hello physicists and physics enthusiasts. what field are you in? anything interesting lately, or problems you're stuck on?

jim.jpg
#

i used to work in astroparticles. not in academia anymore but if i go back id like to aim for IceCube https://icecube.wisc.edu/

IceCube
wiscqruo
IceCube Neutrino Observatory

The IceCube Neutrino Observatory is an array of optical sensors located in Antarctic ice that detects the presence of subatomic particles called neutrinos. It is operated by an international group of scientists called the IceCube Collaboration.

#

for a pretty superficial reason: the south pole is cool

trim aurora
#

I've sunk a couple hours into looking at antarctic jobs and possibilities before

#

I ended up reading about pilots who fly small planes in northern Europe and Canada (can't really remember where)

#

It seems like those places can be similarly appealing with lesser effort required to get there (but are there any research jobs? I don't know)

#

To be on topic a little bit more, I'm an electrical engineer who's been roped into doing some quantum computing experiments so I desperately learn physics jumping between undergraduate and graduate resources while trying not to get too deep into the wrong thing

#

it's sort of hard to tell if I'm actually learning efficiently so I'd be curious if anyone else had any advice on how to do this well (kind of a vague question but maybe some interesting thoughts)

#

i briefly dipped into quantum stuff during my masters but i'm not sure what the best way to learn the material is

#

someone who i respected very much just did all the exercises in Principles of Quantum Mechanics by Shankar

#

but that's kinda fucked up

#

I think Sakurai's quantum book is somewhat well-aligned for people who want to do quantum computing

#

it feels a little more discrete than like Griffiths

#

I think I also read some of Quantum Computation and Quantum Information by Nielsen and I liked the presentation of the material but i didn't get that far before getting distracted

#

it's also the first result when you google "quantum computing textbooks" so it's not really an insider secret

graceful wing
#

also antarctica is also already kind of a substitute for space for me, hehe.

graceful wing
#

also, i have a signed copy of griffiths. i asked him to write "letter of recommendation" with his signature but he just laughed and wrote good luck with your work

trim aurora
# prime jewel someone who i respected very much just did all the exercises in Principles of Qu...

I'm mostly scared of devoting my self that heavily to one book because I don't know if it actually covers "everything" I need to know. There's a lot of stuff around QED for example that sounds like it's just insane and not covered in any beginner's textbooks like that from what I've seen. Possibly I'm just being too ambitious trying to find one text book that does everything though and I should be getting the basics down well.

graceful wing
#

oh damn QED huh? youd need like a particles/qft textbook for that

prime jewel
#

i just found that it wasn't a reference i returned to very often, probably because i was working on discrete quantum systems?

graceful wing
#

tru, i know very little about quantum computing

trim aurora
#

Possibly the main issue is I don't really know what I need to know, I think possibly you can ignore most of the QED in quantum computing and you just don't understand it as much but you can still make good enough predictions.

Right now I'm looking at superconducting circuits the analysis of which is based on "circuit QED" which is basically just QED on standard circuit elements like inductors and capacitors with superconductors as wires.

#

Circuit QED in itself is of course derived from QED stuff but I think if I just ignore those derivations I can understand things enough

#

Hard to say though

#

My approach right now is kind of just learn what I need to as I go and see what happens

graceful wing
#

thats kind of true even for physics proper like you dont really need to know QED very well to do experimental particles, but that seems unwise

trim aurora
#

I'm taking a quantum computing course right now and the prof said he doesn't know maths well he just knows how to use it as a tool

#

I think maybe I should do the same but using the physics as a tool for engineering things

