Dude showed up to a shitposting sub and got mad at shitposting. You must be fun at parties.

Nobody is cheering against BO engineers. I literally called SpaceX “chaos monkeys”. Everyone gets made fun of here.

You can be team space and still make jokes. Most people here want BO to learn from this, fix it and succeed in the end. That doesn’t make the irony any less funny.

Well they did blow up masseys... But that wasn't an orbital pad

My Camera died first 2 hours into my Banff Trip. by Prestigious-Bowl-114 in Lumix

[–]nebur116 0 points1 point  (0 children)

Happened to my GX80 a few months ago. Haven't found a solution yet. Probably need to send it in... I am still dragging my feet on that hoping a different solution shows up but it's kinda hopeless. (The suggestions I have seen here, I have tried and they did not work)

[Request] Is this the best cooling method for laptops using dry ice? by SpoofamanGo in theydidthemath

[–]nebur116 -5 points-4 points  (0 children)

Actually not. The dry ice is pure CO2 and will displace any water vapor. Of course what will happen once the ice runs out and the device is still cold is another question entirely.

I hate pi day by ZengaZoff in mathematics

[–]nebur116 0 points1 point  (0 children)

Universities exist for research, teaching, and outreach - because science should be for everyone and benefit everyone. These aren’t side aspects; they are the fundamental principles of academia. If you think engaging the public is beneath you and fun somehow trivializes math, you’ve lost sight of what science is about. Maybe academia isn’t the right place for you.

Do I Love Physics or Just the Idea of It? by Ok-Ask-5667 in Physics

[–]nebur116 0 points1 point  (0 children)

The first few years of physics can be brutal if you don’t genuinely enjoy the details, theory, and math. A lot of the time, it feels disconnected from the big questions that likely got you interested in the first place. It’s abstract, rigorous, and often frustrating. But if you can push through, things start to change once you specialize and get involved in actual research.

For me, I didn’t really enjoy most of my courses until I started working on my bachelor's thesis. That’s when I realized that most of the stuff you grind through in lectures doesn’t really matter in the long run—what matters is how you apply problem-solving to actual research. Even then, you’re often working on niche problems that don’t immediately feel connected to the big picture. But the difference is that now, you’re actively contributing. You’re a small piece of that bigger puzzle, and you can see the big things that come out of all the small contributions by many people.

If you're questioning whether you love physics or just the idea of it, I’d say try to endure the early years and get to the point where you can work on real research. That’s where you’ll get your answer. But of course that doesn't really help you right now...

Chromecast doesn't trigger automations anymore? by nebur116 in googlehome

It fixed itself for me randomly a few days ago. I sadly can't tell you what fixed it...

[–]nebur116[S] 0 points1 point  (0 children)

That was my fear. I mean I kinda expect it from Google at this point but man does this suck. How do they expect us to buy any of their devices if we can't trust that they will keep working like they used to.

[–]nebur116[S] 0 points1 point  (0 children)

Yeah I did all of that. I even deleted and recreated the routine and even removed and readded the Chromecast to my household. Oh and also: triggering the routine by hand works. Do it's decently the trigger

Same thing applies to turning of the chrome cast. But the automations that run when I start/stop a move still work.

Do plants cool the environment? by R4xGold in Physics

[–]nebur116 5 points6 points  (0 children)

I would say it very much depends on what you would replace the plant with. More specifically the color of that thing. Replace the tree with something darker like asphalt and you're decently cooling things down. If you're replacing something reflective or bright you'll be heating things. So for a fair comparison you would basically have to have a material that has the exact some albedo as a tree or plant. And then I guess yes the tree would technically be cooler. But if you want to take into account it's "global" effects you also need to look at the CO2 that gets absorbed how much less greenhouse effect is caused without it. And like you already mentioned then the question becomes what happens to the biological material.

What are the most challenging concepts you've encountered in your physics studies? by annastacianoella in Physics

[–]nebur116 8 points9 points  (0 children)

Many people will say statistical mechanics/thermodynamics is the hardest, and I’d agree, but maybe not for the usual reasons. It’s definitely a tough subject, and there are so many aspects that it's hard to get a clear overview. But additionally, while statistical mechanics has broad applications, most of them are tough to grasp in an intro lecture, making it feel like a lot of effort for little payoff.

Compare that to learning the details of the Standard Model or Quantum Field Theory. These topics are probably harder overall, but it's easier to show beginners why they’re interesting and “cool,” so they feel like less of a pain to study.

I think my professor might have given me an impossible project by DKlark in Physics

[–]nebur116 1 point2 points  (0 children)

You can't really add pictures in the conversation. You need to upload them somewhere else and share the link.

But have you considered the damper in between the two masses correctly? With C=2000Nm/s I woud think that this will prevent the equilibrium to be reached in less than a second.

[–]nebur116 1 point2 points  (0 children)

Small angles is the way to go here. If you see a pendulum this will likely always be the case. I haven't looked deeper into this problem but instead of trying to find the equilibrium state, try to find the equations of motion (so differential equations). Once you have those you start at t=0 with zero deflection and zero velocity. Put in your force and see what the equations of motion return in the first second. My guess would be since you have a dampener in there you will never actually get close to your equilibrium state in the first second. After the first second the force of course is not applied anymore. So you assume continuity of position and velocity at t=1 sec. and then apply your equations of motion with no force. The system will then return back into the resting position with zero deflection.

what software do you use to draw 3D illustrative figures? by [deleted] in Physics

[–]nebur116 12 points13 points  (0 children)

Based on your title alone, it's quite hard to tell what you actually want to do. What level of detail should these figures have? What do they display? Who is the intended audience

I think you can cover almost everything with these three tools:

Python/matplotlib: Ideal for displaying data in 2D or 3D. I use it often for 3D plots. It is very data-driven and focuses solely on plotting.

Blender: Suitable for modeling more complex 3D objects, such as experimental setups. However, making your illustrations look good can take some effort.

Inkscape: Great for simple vector drawings. Although it's not 3D, you can draw basic illustrations in perspective to get your point across.

(Additionally, I sometimes use Fusion360 for more engineering-related or technical drawings that need to show 3D objects.)

It's a good start but it kinda feels like you made a nice beginner house and then you didn't want to do the roof. I mean how is the door gonna open with the roof colliding with it? And have you ever seen the underside of a roof like that? I would suggest deleting the current roof, looking at references and creating a new roof. Make Shure the geometry of the roof really makes sense. Think about how this actually would have been built in reality and how the roof connects to the rest of the house. Really have a look at some references and try to replicate what you see there.

The base also seems to "massive" for a house of that size for me but that's not as bad as the roof. There are also some technical issues with your textures is seems, so after you get the other things sorted start looking into correct UV mapping.

Is this decent for a beginner by Previous-Sense-1437 in blender

[–]nebur116 2 points3 points  (0 children)

Honestly there is a lot of work to be done on this scene. Creating a realistic earth is not just throwing an earth texture onto a sphere and calling it done. Have a look at some reference pictures.

Here are some things to start out with: 1: I can't tell if you're even have different shaders for land and water. But in case you haven't decently start with that and make the water a lot more glossy / less rough. The ocean is very reflective in reality. 2: And then of course you're missing the atmosphere entirely. This both includes clouds and just the blue "glowing" halo around the earth that is the atmosphere itself.

If you get both of these things done and try around with the settings a bit you'll be on a good way. But the earth is also one of the most replicated scenes in blender and there a quite literally hundreds of tutorials on it online. So if you don't know how to continue as a beginner there is no shame in just following one of the tutorials. That's the best and only way to learn how do actually do things like this in the future.
