Hi. I bought Messiah's "Quantum Mechanics" because it was at an excelent price from Dover. But, even though it was considered a Bible of quantum mechanics until recently, people consider it outdated now. Is it no longer comprehensive? I intend to read on relativistic quantum mechanics and...

Dear all, I am looking for an introductory QED textbook (or quantum optics if not) that also covers QED cavity and Purcell effect in one of its chapters. I am not planning to extensively understand every single detail about QED cavity and Purcell effect since I am not a physicist and I don't...

The book is called "Analytical Combinatorics". I have read a description of some of its subject matter and it sounds super interesting. Here is the pdf: http://algo.inria.fr/flajolet/Publications/book.pdf It sounds really interesting but I don't think I'll have the time to read the whole...

your second question seems like an excellent introduction to Vandermonde Matrices. I wouldn't recommend solving this 5x5 matrix by hand. With some cleverness you can get it down to a 4x4 matrix but still a lot of work to do by hand. A good computer exercise. It would be worth learning to...

My first question is about a formula for the y intercept of a linear equation, given you know two points that the line goes through. I Googled but no luck - it's hard to type a formula into Google. The formula is: b = (y1*x2 - y2*x1)/(x2 - x1) The textbook author left this as an "exercise"...

I'm about to transfer from a community college over to a university this semester for physics. I've completed all lower division physics and math courses and of course, I missed the deadline to apply for vast majority of physics related internships I could get. Add to that the fact that there...

I'm working through Gregory's Classical Mechanics and came across his derivation of energy conservation for a system of N particles that is unconstrained. We get to assume all the external forces are conservative, so we can write them as the gradient of a potential energy. There's a step he...

Hello,Lately, I have been interested in philosophy and in particular the branches of philosophy where there is a tie with mathematics and physics. From this point, I think the best branch to start studying would be the most robust one for scientists. i.e Logic. But I am having a problem finding...

Homework Statement Homework EquationsThe Attempt at a Solution I am not following what is going on here, how are they getting that part that is circled. i am just completely lost here

I really liked this book but the problems don't have answers at all (not even numerical one's at the back of the book). There is not even a solution manual to download or buy online. How am I supposed to use this book otherwise?

Hey guys, I was wondering if this textbook is good. I've seen the reviews and it has high stars. I want to learn proofs so I self-study and make my way to finally learning real analysis. I'm a chemistry major with a concentration in Math and economics. My plan was to do a double major in math...

Hi guys I was wondering if anyone had a good recommendation on a textbook to pick up on field oriented control, motor control, 3 phase control or modern motor control in general. Looking for a professional level text. I already have Electric Machinery Fundamentals by Chapman but looking for...

I am seeking an undergraduate and graduate text for solar astronomy and astrophysics. By solar, I mean the Sun. Quantatative, too. Recommendations and testimonials appreicated. Thank you,.

Hey, I am a physics major and a new semester is about to begin. I think my biggest problem study wise is that I would go over the lecture notes and sometimes the textbook too, yet always feel ill equipped to tackle the homework problems. Currently my strategy is to go over the text...

Hello! I’m teaching myself mathematics and physics, and I’m looking for a clear, rigorous book on combinatorics. The reason being is that past books I’ve read that included some combinatorics were difficult to understand (for example, my first encounter with the subject was in a precalculus...

I just got a taught Master offer in Physics (part-time mode for 2 years) and I don't know what to do... First of all, I have a BSc in Applied Physics which I graduated in 2011. I study Physics because it is interesting. I felt happy when I got to understand something new (about the universe)...

Hello fellows My background is architecture (bachelor in2016) but for unknown reasons I’ve been fascinated by geometry since last year. it was roughly at the stage where I was trying to grasp ‘the truth ‘ of architecture and somehow got into geometry... happy coincidence. Since I hadn’t...

I sometimes post answers to threads people post about E&M. Unfortunately, my Masters in physics was 40 years ago and I am a little rusty. I am looking for something that will help me answer people's questions. The level of math can be fairly sophisticated as I have brushed up a bit.

Hi I have a question about electric potential! Since the negative sign isn't used in U=qV, and a-b is used for subscripts, then that takes care of the negative. But what about using U=-qV? An online lecturer uses U=-qV, while my textbook uses U=qV and then uses -qV to explain the force used to...

Currently a fourth year undergraduate student and haven’t had the opportunity to take any Astrophysics courses. In September I am starting a master’s degree in Physics but with an Astrophysics research project. I am told it is fairly easy to learn all the Astrophysics stuff in the first few...

I am seeing this formula in a textbook, unexplained. Can someone tell me the origin, the book just says it is an identity. $$Re(Ee^{jwt})=\frac{1}{2}(Ee^{jwt}+E^*e^{-jwt})$$ The book doesn't explain what ##E^*## is, it just lists the formula. Re = real, as in take the real part. E is the...

Hi guys I've recently started a module called variational methods, here is the module summary. Is there any resources you guys can recommend to help me learn all the relevant info for this module? Thanks in advance

Hello everyone, This is my first post and I would like to briefly introduce myself and my situation. I'm 27 years old and a high school drop out, former drug addict, and three time college drop out. I have severe ADHD and insecurities which have made academia too difficult for me to pursue. I...

