Hey I was curious if it is entirely possible to learn quantum physics up to current knowledge without having to go to university with the right books and material found through out the net/libraries. I'm more of a interested person than some one seeking a career into the subject. So it...

Folks, I am currently studying undergraduate final year degree in mathematics. I have covered QM's, PDE's and currently studying Functional analysis and vector calculus/complex variables. I hope to finish the degree middle of next year, however I would like to continue studying...

I cuurently have Larsons Calculus alternative 6th edition and was woundering what would be some other good calculus books to purchase, how about calculus for dummys too? I'm self studying so what sort of books would be best for this

Could anyone give me some tips on self studying? I have a Calculus book from my high school ( I am alloud to use it for the remainder of the year...but I am NOT in calculus) So could anyone give me some tips on selfstudying skills, it would be extreemly helpfull, I just started on chapter 1 and...

I dropped out of college five years ago, before my studies really had begun. My original plan was to start again my engineering physics studies in January but my problem is that some of the courses available for spring are continuing on the fall studies. Now I got a bit surprising turn of...

Hello, This is a bit of a random question, but I thought I would ask it here. I am interested in doing a PhD in engineering in the UK. However, of course, funding is extremely difficult to come by. I was having a conversation with a friend who said that her cousin paid for his by working...

Hello everyone, could you please make me understand, what are self-adjoint equations? and how can we convert a differential equation into a self-adjoint form? Thank you.

Fellow Engineering Lovers, Being a mechanical with limited electrical I must turn to the electron masters for answers. I have a PM brushed DC 12 V fan motor on of a standard electric cooling fan on a car radiator. My calculation comes out to be about 90 watt. I also have PWM 12-24 power...

Hello folks. I have an electromagnetics quiz tomorrow and I am kind of nervous. I can't seem to grasp the concept of induction, more importantly how it differs in AC and DC circuits. So in lay terms: Induction is production of electric current across a conductor which is moving through or...

I’ve been looking at this “Self leveling pallet fork” which is supposed to, as the name suggests, keep itself perfectly level regardless of the load applied. I guess I can see how it would adjust itself depending on the weight, but I just can’t wrap my head around how it can possibly adjust...

Am I being lulled by a basic text? I am re-studying basic physics and calculus for a run at a physics degree. I am using the Stewart text for calculus and I find it challenging. I am using the Young and Freedman physics text, and I find the calculus-based portions incredibly basic. I am...

Hello everybody, Well I'm a level 4 mechatronics students from Mauritius and doing my project on a self balanced bicycle which uses a flywheel to achieve this.A better view of it can be seen on: OR EVEN ON: http://www.youtube.com/watch?v=0312BNqIBFI&feature=related...

Hey. I want to get up to an SAT II level of physics so I can skip it next year and go straight to AP Phys. Only thing is, I don't know of any textbook that would work well. Which textbooks would you guys recommend to get to the sufficient level of physics so I can test out of it? (In my school...

[1] When self studying, do you memorize vocabulary words and things like that? This isn't like taking a course where the teacher tells you what to memorize and what will be on the test. When self studying how do you separate the stuff? Or do you literally study the material "inside out" as in...

Homework Statement hi! first off, thanks for viewing this. I wasn't sure if this would be the right place to post for help, but it's for an engineering challenge so I didn't know where else to go. Also, I'm really sorry if this is a repeat thread, I don't really have time to read through...

Hey guys, I'm usually not this candid but I need some help. I am looking for suggestions on things to do to improve my self discipline. I've never really had strong self discipline, I have always had trouble with procrastination and slacking off when effort should be put in. I have a weak...

First of all, i would like to appologise if there is already a topic related to this on which i could have posted. I was not able to find it but also only skimmed through the search results. Mathematics has not been one of strong points. In middle school i struggled with it - i didn't spend any...

I'm not really a big fan of computers but I understand there importance to physics. My school offers computer programming classes for engineering and science majors but I don't want a extra formal class that isn't required. Do you think it would be a good idea to self learn all of the programming?

