I am completely lost. I just started my O.D.E course this week and I'm already sinking. After the first lecture I was reading through the chapter (because that normally helps) and I became even more confused. I looked at the homework, and I didn't even know where to start. Then I realized (with...

Hello, If anyone could help me with the prerequitisetes for an undergraduate General Relativity and Cosmology course I will enroll into, It will be much appreciated. The syllabus is the following(sorry for the rough translation): -Review of Special Relativity -Spacetime in GR -Geodesics...

Hi All, I found a free online course Physics from Yale I thought that must be pretty good well after watching the lecture and starting with the first problem I think I found something that is incorrect. Is anybody willing to tell me that i do somehting wrong (most probably I would expect that...

Dear Physics Forum personnel, I will be taking my first graduate course (as an undergraduate) in mathematics starting on this Fall Semester. The course is about the algebraic topology (Hatcher, Spanier, Massey, etc.), which I am very excited to take as I love the topology. I am curious about...

Hello! I am currently searching for some alternative books I can use for the analysis course starting on this Fall Semester. The course will cover the compactness, contraction principles, approximation theory, and some applications like special functions and Fourier series. The required...

Greetings. I've come with yet another issue which is causing me some distress. So I took everyone's advice and started self-teaching calculus (or at least I started trying... Limits are still confusing). However, my problem doesn't stem there. I decided to review my algebra before year 10...

Hi guys, I'm thinking of maybe of studying differential geometry as part of my undergraduate degree. However, it's not for physicists, it's a full on formal mathematics course specifically for mathematicians. I'm not sure whether it's a bit overkill and won't actually be useful. We don't have a...

So i am currently going into my third year in the fall and this summer I'm taking a few courses and finally got my first opportunity to participate in some research. Problem is there is a good chance I will get a NP (not pass) in a GE class I am taking. I am going to a UC so an NP does not...

Background: It has been about a year and a half since I took Calc 3 so I am not as familiar with using derivatives as I would like to be. Basically my math dept. had a concentration in math-stats that didn't even require differential equations at all, so I wasn't expecting to take the course...

Hey guys, I checked through previous posts, none that I found quite matched what I'm looking for so i thought I'd create a new one. I apologize in advance if someone finds an identical topic, by all means, link it to me! Anyway, I'm in a position right now where my job is entirely remote, and...

I'm about to be a junior in chemical engineering. I've passed all my calculus/ODE and general physics/chem courses. The most intense schedule I've taken at once was calculus 3, ODE, and general physics 2 (introductory E/M at my school) with a lab component. I did very well in each course and...

Hi everyone. For anyone who has the book. I am going through Quantum Field Theory for the Gifted by Amateur Tom Lancaster and Stephen J. Blundell. Are the topics enough to prepare me for a course in QFT and then Advanced QFT? Of course I can look for other resources. But I just want to know how...

Hi, This October I'll open my physics undergraduate studies :D ♥♥♥ And as you all know, first things first - mechanics. I realize that it includes dealing with simple differential equations and that the accompanying mathematical explanations are not totally satisfactory. Therefore, I intend to...

Hi all, I'm starting my grad work in September and I'm trying to decide which courses to take. I'll be doing an M. Sc. in Chemical Physics, and potentially a Ph. D. My undergrad was in Chemistry, with minors in Physics and Math. My tentative choice of thesis topic is coherent control...

What should I review for an introductory probability course? Here is the course description. Math 224 I believe is Calculus 3 at this school( multivariable). 380. Probability and Statistics (3) Prerequisite: MATH 224. Frequency interpretation of probability. Axioms of probability theory...

I am currently in the first year of a 2 year diploma program for mining. It's a full time program with about 8-9 courses per semester which comes out to around 29-31 credit hours. I felt I struggled quite a bit getting through the first two semesters I got two C's last semester and I felt I did...

So in conductors, the electrons will distribute themselves to the surface via repulsion forces. But why do we say that the electric field inside is zero? If I put a positive charge inside, clearly it will move in some direction from the electric field of generated from the electrons. Also, are...

Hi, I've been really looking into going back to school for awhile now, and I don't know exactly what I want to do, however I can't see myself doing anything not related to math and science. The circumstances in my life are progressing in a manner that would make it financially feasible and...

Pure math books, in my experience are very hard to read(compared to engineering). An engineering book(in my experience) keeps repeating the same math(high school calculus+some engineering math) again and again. So, after time, the pattern of thinking become more normal. But math books on other...

Hey everyone! I started back at my university after a 3 & 1/2 year break and changed my major from Journalism to Physics last May. I am coming up on my finals in a couple of weeks for the Spring Semester and then I will be taking a class over the summer and doing research. My grades are great...

Suppose we have an elementary double-slit experiment: A laser fires individual photons through a double slit at a detectionscreen made of atoms. As we fire photons, an interference pattern emerges, exposing the momentum of the photons (the frequency of the laser). So, we have registration of...

