    Photoelectric Effect in a Circuit

    I have recently been reviewing the photoelectric effect in a circuit in which a metal target has a light directed onto it, and any resulting electrons flow through an empty space to a second target, completing the circuit to which a battery is also attached. I have, however, had a few conceptual...

    Credit Transfer for High School Students: Math and Engineering Credits Explained

    I'm currently a high school student, but have several credits from a local university, mostly for math and some from engineering. If I want these credits to transfer to where ever I end up going to college, does the credit alone transfer (by which I mean does it simply count towards fulfilling...

    How Do You Find Isometries in Relativity?

    Is there any way you can find the isometries with just the equation for the metric space though (instead of using a metric tensor)?

    How Do You Find Isometries in Relativity?

    This is really more of a general question about the process of solving a certain type of problem than it is an actual problem. Concerning invariance of the interval, ds, in relativity, say you have an interval ds^2, ℝ(1,3), and a certain equation for a metric space. I know that there are...

    How can I graph this equation (Rayleigh Plesset for sonoluminescence)?

    I tried Wolfram Alpha already, but it seemed to interpet what I was asking rather strangely; of course, it is quite possible that the way I typed it was less than perfect... I guess I'll have to either find a way to get Mathematica or solve it on my own. Thanks though!

    What exactly is the relation between LQG and the Friedmann equation?

    Thanks so much :). And don't worry about it, feel free to take your time! No rush here, just a leisurely interest, for the moment.

    Is mathematics a young man's game?

    Functor97, I don't have much useful advice, but if it is any condolence, this is exactly the way I have been feeling for the past year or so (if you replace "mathematics" in your case with "physics" in my case). Strangely though, I am a few years younger than you, so I would certainly not say...

    How can I graph this equation (Rayleigh Plesset for sonoluminescence)?

    The following is the Rayleigh Plesset equation, modified so as to be specific to the phenomenon of sonoluminescence. R\ddot{R} + 3/2(\dot{R}^2 = (1/ρ) (p_{g} - P_{0} -P(t) - 4η (\dot{R}/R) - (2γ/R)) I'm trying to graph this for comparison of maxima and minima (of R) with another graph. If...

    What exactly is the relation between LQG and the Friedmann equation?

    marcus, Thanks so much; your reply really cleared up a lot for me. Might you happen to know which paper deals specifically with the quantum bounce? I've been looking through the others, but there are enough of them that I'm having a bit of trouble finding it. Blackforest, Unfortunately, I...

    What exactly is the relation between LQG and the Friedmann equation?

    Agreed, on the subject of idleness, though you can probably tell that I took more time than I needed to to try to think of an appreciable name :). As for the paper, yes, it is quite long, but I do appreciate the fact that they derive everything, and it is much less absurd a suggestion...

    What exactly is the relation between LQG and the Friedmann equation?

    I'm just beginning to look into loop quantum cosmology, and I've recently run into some fundamental confusion concerning how exactly the Friedmann equation fits in. Is it just that the application of loop quantum gravity yields a modified/effective Friedmann equation, or is it the other way...

    Current and Power in DC Circuits

    Somehow those diagrams turned out horribly. I've attached some better ones; "Untitled" is corresponds to the first problem and "Untitled 2" corresponds to the second. Thanks!

    Current and Power in DC Circuits

    I have two problems that have been bothering me, which I just cannot seem to figure out. Both have to do with current in a DC circuit with multiple resistors. The first one looks like this: 12 V 4 ohms |------:|:|-----\/\/\-----| |...

    Volumes of Solid of Revolution

    Well, I have rechecked the problem's statement in my textbook, and that is exactly what it says. I was assuming though that it meant for me to revolve a triangular area (bounded by y = x, y = 0, y= 4, and x=6) around x = 6. And thank you for the help with the typing of the integrals :]...
