I am trying to find some nice explanatory books about cosmological perturbation theory. I looked at Longair, Peacock, and Liddle. Even their level is nice, it seems to me that they are explaining things in a bit complicated way. Is there a nice textbook, articles, lecture notes that you guys...

This is a pretty technical question so before I post all the details, let me first ask if someone might be able to help. I am going over the book Grassmannian Geometry of Scattering Amplitudes and I am trying to calculate the anti MHV amplitude with five particles, at tree level (or...

I need suggestions on books and good lecture notes on calculus of variation. I've previously studied vector calculus and multivariable calculus.

OReilly published a new book, Programming Quantum Computers. From my brief scan of it, the book looks pretty comprehensive. They use circle notation for the Qubit states and have a simulator (QCengine) to go along with the examples on github. The programming language for their algorithm...

It's been 2 years since the SR book was released. Any news on when the GR book is going to be released?

Summary:: Need book suggestion for following syllabus. (Globally available hardcopy is preferred) I'm a civil engineer and need to study graduate level physics for an exam. I need suggestion for a book consisting basic to moderate depth of the topics below. I've comfortable with both, algebra...

As in constructions that consist of a membrane of some textile and are sustained by pressurized air bombs. A paragraph mentions that in the face of strong winds or snowfall the internal pressure rises... but i don´t understand exactly why is that. I´m just curious and would like to know. pd...

I recently read Cesar Hidalgo’s 2015 book: “Why Information Grows”, which I heard about recently on Sean Carroll’s podcast (I like it). It’s mostly an economics book that derives its main ideas from how information underlies organization in the universe, as well as in economic dynamics. I like...

Can anyone suggest me a Fluid Mechanics textbook? I am currently in High School in my Junior Year. I am looking for a entry-level textbook so I will be able to solve I.E. Irodov's Hydrodynamics section. (My Mathematics is quite strong)

The integral is called the line integral of ##F## from ##A## to ##B##. The work done in the displacement by the force is defined as, ##W(A\rightarrow B)=\int_A^B \vec{F}.dr## where the limits ##A## and ##B## stand for the positions ##r_A## and ##r_B##. We now return to the free particle...

I am planning to study 8 semesters worth of physics major (physics introduction until field theory, QED, particle physics, etc.) What are the recommended books for each subject? I am currently at Schaum's vector analysis, is it enough for the subject?

I'm currently looking at how fermion masses are produced via the Higgs mechanism in "An Introduction to Quantum Field Theory" by Peskin and Schroeder. It all makes a lot of sense and I've been fine with it so far, but I ended up getting stuck on something that's driving me nuts. I feel silly...

If anyone could help me understand how Peebles gets from line one of the autocorrelation to the second line, I'd be most grateful. I don't understand what identity or property is being used to go from a product in the expectation value to a sum in the expectation value.

I'm currently in my third year of medical physics and have problems when it comes down to reading. If I'm not taking notes of what I'm reading, I tend to lose attention and give up. The problem is that it takes A LOT of time to read and write, in my opinion. If we have about 10-15 pages of pure...

I'm excited to re-read both! Even has colored diagrams.

I started reading the book and I love it. In my opinion, even if you do not agree with the author's interpretation of quantum mechanics, it is a great read. Has anybody here tried reading it? The World According to Quantum Mechanics 2nd Edition by Ulrich MohrhoffHere are some abstracts.

Twice I found the following derivation of ##E\propto v^2## in a little distinct forms. https://www.physicsforums.com/threads/the-final-explanation-to-why-kinetic-energy-is-proportional-to-velocity-squared.78484/#post-609992 The derivation is in post #9, if it is not shown properly. This...

I am not a physics guy I'm just a husband trying to read in bed at night without disturbing my wife. Does infrared light reading glasses exist?Scientificly, can they be made?

Hi everyone, was just wondering what people think is a good undergraduate QM book is as opposed to Griffiths. I've read through it, and I have looked and many people say it is good for people who've never been exposed to QM before, but when it comes to solving problems I struggle a lot, and...

