What is Classes: Definition and 592 Discussions

May sound bad, and I'm sorry if it does, but I want to boost my GPA with some easy classes in addition to my sciences and maths (FINALLY decided to take that required science major biology... ugh) So far I have Intro to Health & Phys Ed HPED 252 Careers in Sports Medicine ATTR 101 Intro...

I am surprised that I don't see topics like this but anyway, I am thinking of taking math classes outside my engineering major sheet which is called foundation of mathematics it deals with sets and proofs described :"Algebra of propositions, mathematical induction, operations on sets, binary...

okay, Through lurking, I've gotten a better understanding of how to tackle math, physics, and chemistry classes. My question is then how would you tackle Engineering classes? namely my CBEE 211 class. I know the key is practice, but this class takes a ridiculous amount of time. It's nice to...

Okay, so there are some non-required classes that I'd like to take (that would probably help with my overall GPA). But in the end, is it better if I simply spend those hours in research, if those classes might interfere with my research output? Here's a big thing though: my *total* overall...

:smile: : 1. I am an engineer seeking to fully comprehend Set Theory, Logic, Probability; especially as it relates to equivalence/classes, class invariants, etc., in the context of an essay that I have posted at http://quantropy.org/12/ [6 pages, 194 Kb, 31 references]. 2. The essay relates to...

I'm about to apply to applied math grad schools. I completed the general GRE tests, and took the physics gre but not the math subject GRE. There are some schools that will look at my application, though they can't guarantee that my application will be treated equally as an identical one but with...

I'm in the process of getting my application to grad school completed and have a number of "5000" level classes that I'm not exactly sure how to classify on my my applications. Is it appropriate/acceptable to list ALL of them as "graduate" classes that I've taken as an undergraduate...even...

I have two universities near me and I emailed them to find out what classes I need to take in my community college for a transfer as a physics major. One of them emailed me back giving me a list of classes I need to take. Four physics classes, four chemistry classes and three math classes. Then...

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?

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...

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...
