Hello all. I am wondering what my chances are of getting into grad school. I realize there are other posts on the topic, but everyone is in a different situation so I think this is warranted.
I have what the university calls a combined honors mathematics and physics BSc degree from the...
Ok, so I am wondering what an engineer really does on the job. How much of it is actual engineering, how much of it is paperwork, meetings, talking with clients, or whatever? I would appreciate it if only people that are working in engineering respond.
Thanks.
Can someone tell me what Doping away from half Filling means? I see it everywhere. Although I can't find referance to it in Kittel or Mermin, although I might not be looking hard enough. I have and idea of what it is. Half filling refers to the doping where the Brillouin Zone is half holes and...
So, i've noticed that when I freeze ice cubes these strange icicles appear on the top of the ice. I took a picture, included as an attachment.
Not really sure how something like this forms. Please no speculation.
So ive been working on this problem. Im given the metric in Kruskal coordinates, so
ds^2=32M^2exp(-r/2M)/r(-dT^2+dX^2)+r^2(dθ^2+sin^2(θ)dΦ^2)
And the path of a particle is
X=0 T=λ θ=π/2 Φ=0
And the path of the observer is
X=-1/2*T+1/2 θ=π/2 Φ=0
And im asked to find the 3...
4-velocity --> 4-acceleration?
Hey all, my first post here.
Now, Im trying to derive the 4-acceleration from the 4-velocity by explicitly calculating du/d(tau). So from Hartle we have
u=( gamma, gamma*v)
where gamma=1/Sqrt(1-v^2)
and v is the 3 velocity, taking c=1
So then...
