What is Classes: Definition and 591 Discussions

Hi, I'm currently in "gymnasiet" in Denmark, which I understand is similar to high school in the US. It's what gives you access to universities, so to speak. After "gymnasiet", which I'm done with summer 2019, I'm planning on going to university for a physics degree. I'm currently taking...

My situation: I am an EE major, first year, 6 quarters ahead in math (meaning i have 6 "extra" slots for electives). I will probably take many CS courses, or maybe switch into a combined CS and EE major (like ECE or CSE), partially due to interest and necessity of coding skills nowadays. I also...

I began by creating 2 classes. A book class and a course class that contains any necessary info about the book and course respectively class bookClass{ private: string theISBN; string thebookName; string thebookAuthor; double thebookCost; int...

Sophomore Intended Mechanical Engineering here. I have a pretty nice schedule this time around, all STEM classes. Most are easy but I have Differential Equations, Physics II, and Statics which are the hard ones. I have a lot of free time to study over the next few weeks and wanted to try to...

Hi, I hope my post will be clear enough, because I got a lot of things on my mind. Some details about me, I'm a student in the best college in my country for engineering/science etc... I study a combination of EE & CS. I think I'm smart, although I have to work very hard in order to grasp...

I'm finishing up my first semester of college this month and looking ahead for long term planning and I'm in need of a little insight. This was my first semester and I took 6 classes (all entry level generals like basic Chemistry, Psychology, History, etc) and worked pretty hard to get A's in...

Could you suggest any source giving a good systematic overview of all phyla and classes - extant and extinct? From https://en.wikipedia.org/wiki/Phylum the list of animal phyla is suggested as 34, but controversies exist Some phyla have no fossil record, some fossilize with great luck, some...

This is a class assignment that has been puzzling me for a few hours. I need this to print out the values from the passenger array. My code so far prints the values from my aircraft class perfectly but not from my passenger class. Please see my output below: How do I make the output display...

I work 20-25 hours a week, am a physics major, and am currently signed up for Mechanics 1, Mathematical Physics, Intermediate Lab (An actual course - not like general physics labs), and Linear Algebra. I've taken Linear Algebra before and dropped it about halfway through the semester because I...

Merry Christmas everyone! I have a question and I want some honest answers. So this semester I took Organic Chemistry 1 and Calculus 1. I both passed but with a D, sadly the courses won't transfer to my school I want to attend in the future (waiting for a response from the schools I applied...

I'm not sure if this is the right section but.. During the semester it feels like we are learning a ton of stuff at a crazy pace, but then when the semester is over I always look back and am like "that's it? I've learned everything about X class that I will need to know for all of my future...

my name is Angie, in high school I suffered anxiety, my performance in class was non-existence. which lead me to believe I was "dumb" .. Now that I am in my twenties I realize after " finding myself" I want to be a registered nurse. so here I am upgrading my grade 12 courses. I finished...

Each bead on a bracelet with three beads is either red, white, or blue. Define the relation R between bracelets as: (B1, B2), where B1 and B2 are bracelets, belongs to R if and only if B2 can be obtained from B1 by rotating it or rotating it and then reflecting it. What are the equivalence...

Hi,I am a sophomore and for the past 2-3 years I have been studying quantum physics, astrophysics, general relativity, force, energy etc.(you get the gist). I was wondering on how I should got about taking (physics or chemistry) classes to pursue my dream of being a physicist of some sort?

There's something that I'd like to know and haven't been able to find in any book: 1.- Is the number of second order phase transition university classes known? 2.- Do we know quantitatively know the behavior of all such second order phase transition university classes? 3.- Do we know the...

Hi, Just curious if someone knows of any Characteristic class used to determine if a manifold allows a Complex structure? It seems strange that Complex Space C^n is topologically Identical to R^{2n} yet I believe not all R^{2n}s ( if any) allow Complex structures. Thanks for any comments, refs...

My school offers both Elementary Differential Equations and Probability Theory in an 8-week summer session every year. Both of these classes are undergraduate prerequisites for the graduate program I'm applying to, and I anticipate that I'll basically need to take both of these courses...

Don't worry it's still summer break! :smile: For most students classes start in a few weeks. When is your first day of instruction and what school?

This upcoming fall semester, I am planning to take Calculus 2, which at my school is the prerequisite for 5 other math classes I need to take. I would like to take all 5 of them the following spring semester, but I don't know much about the courses (for example, how difficult they may be) and...

Hello all, I am a rising sophomore physics undergraduate and I have a few questions regarding taking graduate courses as an undergraduate. Currently I am signed up to take Quantum Field Theory and a graduate classical mechanics course in the fall. Now graduate courses are expensive, about $1000...

Hello electrical engineers and hobbyists of PhysicsForums! This is my first post (I think... I might have posted before) and I am a junior-year EEE student at a local University. I have some free time this summer and want to study/review some concepts to be fresh when I need them for my...

