    The number of states for N identical particles with energy between E and E+dE

    the answer is NE^0.5 but my answer is E^0.5N the # of state is Ω=( one particle phase-space volume)^N one particle phase-space volume=integration of dq*integration of dp from space part dq I get V and dp is converted into Energy E variable via E=p^2/2m

    Multipole expansion for the case r'>>r and r>>r'

    for the case, r>>r' the higher-order term like 1/r^2 and above that is negligible. so V(r)=cons.*1/r*P0(cos a) but for the case r'>>r will it be V(r)=cons.*1/r'[ summation Pn(cos a')t'^n] where t'=r/r' now if we neglect higher-order term of r/r' then V(r)=cons.*1/r'*P0(cos a') which is...

    A Pauli's spin matrices in higher order

    the question that can we express Pauli's 2x2 matrices for spin 1/2 in higher-order matrices, say 3x3, 4x4 arose in my mind.

    I What is the velocity of light in uniformly rotating frame?

    v=2πR/T now for earth T=86400 sec. and R=4.2 light years i.e. (9.46*1015)*4.2 so,v=2.8*1012 m/s , >c
