    Noob with a question about lightspeed travel.

    I'm no expert, but from what I can tell, the apparent difference in time would be made up during the acceleration up to and the deceleration from 0.999c. Otherwise you would end up with paradoxes. One I can think of off the top of my head if the time difference was not compensated for is a...

    How does drug use vary among different populations in the United States?

    I thought of this a few days ago, and just thought that it would be interesting to get some statistics about it, and see how much the statistics here vary with those for the rest of the average population. Feel free to tell as much or as little as you please.

    Schrodinger's equation problem

    \frac{\partial^2 \psi_1}{\partial x^2} \psi_2 = \frac{\partial^2 \psi_2}{\partial x^2} \psi_1 \frac{1}{\psi_1}\frac{\partial^2 \psi_1}{\partial x^2} = \frac{1}{\psi_2}\frac{\partial^2 \psi_2}{\partial x^2} Which can be split up into two equations... \frac{1}{\psi_1}\frac{\partial^2...

    Schrodinger's equation problem

    For the last part, just divide both sides of the equation by \psi_1 \psi_2 and then you will end up with two separated differential equations. All you then need to do is show that they have the same general solution, and that there is just a phase factor between them. The other stuff looks...

    Medical The worst disease ever in human history

    lol. There is some serious religion/atheist bashing going on which I personally find quite amusing. I'm not going to get involved in it, since the original question was not "which has killed more people... religion or lack of religion". With respect to the original question, could genetic...

    Changing filesystem of USB drives

    I found some USB removable storage drives a few days ago, but they won't work on windows. Windows acts as though they haven't been plugged in, so I tried having a look at them using linux, and I can see everything to do with them etc. I now know that the filesystem used is "vfat" (i've never...

    Get the contents of a file, character by character

    o right. sorry. int main(int argc, char *argv[]) { int i; char string[*argv[3]],c; if(argc < 3) { usage(argv[0]); exit(1); } ifstream b_file(argv[2]); b_file >> c; cout << c; cin.get(); } void usage(char *cmd) { printf("Usage: %s <file to read with complete path>...

    Get the contents of a file, character by character

    I am stuck on a program where I need to open a file, and print out the contents to a screen, but at the same time, I want to save each character in the file (spaces included) to an element of an array. However, I am having a problem opening the file and going through it character by character (I...

    I want a new graphics card, but don't know if PCI slots will be ok

    I was thinking of buying a new graphics card, but I had a quick look in my computer earlier today, and I have some PCI slots on the motherboard, but all the new graphics cards use PCI express. Will there be a problem trying to install a new graphics card on the motherboard I already have?

    Using Runge Kutta Method for T.I.S.E in Electron Motion Approximation

    Siddharth. Once again, you have no idea how useful your posts have been. Thank you. That cleared up a lot of problems I had.

    Can Divergence Exist Without Magnetic Monopoles?

    I always thought that the absence of magnetic monopoles was just the assumption that they don't exist, based on the fact no1 has ever observed one, and so the 'law' that magnetic monopoles don't exist (or at least aren't thought to exist) was just the result of physical observation.

    Using Runge Kutta Method for T.I.S.E in Electron Motion Approximation

    I would be very very grateful to have a look at your program, I will study euler's method, see if that helps. I understand the principle of how the ruger kutta method works, but all the examples I have involve 1st order differential equations, I have a second order, and I'm not sure how you deal...

    Using Runge Kutta Method for T.I.S.E in Electron Motion Approximation

    Homework Statement I really am desperate for help on this one. I need to use the runge kutta method to approximate the motion of an electron in the potential below. The T.I.S.E is known, and I have to try and use the runge kutta method to find the wavefunction of the particle. V(x) =...