Hi all, I am a student in Mathematics who has recently discovered a small interest in Physics. I will be graduating next semester, but I will have the opportunity to take an extra class of my choosing. I have already completed the year-long Physics I and Physics II sequence covering elementary...

Hi, I am currently in the first year of my undergraduate mathematics degree and I am taking a course in vector calculus. The course content is: line integrals, conservative field, divergence, gradient, curl, the divergence theorem, green’s formula, Stokes' them., field theory. I have seen that...

This article sounds or reads like the same old problem: http://news.yahoo.com/algebra-unnecessary-stumbling-block-us-schools-170616735.html Why should that be? Students fail algebra 1 either because of lack of effort, lack of motivation, or, if for any student the course is difficult, the...

I'd, of course, want input from people who are far more smarter and experienced than myself in academia. But I think the best and most fairest way to judge someone's grade for the course is to have a balanced variety of different means to gauge abilities. 15% Mid Term Exam 15%...

I'm a senior electrical engineering major and am actually having fun in this mathematical computations course I'm currently taking. I'm trying to find out what kind of math course would be beneficial in obtaining a deeper understanding Maxwell's Equations, basically gradients, dot products, and...

Hi, I want to pursue a degree (engineering preferred) that would teach me about computer hardware and instill the skills required to begin a microchip startup.

I am trying to work my way through Stephen Pope's "Turbulent Flows". I'm finding that my Achilles heel (as has been throughout my undergraduate degree) is maths. Since this book is essentially applied maths, I'm finding it difficult. So I'd like to simultaneously work through a course in...

Homework Statement The question as follows: Calculate the energy that is required to accelerate a particle of rest mass ##m\ne 0## from speed ##v## to speed ##v+\delta v## (##\delta v \ll v##). Show that it would take an infinite amount of energy to accelerate the particle to the speed of...

Hi I'm in the tenth grade and I have always had the dream of becoming a surgeon. I realized I would like to be a plastic surgeon since grade 8. I plan to eventually move to korea and specialize there. I was wondering what courses should I take? I have already taken science 10 in the summer and...

We had a class on optic nerve today. Our teacher said that the optic nerve "originates" from the retina, and continues up till the commencement of the optic chiasma, and is, approximately, 4 cm long. My question is, Why is it considered to be a cranial nerve when it does not even originate...

I got to choose 2 lessons from these 3 for optional courses. I'm studying mechanical engineering. Which ones are the most important in your opinion? Available options are: 1) Thermodynamics II 2) Material Science II 3) Technical drawing II with CAD software ( teaches Solidworks previous year...

Hi guys, I really need help with deciding my courses for next year. Currently, I'm a sophomore in high school rising to a junior next year, and today, we began doing course selections for next year. Now, before I continue, I didn't just start thinking about my courses for next year today. I've...

I will be transferring from a community college to a university where I will be taking Physics II. We will cover electricity, magnetism, waves, optics, and perhaps even some modern physics. The catalog at my new university says that a co-requisite is Calculus II where they cover integration...

I am in a course of Computer Science Engineering.I have noticed about by personal temperament that I learn better on my own than I do under authority. I learn better when I am reading books and studying on my own than when I am sitting in a class and listening to six hours of people talking...

Tomorrow I embark on a new semester and this semester I have the pleasure of learning applied partial differential equations and the software of "ROOT" ROOT: https://root.cern.ch/ So I am here to solicite advice. 1. In regards to ROOT, is there anything that can set me up better for a more...

I'm thinking of taking a course called Atoms, Molecules, and Solids this semester and I wanted to get a feel for the material beforehand to see if I'll like the course. If anyone could recommend a textbook based off this course description, I'd appreciate it: Quantum theory of atoms...

The question is as follows: Prove that any timelike vector for which ##U^0>0## and ##\vec{U}\cdot \vec{U} = -1## is the 4-velocity of some world line. I need to show that there exists a 4-vector ##\vec{x}##, s.t ##\frac{d\vec{x}}{d\tau} = \vec{U}##, where ##\vec{x}## is a world line of some...

If this type of post is not allowed then I completely understand if the mods have to remove it. So I'm a first year Master's student and I'm soon about to take my Real Analysis final exam. I know I'm going to fail the exam most likely as I have to be able to remember all of the homeworks (which...

I teach a bit of special relativity to non-majors enrolled in the typical two-semester introductory college physics sequence. These are my goals. 1. Have the students develop an understanding of the basics such as length contraction, time dilation, relativity of simultaneity, energy, and...

Odd question, but I am in a very bad situation. I will preface by saying that I am a straight A student (I have managed to make it to my junior year with my 4.0 still intact), but I have just landed in quite a terrible position. I am (or was) on track to get an A in my circuit analysis class and...
