Hi all, my university is offering a graduate level math course in integral equations for the following semester. I'm not at all familiar with them (I'm assuming they're the opposite of differential equations?), and I'm wondering if you guys think they are at all useful in the field of physics...

Hey fellow forum members, I just thought it would be interesting to hear what course you found to be most useful in your current day-to day role (occupation). It can be any course that you've taken at high school, undergraduate level, graduate level, or courses offered on coursera. Thanks

I've decided to learn programming in my holidays. And I've enrolled myself in a C programming class (Apparently they don't allow C++ unless you know C). The course requirement says familiarity with "programming techniques" I tried searching it but I din't get the meaning I just got various...

Hi. I have taken Cal 1-2 and am now wrapping up Cal 3 this Spring semester. My university offers a Cal 4 course during a 4 week summer term. This past summer, I took Calculus 1 during the summer, after a couple years break from mathematics (I'm a natural resources graduate student), and...

I am currently first year at university studying software and electronic engineering. It is okay... but it isn't very interesting. I find physics much more interesting so I've been thinking about changing to it. I would really appreciate it if someone could answer these questions, 1 - Is...

I took CS 1 (simple Java stuff) on the first semester, and that was relatively easy for me to do. However, I am not doing so well in my CS2 course, as I just miserably failed one exam to the point of likely losing hope of getting a B on that course. Now, I am a physics and math major, and I am...

Well from what I understand when a student transfers from community college to a university they start with a fresh GPA. Its kind of worrying me that by the time I transfer I will have all of my general eds out of the way and will have only engineering courses every semester till graduation. I...

I recently decided to start taking Physics two, it has been about 2 years since I took physics one and I am realizing as I am going through the material that I have seemed to have forgotten a lot of material I learned. I was successful in Physics 1 but I am concerned about this course. So far I...

I just started number theory, and I feel completely lost. I never did proofs in calc. I am used to watching the professor do examples, then with solutions manual at home see how the problems are done and use the manual if I get stuck. This book on NT has no homework problems or solutions. I just...

Hi, I decided to learn about relativity with this book, and I'm looking for people who would like to read it with me and discuss :thumbs:. Since I'm a little busy at the moment the pace will be quite slow, let's say about a chapter each two weeks (or more later for more advanced chapters)...

Hi, I'm a sophomore undergrad and recently I've been wondering how much weight grad schools in the sciences actually put into your "course load." I've read some conflicting views on the internet, books on grad school admissions, and faculty. The websites for some grad/professional schools list...
