I'm looking for a text that covers group theory and its applications for QM and QFT, targeted towards an audience that knows their QM but is ignorant of everything quantum fieldy. Any recommendations?

I'm working on a project to be exhibited early next year and I'm seeking some advice on one particular element. The project explores the kinesthetic properties of sound, and the ability to transform an aural experience into a kinesthetic one. A custom music track will play in the room...

I am teaching a basic mathematics class, and am using Punnett squares as an example. In order to keep the students' interest, I am looking for examples of human traits, no Mendel's peas and so forth are not what I need. I wish to keep to monohybrids, as dihybrid hyprids would be too confusing...

Calling math history geeks -- any reading suggestions? Hey everyone! Inquiring minds (well, at least one) want to know: what are some good books on math from a historical perspective? I recently acquired "Mathematics of Nonmathematicians" (Dover Books) as the reviews suggested it was mostly...

I am a senior physics major, and over Christmas break, I have to take a comprehensive exam that determines whether or not i graduate. The topics I am worried about are E&M and Classical Mechanics. The other things are closer to intro level classes. I was hoping someone might have some good...

Hey, I was wondering if you guys could offer any course guidance on independent studies I could try to take my senior year. I have some ideas, but I was wondering whether you guys could give me any recommendations/book recommendations. My background: I initially wanted to go into a more...

Can you suggest any source available on internet which may be particularly helpful for those studying/brushing up knowledge of classical or quantum field theory without help of any teacher or friend? Some calculations are at first not so straightforward and there are many types of calculations...

My group project over the next year will be on diffraction, so as part of our project plan my group needs to decide what experiments we'd like to do. I know the bare essentials of what diffraction is, but not in much depth (I'm trying to rectify this!) and was hoping for some suggestions for...

Hello guys. Since this is my first post and I can't post in Pre-calculus Learning Material, I shall post it here.Now, to the topic. I am passionate about learning maths, however, because I live in Australia and go to public school, the level of maths that they teach is miserable (Year 9...

Funny story, or maybe I'm just dumb and don't understand why my professor is being all petulant about this. ∫∫h(x,y)dA If z = h(x,y) and h(x,y) = f(x)g(y) ∫∫f(x)g(y)dxdy = ∫f(x)dx∫g(y)dy I did this on my own while working through some double integral hw. Seems obvious, and the...

Hello, I am currently a Chemistry major, and I am really good with sciences. My problem is with math ( Calculus), in fact I always had trouble with mathematics. The problem with my situation, is that I am really interested in Math Application, in addition I really need it for my major. So I...

Hello, I'm new to the forum. Does anyone have any suggestions for doing well on Fluid Mechanics? I got a 34 on my previous test (class average was a 35..). Any help would be appreciated. Ideally, I would love to find something like mech movies for mechanics of materials. My biggest...

Hi, I am looking to build some very simple state machines, with JK flip flops. I am planning to run them off a 9 volt battery, if that is feasible. Does anyone have a suggestion on what JK flip flop to buy, preferably from Mouser? I know Mouser has about 300 different parameters to pick...

Hey guys, (this is not homework). I am working on a "out of class" project right now, and I want to get some ideas on ways you can run an experiment in which you can apply quantum theory to biology? Thanks :)

I am not currently taking a Geometry class, but I've always been interested in Geometry and I'm now looking for a good College-Level Geometry book.

Hello All, I am new to the field of "Control of Quantum Systems". However the things that I know are: Controlling quantum mechanical systems is a challenging job because if want closed loop (feedback) control and measure the systems's output, the output itself changes (because in quantum...

It seems that being an academic requires you to be able to come up with interesting and unique ideas for attacking interesting problems, and I simply don't think that's a skill I possess. But I'll soon have a math Ph.D. in mathematical physics (and a physics masters' degree) from a large state...

Homework Statement Hi guys! Our finals are coming up and our Physics professor is asking us to create a project which is equivalent to our final quiz and if selected by the Department head we would get a 100% in our subject for the term. Our professor specified that it has to be a simple...

Hi, I'm looking for some additional reading material while preparing for an E&M course. I'm going through Jackson and Griffiths, and I'd like to read a few scientific papers that will be good "E&M exercises." Anybody have papers in mind? Any suggestions for an intro to plasma containment?

So this fall I will be TAing for the first time for, most likely, general chemistry but possibly physical chemistry. Frankly, I don't know what to expect at all. What does one do when students don't have questions? What does one do if students don't want to participate? If the professor...

