    Testing Missed My Physics GRE Signup, What To Do?

    Okay thanks for the advice so far. I've been really interested in going abroad to get my masters, they don't seem to require any GRE. Would it be a good idea?

    Testing Missed My Physics GRE Signup, What To Do?

    I am graduating with my BSc in Physics next spring and I want to go to graduate school. The problem being that I missed the sign up date for the Physics GRE, I did however, take the general GRE. What can I do now to get into graduate school?

    Approximation of values from non-closed form equation.

    Oh okay, thanks JJacquelin, I didn't even think to do this.

    Approximation of values from non-closed form equation.

    Hello everyone, I'm working on a problem and it turns out that this equation crops up: 1 = cos^{2}(b)[1-(c-b)^{2}] where c > \pi Now I'm pretty sure you can't solve for b in closed form (at least I can't), so what I need to do is for some value of c, approximate the value of b to...

    Understanding field representation of force

    Gravity doesn't just happen along those specific field lines. It permeates through all space continuously. What that drawing is telling you is that the density of the lines is related to the strength of the field. It's simply a visual aid, you can't make any direct calculations from it. 1. Yes...

    The Human Double Slit Experiment

    I thought it was fairly clear that he meant the time in between firings. Thanks for both of the answers, I'm starting to get it now. Or at least I think I am :)

    The Human Double Slit Experiment

    Okay it's been well established that objects with momentum exhibit wave like properties. Hence, electrons being observed forming interference patterns when scattering off of crystal lattices. Also I recently read this webpage. At the bottom it mentions performing a double slit experiment with...

    The jewel found in Quantum mechanics?

    It says what they found right on the first caption of that link from bhobba. The geometrical properties give rise to probability distributions of the outcomes of particle interactions.

    Heisenberg's Uncertainty - ΔλΔx

    Oh man I didn't even see his post. :rolleyes: As it happens, after my original post, I read the Wiki page on black bodies, which has a section about cavity radiation. But I appreciate the answer and wish I'd have actually seen it.

    Heisenberg's Uncertainty - ΔλΔx

    Okay thanks a lot, I'll have to be more careful in the future. I'm going to start using the sigma notation instead of delta, just to remind myself.

    Heisenberg's Uncertainty - ΔλΔx

    It's he :p So I'm not allowed to use them as differentials? My modern professor has done so on a few occasions to get at a couple more uncertainty relations.

    Heisenberg's Uncertainty - ΔλΔx

    So we have a light bulb emitting through a small slit. I read somewhere that a blackbody shining through a small slit acts like a perfect emitter, and I wanted to know why. I figured it must have something to do with Heisenberg's Uncertainty. Here's how I went about it: \Delta x\Delta p \geq...

    SpectraSuite & Blackbody Radiation

    Hello, me and my friend have been doing a lab where we are measuring the wavelengths of light emitted by a blackbody. We are using the OceanOptics 4000USB spectrascope with the SpectraSuite software. The only problem we are having is with the software, it plots the wavelength on the x-axis and...

    Finding heat lost when waters of different temps. Are mixed

    Well, the heat lost by the water will be measured in units of energy, not temperature as you may think. Do you remember this guy? Q=mc_{w}\Delta T

    Second Order Nonhomogenous Differential Equation

    Thank you for spelling this out for me. It already is starting to make more sense. I'll have to spend the next couple of days studying your reply though, as I am busy all weekend. :)
