Howdy all, Recently I have dabbled in homebrewing mead and it turned out... drinkable at best. I am making another batch soon and want to improve my methods. I am a nuclear engineering student, so naturally I feel that something as personal, liberating, and chemically miraculous as...

Does anyone know of any good resources online of where I can get clear and simple explanations on this subject? I don't want to read journal articles about this or want websites with heavy duty math since I don't have time to go through all of that right now in that kind of depth. I just want...

I'm a visual thinker and I use 3D images and animations in my head to think about scientific concepts. Learning is a thousand times easier when accurate, 3D representations are provided for me. I found these videos: http://www.cassiopeiaproject.com/videos2.php which are BRILLIANT! That quantum...

I've been looking for some good resources on integrals in four-space (SR and GR), and hope someone can suggest some! I'm not too interested in abstract mathematical formalisms to the extent of pure math though, I must keep in mind that this is all to do with physics (at least for me!). I know...

Hello everyone, I am currently taking an introductory course in linear algebra. I am beginning to struggle with concepts like nullity, bases, spans, etc, and my college book is not helping. These are concepts that are very abstract to me. Could you guys point out web resources or books that...

Have my first physics exam Thursday which I am told consists of 6 questions and one proof. I am curious on thoughts of what a proof on an exam may consist of, and it there is any pages or books I could reference to give me some basic proofs or ideas of what I may see on the exam and how to...

Hey Everyone, I am extremely glad to have found and joined the physicsforums community, and look forward to working and learning from others who share my enthusiasm. I'm currently enrolled in Precalculus, but find the class to be a little slow and really scripted towards teaching students the...

I would like to ask how to change the frequency of the ac supply (frequency = 50Hz) to a ac with a very high frequency. Does anyone suggest any materials or websites for me to reference? Thanks.

I was taking a lecture series this summer at my school where a professor was introducing us to introductory Galois theory. It was a very 'slack' introduction, without too much rigour. However, about a month in (only 3-4, 3 hr lectures) they stopped due to outstanding circumstances. I was a...

Hello, I'm interested in self-teaching over the summer in order to gain an advantage in the courses I will take next year. The subjects in question are: - Calculus 3 (multivariable) - Differential Equations - Linear Algebra - Thermodynamics - Strength of Materials I know that MIT...

More recent book than Nielsen and Chuang "Quantum Computation and Quantum Informaion" For this famous book, I discovered too late that there are no References more recent than 2000. Do you know of a textbook that covers more recent developments in Quantum Computing? Thanks Don Parsons

Hi I am thinking of learning french and/or russian. In the days of open source software, I am sure people have created great resources for this purpose. I am looking for such learning material. May be videos and stuff. Should have clear information on pronunciations. There is a lot of...

First off, I apologize if this is in the spot. I thought about this off and on since this morning on where to put it. There are probably four sections this could go. Feel free to move it if needed. I am awful at recognizing and solving taylor series and approximation type problems. Since...

Hi, I am just wondering if anyone knows of any website that offers raw statistical data. This may be a major request but the data also has to contain dummy (indicator) variables. Thanks

I'm currently in classical mechanics, and we're doing collisions and two body problems currently. A good portion of the material is covered only in the notes. I could use some supplementary materials. I've looked around on the internet but I haven't found any good resources yet. I was...

Most of the sites here aren't very helpful for learning astrophysics. However, they are amazingly useful for learning more about astronomy in general (and many cover far more than what you will find in any book or textbook) http://www.solstation.com/ - amazing amounts of detail for many stars...

Any resources to learn how to do proofs or view abstract math better in linear algebra? A lot of time when I read the solution to proof questions, I don't even see how that proves the statement. The way they are written seems unintuitive. This is my first abstract math course. I've never had...

I thought the sticky topic "resources for physics teachers" looks like a concise listing for reference, and not a place for asking a bunch of questions, so I thought I should ask my questions in a new topic. I'm teaching an algebra-based college class in electricity, magnetism, geometric...

Hi, I will be volunteering my time helping my professor in the realm of "electronic packaging." There doesn't seem to be a lot of straightforward tutorials on electronic packaging, could anyone guide me with the proper resources so I can take a look? Thanks Carlo

Hey guys I've been toying with the idea of building a diy digital annometer I'm hoping it can be achieved with a device which rotates in the wind which will generate pulses from a light interupted switch. The pulses will be sent to a microcontroller which will use the info to calculate...

Over the past 3 months I've been watching Leonard Susskind's lectures (Stanford) on quantum mechanics and particle physics from YouTube. This has been an enjoyable experience and I would like to further my own education. My interest is in semiconductor physics particularly modelling using the...

Hey all, Just like to prefix this question with the statement that I am a computer scientist with a strong interest and passion for physics, so please forgive me if this question is a tad naive. With that out of the way, I have a general question about this image: It's from "The Little...

Hello all, I am asking a question that I expect will return many answers. If any of you were presented with a individual who loved the study of the very basics of energy and matter, what would you tell that person to read? Books, videos, articles...what are the best to introduce...

Not sure this is the right section for this question, but it seems the closest so... I'm part of a small team that's working on designing a scifi space-based realtime strategy (RTS) game. One of the things that we'd like to incorporate into the game is relatively realistic Newtonian physics...

im trying to learn about electricity (especially DC circuits) and having a tough time, the textbook i am using 'fundamentals of physics' by halliday,resnick, and walker doesn't do a very good job of explaining. does anyone know of any good resources that could help?

Currently in my course in topology we have covered the point-set portion of the Munkres text, and the professor has moved into some additional material in which munkres has no resources, mainly the classification of surfaces. The professor let me borrow his resource for a while, but I was...

Hi PF members. I'm a first year engineering student, and recently got my midterms back and was highly disappointed with the statics mark, 55% compared to the class average of 23.8/40, SD 9.1. I did a very large amount of practice from Hibbeler's Statics textbook, 12e, but it seemed that the...

I teach an introductory maths course which includes function, algrbra, co-ordainate geometry, quadratic equations, limits, differentiationm trigonometry, exponentials, logartithms and complex numbers. Is there a way I can post these notes somewhere on this site for people to download?

Any Good Resources for Non-Technical, Non-"Popular" Physics Videos? I am a huge fan of Richard Feynman, because he would often give lectures which were not directed at a technical-mathematical audience yet which nonetheless didn't 'fake' elements or resort to goofy comparisons such as billiard...

Hi, I'm trying to learn some geometry. I'm a maths graduate but didn't take any differential geometry. I did take a GR course, and now want to learn the 'proper' geometry theory that underlies some of the ideas. Does anyone have any good resources (videos, or lecture notes) that they can...

I need to have information on plasma physics journals , articles , can anyone give me names of some useful sites which send mails on what happening in this field.