#

It's good to know the depths of QED are rather esoteric

prime jewel
#

if superconducting shit is involved that's kinda scary

#

oh i know of one QED book that i kinda liked

#

but you have to look past the very unfortunate title

#

Quantum Field Theory for the Gifted Amateur by Tom Lancaster

graceful wing
trim aurora
#

Don't apologise for unfortunate titles, ever since I learned about this concept in electromagnetics (which I can't even say on discord without it getting deleted by the automod) I was prepared for anything

unknown.png
prime jewel
#

heh

trim aurora
#

and it's cousin which is maybe the most ridiculous named thing I've ever seen in physics

unknown.png
#

there's an entire r-word naming scheme

graceful wing
trim aurora
#

Well they did predict infinite energy being radiated from black bodies, if that was really happening there would be a catastrophe

indigo crag
#

I got an AA in physics and considered transferring as a physics major

#

i want to make physics puzzle games but ended up going into biology

#

I kinda want to do some biophysics research though

#

study electroreception in plants maybe :>

trim aurora
#

I wasn't into biology at all until I started thinking about how microorganisms work

graceful wing
indigo crag
trim aurora
#

I was reading it because I was interested in making a particle sim / cellular automata that could maybe mimic real life cells a bit

#

just ended up realizing that it was absurd

#

the fact that they just have funky motors in there is so crazy to me

indigo crag
#

mhm

#

also atp synthase has a wheel protein too iirc

trim aurora
#

and just how much we know about it too

#

I have no idea how this information was obtained

#

it's mind boggling

indigo crag
#

science documentaries need to go more in depth on how people figured out stuff by talking to science historians more

#

it's really interesting usually

trim aurora
#

I find you learn a whole lot when people explain the history as well

#

I only got that from a few physics profs

#

but it's very nice to build up an understanding of why we know things

#

instead of just taking it for granted

#

also gives you an idea of what kinds of experiments are doable etc

indigo crag
trim aurora
#

The other thing with biology that I think about is that it's possibly the pathway a next level of human design. Whether that means artificially creating something that can chemically replicate and form the structures we want in three dimensions instead of using lithography, or shrinking our data storage down to chemical sizes, or creating biological organisms that can self replicate and do our bidding

#

there's a lot of insane next level things possible there

#

"possible"

#

this is from an outsider who doesn't really know what the limits are

indigo crag
#

should help for materials design too to some extent

trim aurora
#

my perspective on this comes from the fact that a lot of the profs I talk to in the computer engineering field think transistors are almost done and we're desperately trying to replace them but no one really knows what to use yet

indigo crag
#

there's a guy that got yeast to make spider silk protein and wants to try to make a building material by combining it with chitosan which is modified arthropod shell or modified fungi cell wall polysaccharide

trim aurora
#

interesting

indigo crag
#

physics puzzle game I want to do involves rotating space stations

#

need to practice programming with GUI libraries or something

#

i kinda got the basics of it down in a text based system

#

but wanted to have a GUI

trim aurora
#

I'm potentially doing a gave dev thing at my university where we make games in 10 person groups over a year

#

It seems pretty interesting

#

maybe in 2 months I can give you advice lol

indigo crag
#

thank

trim aurora
#

I think in general for 3D stuff it's best to use an engine like unity or something like that, but you can also be wacky like minecraft and write the engine in a language that's good with graphics like Java

indigo crag
#

tried to do it in unity but gave up pretty quickly :/

trim aurora
#

I haven't touched it yet, I'm scared but I was hoping it's just hard at first then gets easier

indigo crag
#

all the game engines have gravity work a certain way by default

#

and the whole premise of my game involves it changing dynamically on a moment to moment basis sorta

trim aurora
#

damn I didn't know the engines would be that rigorous

indigo crag
#

so have to be able to program that part of it, i feel like it wouldn't be too bad if i just found the right tutorials

#

also would need to learn a bit of javascript and C++ if im gonna mess with unity scripts tho

trim aurora
#

as a total beginner it might make sense to ask in a forum whether unity is the right approach for your basic idea before going to deep into it

indigo crag
#

i might not have to mess with gravity directly and it would be easier if I didn't

#

theres a few different ways to do it

#

just have to pick a game engine when i have the time and make it work

trim aurora
#

what I've learned about learning roughly is if you have no idea what you're doing you should do it in 1-2 week projects and if something takes over a month you should just move on to the next thing

