Classes Definition and 568 Threads

I currently go to a community college and they only offer these math classes during the spring spring and fall semester ( not during the summer semester). I just completed calculus 2 and I was thinking I could take differential equations, multivariable calculus, and linear algebra. Anyone else...

Hi When a particular model (say Ising) is solved on a particular lattice (say 2D triangular), do the critical exponents of the same model fall within the same universality class (have same critical exponents) as when solved on a different lattice (say 3D cubic)? Thanks, Mavi

I just wanted to see what you think of these classes for a college freshman's spring semester: Math 220 - Introduction to Linear Algebra - 2 Phil 201 - Introduction to Logic - 3 EconS 102 - Introduction to Macroeconomics - 3 Biol 107 - Cell Biology and Genetics - 4 Chem 345 - Introduction...

I'm an undergraduate math major who aspires to be a quant. Should any finance/economics courses be taken? Or is this portion of the job considered to be trivial?

Hi All, I am reading about screws and screw classes, but can not find any data (such as tensile strength) on screws with the class A4...Best Regards, FlashT

What classes do I need to major in Cryptography?

So, I'm really interested in physics. I'd love to learn the ins and outs of the major theories such as General and Special Relativity as well as Quantum Mechanics. However, I don't believe that obtaining a degree with a major in physics is a wise career choice. Does anyone know if it is possible...

Hi. I'm a second year physics and astronomy major. I'm beginning to worry that I have entered these two majors with unrealistic expectations. The problem is that I developed my passion for physics throughout high school by reading popular science books like The Elegant Universe and Many...

I got my BS in physics and math last year, and am considering applying to physics grad schools, looking to do theoretical physics in possibly condensed matter. I just took the core classes but not any physics electives classes, so would it help my grad application if I enrolled in some extra...

Is there an example of a real vector bundle over a compact smooth manifold with all zero characteristic classes (Euler class,Stiefel-Whitney classes and Pontryagin classes) that is non-trivial?

Homework Statement I have: - 1 class to read a data series (see text file attached) (series.h and series.cpp) - 1 class for a function (function.h and function.cpp) I'm trying to create another class which has input from 2 above class (as constant references) and produce output which has...

Hello PhysicsForums! I have been reading up on congruence classes and working out some examples. I came across one example that I seem to struggle understanding. I've solved for \lambda and I know that \lambda = (3+\sqrt{-3})/2 \in Q[\sqrt{-3}]. I also know that \lambda is a prime in...

Salutations! I believe I have one implications correct and I am looking for a push in the right direction for the other. Homework Statement Let n be an integer and let [a] \in \thinspace \mathbb{Z}_n . Prove that there exists and element \in \thinspace \mathbb{Z}_n such that [a][b] =...

So I'm a physics student interested in taking some systems/signals classes through the EE department at my school. There are 3-4 separate classes I'm interested in taking: continuous systems/signals discrete systems/signals digital signal processing digital signal processing lab I'm not...

Now to be fair, this teacher isn't advocating such essay in all high school physics classes. In fact, he doesn't think it is practical. Still, he asked his honors physics class students to enter the DuPont essay contest...

Hey I'm a junior thinking about going into the mathematical biology field (bio/math double major) for grad school. I have the option of either taking 4 classes (wrong title) to get a biochem engineering minor, the main one which focuses on body regulation, tissue/organ engineering, pathways, and...

Hi, I am new to programming, but I think this is a simple error. For my programming code I am trying to pass a variable from a certain class to another class. The code is similar to below.Class 1 #include "class2" Class2 class var1=1 var2=2 class.acceptingvariablesfrom1(var1 var2)...

When you are studying are you trying to learn what you don't really get, most of the studying time that you put in, or is that time for you more spent, re-enforcing things you already know?

One of my current professors is taking classes over the summer at his grad school. How common is this? I plan on getting a PhD in mechanical engineering right now and assuming I was able to get a job as a professor at a university, would I be able to take classes at that university? I would...

I'm reading the book (Organic Chemistry by John McMurray) for my organic chemistry class at the moment and when I looked at the past exam papers and course structure I noticed it doesn't cover a lot of what I've read so far. My course only seems to cover a handful of chapters in the book. Its a...

I've taken general chemistry I and II, and i was planning on becoming a physics major. I just wanted to know if i wasted my time taking chemistry or if it will go toward a physics degree at most schools. I havnt taken any physics classes yet but should i wait until i finish calculus II and...

I'm taking calculus one right now in community college. I plan to major in physics but the first calculus based physics class requires calculus two, so the only physics i can take until next year would be general physics that doesn't require calculus. I'm not sure what major the class is aimed...

\mathbb R can be defined as "any (Dedekind-)complete ordered field". This type of abstract definition is a different kind than e.g. the "equivalence classes of Cauchy sequences" construction. I prefer abstract definitions over explicit constructions, so I would be interested in seeing similar...

So i just transferred to university and I am taking thermo, physics 3, a lib ed and was thinkin about takin this applied Fourier analysis course. I am just wondering if it sounds like a good idea or should i wait for a few semesters to take it so i'll actually be using it in my classes. Thanks

Hello, I'm here looking for some peer guidance on what electives are more appropriate for a sound (and full-range) background in a physics undergraduate program. My hopes are to attend Graduate school in about two academic years. As of now I'm a junior and just getting into the upper level...

