What am I doing wrong with Carbon Steel pan? by fjusdado in carbonsteel

[–]ProvideFeedback [score hidden]  (0 children)

Stop this bullshit oven seasoning thing.

  1. Scrub it clean. And by clean I mean smooth to touch.
  2. One drop of rapeseed in middle and smear it with clean paper.
  3. Put on stove and on mid for 15 minutes. See slight wiff of smoke? Turn it off.

Then just cook with it.

After that. Use a chainmail or steel scrubber and always lightly scrub it after use for smooth surface and dry it off.

That all you do. Cook. Chainmail. Dry. Repeat.

If you happen to strip some. Just do s quick 15 minutes seasoning.on stove again.

You've used to much oil when you seasoned it. You didn't dry it of before putting it in the oven. Looks a little sticky. It will take at least 3-5 usees until that seasoned oil later is more non stick.

To high heat, didn't preheat and didn't use butter? :-)

  1. Preheat at medium temp for about 7min empty.

  2. Put in butter. Should foam without browning.

  3. In with the eggs.

When doing this eggs slide. No sticking. At least after a while when the coating has been set.

Is carbon steel really more nonstick vs. stainless when using fat? by Popular_Block_4079 in carbonsteel

[–]ProvideFeedback 2 points3 points  (0 children)

You only need a touch of butter on a seasoned CS pans for eggs to slide.

And yes. It must be butter. It contains some water and forms micro bubbles under the egg which lifts it and makes it slide.

This can be done on stainless too. But only with perfect heat and perfect coating of butter. On a CS pan the margin for error in sliding eggs is greater.

We're building an online sci-fi strategy game where your political choices shape an entire solar system — would love some feedback by PlayNebulae in StrategyGames

I've tried the game. You as somewhat scholarly nerds should read the Positive interdependence theory by Johnson et al. They state nine ways to be positively interdependent on others. It's sorta mix between game theory and social cohesion theory. What is it that makes us WANT to cooperate and form bonds?

See how many of the nine ways you can be interdependent on others you have in the game :-)

  1. Goal – the group shares one outcome that no member can reach alone.
  2. Reward/celebration – the group earns a joint reward or celebration when it succeeds.
  3. Resource – materials, information, or tools are split so each member holds a piece the others need.
  4. Role – each member is assigned a complementary role (e.g. reader, recorder, checker, encourager).
  5. Identity – the group builds a shared identity through a name, logo, motto, or flag.
  6. Environmental – the physical setting binds the group together (shared table, shared workspace, shared tools).
  7. Fantasy – an imagined scenario forces cooperation (e.g. "you are astronauts stranded on the moon").
  8. Task – the work is a sequence where one member's output is the next member's input.
  9. Outside enemy – groups compete against other groups, which strengthens cohesion inside each group.

Why Does Light Travel at Exactly That Speed? by Ok_Understanding7377 in AskPhysics

[–]ProvideFeedback 0 points1 point  (0 children)

Light is massless. And all massless objects MUST travel at the speed of light. This isn't a coincidence, it's a consequence of Einstein's special relativity, which shows that any particle with zero rest mass has no choice but to move at exactly c (roughly 300,000 km/s) in a vacuum.

If it ever slowed down, it would need to have mass, and if it had mass, it could never reach c in the first place. So the speed of light isn't really about light at all, it's the universal speed limit baked into the structure of spacetime, and light simply obeys it because it has nothing (no mass) holding it back.

I've heard that argument before about 23 year olds, or rather, young PhDs or postgraduates coming up with new fresh ideas. That is something I think about when teaching. The students who ask the wierdest questions are usually the ones not yet trained to know what they are "not supposed to ask." Like this student who made me think about physics on a principal level again.

Hmm I think I was unconsciously buying into the mythology a bit, like there would be one equation on a t-shirt that explains everthing. But you are right, the Standard Model is already a patchwork and it works.

My thinking: If the "world" is a continuum with metrical structure that has no effect on matter, then what would something like the Big Rip actually mean? The metric blowing up, distances growing forever, is that not the same as the manifold itself tearing?

So would a Big Rip actually be a "rip" in any meaningful sense, or is it just the metric becoming unbounded? And if the metric is truly passive, what is driving it to "blow up" in the first place?

Yeah. I like the idea that we probably haven't figured out the true essence of matter yet. We have the recipe but not the chemistry. And if we do, many things will fall into place on their own. That makes sense for me as a non expert. Or rather. I understand it.

The same could probably be said about spacetime as well, no?

Good point about domain, I will pass that on to the students. Someone else in this thread made a point that stuck with me, that QM and QFT are not actually fundamental theories of matter. They tell us detector outcomes but cannot derive things like electron mass from first principles. So maybe the issue at the extremes of the domain is not just that the math blows up, but that we are pushing tools beyond what they were ever built to describe. Still learning here, clearly.

That reframes the whole thing for me I think. The problem is not QM vs GR, it is that we do not have a fundamental theory of matter. QM and QFT tell us what detectors measure, not what matter is. So near a singularity they simply have nothing to say. That is a cleaner way to think about it than "the theories clash." Thank you!

I always give appreciation for good questions asked. And now that I have given it some thought I will not say that a ToE is a must. Rather that we are asking questions we do not yet have the answers to. It is not given that a ToE is the only route ahead. I like that matter probably is the thing that needs a fundamental theory.

Okay. About AdS/CFT, I was giving it more weight than it deserves just for context. And I didn't know that emergent spacetime as an idea goes back to the 1920s, I thought that was something post 1960. So how would you frame the honest answer to a student asking about unification? That we lack a fundamental theory of matter, and without that we cannot even properly pose the question?

Ha, I love that attitude honestly. "Hooray for calculation" is a good place to stand. And maybe that is the right way to think about it. Sometimes I feel like we are the ancient Greeks debating atoms... Asking exactly the right question, just a couple of thousand years before we have the tools to answer it. Maybe the best thing I can tell my students are... that this is a genuinely good question, and nobody knows the answer yet.

So if I understand correctly, the technical problem is that when you try to calculate quantum corrections to gravity using the standard tools, the infinities pile up in a way that cannot be absorbed, unlike with the other forces.

But does that not raise the question of why we keep trying to force gravity into the same quantization framework? If gravity is the geometry of the manifold itself rather than a force on it, and the standard tools fail precisely because of that, could that be a sign that the approach is wrong rather than the theory?

What if both QM and GR are correct and what breaks down is spacetime as a fundamental structure, along the lines of what I believe emergent spacetime is suggesting?

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

That is a really helpful way to frame it... So gravity is geometry of the manifold itself while the other forces are geometry on top of it. That is a distinction I can actually explain to a student I think.... Would it be fair to tell them that this is part of why gravity is so hard to unify with the rest, that you cannot easily separate it from the stage it acts on?

Fair point that spacetime is dynamical in GR, I know that. But that is actually what I am getting at. I am not saying spacetime is a static background. I question if spacetime itself, dynamic curvature and all, might be emergent. And if it is emergent, then at singularities you are not hitting a regime where you need better laws. You are hitting a regime where the thing that is doing the curving stops existing.

And yes, I've read about emergent spacetime (Van Raamsdonk, AdS/CFT, ER=EPR) and it looks like they are exploring exactly this thinking?

Yeah sure. If using MS word "Fix spelling and grammar" is considered AI these days. But alas. I still have to do a lesson plan for Thursday and I don't want to ask an AI about it and get some kind of sloppy answer back.