Once you're confident in all the skills required to make the big project you make something bigger that takes longer

vestal crane
#

It is like bacteria developed the wheel before humans

#

I feel like dying every time some one asks me if I watched bigbang theory, after I says I do physics.

graceful wing
#

watching tbbt as a teen made me want to do physics

vestal crane
#

I don't think that is shameful, discovery Channel made me do it

#

I wanted to be a cartoonist, I burned all my drawings and started to study math

#

And I get compulsive about things, so I went from drawing 12h a day to studying math 12h a day

hallow cargo
#

I'm really bad at math but one time i conceptualized relativity in my head when i was around in college and the "simulation" brought me to 3-torus-model theorems and I've been obsessed with dimensions and space sense; I think.

Also time is funny innit. Supposedly Spacetime but Quantum? How do we reconcile these fields?

vestal crane
#

Yeah a student of middle school could deduce especial relativity with the results from Michelson Morley experiment.

#

Don't know what 3 torus model theorems is

#

Not sure what you are talking, you say the unification of quantum mech and general relativity? I don't know

#

Generally people don't even see general relativity, it's optional. Physicists will really know quantum mechanics and eletrodynamics

#

And generally people only learn the Copenhagen interpretation of quantum mechanics

#

What book have you been reading about those fields lately? You are doing stuff as hobby or is it your field of study?

hallow cargo
#

Hobby, of course. I'm a dumbass with wikipedia and too many astronomy articles on my feed.

#

I'm holding a sword in my profile pic.

#

I'm kind of a caveman.

#

I have dyscalcula so i abstract what I can from conversation and data chart.

dire widget
#

Now that's a thread for me haha

#

I'm an astrophysicist, I specialize in numerical simulations of high energy (relativistic) flows

#

And these days I'm working on finding self-similar solutions to describe the interacting region between two layers with different properties that evolves as powers of time and distance. This is to facilitate simulations of a relativistic wind being launched in a supernova remnant

hallow cargo
#

Interesting. Universal Turblence?

dire widget
#

Nope, no turbulence in my models, for now I'm doing mainly 1D work
I try to keep up with the current research as relativistic turbulence is a viable particle acceleration mechanism (and it's those accelerated particles we see in our telescopes)

hallow cargo
#

Right. I was thinking if you can produce an accurate sim

#

Well, measuring the resistances of the explosion

#

If you can measure how strong the explosion is from light ie Heat

#

And compare that to the sim

#

Wouldnt the margin of error express basically the barometric pressure of the void

#

I know, it's not a fluid or a gas. And we can't time light very well yet.

#

But, heck, what you're doing sounds fun to speculate over at least.

dire widget
#

We simulate the outside medium not as vacuum but as a very-low density extorior though, and even though it's very low (talk about 1 atom per cube centimeter) it has an influence on the dynamics and emissions of those high-energy explosions

hallow cargo
#

Well that 1 atom sound useful for a mesh, right? Something trackable

#

But even that as you said has an influence

#

I guess there's only so much in our purview.

dire widget
#

Nah, you can't simulate per atom, it's far too costly

hallow cargo
#

Water, water everywhere.

#

Right.

dire widget
#

Plus the density of the supernova is like 10^10 times higher than this medium. We use the (relativistic) fluid equations for those objects

#

At least at those large scales

hallow cargo
#

I could probably never get into astronomy besides the math issues over how depressing it gets sometimes being one of the sciences where we don't even know how much we don't know.

#

It's not even the Dust Speck existence thing, it's more like, uh, waiting to wait. Knowing that some of the key stuff we have can't even be measured in an empirical sense.

