Research assistant hourly wages?
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...- w3390

Research assistant hourly wages?
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. I...- w3390

Undergrad Research: Overcome Intimidation & Enjoy
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...- w3390

Calculating Moment of Inertia Tensor for Rod Along x Axis
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 = 0So it looks something like this: [..0...0.....0...]...- w3390

Calculating Moment of Inertia Tensor for Rod Along x Axis
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...- w3390

Energy in infinite square well
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...- w3390

Relative speed of two particles
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?- w3390

Relative speed of two particles
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) Lorentz Trans...- w3390

Analyzing Spacetime Diagrams: Finding Coordinates and Checking Invariance
Yes, you're right. I had drawn my line incorrectly. Instead of drawing it as .8c I drew it as 5/4 c. I've got it now. Thanks.- w3390
