    How is heat caused by photons?

    its because of the vibration when they bumb into eachother, and causes heat. try rub your hands together- the atoms vibration because they push against each other & oscilate untill they retain there original structure.

    How much energy could be stored in a superconducting ring

    The total magnetic energy also includes an amount approximately equal outside the spherical volume V, so: (1/μ0) B2V = 1.8 x 1010 Joules or B = [μ0 x 1.8 x 1010 Joules/V]½

    Time propagation

    I'm running a simple limiting case of a simulation with the expression: exp(-i*H*t), where H is the hamiltonian, in this case a 2x2 matrix of zeros. Should this evaluate to 0, or to [ 1 1 ; 1 1] ? Right now my sim uses the latter, which I'm sure is wrong. What do you think? Thanks in...

    Kinetics Modeling

    In a paper, I encountered a system modeled by six coupled first-order differential equations like so: \frac{dm_i}{dt}=-m_i+\frac{\alpha}{1+p^n_j}+\alpha_0 \frac{dp_i}{dt}=-\beta(p_i-m_i) , where i=1,2,3 and j=3,1,2. According to the paper, the system has a unique steady state which becomes...
