Can anyone explain/give a good reference for Stiefel-Whitney homology classes?

Hello, I am trying to brush up on some mathematics and realized that I have to start from the very bottom. I keep getting confused by the symbols and it has been an ardeous last few days! Anyway, going through some stuff on set theory and came across the concept of equivalance classes. Let...

C++ -- Nested Classes A post or two I have been working with appeared to be associated with students in a C computer language programming course. In other words, the class may have not been object oriented. Also, mentioned in one post was the concept of housekeeping being less important than...

Hi, I'm a high school senior that's just been admitted to Caltech. They sent me their course catalog in the mail, and I've been looking over it this week. I want to major in physics, and someday study elementary particles, gravitation, and string theory. What math should I take? Caltech...

So, I've decied to major in Computer Science w/ a minor in Mathematical Sciences; however, I'm in a dilemma. I need to choose 3 more classes (out of the list below; I've already chosen the other 4 classes) and I'm not sure which ones I should take to make myself more "marketable" and a better...

Somebody told me recently that taking too many class looks bad because "it seems" that taking fewer classes shows that the student is concentrating more in depth. I want to take 5 this coming semester. I naturally would think that this is helping me become more qualified (taking a harder...

I am signed up to be a ME major at the University of Kentucky but I've always loved physics, especially quantum physics. Am I going to be able to take some advanced physics classes without majoring in physics? I know there is a lot of physics in ME but not the kind I want to take. Is a double...

so here's the thing, i basically have a physics minor and decided to go to applied math grad school since i think it'll open up more options and involves more math and won't involve experiments than engineering. i don't want to do theoretical physics since I'm concerned about job opportunities...

I have never taken calculus or physics, but for my major I require both. I am wondering if it is reasonable to take calculus I and physics with calculus I at the same time. Thank you.

In C++ what is the difference between an object and a class? I'm confused, is an object always a class?

Hi, I am currently attending a community college, but I will transferring next fall. One of the universities I am looking at offers calc 1,2,3&4 as well as advanced calculus of one variable and advanced calculus of several variables both of which have calc 4 and linear algebra as...

Hi guys, I am a sophomore in college right now intending to major in physics. The thing though is that I am fairly certain that I want to go to medical school and thus am just pursuing the major for my own intellectual curiosity. I am taking junior level mechanics and electrodynamics courses...

Homework Statement There's this one exam problem that I cannot solve... Here it goes: Consider the set Z x Z+. Let R be the relation defined by the following: for (a,b) and (c,d) in ZxZ+, (a,b) R (c,d) if and only if ad = bc, where ab is the product of the two numbers a and b. a) Prove that...

i'm almost done with my pure math major. i'll likely go to grad school to get phD, but I'm very concerned with job opportunities should i later decide i want to go into industry rather than academia. I've already completed the physics minor, but i doubt having a physics background helps that...

What is the mix of men and women in your physics classes at uni? I am right to expect a sausage-fest?

Hey everybody. I hope I posted this in the right section; it was either here or in Diff. Equations.. Anyway, here's the deal: I'm currently a sophomore at a community college, planning to transfer to a University in Fall of 2009 to finish my BS. By the end of next semester (Spring '08), I...

i'm about to enter my 3rd year, and i have been planning for a physics major during my entire college career, until recently, where i have decided to pursue pure math instead. i may decide to switch back to physics, or pursue mathematical physics, however i plan to take for sure this...

The stupid question of the day: The existence of proper classes is often proven by contradiction: assume that some object is a set, you'll find a contradiction, therefore it is not a set. We baptized those as "classes". Will (can) this even happen to classes? To find some object, assume it...

EMIII (EM waves in particular) REAL ANALYSIS II ABSTRACT ALGEBRA TOPOLOGY CLASSICAL MECHANICS (via Herstein) ... is this possible in a semester?

For my undergraduate mathematics program the required classes are Calculus 1,2,3, Linear Algebra, Differential Equations, Introduction to Advanced Mathematics, Advanced Calculus, Algebraic Structures, and Mathematical Statistics I. Then I am told to choose 3 classes from each of the lists below...

Ok, I plan on changing my schedule so that I can get some work time in. I'm thinking of taking 2 Junior level and 1 Senior level math classes back to back. Abstract Algebra, Differential Equations, and Advanced Linear Algebra. Anyone have personal experience? I'm in pretty good shape...

I am an undergrad student studying chemistry and I was wondering from the pros what classes you thought were the most interesting or helpful after school.

I'm asking because I'm going to be a senior next year and I really, really don't want to take AP Literature. I loathe English with every fiber of my being. I'm also taking German IV which I've heard is mainly going to be a writing/literature class and I don't think I can handle two similar...

Passing the AP Physics C Tests usually gives credit at college for a similar class. However, I was wondering, if I'm majoring in Physics and did pass the AP Physics C Tests, should I skip the classes in college and move on? Or would it be better to take the classes at a college anyway in order...

When I was in high school I took 7 classes in a typical semester and each class met 50 minutes per day 5 days a week. We were punished rather harshly for tardiness and classes never dismissed early. Since college is supposedly the next step of the academic ladder, it would seem natural that...

Here are two very similar questions about polynomials that I feel may have deeper roots (excuse pun). a) Does anyone know of any interesting theory related to them that I could read up upon? b) How would one start solving them? Here are the problems: 1) Show that there are...

