    The equipotential surface of a system of two unequal charges

    We have a system of two unequal oppositely charged point charges, of which ##q_2## is smaller and ##d## is the distance between charges. There is an equipotential spherical surface of potential ##V=0## that encloses a charge of lesser absolute value. The task is to find parameters of that...

    Style Guides for Physics & Computer Science Texts

    Thanks. Maybe I should look into The Chicago Manual of Style?

    Style Guides for Physics & Computer Science Texts

    If not official, then unofficial, but widely accepted? If yes, are there some separate style guides for physics and computer science texts?

    Two formulas for calculating root of a complex number in a exponential form

    z_k=\sqrt[n]{u}=\sqrt[n]{r}e^{i\left(\frac{\phi+2k\pi}{n}\right)}, k=0,1,2,...,n-1 and z_k=\sqrt[n]{u}=\sqrt[n]{re}^\frac{\phi+2k\pi}{n}, k=0,1,2,...,n-1 Which one is incorrect (note that in the first, e is out of the root)?

    Can MAME run the same games which MESS can?

    I am taking about MAME - Multiple Arcade Machine Emulator and MESS, which is based on MAME as its core (MESS stands for "Multi Emulator Super System"). Both are software emulators for video games. MESS supports many platforms and I am wondering does MAME supports the same platforms, since...

    Question 2: The second question is about equation which describes a wave in air which originates from vibrating string attached to both of its ends and strained by some force.I know that people in United States and UK represent this equation in different form,so I`ll describe every...

    Various problems & questions - help,suggestion?

    Question 1. From kinematics we have a=\frac{\mathrm{d}^2s}{\mathrm{d}t^2} which means,as I understood it:to get the acceleration,we first derive distance with respect to time,then again derive the result of that operation with respect to time. If so,wouldn`t be more appropriate to write...
