    Best Career Path After Physics BS: Job Security & Pay

    If I were to decide that I did not want to go through with a PhD in physics and go into academia, what would be the best career path job security/pay wise. Hypothetically I graduate with a BS in physics with research experience, would it be better to go to grad school for some other field (say...

    Summer Internships Europe 2015

    I am currently an undergraduate at a small physics school in Texas. I'm a freshman, but I'll be graduating in ~2.5-3 years (lots of ap credits/local uni). My parents are in the process of moving to Europe(Italy), and I really would like to find something physics related I could do for the...

    How Does a Laser's Resonant Cavity Create Multiple Wavelengths?

    I ended up just solving for n, and using only integer values of n, and then adding and subtracting 1 integer value, and solving for lambda, until lambda was out of the limits (633.001 and 629.999)

    How Does a Laser's Resonant Cavity Create Multiple Wavelengths?

    so would I just add and subtract 0.001 from 633?

    How Does a Laser's Resonant Cavity Create Multiple Wavelengths?

    Homework Statement The fact that a laser's resonant cavity so effectively sharpens the wavelength can lead to the output of several closely spaced laser wavelengths, called longitudinal modes. Here we see how. Suppose the spontaneous emission serving as the seed for stimulated emission is of...

    Stirling Approximation for a thermodynamic system

    I found what I did wrong, thank you very much for the help. It was a simple algebra mistake when distributing exponents

    Stirling Approximation for a thermodynamic system

    Sorry about that, I screwed up a lot of things in typing it out JJ+0.5e-J√2pi My work probability for a 50/50 distribution is (N!)/((0.5N)!(0.5N)!) probability for a 40/60 distribution (N!)/((0.4N)!(0.6N)!) when you divide 50/50 over 40/60 you get ((0.4N)!(0.6N)!)/((0.5N)!)2 So when I...

    Stirling Approximation for a thermodynamic system

    Homework Statement The stirling approximation, J! = √JJ+1/2e-J, is very handy when dealing with numbers larger than about 100. consider the following ratio: the number of ways N particles can be evenly divided between two halves of a room to the number of ways they can be divided with 60% on...
