That was an awesome paradox! Too good! And enlightening! Anyway, returning to my question,I understood your point that |x> does not live in the Hilbert space.Thanks! Let us not call the space of wavefunctions for a particle in a box as Hilbert space. Let us call it some space (say space...

Technically, potential energy of a conservative force is DEFINED to be the negative of the work done by the force between two points in space. It makes description of the work-energy theorem(for conservative forces) more convenient i.e in terms of the energy conservation law. You could always...

We know that the Hilbert space of wavefunctions can be spanned by the |x> basis which is a non-countable set of infinite basis kets. Now consider the case of a particle in a box. We say that the space can be spanned by the energy eigenkets of the hamiltonian (each eigenket corresponds to an...

Could anyone suggest a book/lecture notes on the early universe, especially the thermodynamics of it i.e. Big-Bang Nucleosynthesis etc.. I have a book -Early Universe by Kolb and Turner, but I dint really find it readable. Its not exactly reader friendly. But I would be really glad if someone...

Could anyone tell me the equation of state of an electron gas, or where I could read it from? By equation of state I mean a relation between pressure, density etc etc.

Thanks. Any good book for group theory?

Hey thanks a lot.

Could someone suggest a good book for elementary QFT and particle physics?(I don't know which to read first). I have very little idea about QFT. Could someone also tell me what maths knowledge is required?
