Does Mathematics have the strength to reflect actuality?

Mathematics is portrayed as the queen of science. Being a student of mathematics, there was a time when I used to take pride in such a claim. I was taught that mathematics holds the magic key to...

Where do we stand really in terms of research publication and impact factors?

Being a researcher is it publication or impact factors? I know sensible people would argue one should always concentrate for good work/publication and not think for those impact factors because...

Vorticity and potential vorticity what is the best way to understand the difference?

With linear shallow water theory (LSW) we find del(omega)/del(t) = 0, that is vorticity is preserved, whereas if we consider non-linear shallow water theory (NLSW) it is the potential vorticity...

I would like to know about wavelet transform. There are many books but can anyone tell me about an introductory book on this?

I am really unaware about wavelet transforms and rather curious to know their relevance and advantage over Fourier and Laplace transform. What edge do the wavelet transforms provide over the well...

Is shallow water approximation valid for the large water depths if the wavelengths are sufficiently long?

The development of shallow water equations are seen to be nonlinear at the first step of approximation with the requirement of the parameter epsilon = (n^2)/(m^2), to be sufficiently small, where...

Apart from the carrier greenspan transform of non-linear shallow water (NLSW) equations, is there any other method to linearise these NLSW equations?

It seems the mathematical analyses of waves generated by sea surface or bottom disturbances may be related with a single transformation, although I don't know that. There is a hint of this kind of...

Convergence of an infinite series, each term of which is a product of two infinite cgt series. Product taken needs not be of consecutive terms.

Wish to know the convergence of the double series {anbn}, where {an} and {bn} are both convergence series. The point is the product shown by anbn needs not to be termwise. There may be other ways...
