tl;dr version: EE senior, wants to take grad course next semester, is there a standard way to do this? Detailed version: I'm an Electrical Engineering major at a state university, and just obtained senior standing. For next semester, I'm interested in taking the graduate version of a class...

I'm aware that a lot of careers may only use one or two upper-level subjects that I study in an Engineering program, which is what I'm essentially in (Applied Physics Bachelor's with a co-terminal Master's in Mechanical Engineering). I doubt that there are any jobs out there that will use a...

Ok! Here is the deal. In one of my earlier threads I had discussed that I was a high school dropout and a lousy student at that. After several years decided to get back in school. Got my GED...enrolled in a community college. I have been there for almost a year now. Will graduate with an...

Hi, I'm having trouble understanding the concept of equivalence classes and would like some help on what it means to describe an equivalence class. Here is an example that I have deemed to be an equivalence relation but I have no idea about how I can descrive its equivalence class

Suppose I write the following in my stylesheet .class1 { position: relative; } .class2 { position: absolute; bottom: 0px; } and then the following in my body <div class="class1 class2"> </div> Will that div take...

Hi, I'm a physics undergrad at a pretty large university in the US. I would specify what year I am; but due to some recent complications in my life and the frustrating cyclical schedule of classes my school uses, (I think it's designed to work mainly for full time students who come in as...

Taking "Fluff" Classes This is something I've noticed about college education in general which really irks me. I'm a pretty good student. Physics and mathematics major, 4.0 GPA, research, scholarships, blah blah blah. In order to avoid having to take difficult physics/math classes at the...

Homework Statement If you follow this link http://www.math.tamu.edu/~ciken/teaching/spring2014/math302/practice%20midterm%202.pdf There are several optional problems that have been posted for studying for my exam. I figured it would be easier to read the original than have me try to retype...

I'm currently a freshman who is double majoring in Math and Mechanical Engineering. I took a class over the summer, and the instructor got me very interested in math again, which is why I added the second major. In high school, I was an average student (As in Bs) and As in Bs in all of my Math...

Homework Statement While reading through my textbook on abstract algebra while studying for a test, I ran across the following statement: There are two isomorphism classes of groups of order 21: the class of ##C_{21}##, and the class of a group ##G## generated by two elements ##x## and...

I'm just looking for the right words to use to talk about something like the "bijective correspondence" between the class of groups defined as pairs and the class of groups defined as 4-tuples. I'm talking about the "map" ##(G,\star,i,e)\mapsto (G,\star)##. It seems to me that it shouldn't be...

Hello, I am a transfer student that has been admitted to CSU Long Beach in the Fall '14 for a BS in electrical engineering and I would also like to pursue a BA in physics. I reckon this will take me 4 years. A BA in physics consist of taking lower division CALC I/II/III and PHYS ABC. Also...

I'm not sure if this is off-topic for this section of the forum but I wasn't sure where else to post it. I'm substantially behind compared to other physics majors at the moment (3rd year student with enough credits to be considered mid 4th year student) so i wanted to pick up the pace. I like...

I'm an undergraduate Physics major. By next semester I'll be three classes away from a Computer Science minor. I've taken a few programming classes and really enjoyed them(java and C#), so I will most likely be going the theoretical/computational route for grad school. I've selected some...

First off I want to apologize if there is a topic about this type of thing already that I missed. I went back through the last 5 pages and didn't see anything that seemed to fit it and am unsure of what I would need to search for to look through that function. Past that, I am a Mathematics...

I am currently in my third year of a physics and mathematics double major. I've taken almost enough mathematics to fulfill the mathematics degree requirements. I plan on becoming a theoretical physicist and attending graduate school. I've listed the courses I've done, and registered for, and...

Homework Statement ##e = \begin{bmatrix} 1 & 0 \\[0.3em] 0 & 1 \\[0.3em] \end{bmatrix}##, ##a =\frac{1}{2} \begin{bmatrix} 1 & -\sqrt{3} \\[0.3em] -\sqrt{3} & -1 \\[0.3em] \end{bmatrix}##. ##b...