Homework Statement Let S := (\Re x \Re \ {(0,0)}. For (x,y), (x',y') \in S, let us say (x,y) ~ (x',y') if there exists a real number \lambda > 0 such that (x,y) = (\lambdax',\lambday'). Show that ~ is an equivalence relation; moreover, show that each equivalence class contains a unique...

Starting next semester, I will be taking part in a year long, accelerated math program, which if I finish, will allow me to get a master's degree in place of a bachelor's. My primary major is physics though, and I have been considering the possibility of substituting some of my required classes...

Hi I have a few more courses I need to take to finish my degree in math. I'm considering taking them online. I'm wondering if anyone could tell me their experience with either Athabasca or Thompson River Open Learning. The courses I'm thinking of taking are...

Hey everybody. I'm a freshman in college thinking about double majoring in physics and math. I think I might want to try to get into physics research as a profession, and I think knowing how to program might help me. Someone, however, told me that computer science courses aren't the type of...

Hello, I am an electrical engineering student and i am wondering what classes would be handy to take that are NOT required in the curriculum? I've thought about linear algebra but I'm not sure if it would just be a waste. I want something to give me an edge over the others whenever i enter the...

Long title, but basically a good summation of my question. I hate summer time, every year it's made me feel like a lousy losing loser with all this time on my hands and I never get anything done. So I'm taking 3 classes at a local community college (this is my very first semester of college...

It's often said that the axioms of ZFC set theory are the foundation of mathematics, but the same people who say that also use the term "class" a lot. For example, "the class of all ordinals", is apparently too large to qualify as a set. What's bugging me right now is that I read that there's no...

I'm in the U.S. and i was wondering if you have to take the general ed classes before the classes that relate to you degree. like the general ed classes could be English 1A, some history classes, etc.. just those. I thought that after you graduate high school you can immediately start working on...

I'm leafing through "Engineering Mechanics - Statics" by Hibbeler, and it seems almost entirely a review of my Physics I class that was on Classical Mechanics. How is a class dedicated to Statics or Dynamics (both of which I will have to take) different from my classical mechanics class? It...

Homework Statement In a high-school graduating class of 100 students, 54 studied math, 69 studied history, and 35 studied both math and history. If 1 of the students is selected at random, find the probability that (a) the student took math or history; (b) the student did not take...

I am currently in BC Calculus. Next year, assuming I do well on my AP tests and placement exams, I will be able to go into Linear Algebra. I plan to major, or at least minor, in mathematics. The school I am going to will not require me to take Calculus 3 next year since I have BC and will be...

How negatively do UC schools in California view retaking classes ? By the way, altogether it would be about 8 W's & repeating about 6 classes total. How about, if you have a 4.0 but retook classes and got A's, however got D's in them ALL the first time, would you have a very good chance of...

Best math classes for a physics major?? So I'm double majoring in physics and math, what are some beneficial math classes? REQUIRED FOR A MATH MAJOR: - Calculus I - Calculus II - Calculus III - Linear Algebra - Abstract Algebra - Differential Equations - Intermediate Analysis -...

I know this may be a naive question but here is my situation. I'm going back to undergrad this fall for a 2nd bachelors degree in Physics, so I'm planning on getting a head start by taking Calc II and Physics I with calc at a community college this summer. I plan on applying to grad school in a...

I am currently a junior in high school and I am deciding on what classes to take for next year. As of now I am signed up for Physics C(mechanics) and AP chemistry as my science classes. I took Calculus AB this year and I didn't do too well(didnt stay caught up with the homework) and I'm not...

I am in a program at a community college to get my associates in engineering. I was thinking about changing my major to physics but they don't have a physics program. i was wondering if i could put the classes i take for the associates in engineering towards a bachelors degree in physics.

I'm currently in a transfer program at my local college. I have a few choices on what electives to take for my engineering degree, and I'm looking towards mechanical engineering (I'm fairly sure it will be mechanical but it's possibly I may go for electrical in the future). I was wondering which...

Hi I am struggling to get my head fully around the conjugacy classes of D5. Everywhere I have looked seems to say that there are 4 irreducible representations of D5 which implies that there are 4 conjugacy classes. However, when examining the symmetry of the pentagon I am only able to see 3...

this problem is from Apostol's Calculus Vol.1, i just started doing proofs so I'm still getting used to it. B - U (A) = ∩ (B-A) the U is the union of sets in a class F and ∩ is the intersection of sets in a class F. written under both the U and the ∩ are A∈F. so i let an element x ∈ B...

I'm working on a Physics/Mathematics double major at Oregon State, primarily focusing on physics, and I want to know which upper division math courses best synthesize with a physics program in graduate school. Right now I'm leaning toward Astrophysics. Of the classes described...

Hi all, First I just want to say that I find this forum really interesting and very helpful - so thanks to all those who answer these questions! Onto my questions - I am a Junior physics major considering what classes to take next year. I am lucky enough to have all of my requirements...

Intermediate algebra and algebra 1 are both 5 units and then college algebra is only 3 units, so is college algebra easier then since it is only 3 units ? (At a 2 year college)? going from algebra 1 to algebra 2 (Is there much difference in the level of difficulty between the two?) or going...

Is it possible to do well in upper level physics classes with a weak foundation in differential equations? I've never taken a DiffEq class. Some of the extreme basics were covered in Calc 2, and there will be a crash course in DiffEq in my Mathematical Methods in Physics class (using the Boas...
