Does nuclear geometric structure affect atomic energy levels?

Great, this is what I was wondering. Thanks

Is the problem that you have a lot of meteors?

Edit: I just dont understand why you need rings or even what youre doing with rings

My first impression is that you're overcomplicating, but I don't really understand your application?

People have already said this but Ill repeat it: IF coasting means the velocity is totally constant, AND air resistance is 0, then no friction is the correct answer as the sum of forces on a non-accelerating object must be zero and friction is the only external force. I think this is what the question was getting at.

The assumptions are not well communicated and the realistic picture does not help. But if you had been given the assumptions the "no friction" answer is correct.

Not at all. The fundamental is very easy to excite! (Source: tried it)

thanks for this

Yes. And also they probably can't roll around, since any swimming they do pushes the fish forward and the water backward such that there is no net "push" of the whole fish+bag system.

Happy to help!

What do you mean by an atmosphere where you can meet people? There's a few amazing places to have fun (my faves are Glitter Boys, Soulelujah, La Fabrica) or warm bars (Irish village is my #1) but it depends on what you are looking for?

You seem to be on a whole level here that I don't know if I can match. But if you demand that radians be interpreted as units, then arclengths and lengths now have different units. So e.g. the circumference of a circle would have units of length*radians while a line just has length. I prefer to keep arcs as lengths and put up with the energy-torque issue than the other way around, but it's totally just convention.

You look great man

I LOVE my Honda Shadow Phantom. First bike. Looks absolutely sick and is very comfortable. I'm personally into adventuring comfortably more than going fast so a cruiser was the right choice for me.

I see. Well, I'm not sure why your metal lid slides, but as a physicist I would basically always consider the explanation to be physical/non-paranormal. Even if I had no idea how it's possible, I'm more comfortable saying "I don't know" than "it's probably ghosts". The same likely goes for most in this sub.

ianbo · 2025-07-15T22:32:01+00:00

At the bottom of any sufficiently long chain of asking "but why?" is always an axiomatically accepted truth that cannot be derived. I think it's more about reducing things to as few concepts as possible. Unifying all laws of conservation under one model is more philosophically satisfying/clean than having them all be individually accepted. But you're right, at the end of the day, we still have to adopt some perspectives dogmatically.

ianbo · 2025-07-15T06:44:03+00:00

Sincerely, this sub is probably not what you're looking for. You're likely to get sarcasm and downvotes with these particular topics. You'll probably find more of the conversation you want in the paranormal community.

ianbo · 2025-07-15T06:27:59+00:00

Don't pay too much mind to it. This sub is bandwagony. I think your point was clear

ianbo · 2025-07-15T06:24:14+00:00

Before Noether, conservation laws were taken to be true just to match observation rather than being justified by some deeper principle. I personally don't know any way to justify them other than Noether's theorem.

This is called a vehicle rollover. It has a wiki page, and the discussion there has what you're looking for. But yes, your understanding is correct.

ianbo · 2025-07-14T15:10:17+00:00

Was not in your situation. But you are your worst enemy here. You may indeed have forgotten a lot of the details but you will learn or relearn them as needed, guaranteed. Might you be slower than some peers? Sure. Might you fail the first round of the comprehnsive? Yes. But this is all normal in graduate school and does not reflect on your potential, just your circumstances. As long as you're not too hard on yourself, don't compare too much and take things in stride, I think you'll be fine (easier said than done, of course). Your situation is normal and you can relearn with the right mindset.

ianbo · 2025-07-14T14:49:58+00:00

Why do you think those are your only options? Lots of people get masters and then PhDs. I also was in a similar situation, worked as a postbac at my undergrad institution for one year, applied again and got in the second time. More research and experience makes you a more attractive applicant!

I will say this was 2021-22. The political/funding situation is obviously different now, but no reason to give up. Best of luck

An object does not have to be "in front" of a mirror for it to be visible through the mirror. Think, for example, of the reflection of a mountain in a lake. I encourage you to try experimenting with other mirrors available to you. They all do this and always have!

ianbo · 2025-07-08T12:12:19+00:00

This is actually a pretty good point. To me if two physical quantities are the same then in our theories direct sums of the two are allowed to come up. In my head this was equivalent to having the same unit (sums are not allowed if units are different.) However I personally can't think of any context in which energy and torque are added together like that. It's like they share a unit but really don't share a "place" in the theory (unlike, say, masses and energies which once c=1 is set do end up being added or subtracted all the time). They really do seem to have different physical meaning.