Hey friends, taking a class on semiconductor fabrication and my professor both can't teach and doesn't use a textbook. I'm going to take it upon myself to learn the material independently, so can anyone recommend a good textbook on the subject? Thanks in advance!

Hi, I just acquired the art of problem solving prealgebra book. So I would like to ask, how does one use the AOPS books, are they meant to be supplementary to a full textbook? Or are they used for introducing new concepts that you would have leant in a textbook etc. I am hoping to use the AOPS...

I am self studying Classical Mechanics and I am a bit confused about this. After reading Kleppner Kolenkow Mechanics can I read Symon's Mechanics or do I need to read anything in between like Fowels or Marion&Thornton? I already studied the Maths portion upto Multivariable Calculus,Real...

Hello, currently I am a high school senior who will be going to college in the fall and since my school ends in may and college starts in mid-August. I am planning on self-studying calculus 3, so I can test out of it and go straight into partial differential equations. The textbooks that the...

Often when I read a chapter in a textbook and don't understand something, I find "reading notes" by other students extremely helpful. Oftentimes in these notes other readers have simply written down summaries of the sections in their own words. These descriptions of the "same thing" in...

I'm trying to work through a scattering calculation in the Peskin QFT textbook in chapter 5, specifically getting equation 5.10. They take two bracketed terms 4[p'^{\mu}p^{\nu}+p'^{\nu}p^{\mu}-g^{\mu\nu}(p \cdot p'+m_e^2)] and 4[k_{\mu}k'_{\nu}+k_{\nu}k'_{\mu}-g_{\mu\nu}(k \cdot...

I'm currently doing a literature review on ultracold chemistry with an emphasis on collisional theory and quantum phenomena. I'm an undergraduate physics major, and I'd start my discussion of this topic by moving from basic Newtonian conservation laws and concepts like Coulomb repulsion to the...

Hi everybody. I enjoy looking at other people's handwritten notebooks, as well as what textbooks they learned math and physics from. This evening I came across this article about how Feynman learned calculus in high school by studying Calculus for the Practical Man by Thompson. He kept very...

Hi there, I have been searching multiple websites and forums but have not found a cohesive answer to my queries. I am currently going through this textbook to learn pre-algebra: https://www.amazon.com/dp/0618250034/?tag=pfamazon01-20 Also, is this a good book to be studying as an autodidact...

I was given as a task to solve this question by my teacher (heck if I had the time I would have solved every problem in both Taylor's and Evans's books on PDE); but didn't succeed to the teacher's satisfaction. In the following link there's a presentation of the problem, and in the attachment...

G'day, I am here to seek advice on a textbook for my second-year undergraduate course in electromagnatic field theory. My concern with the recommended textbook is that it isn't easy to read. Any author that proceeds through a proof by simply stating "Next, taking the curl of..." doesn't offer...

Hello! So I need some textbook recommendations for calculus based physics course. I have taken an algebra/ trigonometry physics course last semester, but now I'm taking a calculus based. I have a textbook which the professor told us will follow our course. The book is Fundamentals of Physics...

I want a QM textbook which introduces detail knowledge of density matrix and trace (i.e. the average), who can recommend one for me? Thank you.

I am looking for a graduate level textbook that would sufficiently describe the two phase flow characteristics during flow boiling. What textbook could I use to explore this topic? Is a graduate level forced convection going to cover two phase flow?

This is my first time to be an instructor for a class and I have to prepare problem sets for my students. For that purpose, I collect problems from different textbooks. Unfortunately, if I cite the source of each problem, students always find the solution manual of this textbook online and...

Hi at all. According to you which of the two texts, between Landau-Lifshitz (mechanics) and the Goldberg (classical mech) is better for study Analytical Mech ? Or there are other better ones ?

Hi, I've just finished A Level Physics, and after a gap year I'm headed to do Physics at Exeter. I'm looking for a textbook or online course or something that has lots of A Level and (maybe slightly higher) Physics questions that I can work through over the course of this year. Does anyone have...

What are the most poorly worded sentences or oddest figures that you have come across in a textbook? It could be something in the general text or in the practice problems. Please cite the book if you can so others can find it!

Hi all, does anyone know if Bransden's book has a solutions manual out there somewhere? I would loathe to go through the chapters before realising that I can't find solutions to its exercises. If not, are there QM texts out there with a similar scope to this book that do have solutions manuals...

hi please refer to the inline image: What do the stars mean? I can't find a reference or definition elsewhere in my textbook...

This is excerpted from George E. Hay's "Vector and Tensor Analysis". The author gives the statement that the limit is equal to 1 without any explanation, perhaps because he thinks it does not belong to the contents of vector analysis. I can see it intuitively, but I want a rigorous mathematical...

Hello, I want to learn Physics, starting from mechanics to quantum mechanics and such. My brother is a physics student and he uses the University Physics text. This seems to be extremely popular- all my friends have also studied with this text. Is this a good book to get and start from page 1...
