Hello. I have just read a mean free path (a distance) written in units g/cm^2. How do you interpret this unit in terms of the usual idea of the mean free path as a distance?

Hello. Do you know any textbook about Statistical Mechanics that discusses Boltzmann Transport Equation? It is not discussed in the textbooks that I know. Thank you.

I am looking for a textbook that gives a good description of the cosmic rays hitting the Earth. Do you have any suggestion? Thanks.

Is that the only motivation? It can't be...

Imagine that I have a system that is described classically by a given Hamiltonian which is a function of a given set of parameters q and their canonical conjugate momenta p=\frac{\partial L}{\partial \dot{q}}. Then, I will say that the quantum description of the same system is guided by setting...

I am looking for a textbook that introduces and discusses the path integral formulation of non-relativistic quantum mechanics? Would you have some suggestions for me? Thanks.

The Klein Paradox is the name given to the following prediction of Klein Gordon's equations. If you send a current of electrons against a potential barrier of height V such that the energy of the incident electrons is less then V - m, you should observe a current of positrons coming out of the...

Hello! I know that the theory of complex analysis is useful to compute integrals of real valued functions. I am a Physics student and I followed a Complex Analysis course but we did not have time to cover this up. I am looking for a textbook that takes a practical approach to this subject. I...

Are you confortable with the demonstration in page 19 of Introduction to Modern Cosmology - A. Liddle ? My problem is in particular eq. (3.4) when he writes the potential energy of a test particle. I think there is a factor of 2 missing in the denominator.

Thanks!

Hello! In which textbooks about Cosmology may I find information about the constitution of the cosmos and also about determination of distances and luminosities? Thanks for your attention.

Sometimes I find useful and more interesting to read a less rigorous textbook before tackling a reference textbook of a given subject. Having said that, I am looking for a book that introduces the ideas of quantum field theory in a relaxed way. This allows to grab the ideas and then formalize...

Hello! I am a physicist. Although I think I understand quite well the laws of Newtonian physics and general relativity that explain the observable universe, I am a complete dummy in what concerns doing measurements in the universe. For instance, I have no idea how to measure the distance to a...

Of course! I am just asking which of the two master's I mentioned would be preferable if your goal after the master's degree is to do a PhD in the US.

Hello! Suppose that your objective is to do a PhD in an american university, one of the top to be exactly. Imagine you have to opportunity to chose between Cambridge Part III and Perimeter Institute master program. Which master would be the best way to achieve the stated goal? What would be the...
