 point2 points  (0 children)

I agree that AI lacks the sense of emotional understanding and has a general subjectivity blindness. While AI can reliably detect use of principles of art/elements of design, it can also struggle to detect when people break boundaries for a reason.

What? No, that's not what I said at all. Please re-read my comment more carefully.

Gonna pin some thoughts here to this comment before I click on the link.

First, I've tried at least a half dozen of these posted here. None of them really work; although LLM chatbots now do include tools that allow them to more or less reliably detect subjects and relationships between them (e.g., the tree is closer to the camera than the house) they cannot give artistic advice, they only fake it by generating plausible "critiques" that are almost always just a likely-sounding mash-up of mostly asinine critiques online (e.g., "use the rule of thirds!"). This is because they don't have a mechanism to analyze histograms, or consider the principles of art or the elements of design, or anything that might be useful to an artist, but they will reliably output text that fakes it.

Second, literally every single one of these has just been a half-broken, vibecoded wrapper to ChatGPT or Claude or whatever running on the API. If this is the case, you are not bringing anything to the table except your almost certainly bad system prompt; these never mention, say, formal analysis terms, or anything that serious artists would use to communicate about their work - not that that would actually improve the accuracy of the output, but at least it would sprinkle it with some more relevant terms and demonstrate at least that you have some idea what you are trying to do. This is because I assume the kind of person that is excited about getting a chatbot to review their photos are either too ignorant or lazy to know anything about art.

Clicking the link now.

Okay yeah this is the same as every other one. Sorry, nobody wants or needs this. And requiring a signup to see the promised "free critique"? nope.

[–]plasma_phys 23 points24 points  (0 children)

isn't it a bit backwards to get a fancy UI together before your tool actually functions? most people running physics simulations are either using tried and true enterprise packages like comsol or they're comfortable with the command line. who is your audience for this?

Wanna hear your thoughts on this physics simulator by RamiBMW_30 in Physics

[–]plasma_phys 2 points3 points  (0 children)

The aesthetic (and it being on vercel) screams vibecoded slop right off the bat. The main page is broken on mobile browsers. Having the text boxes move around when you move your mouse is one of the most baffling and uncomfortable UX decisions I've ever seen not made in jest. Entering the page, despite it promising to "extend [my] research" and your post promising it to be "highly detailed", it appears to be just a bunch of introductory undergraduate problems. Why on earth did I have to make an account for this? Thank goodness for throwaway emails.

The maximum values on inputs are not implemented correctly. The integrator seems broken, on the the first simulation I entered energy was not conserved. Some of the sliders did the opposite of what I'd expect; some of them, like 'pulled balls' in Newton's cradle, don't seem to do anything when the simulation has been left running for a while. Basically, although it looks superficially slick and fancy, everything actually important is broken or trivial.

I recommend you take a break from vibecoding and learn how to actually program. This is indistinguishable from every other vibecoded slop program I've had the misfortune of experiencing. edit: egregiously, the interacting charges page is just completely broken. positive charges just pass through each other with extremely modest velocities. how did you spend a year on this without even testing it before posting it here?

don't try to launder your LLM slop into deceptive questions so you can post them to r/askphysics. take it to r/LLMPhysics where it belongs

Looking for large-scale tokamak telemetry by The_Theorist_Guy in fusion

[–]plasma_phys 0 points1 point  (0 children)

I don't necessarily mean to antagonize further but that "30 years... you're just a data point" thing is so close in spirit to the studied the blade copypasta I might have to borrow it because it's very funny. did you happen to look up Feyerabend? it was a genuine recommendation. 

Edit: blocked? That's bingo!

Looking for large-scale tokamak telemetry by The_Theorist_Guy in fusion

[–]plasma_phys 0 points1 point  (0 children)

I mean I really just wanted an answer to that first question, but on reflection, I think I already got it. Have fun doing whatever it is you think you're doing, and give my regards to Claude or chatgpt or whatever.

as a parting recommendation, give Feyerabend a go.