#

But i still like geeking out over elementary stuff like accretion discs, and solar system formations, black holes, and quasars... it got scary again...

dire widget
#

"elementary stuff" lol

#

Those are very active fields of research

hello there, smart folk

#

magnetic tunnels enveloping our near system makes me think crazy sci-fi shit if not worse

unknown.png
dire widget
#

I know it sounds like some weird sci-fi shit but it's just some magnetic fields haha

jagged shell
#

the reporting on it I saw implied we were accelerating towards the center of the galaxy

#

long time ago I read it tho

dire widget
#

The same way the Earth is surrounded by a big magnetic field (weak but big in size), stars and galaxies also have scaled-up magnetic field

#

Well in physics, gravitationnal pull is an acceleration, it doesn't necessarily means our average distance to the center is decreasing

#

But it could be I mean, wouldn't be surprising

Charlet try to go to the annual congress of the society of Physics of Brazil, we could meet and go to bunch of parties and cool amazing places, if you have good things to show they will pay for everything for you.

jagged shell
#

come to brazil, we got brazillian physics

#

not but seriously our science is actually solid, i mean to look up on a logician newton da costa looks like hes making some noise in the shark waters

vestal crane
#

The university of são paulo and unesp has really good stuff dude, honestly.

jagged shell
vestal crane
#

Go looks at the statistics

#

Go get some information before you say things like that

#

The main problem right now is lack of funding because of 97% cut in science and technology. Things got terrible with the coup and bolsonaro

jagged shell
vestal crane

Still university of são paulo is at the top of the rankings

jagged shell
#

i love youre literally BRAZIL STRONK

#

i love you** its like brazil can go into space again

vestal crane
#

Then get out of there dude, come to the usa

#

Get a tourist visa and live here in the glory of this nation

#

Stope been a stray dog in there

dude stop now youre embarrasing me

vestal crane

Come to nyc the city that never sleeps and land of oportunity

#

You are ambarassing yourself, what do you know about your own country or here?

jagged shell
#

ive been to the usa when i was 8, 13 and 15 xd

#

ive travelled a bit

vestal crane
#

Great, so next time don't come back to Brazil and stay here

#

Stay where your heart is dude, and look at the statistics

#

University of sao paulo is pretty good worldwide

vestal crane
#

Here, apply to this and get out side of Brazil, do like me and see real life with your own eyes

aw fuck off i aint falling for no brain-suck scheme so corporate america can get richer (((also i am dumb

vestal crane
#

?

#

You aren't dumb, why do you say this?

#

I felt like that too when I was younger, don't put yourself down. Come and see things with your own eyes, if I am wrong you show me then.

#

In the end it isn't about been dumb or smart, just been persistent and not giving up. Eventually you will realize that by been persistent you got smarter than people that you considered smarter than you. You just need to keep on keeping on and ignore the traps. Nowadays I feel I am know more things then friends I considered much smarter than me, but chose to work for banks or financial funds, they got stuck doing stupid shit, and due to that they become stupid too. You are your work in the end.

That is too abstract. What do you love? Mechatronics?

jagged shell

...im a sucker, i dont think i actually love anything. i mean - as to destroy it under a microscope ? to know it that intimately ?

vestal crane

So you are in high-school right?

jagged shell
#

been there

vestal crane
#

Stop that shit, you are not a sucker or stupid. Maybe you are naive that is all, and everyone is some how

jagged shell
#

but tbh its nothing of the actual grunt work

#

we do that in the competitions, our uni's actually the only who has two competing teams lmao

vestal crane
#

Do you like what the people research at your university?

#

So you are doing those robots for soccer etc, right?

jagged shell
#

i actually do sumo robots

#

they have little katana blades underneath them

vestal crane
#

Ok, I guess the next big thing in robotics are systems to automatize drug discovery and production

jagged shell
#

no

#

make cheap robot kill

vestal crane
#

Did you had contact with machine learning etc?

jagged shell
#

yes

#

oh well, such is physics !

#

a truly hermetic system

vestal crane
#

Are you sure your university don't have that print program?

jagged shell
#

man its ufabc

#

its not some cheap uni

#

its the fucking lula university

#

the one with the big red dick

vestal crane
#

Yeah it's not old enough to have enough recognition, just that. But in a few years it may be really well ranked

jagged shell
#

and just lagging behind 1-3ths usp, etcetera

vestal crane
#

Isn't it like bellow 200?

