A marvelous book from Academic Press covering current injection at metal and semiconductor interfaces, current flow, and space charge effects. Copies in good condition are selling online for $100 - $300. The dustcover is chipped but it has done its job to protect the cloth book covers. The...

Pages are in excellent condition, lettering on cover is faded, name and date purchased written inside front cover (20 Aug 1974). These books convinced me that I could make a telescope, but that it was a larger task than I really wanted to tackle. Make an offer, preferably enough to at least...

I am happy to announce my book A. Neumaier and D. Westra, Algebraic Quantum Physics, Vol. 1: Quantum mechanics via Lie algebras, de Gruyter, Berlin 2024. It features a mathematically rigorous but still physically lucid account of quantum mechanics from the point of view of symmetries...

I just wanted to know if this book has clear exposition, if it's any good and what are the prerequisites for it. Also, I don't think it's can be a primary resource so I just wanna know how good it really is in terms of supplementary material and just in general as a dover book. Also, I wanna...

There's a dover book called "Statistical Thermodynamics" by Erwin Schrödinger, I have worked through "Concepts in Thermal Physics" by Schroeder and I think Erwin's book blends some of thermodynamics with quantum mechanics so I don't think I'll be able to comprehend it, anyways I just wanted to...

This is page 73 of the book. As you can see, the mixed derivatives with the affine connections vanish in the second term. Why does that happen? This is used to prove that the connections are not a tensor, and i figured you could also reason it out even without making those terms vanish. OBS...

TL;DR Summary: The theory for ears are well developed so far. Is there a more authorative book or paper? Where can I find a good book or a paper?

TL;DR Summary: Hey everyone. I need help with clearing my concepts of mechanics. I am really confused. Are there any good books which can make me understand concepts in a better way? Book recommendations for mechanics (for improving basics).

I believe that ##f'(\Phi(z))=\frac{df(\Phi(z))}{dz}##, I get confused with the prime in ##z'## and is it really just this derivative? I wonder how many people read this 1983 book.

I have been interested in writing a book for a while and recently got to talk with a book agent to get some understanding of how publishing might work for me in my specific case. This has caused me to rethink some things. The book I want to write is about what it means to biology if you...

Can a visually impaired person understand the book Visual Complex Analysis by Needham? I mean, in principle, e.g., even being helped by somebody with no visual impairment. IOW, can its content be conveyed by pure text, without illustrations?

Has anyone here read this https://www.amazon.com/MANIAC-Benjamin-Labatut/dp/0593654471?tag=pfamazon01-20 It is a strange book, seemingly about Johnny von Neumann. Each chapter appears to be a short essay written by von Neumann's colleages and wives. Feynman, Morgenstern, ... As I read this I...

I’ve recently restored a Cossor 501 valve (tube) radio, which can receive LW, MW and SW. It has an external antenna socket (for SW), and I’d like to gain some knowledge on how to design and build something to plug in to it. A single wire about 20m long, draped out of the window, has enabled me...

Hi all! I've never been studied the identities and such of secant, cosecant and cotangent. Yet I think, it would be useful to have them in my toolbox. Thus I'm asking, if anyone would know a reasonable book or other kind of material (paper or pdf) about trigonometry that has brief theory...

I bought a copy of Adler's new book on relativity. Is there a misprint on page 16 regarding the Lorentz metric = diag (-1,-1,-1,-1) or am I missing something? The text itself after the equation suggests it is the same metric as on the earlier page so that index placement, two lower indices vs...

For this, From the work kinetic energy theorem, if we assume that the book and the earth is the system, and that the finial and inital speed of the system is zero, then is the work KE theorem there is no net work done on the system. However, clearly there is work done on the system is shown by...

Hi, I am trying to learn relativistic classical field theory as a preparation for studying quantum field theory. I am currently reading chapter 13 i Herbert Goldstein's Classical Mechanics edition 3, but I think that this book is a bit too brief and does not fully derive and explain the...

Hi, Are there calculus books that lie between Stewart (or Thomas) level and Spivak (Courant/Apostol) level? Thanks.

1.52cos(31)+Fbsin(Θb) = (0.305)(9.8) Fbsin(Θb) = 1.69 Now for horizontal direction: Fbcos(Θb) = FLsin(ΘL) cos(Θb) = FLsin(ΘL)/Fb cos(Θb) = (1.52 x sin31)/1.69 cosΘb=0.464 Θb = 62.35 I thought to find Fb I would just plug the Θb value into one of the trig functions, but apparently both of my...

There is a problem in my technological concept that does not allow the normal development of the plot of the book. It takes place on an ocean planet where being above sea level is absolutely dangerous with the level of technology that exists there. So all combat operations there take place...

TL;DR Summary: Physics book recommendation Hi everyone, I just found this site and I'm thankful for that. I want to study Physics as a pure science but in my city there is no bachelors degree, so I want to study by myself if it's possible. I just don't know where to start or what books should...

This problem is from MIT's module again. I have a doubt about Newton's Third Law. How is the normal and weight of the book not Newton's 3rd Law pairs? When the book is placed on the table, I imagine that the book's weight exerts a force on the table and the table exerts and equal and...

I'm looking for an undergraduate-level 'mathematical methods' or 'engineering mathematics' book that uses SI units for the purpose of self-study. I've had my eyes on Zill's Advanced Engineering Mathematics, but it seems to use US customary units. So ideally I'm looking for a book that covers...

When I solve the equation sometimes the answer in the answer keys is different but the same. Why do they do that? For example: After solving the equation I got 1/√2 which is the same as √2/2 because we multiplied it by √2/√2. Is there any good explanation why the book writer mathematicians like...

Summary: What would be a good book for learning Linear Algebra by myself in my situation (which is explained in my post below)? I did an undergraduate Linear Algebra course about 18 years ago. The textbook we used was Howard Anton’s “Elementary Linear Algebra”. The problem is that I never...

I did not know that September 18th to the 22nd has been "Banned Book Week" since 1982. It is interesting that a country that has such a devotion to and legally protects free speech should need such an event. It is also curious that a country that permits yellow journalism prominently sold in...

Hi wizards, I'm working through Jackson's book on E&M (3rd edition) and got stuck in section 3.12 on expansions of Green functions. I have three questions regarding section 3.12: First, why is Jackson trying to find a Green function that satisfies equation 3.156? To my beginner mind, it...