I'm looking for recommendations about advanced calculus books. I'm interested in going further and deeper than nth-order linear differential equations, but overall as a Physics student I'm deeply interested in being very, very comfortable dealing with line, surface and volume integration...

Hey, PF! I'm currently self-studying math and sometimes when I find the material too dry or technical it helps to have some outside literature to give me the motivation to continue on. I have Joy of X, Men of Mathematics, Mathematical Thought from Ancient to Modern Times, Zero, e: The Story of...

I'm reading the book "Why we sleep?" by Matthew Walker. If some other experts have any experience with this book could you tell me your opinion? Is our modern society really blind to very good known facts mentioned in this book? For example, a necessity to sleep at least eight hours every day...

I tried using coefficient of friction = friction / Normal force, but needed a value for friction. I then tried to find the friction using a = f/m, but was unsure of which value to plug in for force. Simply finding the force given a and m will not yield the correct answer; the net force must be a...

Continuing the summary, the author argues that if ##g## is nearly 1, i.e ##g(u)\approx 1+\epsilon(u)##, one obtains the solution: ##f(u)\approx 1-\epsilon(a)##. The derivative in the summary, i.e the dots represent derivatives with respect to ##u##. Then how to deduce the solution for ##f##? If...

Hi, I'm already familiar with differential forms and differential geometry ( I used multiple books on differential geometry and I love the dover book that is written by Guggenheimer. Also used one by an Ian Thorpe), and was wondering if anyone knew a good book on it's applications. Preferably...

Basically, it's a person's recitation of a law of nature during class in this work of fiction: "Golpalott's Third Law states that the antidote for a blended poison will be equal to more than the sum of the antidotes for each of the separate components." It baffles me because the person...

Hey all, My book says/does the following. Use the following equation for a plane wave Fill it in the klein-gordon equation To get Which results in Is this right? I got something different and no matter how hard I try I can't replicate the same answer. I've gotten the last equation, but...

Hi, I don't understand why the author in calculating the expression for the specific heat, divides by ##1/V## (the total volume). Also, in calculating the fraction of modes with frequency in the range ##v##, ##v+dv## he divides by ##V## (eq. 2.65, 2.67) Thanks, Ric

I am trying to learn group theory on my own from Schaum's Outline of Group Theory. I chose this book because there are a lot of exercises with solutions, but I have several problems with it. 1) In many cases the author just makes some handwavey statement and I have to spend hours or days trying...

in the book " transport phenomena" (Bird) when obtaining the famous equation of hagen poiseuille Bird defines a variable that involves the pressure, but when doing an exercise a term magically disappeared, someone could explain to me what happened why we took into account the pressure in this...

So, when you are holding a book by your hand, and not moving, you are using chemical energy(correct me if I am wrong), but neither does the potential energy increase, nor does the kinetic energy, so what happens to the chemical energy?

My professor will be using Huang's Statistical Mechanics next semester and I have been reading a lot of polarizing reviews. Does anyone recommend a book to read parallel to Huang's to better understand the material and that discusses the same topics in similar fashion?

I've been trying to understand the following very interesting problem: "Julius Ceasar was murdered on March 15 in the year 44 B.C. at the age of 55 approximately 2000 years ago. Is there some way we can use the laws of relativity to save his life? Let Caesar's death be the reference event...

Hi, I'm looking for books with a really good explanation on Galilean Transformations. I find the books and/or sections where only the theory of how to convert from one to another inertial system is mentioned, but nothing with concrete examples and additional exercises. Any suggestions are...

I am studying QFT from the book A First Book of QFT. I am currently in the chapter of QED. The authors have written down the interaction Lagrangian for QED. Thereafter, they have taken a special case of the electron, and written down the normal-ordered interaction Hamiltonian for this case...

I am not sure where does the dy term, phi^2 and phi^4 terms come from. I guess there are dx and dy because we have to account for the nearest neighbour pairs in the x and y axis? I guess there is a phi^2 term because 2q_a*q_b=(q_a-q_b)^2-q_a^2-q_b^2, the term q_a^2-q_b^2? How about the phi^4 term?