#

There are good researchers there, I know people doing meaning full things in quantum dots etc that were there

#

I know the stuff you are feeling, I been there too.

#

Keep the struggle man, follow your heart regardless of anything. Find ways of doing a good project of cientific iniciation and publish something, try to get posgrad at some institution in the top 100

i make words go boom

vestal crane

There good scholarships at Germany

jagged shell

there are

#

my friends got one, travelled all around europe, seemed wonderful

vestal crane

now thats shes back im actually too worried to ask her how its been

vestal crane

It's absurd in every sense I look in here

They didn't paid me, fuck ir

jagged shell

no bro its actually wednesday look it up

vestal crane

#

how is the normal conditions not fucked up

vestal crane
#

There is no university cantina with affordable food. The University I am at is public and full of anarchocapitalists

#

There were room floded with water from the ceiling, rooms with actual lab equipment and experiments. Shit is falling to peices

There are no parties inside the university, almost no social activities

I guess next is at são paulo actually

vapid blade
#

I have to decide what class(es) to take and meet with my potential phd supervisor soon

#

I feel like every time I meet with someone in this situation I always get memed into taking the ridiculous pie in the sky project and they never get finished

How do i stay strong and say yes to the normal achievable thing

Numerical GR is a huge pain lmao

vapid blade
#

On the last such adventure I tried to replicate some analytic paper which said very, very little about their actual system in order to evolve it numerically

#

I…am not sure that paper holds up

#

It’s gotten to the point of writing to the authors and that hasn’t given me much confidence either.

#

They basically invented this weird mode expansion in one spacetime and then copy pasted it to a bunch of other systems

graceful wing

#

Hmm, sounds a bit sketchy, some underlying conditions of those modes generation may not hold up

graceful wing

you worked on ligo or smth before right

vapid blade

Yeah I’ve bounced around between projects a lot but pretty much all black holes

10 months of “dude what does this plot even mean” call the profs statistician friend “oh no” later…I think we have learned something

Yo, help me out, I need topology memes

And geometric group theory memes too

#

ok that sounds bad and like

Dude, don't take too many risks unless you don't give a fuck about your mental sanity and ending in a bank

vapid blade

I did do a low risk ez group project once, and then what happened was everyone stopped giving a fuck during covid except me and a postdoc in India

#

Me = senior undergrad at this pt, so there was a lot I just didn’t know how to do

Postdoc in India was mvp and should be first author if we ever get our shit together

vestal crane
#

Yeah... it's been always like that for me

vapid blade

But then he got a job and moved to Europe and now he’s too busy to do the thing too

So we all just kinda let it go

vestal crane

I am my own supervisor in the end

I got to learn everything by myself and some how I succeed

With achool and tabaco

vapid blade

It’s safer in a sense to rely on less people

vapid blade
vestal crane
#

They ask if something is possible o always say it is

And manage to do it some how

Been like that always, lost a bunch of friends and relationships due to getting obsessed with things and forgetting about real life

I am from são paulo

vapid blade

Tinder is wack

Full of incubi

Yeah, i just can't care anymore, I have become schrodinger without the academics abilities.

Is it schrodinger or Heisenberg who was havin threesomes

#

Or somebody else

I’m seeing another grad student in a different department

It is terrible actually

Although I am financially ruined

vapid blade
#

well you’re doing physics

#

Not a lot of money except in industry quantum computing

vestal crane
#

Yeah, I am rich of immaterial things

#

Hahah

vapid blade
#

I thought about doing that but I’m just not that good at complexity theory or the kind of experimental stuff I’d be doing

#

Later I got a bit suspicious of actually-useful quantum computing always being 10 years away

vestal crane
#

It always like that with everything

vapid blade
#

(Don’t wanna knock quantum simulation, it seems like those guys are doing great)

vestal crane
#

Fusion reactors

vapid blade

Well fusion energy is like that because it’s super under funded

Quantum computing is flush with cash

vestal crane

Is it? They built a bunch of those

My undergrad lost its fusion reactor

Haven't France just made one?

