    Why do couplings run with log of energy?

    In fact, it is the other way round: You know for sure, that the theories we construct suffer from being well-behaved either at low or high energy limits. As a consequence, many of the integrals are divergent (either IR or UV). To get a proper meaningful theory out of these divergent...

    Spinor Decomposition of a tensor

    Hi, I have heard, that a second rank tensor can always be decompose into a spin-2, a spin-1 and spin-0 part, being reducible. I want to pursue this further. Can anyone suggest me a nice reference for it? TIA Nikhil

    Understanding Reddening and Its Impact on Light Scattering in Astronomy

    Reddening Hi, It can be understood this way...You know, that for EM waves, E=h\nu. where \nu is the frequency of the wave. Now scattering goes as inverse square E and hence as (\nu)^(-2). Hence the result..."Shorter wavelengths scatter more". Now, this means blue will be scattered more...

    Multivariable Calculus: Conceptual Question on Total Change in a Function

    Actually, what you are not taking into account is that z(x,y) is a function of both x and y, while you wrote the differential form of z in terms of the partial derivatives of it. The partial derivatives do not come naturally as an straight forward extension of one variable case, since in...

    Why is the ground state eigenfunction in a symmetric hamiltonian also symmetric?

    Hi, Why is that, the ground state eigenfunction in ANY quantum mechanical system is symmetric under inversion of co-ordinates?

    Is the Speed of Light Constant? Exploring the Scientific Debate

    Hi, No Russ. I have to disagree with you. Though your explanation is partially acceptable, it is not relevant in this case. When one is talking about the constancy of the speed of Light, he is talking about the ultimate speed of propagation of information by any means. That is the...