There's a lot of questions that float around like "I'm an EE major, should I double/minor in math?", "What math classes should I take as a physics major?", etc. After I typed in the title, this already started to show. Maybe you will disagree with some philosophical points I make, but I think...

Next fall I'll be a junior, and I'm wondering what classes besides physics I should take. I'm already on track to taking the necessary physics courses so that I can complete my degree. I'm just wondering what electives I should take. Introduction to computer science? Geology? Creative writing? I...

So, I want to apply to a graduate program in physics in the fall. I have a decent 3.5 overall gap (3.8 upper level physics), but I feel like my course work is light. I'm graduating this semester and am contemplating coming back for a few more courses (maybe graduate) to strengthen my application...

I used to think that gen ed classes (like literature, humanities, fine arts) were a waste of time. Now, I realize that they have value within a lucrative major. The purpose of college is to be well-rounded academically. It's what makes a college degree different from a 6-month nursing course...

i would like to be a heart surgeon but what classes should i take? I am in ninth grade and have a 96% average in all my classes but what would help me to get ahead in college?

Hey folks, As a sophomore in MechE, I'm now taking a first course in Engineering Statics, and the prerequisites to this class are Physics I and Linear Algebra. I did well in those classes in past semesters, but I can't really say that I remember everything. I wonder how much do you usually need...

Hey people, I need some help, preferably from the Electrical Engineers... Classes start next month and I'm stuck deciding some electives to take during my third mechanical engineering semester. Here's the thing: I decided to take some electives from the EE department so I have a good basis to...

Hello everyone, I'm a high school student and wondering about the rigor of the AP Calculus classes that U.S. high school students often take. When I say rigor here, I'm talking about mathematical rigor as is commonly talked about with regard to math classes, and also whether or not the class is...

Course Selection is coming up next week in my school and I am still deciding between 2 slots and 3 desired classes of mine. In my school we have 8 classes all together with 4 on "A" days and 4 on "B" days. Here are my selected classes that have already been picked out: Honors Biotechnology III...

Hi all, I'm a freshman that's about to begin my second semester taking 3 technical courses and 1 gen-ed course. I've gotten accustomed to studying for math and science classes in university, but I have to take this non-western gen-ed (and due to scheduling conflicts with my main 3 classes, I'm...

I know that this might seem a little stupid question, but I'd like to read some answers or maybe see some examples (better put as problems for my own practice)? I don't understand how the concept of friend classes is useful in programing. Classes, in my understanding, are supposed to be some...

I am planning on transferring to a 4 year university to major in physics. I am currently overseas and must take classes online. After an almost endless grueling search I was able to find a school that offered an associates program online that I feel is in the right direction for what I intend to...

Homework Statement Hi,I am stuck on my maths assignment. Describe equivalence classes for the following equivalence relations on the given set S. (i) S = R, and a ∼ b ⇐⇒ a = b or −b. (iii) S = R, and a ∼ b ⇐⇒ a^2 + a = b^2 + b. (v) S is the set of all points in the plane, and a ∼ b means a...

I am in differential equations and I really wanted to go into applied math but this is the first math class I have taken that I detest. I really enjoyed calculus 1-3 and linear algebra especially which made me want to pursue applied math but differential equations is just not appealing to me at...

Hi All, I am a EE student and thinking about doing the following classes in Spring 16 - Signals & Systems + Electromagnetic + Physics 3. Any suggestions is Emag and Signal and systems very hard?, what Math do you need? (Dif Eq) Is it a bad a idea taking these classes at the same time...

Are the four classes of quantum mechanical phenomena for which classical physics cannot account independent of one another or can one derive one or more phenomena from other(s)? These according to the Wiki are: Principle of uncertainty; Wave-particle duality; Quantisation of certain physical...

Hey, guys. I'm in the 11th grade. The current class that I'm taking right now is called "Computer Programming 11" which is an intro to programming. The entire course is spent learning how to use Microsoft Visual Basic which kinda disappointed me because I originally signed up to learn Python...

I've seen several threads related to my question, and I have tried to utilize the information found within them to answer part of my own question. I'm a physics major, and after looking through my universities requirements I've realized that the physics major leaves me just a few classes shy of...

If business degrees require only intro to stats class that contains no calculus, and stats could be summarized into a short, easy, one semester course, are taking calculus-based statistics courses after intro to stats helpful for decision making, or are the calc-based stats courses merely just...

My professor was proving that the Dodecahedron is isomorphic to ##A_5## and in the process utilized the stabilizer (which one can intuit ) of an edge, vertex or face to determine the conjugacy class (which is hard to intuit) of elements of the same order. This seems like a valuable skill but I...

I was always aware that AP classes were, in general, not equivalent to their respective college courses, but I'm beginning to wonder if the gap is much larger than what I previously thought. Many of my suite mates are engineers/physicists, and so most of them are taking the same physics...

Hey everyone, I'm just curious what undergrad mathematics courses are traditionally more proof intensive. The reason why, is that although I'm a physics major currently, I (generally) really enjoy doing mathematics, just for the sake of mathematics... so I regularly have thoughts of "maybe I...
