are there more advanced forums than this for astronomy/cosmology? I asked a few questions without reply on here so I guess I need higher level forum.

I am an electrical engineer 20 years from my last formal course in grad school. I wish to teach myself advanced optics, particularly diffraction theory, analysis of polarization using Jones calculus, aberrations, etc. I realize that my mathematics chops are sadly rusty through years of disuse...

I'm about to start my first year of studying mathematics. My university requires me to take quite a lot of basic courses in the first year and after that there are some strict limits on the number of courses I can take. This means that I will not be able to take all the courses I would like to...

Looking for an Advanced "How Things Work" book Hey, I was just wondering if anyone knew of a book that was like a "How things work" book but written for someone who has a bachelors in the physical sciences, engineering of applied math or some such? I'd settle for a website. Like what I'm...

There are several reactions that one can have upon seeing the text Advanced Calculus by Sternberg and Loomis. (Those unfamiliar with this book can find it online here: http://www.math.harvard.edu/~shlomo/) My reaction was simply to be surprised at the extreme discrepancy between the material...

Is there any resource in the net about advanced math for nuclear engineering? regards

Hi all, I'm a bit new here. I was unsure where to post this but this seems most appropriate to me. Getting down to it, I'm interested in a number of topics in advanced physics. Specifically, I'd like to begin to do a bit of self-guided study on special/general relativity and eventually QM and...

This is a bit different kind of help that I need compared to most other threads in this forum. I was not sure of where exactly to post this. But, since it is pretty much homework, and it's for my AP Calculus AB course, I thought this would be an appropriate place to put this thread. If not...

Hi all. I need a book on advanced numerical methods (note: methods, not analysis) suitable for an undergrad. I have already had a first course in numerical methods, the usual one an undergrad takes. The topics the book needs to cover is: Finite difference, finite elements and spectral...

I am a rising sophomore and am currently registered for Physics I (calc) and Calculus II. However, I am attempting a double major (phys, math), and have started late...so I would like to double up on my maths for the next 2-3 semesters. I am currently learning Calculus II, so when I take the...

Hi everyone, In my advanced quantum course (I'm a master's student) I'm supposed to give a 40 minute talk about something that I find interesting that is related to our course material (which is basically anything in quantum. We basically covered: scattering theory, many-body stuff...

Hi, I'm looking for good textbooks or problem books for a 9 and 10th grade students. Maybe not as difficult as the AMC or IMO level math, but some problems that require some thought rather than just plug and chug formulas. For example, I want to find a good problem set for trig proofs, and...

capacitor problem! (Advanced) Homework Statement I am simulating a Biological system. For ease just consider it as a parallel plate capacitor. Now the simulation software takes the value of charge Q, but not the value of V. Now as C=Q/V, can we say that the charge Q of a parallel plate...

Hello all, I usually consider myself to be quite good at most things math and physics related, but compared to some of the people here, I'm sure I'm very terrible at it. I have a very advanced projectile motion problem that I need to solve (not for school). I'm trying to contact everyone...

I somehow managed to get Bs in two calculus courses and was pretty confident that in a pinch I was capable of doing work involving lagrange multipliers, Green's theorem, convergences of improper integrals, and such. My textbook was multivariable calculus by Larson and Edwards which I was sold...

For example what is the difference between an intro mechanics or E&M course and an intermediate level one? What about an advanced one that you would take in grad school?

Questions: Where can I obtain the most advanced published papers regarding valid unification theories? If there are none, which published papers will get me closest when combined in their respective categories? Comment: It is obvious to me through speculation, physical laws have yet to...

I'm planning on taking a 3-year Advanced Diploma in a college for Electromechanical Engineering Technology. If I do well in this program, then I will transfer to an undergraduate engineering program at some university. I've been thinking, if the Technology program is equivalent to just some...

Hello, I am not a physician but I am a new Ph.D. student in computer vision. Despite this, I often get the feeling that the mathematics involved in computer vision or computer graphics is somehow similar to the one used by physicians, though this is not always true. Few examples are vector...

OK. I'm scared... this is the book I just got that one of my classes is using, and, reading the reviews on amazon ... well, you be the judge. I've never seen so many 1 star reviews for a textbook: https://www.amazon.com/dp/0534399002/?tag=pfamazon01-20 Has anyone used it? (this is the...

I am having problems understanding this. Could someone explain how to arrive at the answer for this problem . (-5/2)(x)(x+3)^(-3/2) + (5)(x+3)^(-1/2) Thank you It says to factor and simplify. Express the answer as a fraction without negative exponents.This is where I get to...

I was wondering if someone could just tell me whether or not Most of intro and all of advanced Physics is primarily built upon Calculus and any other advanced Math topics. I know that high school physics usually teaches physics from a non-calculus point of view but I am specifically referring to...

I wish to know whether there are free softwares available for doing calculations in quantum mechanics, special and general theory of relativity, quantum field theory and similar fields. Are there any computer related experiments for theoretical physics?

I was wondering what the difference was between textbooks or books that teach Algebra at different levels (elementary, intermediate etc.) and College Algebra. Do College Algebra textbooks cover all levels of algebra and more, or is this some advanced new algebra. P.S. Not referring to linear...

Hi, I will be teaching myself advanced mechanics over the next few weeks. Is it better to start with a modern book using all the new mathematics (manifolds etc.) or with an older one like Goldstein or Landau first?