Also sorry if you feel this is in the wrong place. I was unsure where to put it. I was wondering what the main differences in content/way problems are solved in Mechanical Engineering Thermodynamics, Chemical Engineering Thermodynamics, Thermodynamics of Materials ( for MSE), Thermal Physics...

Hello all! I would like to transfer from a community college to a university with an A.A. in physics. With this term ending, I am looking at the rest of the classes I need for my A.A. The science and math related courses I took this term was Calculus 1 and Introduction to Chemistry. Next...

So I'm in my final year of high school and there's this girl I think is cute and would like to get to know. However we have no classes together and I've only ever had one class with her back in grade 10. I see her in the halls and the cafeteria, she usually sits at a table near mine. I'm not...

I'm a physics major and it looks like my next classes will be a 300-level mechanics class and 300-level E&M class next fall. The problem is, I'm at CC right now and I took all the "tough" classes last year (calculusII,III, University Physics, Diffy Q) and I just have programming and biology this...

I try extremely hard in my math classes, and I do decently in them, but I would really like to do better. I got a B in calc I, B+ in calc II and III, and a B in discrete math, and at this point it's looking like I will get a B or B- (or maybe even a C+) in linear algebra. I always do a lot...

Homework Statement Let G be a group such that |G|>6. Then there are at least 4 conjugacy classes in GHomework Equations The Attempt at a Solution Well, I tried by contradiction by using the group of order 7, which must be isomorphic to the cyclic group of order 7, which has 7 conjugacy classes...

Hey guys, so I'm just some teenager who is in first year Mathematics and Physics Bsc at University of Strathclyde in Glasgow UK. I am doing really well since it's first year it is so easy... I had a dream yesterday, where I designed some arbitrary piece of tech, and then after that I got...

Homework Statement Determine the conjugacy classes for A4, the set of even permutations of S4. The Attempt at a Solution I'm trying to figure out a correct way that doesn't involve much straight up computation. Here is my thinking; Elements being conjugate in A4 mean they are conjugate in...

Homework Statement Hi guys, The title pretty much says it. I need to explain why: (a) an abelian group of order |G| has precisely |G| conjugacy classes, and (b) why the irreducible representations of abelian groups are one-dimensional. Also in my description below, if I make any mathematical...

I have an absolute love for chemistry particleurly analytical and organic. my problem is I'm not the greatest when it comes to math as i never was granted the opertunity for higher level math classes in grad school. I'm the first in my family to actually graduate high school. I tested into math...

Resident number theorist and global moderator at MMF (Charles R Greathouse IV) has graciously given me permission to reproduce an image he created to demonstrate the different classes of numbers: Rings are depicted in a ring, fields in an octagon, and algebraically closed fields in a...

I'm starting on physics I (introductory classical mechanics) and although I love the theory class, I find the lab extremely tedious and tiresome. I'm just two experiments since starting (we've seen grafication and measurement uncertainty) and they are quite disencouraging, specially after...

So my advisor is out of the country and I have to pick classes tomorrow, so I'm asking you guy's opinion. I'm a first year grad student and I've got 3 classes on my mind. I'm definitely taking graduate QM, but I'm trying to decide between stat mech and "grad level" electronics. I'm going to...

Good morning, I am currently a Senior in Computer Engineering over the summer i took 4 classes one of them were algorithm the teacher was not that great and failed half of the class (including my self), i didnt study as much as i could for the class so i kinda deserved failing, So at the moment...

does anyone find classes boring that aren't related to math and physics. like right now I am taking psych and it seems like I can't focus when I study like I can with math or physics. right now I have an 86. and I want to at least maintain a 4.0 my first 2 years of college. for when I get some...

I am looking for any ideas to do for demos or fun physics demos to do with kids for a summer camp. I need ten lessons in total and I would like to involve the kids with activities as much as possible. kids are from about 6 to 14 and classes are 30 to 45 mins and i get two 1.5 hr demos. Some...