And China too?

#

Yeah, there is a Russian tokamak at the university of são paulo

vapid blade

It seems like there’s only so far you can go with tokamaks anyway

To really optimize the deign you need weird shapes

#

So what is y'all's favourite interpretation of QM? 🌚

dire widget
#

Basically QM can be formulated as classical dynamics in infinite dimensions (using the moments of the distributions)

#

I discovered this recently and it feels so much more satisfying than the usual interpretations that were hazardously found when the theory was still young

runic widget
#

From a quick skim that seems fairly interesting as it shows one more way to see the similarities between QM and Hamiltonian mechanics. However I didn't catch anything that went beyond an equivalent reformulation of standard quantum theory and so it appears they did not even attack the measurement problem with this. Am I missing something?

I think this is my favorite interpretation

https://en.wikipedia.org/wiki/Transactional_interpretation

Transactional interpretation

The transactional interpretation of quantum mechanics (TIQM) takes the wave function of the standard quantum formalism, and its complex conjugate, to be retarded (forward in time) and advanced (backward in time) waves that form a quantum interaction as a Wheeler–Feynman handshake or transaction. It was first proposed in 1986 by John G. Cramer, w...

#

I don't know, I took a quick look at that geometrical interpretation, how they explain the duality particles and wave with that? Feel things would be only waves in that dots. I feel this one TIQM is more fulfilling to my mind. What do you think?

Have you seen those liquid silicone tables that is a mechanical analogous of the double slit experiment?

vestal crane
#

Makes sense for me, it is like a simetric version of that cone of time

#

Why does it bother you?

#

Think that if the space is soo small you will have a interaction of the future with the past, those are particles the moment the wave function collapses

#

I think that is also coherent with that interpretation of bohn were particles are surfing a wave o probability, that interpretation has an mechanic analogue, the silicon pool waving. It's feels better then the other things I seen

What does it feels better for you? I am drunk right now so I don't feel like punching you in the face anymore

I am trying to make an imitation cuttlefish eye but don't know the index of refraction of the cuttlefish eye lens or the index of refraction of the resin I'm using

#

I figured out the shape and imitated that, though I'm worried I made it too big and am not sure it will print properly if it is the right size.

#

I intend to imitate the optical properties of the lens by having a near-spherical lens to hopefully increase the axial chromatic aberration, and having the weird w-shaped eyelid/pupil to hopefully polarize the light a little bit?

#

Should have tested index of refraction of the resin first thing ig

vestal crane
#

Dude I have no idea, that must be really complex to imitate. I don't know how to even start to think about this to be honest. I will try to think about it again tomorrow, and see if I can think about some guiding. Doesn't that fish has like those reflections like cat eyes? Have you try to see if someone already did something similar, that you could copy and improve?

I not sure I got it, your idea is to copy the structure and the relative diffraction index of the mediums?

indigo crag
# vestal crane I not sure I got it, your idea is to copy the structure and the relative diffrac...

ideally I would do that, but the goal is more demonstrating the chromatic aberration and the supposed polarizing effects of the eyelid, which would mean not having too high of an index of refraction, but having the index of refraction change more as wavelength changes.

There's a fun theory that in principle cephalopods should be able to differentiate between colors even with just one photoreceptor due to axial chromatic aberration of the lens combined with their ability to move their retina closer or further from their lens, unlike us, meaning they can take advantage of the different focal points for different colors of light, in a continuous manner. I want to make a working model of this sorta, still not sure exactly how I want to go about it :/

#

maybe could try projecting an image through it, and changing the distance of the screen?

#

though seems like the other out of focus colors might just mess up the image since they're all captured together? In any case, somehow they're able to camouflage by changing different colors.

indigo crag
#

The detection of polarized light happens in specially arranged cells in the retina it sounds like, but not sure whether or exactly how the odd eyelid/pupil shapes help with this

#

https://pubmed.ncbi.nlm.nih.gov/23474299/ seems scientists think it has more to do with being able to see better in uneven brightness between stuff above and below them.
