How was it, and what were the question types?

Especially for those of you working in defense.

For example, Shanghai has the world’s largest planetarium. Would I be allowed to visit?

For example, I know that the derivative of v(x(t)) = v’(x(t)) * x’(t). And that presents itself as dv/dx * dx/dt. But what does that really mean physically? And why does the derivative seem to go from left to right..as in, it starts from dv/dx from v’(x) and then dx/dt for x’(t).

what does this physically mean in terms of position and velocity? and is there a more intuitive way to understand chain rule?

I know those were quite a lot of questions, so I would appreciate any perspectives. Thank you

Does ERAU Daytona provide computers to run CATIA? My computer is inefficient at running CATIA, and is mostly only capable of running Onshape

I want to end up doing work related to GNC. Wholly apathetic and disinterested in CAD, as compared to programming in C & python. I also heavily enjoy mathematics/physics.

I mean, I know you can plug in numbers into a universal law of gravitation formula and centripetal force to solve for velocity. But i’m wondering if there’s a different method via cameras or trigonometry or something else.

Something about a lack of a time-killing vector & cosmological redshift being an observable phenomenon of energy conservation failing? Is this true?

also I know energy is the quantity associated with time translation symmetry. and energy is the ability to do work…so on and so forth

is there a better way to think about energy??

Are Quantum Field theorists just mathematical realists? Or is physical stuff made out of interactions, and QFT is how we mathematically model physical phenomena? If anybody knowledgeable on QFT can give me a better way to frame this inquiry, I’d deeply appreciate it.

just curious as to why I can’t find any videos of this and if it has ever been done….I checked many websites and panasonic timelapses, I looked on youtube, and yet I cannot find a video of the ISS coming up and above the horizon. Or meteors, for that matter.

If not possible/realistic, why not?

I want to learn everything from Lagrangian mechanics to QFT. Physics seems so unbelievably appealing, however there is a lot of fear around the job market and employment rate for physics graduates.

I’m sure you guys get a lot of these types of posts but I might as well utilize the internet as a tool to get feedback. Is physics worth it? Should I just stick to engineering (even though i’m wholly apathetic about design and CAD).

edit: i’m sticking to aerospace engineering. i’ll just try to get a minor in physics