I'm a physics major currently doing an REU in seismology, and I'm really enjoying it. I think I've finally found the field I'd like to pursue in grad school :approve:. I'm definitely planning on going for a geo science minor, but I'm wondering which classes would be useful to me going to grad...

Hey everyone, I've been trying to get a rough idea of what types of classes I should be taking for my upper level undergrad courses, and get an early idea of what type of graduate elective courses I should be taking. I'm a double major in physics and math, and plan to go to grad school for...

I'm working on my bachelors in Electrical Engineering and for Fall Semester I'll be taking first semester circuits, linear algebra, and third semester university physics. Can someone recommend another class that would benefit me in electrical engineering. These are the classes I'm looking at...

Homework Statement Let A be the set, A = {0, 1, 2, 3}. Consider the relation R on A give by xRy iff there exists k \in \mathbb{Z} such that x - y = 3k. Describe the equivalence classes of R. Homework Equations The Attempt at a Solution E_x = \{y \in A: y - x = 3k, k \in...

I'm going to university next year and I'm strongly considering doing physics. however the I'm slightly concerned because the physics degree at the uni I am going to has very little of the math that i thought is needed for physics. to illustrate my point, in the course there are no PDEs, diff...

Homework Statement Consider the relation on \mathbb{N} given by aRb if there exists k \in \mathbb{Z} such that a/b = 2k. Give an example of two different equivalence classes (that is, find x, y \in \mathbb{N} such that Ex \neq Ey, where Ex and Ey are the equivalence classes of x and...

Homework Statement We are supposed to prove that the addition and multiplication of congruence classes for integers are associative, commutative, and distributive. Homework Equations None The Attempt at a Solution To me, it seems like this would just be trivial as all these...

Hello folks, I was wondering if anybody could give me some suggestions on which mathematics courses will be of the most use for theoretical physics. I am a sophomore at Wayne State university and am taking intro to quantum mechanics and a first course in optics this semester. I am taking...

I'm trying to decide between 2 courses, Electrical and Electronic Engineering or Software and Electronic Engineering. I haven't got the complete class lists for both to compare but going by the bits I've got and the descriptions, the software and electronics course is basically the same as...

The problem asks to show that if the space Y is path connected, then [I,Y], the set of homotopy classes of maps I into Y where I = [0,1], consists of a single element. What I tried to do is take two arbitrary continuous maps f,g: I -> Y and show that they are homotopic. For each s ε I, f(s) and...

I have my first real lab class this semester (intro to circuits), and I'm kind of nervous. In high school chemistry I always felt like a burden in lab class; I could do fine on the tests, but in lab I always felt behind. By the time I thought to do something my teammates were usually already...

Its premature, but I definitely feel more aligned with theoretical physics over experimental. With that said, would math or computer science electives serve me better? I can choose 2 courses. Thanks!

I'm a chemistry major, but when I entered uni 3 years ago I was actually a performance arts major. Needless to say, at the time I was quite terrified of all math and science, and it took a bit of easing into; but I had copped out with easier math series and easier physics series. I'm...

This is a direct spinoff to the thread I started about which class general relativity is offered in. That question was answered and now I would like to align my math classes to prepare for tensor calculus. Here are the classes I am thinking of taking Linear Algebra Abstract Algebra I and...

I'm a sophomore studying physics and have been doing some academic planning over the break. I'm beginning to realize just how much open space I am going to have in my schedule. My scholarship requires me to take a minimum number of credits each semester, so only taking a few classes isn't an...

I'll be applying for graduate programs in physics and chemical physics in about 2 years, and I want to do research in statistical mechanics, particularly thermodynamics of fluids, non-equilibrium thermodynamics, fluid dynamics, nonlinear dynamics, and other fields related to this. I have time...

Show that if R1 and R2 are equivalence relations on a set X, then R1 is a subset of R2 iff every R2-class is the union of R1 classes. Attempt: I don't understand that if R2 has elements nothing to do with the elements of R1, how can an R2 class be a union of those elements belonging to an R1...