Need help with Summer/Fall classes :( WOW ... UH has the worst schedule system ever! Ok, so I'm transferring to a University this year. I would really love to get advice on what courses to take. Background: I started studying Mathematics around 2 years ago at the age of 21, so I didnt grow...

A. Psychology B. Literature and Arts C. Journalism (Newspaper) tell me from your perspective which is most beneficial? but of the three, which two are best?

Prove that if [i] and [j] are equivalence classes modulo 1. Prove that if [i] and [j] are equivalence classes modulo n such that [i]=[j], then gcd(i,n)=gcd(j,n) 2. Prove that if gcd(a,b)=1 and if c divides b, then gcd(a,c)=1. please help

Hi, I'm considering the following classes: PHY 126, which is Physics B, and it meets 6 times a week (3x LEC, 3x LAB). MAT 211, which is Intro to Linear Algebra, and it meets 3 times a week for 6 weeks. Or a general non-science course that is required by the diversified education curriculum...

I used to be pre-med but I switched to chemistry and I'd like to go to engineering grad school. I have to take more advanced physics classes in addition to chemistry but I've only taken the Algebra-based intro class. Can I take more advanced physics classes like Classical Mechanics, Modern...

Hello! I have a project in which I must simulate a blog application,with users' post mangament. These are the requirements: A blog has a title and a collection of posts.The posts have the following information: -author -data -title -text Each post has a code that is generated...

Hello, I am at High School graduate and 26 years old. I try other forums as for suggestions. They did say it is well certainly still possible but I might need to work harder or sitting around people that is younger but it's still possible because of my age. I want to go for Nuclear...

I'm a high school senior going to college next year to study engineering. I'm kind of stressing over these math placement tests that my school makes all engineering majors take. Most students with my major take Analytic Geometry Calculus their first semester. As I mentioned, all engineering...

hello, I just have a question on summer classes, I want to get physics II, calc 3, and differential equations done with before the fall, but I have some concerns all those in one semester would be too much, so here's some ideas I was having. 12 week semester: physics II (along with lab and...

Hello, Since few days, I was looking forward to start some pre-calculus classes...but I am kind of confused with the 'types' of classes offered. Oh and I am in 9th grade...prob. I'll take it next year(its not available in my school, I will probably have to learn somewhere else,can anyone...

Writing "Cram Sheets" for Math/Science Classes... I like to write "Cram Sheets" for Math/Science Class that include my common mistakes, important notes, and any extra information that my textbook does not accentuate or simplify. I like them to be neat and tidy (and hopefully digital so I can...

I usually sit in front of all my classes (middle of the front horizontal row) so unless the professor wanders around class, I should have a clarity. I'm thinking about getting one of those digital/.wma formats from Olympus that has the feature to drown out background noise since I "write loud."...

I know that V, Ord and Card are proper classes because otherwise foundation, successor and Cantor's theorem would be violated respectively. But if a class is in bijection with one of them, why is that class automatically proper? If we don't assume choice, then the cardinality argument doesn't...

So I'm kind of confused about the definition: a-b\in I Why a - b instead of a + b?

I'm taking calculus, physics, com sci, physics lab, and a life science class w/ lab this quarter and I feel like I'm having a hard time memorizing all that material I'm being taught, especially for math and physics since there are so many equations in physics. The homework load is manageable so...

Hi guys I am having trouble with this question (i have attached). Any help with it would be very much appreciated. Many thanks in advance Pete

I was wondering if anyone knows a more efficient method of finding conjugacy classes than the one i am currently using. tex/ Example D_6* =<x,y| x^3=1, y^4=1, yx=x^2y> now to find the conjugacy classes of this group i would first write out the orbit of x <x> ={ 1x1, xxx^2, x^2xx...

hello again, basically just having a question on the classes I'm taking next semester, I'm so far registered for Physics I w/ Calc, a Physics Problem Solving Class (kind of a supplement for Physics I that my school offers), Calculus II, and Discrete Mathematics; these are all repeats actually...

I can't decide which classes to take. Class 1 (below) sounds useful. The group practice in Class 3 sounds fun, but the class starts kind of late. Class 9 sounds great, too, but I'm not sure I can find the class room. Class 11 would be okay, but I'm not sure I like role-playing games. Class...

Is my life over?

So, the question is: Determine all finite groups that have at most three conjugacy classes I'm a little confused by how to start. Right now, we can say for sure that cyclic groups of order 1, 2, and 3 satisfy this criterion. Also, with Lagrange's Theorem and the counting formula(I'm using...

It seems like most schools that I've looked at don't offer a class in full on QM until senior (according to the course sequences they universities have laid out -- these are probably maleable to a certain degree). I am mostly looking at state school as my GPA isn't good enough to get into any...

I'm beginning college winter semester, and am just curious what sort of math classes I would be most appropriate for understanding the mathematics behind quantum theory. I have several years background in cosmology and astronomy, however the subject of the quantum has just been to tantalizing to...

How exactly do placement tests work for most colleges? Do you say "I want to take so-and-so upper math class", and they'll give you a specific test for that class to make sure you have knowledge of the prerequisites? Ex. If you want to place into a graduate-level analysis class, will they test...
