The image is below. My question is, why he considers ##p' = p## on the RHS of ##(2.5.14)## but not on the LHS, i.e., the sub index on the left ##\Psi## remains ##p'##. Is it a mistake? And he continues on the derivation (not shown here) even considering ##|N(p)|^2## instead of ##N(p')^*N(p)## so...

I came across this book 'Street fighting Mathematics, The art of educated guessing and opportunistic problem solving' , by Sanjoy Mahaan, published by MIT press. The book talks about how we can guess some property of the solutions of a number of physics and math problems without actually solving...
Hello my friends,
I am studying excitability in quantum dot lasers and I see a lot of bifurcation diagrams with saddle node bifurcations, Hopf bifurcations, homoclinic bifurcations, PD bifurcations etc. I know some basic things about non-linear systems but I have never met the notion of...
Hello! Currently I own Differential Equations by H.B Phillips, a really old book, but difficult and does it´s purpose. I have only 1 problem, certain exercises require certain geometrical functional study I suppose, for example:

Hi everyone, I am a 10th grade student studying in India( would be in 11th in 2 months)I am not very good at chemistry. I have difficulty understanding the concepts. Although I don't have any doubts, I just don't feel confident. Also, my teacher is not very good. Whenever I would ask him...
Hello All,
I recently purchased a book on relativity called "Gravity in a Nutshell" by Zee. While it is interesting I find his conversational style to be too chatty. I prefer a little more of a "get to the point" conversational style.
I'm going to be modeling the evolution of the...
I want a book that explains everything about
Michelson Morley experiment. The one that says
light moves with c regardless of the speed of the source
and also the one that says light appeared to move with
C for all observers.
Hello. I was studying magnetism with the 9th edition of the Serway book and I think that I've found a mistake. In the cathode ray tube example (one of the uploaded pictures) it is said that the force acting on a electron goes downward, but using both right hand rules that they provide in the...

Hi everyone! First of all I want to congratulate @Orodruin for his book publication! I myself thought that maybe someday, I would like to write a book. So I became a little bit curious about other titles that may have been written by Physicsforum members. I hear Benjamin Crowell is also a member...
Hi,
I've taken calculus during my engineering degree (that I'm still attending) two years ago. At that time I didn't realize the importance of calculus (and also linear algebra) so I studied it superficially. I think I'm quite good though because I had to use my calculus knowledge in all the...
I am searching for a good book that could be used as an introduction to the dynamics of swarms and maybe their self organization. I am a physics junior and would like something that is decent for that level.
I am in a small school in North Dakota and will have four students in the class next year. I have been here two years after retiring from another state. Two years ago they took an online physical science class and from what I can figure out they learned very little to use for background. They...

I have read( even Peter Donis mentioned it) that the derivation of the potential between two particles is not a true QFT, why is that? if not, then what is it?
Thanks in advance.
This article (in the picture) states that the end of a compass needle which points toward North is its south pole since the Earth's "magnet" has a North magnet at the North. But in reality, there is a south magnet pole (not sure about that terminology) near Earth's North Pole, attracting all...
I have read about general relativity, quantum mechanics, and physics is general, but I'm looking for a book that goes a little bit more in depth with the math behind the theories (I understand a lot of those equations are going to be complicated). I'm in 10th grade so I'm doing Algebra II this...
