Ya, Norman. I do need to incorporate fringe benefits as well. If you happen to have your proposals easily at hand then that would be great. If not, don't worry about it.
The PhD is not necessarily in physics. In this particular case, we have a Biochemist, a Physicist, and a Materials...
So I have to put together a mock budget for a funding proposal. I am unsure, however, how much I need to pay the research assistants I will have working on the project. I also don't have a good idea of how much a professional with a PhD or master's would be paid to work on a project.

Doe anyone have any actual research experience? Like the guys above said, what can you actually do with only a couple years of undergraduate education?
Hi guys,
This summer I am looking to get involved in research at my university. I am eager to go and meet with a professor to see if I can hold a position for him, but I am very intimidated and I sometimes feel like I don't know enough to contribute to a research team. I have been told...
Okay, so I think I figured out my problem. I was doing something wrong with the component form.
Here is what I got for my inertia tensor:
I_11 = 0
I_22 = (1/3)ml^2
I_33 = (1/3)ml^2
I_12 = I_21 = 0
I_13 = I_31 = 0
I_23 = I_32 = 0
So it looks something like this...
Homework Statement
A thin rod has mass M and length L. What is the moment of inertia tensor about the center of mass if placed along the x axis.
Homework Equations
I would write the inertia tensor in component notation, but I don't know how to use Latex.
The Attempt at a Solution...
I don't think it's an algebraic error. I have worked the problem through, once using endpoints x=0 and x=L and again using x=-L/2 and x=L/2 and I don't get the same answer.
In the case where I am going from 0 to L, I get that the energy is E=(n^2*h^2)/8mL^2, which is correct.
In the case...
Homework Statement
Find the energy of a particle of mass m in an infinite square well with one end at x=-L/2 and the other at x=L/2.

Okay, so v dot u in the denominator will be zero, leaving just the 1. However, I'm still confused about u(perp) and u(para). Wouldn't u(perp) just be u and u(para) just be zero?
Homework Statement
One particle is shot in the x direction at speed u and a second is shot in the y direction at speed u as well. Show that the relative speed of one to the other is: u(2-(u/c)^2)^1/2.
Homework Equations
velocity addition: u = (u' +/- v)/(1 +/- u'*v)

Each of the spaceships are moving towards each other. So the ship that launches from x=0 is moving towards x=4 and vice versa. I am giving the coordinates as (x,t).
Homework Statement
Two rockets are sent off at t=0, one from x=0 and the other at x=4. The rocket leaving from x=0 is moving at .8c and the rocket leaving x=4 is moving at .2c. When the paths of the two rockets meet, they send a light signal to x=0. Read off the coordinates in the S frame...

Sketch the elliptical and hyperbolic orbits two objects make around each other if their masses are equal. Next to each, sketch the equivalent one-body orbit.

For the elliptical orbit, I just drew two ellipses that...
Okay, thank you. That is what I was looking for. I just wasn't sure if I had to treat my r' as another variable or if I could consider it to be constant with the 2c. Thanks very much.
Homework Statement
z = cr^2
Homework Equations
The Attempt at a Solution
I have a pretty simple question. What is the second derivative of the z equation.
I know that z' = 2crr'.
Am I correct to say that z'' = 2cr'^2 or is it something else?
Hopefully my question...
So I still don't see what the point of finding this equation was. I was able to find the Lagrangian and go through and solve for the equation of motion all without having this equation.
Homework Statement
A simple pendulum has a mass M attached at the end of a massless rod of length L. Find the force of constraint the rod exerts on the bob.
Homework Equations
The Attempt at a Solution
It seems easy enough that the mass is constrained by the tension the rod...

What I'm saying is:
x(t) = Ge^(i\phi)
x(t) = G[cos(\omegat - \delta) + i*sin(\omegat - \delta)
Then taking only the real part of this:
x(t) = Gcos(\omegat - \delta).
From here, I can compare to the given solution of x(t) = Dcos(\omegat - \delta) and say that G = D.
Does this...
Homework Statement
Show that the solution x(t) = Ge^(iwt), where G is in general complex, can be written in the form x(t) = Dcos(wt - \delta).
D(w) and \delta(w) are real functions of w.

z = Ae^(i\phi)

Homework Statement
The oscillator is driven by a force F(t) = mAcos(wt). Plot the amplitude D of oscillations, in units of the maximum (resonant) amplitude D(max), as a function of w in units of w_0. (In other words, plot D/D(max) versus w/w_0.) Find Q.