I am biomedical enginerring student, I am working to gather Ideas for my graduation project and I will appreciate if anyone provides me with some ideas and some relaible sources (if any) for any innovative biomedical engineering project

I'm taking Statistical Mechanics this semester. I already took Thermodynamics, covering the first three laws (0,1,2) at the level of Fermi's Thermodynamics book (and other similar ones). My Stat. Mech. teacher is a condensed matter experimentalist and he's boss at what he does, no question about...

Hi all - couldn't find another suitable place to post this on the Internet... My TI92 died last week after 15 years of use (OK I killed it with coffee), and I thought I'd just try and get by with Wolfram Alpha but it's just clunky and horrible. I'm currently using my spare TI86 which lacks a...

Hey guys this is my first post, glad to have found this awesome forum. As the title suggests I want to improve my math skills and I'd highly appreciate if some of you could recommend me some books and in general tell me which areas I should focus on. I feel that my current math skills are...

Does anyone have a lab bench function generator that they really like? I'm going to be buying one, and was curious if anyone had any opinions on which one is nice or if they bought one and thought it was a piece of junk. I don't really care about specs, more just which ones you prefer to use.

Hi I'm white knight(night) and I'm from california. I noticed you didn't have a new member intro section, nor an off topic section so I'm posting here. I signed up on your forum because, well to be frank, i had a bad trip on some drugs about a year ago and had a psychotic breakdown/shift in...

So I have decided what I am going to do (for now...this will probably change 500 times throughout the course of my life. I'll take a tentative plan over no plan for now). For the next year I will save up some money, and keep learning economics/finance/weight training. After that I want to go...

I am designing my own Charpy impact testing machine and I am unsure what would be the best as well as relatively simple and affordable method I can use to accurately measure the angle the pendulum travels after it has broke the sample. I would also appreciate any complex and more expensive ideas...

Last time I made the mistake of making a solutions manual thread. This is probably what I should've asked instead: Most textbooks I own either have poor student solutions manuals or offer a few answers in the back, which makes learning yourself and checking your work rather difficult. I'm going...

So my girlfriend and I are moving to Boston in August so I can attend grad school there. But neither of us have moved to another town before, so we don't really know how the logistics work. I'm looking for any tips or tricks or things to watch out for about the actual mechanics of moving to and...

Exactly what the title says. The prompt is this: Chose an actual example of scientific explanation, and use it to evaluate Hempel's and Ruben's accounts of explanation. I am not understanding the second part, how I am supposed to use an example to evaluate Hempel's and Ruben's accounts of...

I was wondering: What textbooks have everyone found useful in prepping for the subject GRE? Are there any textbooks particularly helpful in prepping for the subject GRE and if so, which chapters of the texts should be gone through when prepping for the exam? I was thinking of using Stewart to...

Hi, Let Z be a r.v. from N(0, σ^2) and let Y = Z^2*exp(Z)/(1 + exp(Z))^2. What is the exptected value of Y, E(Y)? The delta method (Taylor expansion) doesn't work since the errors seem to accumulate. Any suggestions? This is a non-standard problem related to my research and I am totally stuck...

I am a NYC resident but I'd really like to attend UC Irvine because one of my best friends who is a grad student (in a top five school, nonetheless) referred me to a specific professor with whom if I play my cards right and do good research work with, can network me with very good experiences in...

Hello everyone, I am trying to model the process of laser ablation on a material using MATLAB. The governing equation is of the form: ∂T(x,t)/∂t = ∂/∂x(A*∂T/∂x) + B*exp(-C*t2)*exp(-D*x) with one Initial condition and two boundary conditions. Using the built-in 'pdepe' function in Matlab...

As I can see from the formula of cauchy inequality: (a1^2+a2^2+...+an^2)^1/2 . (b1^2+b2^2+...+bn)^1/2 >= a1b1+a2b2 + ... + anbn Can I conclude from the above formula that: (a1+a2+...+an)^1/2 . (b1+b2+...+bn)^1/2 >= (a1b1)^1/2 + (a2b2)^1/2 +...+ (anbn)^1/2 by setting a1,...,an =...

Hello I have to say I am a mathematics fanatic but my frustration stems from the fact that I teach myself mathematics meaning that I am basically lost what to do when I am impeded by an obstacle. To cut a long story short, I have knowledge in calculus, complex analysis, linear algebra etc and...

Hello community. I am currently working on a product that requires relatively high torque and rpm, around 3 N/m torque and between 150-300 rpm to be specific. My knowledge about motor is very limited and i am running out of time. I understand that i won't find the exact spec and probably will...
