Oh wow, I hadn't even thought of that. Thanks!

Could you elaborate on this point a little further? How does the relativity of simultaneity affect the answers to the questions I'm making? Or, perhaps, how have I assumed simultaneity in the way I worded the question?

Thank you, I'll definitely take a look at this.

So that means I replace t by what it equals in terms of t' and x'? Is it really as simple as that? Meaning, take the first component of my 4-velocity. Does it change into (γ_ω)(γ_v)c+(γ_ω)(γ_v)*(v/c)*ωRsin(ω*(γ_v)[t'+vx'/c^2])? That then leads me to another question: how do I check that this...

Do I use the Lorentz transformation formulas to do this? Meaning, t'=γ(t-vx/c^2), etc.? Which γ would this be, then?

Alright. I just didn't want to make it look like a homework post. For the 4-velocity of the circle/annulus, I came up with γ_ω*[c, -Rωsin(ωt), Rωcos(ωt), 0]. Using u⋅u=-c^2 I found that γ_ω=(1-[Rω/c]^2)^(-1/2). So far, this is just a spinning circle of radius R, centered at (0,0). I then...

I'm trying to understand the relativistically spinning disk within the framework of SR (if that is even possible). I thought to first simplify the problem by considering a spinning ring/annulus, but I don't know if my analysis is correct. I imagined a spinning ring of radius R, spinning at an...

The formulas you are using are for constant acceleration, but there isn't constant acceleration overall. There is zero acceleration for the first 9.0 s, and then there is non-zero acceleration from then until the end of the problem. You cannot apply these formulas over the entire interval in...

But the last term isn't V, it's ΔV, so no matter what P is, PΔV for an isochoric process will be 0, because volume doesn't change (ΔV=0). I feel that this is a safe assumption, since you were given CV, which is the specific heat at constant volume.

http://www.algebra.com/algebra/homework/word/misc/Miscellaneous_Word_Problems.faq.question.596257.html One of the steps leads us to A=2x√(r2-x2). The page then says that we could differentiate at this step, but that it would be easier to first square both sides, so as to not have to...

Homework Statement So, I don't have the actual problem in front of me, but from my scribbles I can make out all the information the word problem gave. A plane flies from one place to another with the wind in 6 hours, and back against the wind, in 7 hours. The speed of the plane in still air is...

Thanks, you guys have been really helpful. Although, let me rephrase that question... should photons cease to be bosons and become fermions, for whatever reason, is there anything in the nature of lasers that could go against the Pauli exclusion principle?

So, unless I'm greatly misunderstanding, does that mean two bosons can be in the same place at the same time? What about composite bosons?

No, no one?

As I understand it, the Pauli exclusion principle states that no two like fermions can be in identical quantum states. I also understand that the quantum states are thus: n, which is the electron shell, l, which is the subshell, m_{l}, which is orbital, and m_{s}, which is spin. However, it...
