I mainly use note taking apps for fiction writing and up until this point I mainly used Notion. I want to switch to Obsidian because I've been trying to avoid cloud only services lately, but I'm finding the general layout of Obsidian too obtuse for my liking. In Notion I could write on a general topic and place subpages related to them but Obsidian is limited to either files or lists. I tried linking pages together but so far that just made things messier.

I know Obsidian is very customizable but it's so much to learn all at once that I don't know where to start making it work for me.

I was on TV Tropes (I know, not the best idea) and from scrolling came across their page on the subject.

Magic vs Science is a trope I generally dislike because authors of it never understand what science actually is. They treat it as building advanced technology rather than a method of understanding, and in settings that aren't earth the line between the 2 is arbitrary and contrived.

On the page however it listed different forms this conflict can take, one of which was the 2 being an ideological split rather than 2 separate parts of the world. That got me really intrigued because science as mentioned earlier is more accurately described as an ideology and a method we use to test and under

I've heard that conservation laws stem from symmetries per Noether's theorem, with conservation of energy coming from time symmetry, linear momentum from linear symmetry and rotation momentum from rotational symmetry. Energy is not conserved on long time scales because the universe isn't symmetric in time.

That part makes sense to me but it got me thinking, is it possible to describe a hypothetical space without linear and/or rotational symmetry as well so that neither form of momentum is conserved? And if it is possible to describe one what would it look like being in it?

It can be from any medium.

What I mean is, do you guys happen to have any worlds or world or anything for that matter that's inspired by something? Like something that makes someone think

"Yeah, this guy definitely likes some things"

I have a world inspired by stuff I like. It has a lot of stuff happening in it that I also like. I'm posting this because I'm tired of seeing worlds I don't like.

I'm curious to know if anyone else has done something like this?

I got an offer to do a masters program here that I'm excited to do, but I'm a little self conscious about my age. I'm a few years older than most people would be when doing masters and I'm worried I'm not going to be able to make friends and build proper social circles and relationships. Is this seen as a big deal in Uppsala or if it more likely most people won't care?

I've heard it said that electromagnetism and the nuclear forces can be described via curvature in a similar way that GR describes gravity, but instead of being a literal curvature in spacetime it's a more abstract curvature in the gauge field of the force.

I know the Higg's mechanism isn't a fundamental force but that still got me thinking, is it possible even in an abstract way to describe it using curvature as well? And if it is, would it be a curve in the Higg's field or in something else?

I recently got an offer of acceptance for an astrophysics masters program. Astrophysics is what I'm passionate about but I know the odds of getting a position in the field are low and odds are I'll have to get an industry job. Because of that I also applied to a masters in applied physics at a different university. While I'm more interested in astrophysics as a program and I'm worried in the long term it might not be the best choice.

The issue is the university I applied to with the applied physics program has a different schedule for offering acceptances (this is in Europe) and I might not even know if I get an offer from it until after the deadline to accept my offer from the astrophysics

Early on physics is just rearranging equations and plugging in numbers, plugging and chugging as they say. Then during the actual degree the problems become more about deriving equations and proving results.

My issue is even after completing such courses I feel like I never truly stopped. Even as the questions got more complicated my understanding would ultimately boil down to just knowing the steps, and when presented with a problem they didn't work for I was clueless what to do.

I feel like I never truly learned the problem solving needed for physics and have been unsure if I can handle continuing further in it. If you also struggled to break out of this pattern what ultimately worked fo

This is very hypothetical so bear with me.

People say that if time travel were possible using any of the proposed loop holes for it that physics itself would cease to have any meaning, because to describe a system mathematically you need to have initial conditions to model how those conditions change over time, and without cause and effect the outputs can effect the inputs. Thus most people say it can't be possible on that basis.

I'm not trying to make a case for time travel, my question is in the hypothetical scenario that it was actually possible, would we still be able to assume causality holds at least locally? Conservation of energy for instance isn't true universally as the universe