I'm going into my second year of applied math and engineering. My problem is that my degree requirements do not allow me to take any courses on quantum mechanics. Therefore, I am thinking about teaching myself from a textbook or something of that sort. I was wondering if someone could give...

Hi, I'm currently self studying "Principles of Quantum Mechanics" by R. Shankar. (Its prep for research, a Prof. recommended the book.) I have only done 2nd year of intro to QM which only covers 1st few chapters of griffiths. (Know multical) I find myself having a hard time going to...

We all need to come to terms with the terrible ordeal our country have been through; for the relatives of our 77 dead, the almost 100 wounded and the 500+ terrified youths who survived physically unscathed, such processes of healing may take years, if they ever can be said to heal. For me...

let me preface: i know nothing about neuroscience. it seems that at a fundamental level, everything is either detectable, or you can theorize about ways to detect it. shouldn't particles (neurons or whatever) in the brain emit waves, or any kind of signal, that indicate their interactions...

I'd like to study math on my own at home so that it will make me a better student of mathematics. I am in college and have recently finished Calc II. I got an A in both calc 1 and 2 but yet I am unsatisfied with my knowledge and skill with the subject. My goal is to prepare myself for the...

I will be attempting to get a PhD in statistics eventually though I have yet to get my BS, however, in the mean time I have a few electives I need to fill and I want them to help me in my self study of relativity and quantum mechanics. I will not be surpassing a Master's knowledge of these areas...

When I self-teach myself mathematics or physics for that case, I like to run through every single problem in the chapter. The outcome... teriible terrible pace... Is this necessarily a bad thing or a good thing? How do you guys study mathematics? In need of advice. Thank you.

Can you give example of systems that self collapse? For example, is radioactive decay an example of self measurement? How about 13 billion years ago when stars were just being formed, is it an example of self measurement? Because I can't imagine how stars can form when all things are in...

Hi, I'll be beginning my high school sophomore year in August and will be taking Precalc in school, but, because I want to start studying physics seriously, I thought it would be a good idea to take initiative and get a solid foundation in the required math before classes start (an entire...

Homework Statement In an effort to keep me from spending all summer lying on the couch, I recently started reading Michael Spivak's Calculus on Manifolds; while working on problem 1-6 I got stuck on a technical detail and I was wondering if anyone could provide a little insight. Problem 1-6...

In an effort to keep me from spending all summer lying on the couch, I recently started reading Michael Spivak's Calculus on Manifolds; while working on problem 1-6 I got stuck on a technical detail and I was wondering if anyone could provide a little insight. Problem 1-6 says: Let f and g...

Hey so I'm trying to self study for both AP Physics exams for May 2012, and I've been going through halliday & resnick 7th ed. as a text, however, I feel that this book isn't helping me so much for the mechanics side of things (as I haven't begun to study E&M stuff yet) for two reasons. First...

I'm having trouble showing that any normal linear transformation T is the sum of a self-adjoint transformation T1 and anti-self adjoint linear transformation T2, (so T=T1+T2) so that T1 and T2 commute. Anti-self adjoint being <Ta,b>=-<a,Tb>. Specifically I'm not sure how to use the information...

Hi, I'm in my second year of my degree in Physics specialising in Theoretical Physics. My second year is coming to an end now and next year we will begin a course called Advanced Classical Physics (ACP) which will introduce Lagrangian and Hamiltonian mechanics as well as SR and...

can somebody explain about this self energy??

Hi, I am currently in high school (Year 9) in Australia. I would like to self study high school physics so I can prepare for my HSC earlier. I finished all the year 9 maths and I'm currently up to quadratic formula. I have yet to do curves and logarithms. Can you please recommend me any...

I am a student @ UK COE in Lexington. My original plan was to complete my sophomore year @ UK and then transfer to UT Knoxville to do NucE. I live about 60 miles south of Lexington and have come to realize I cannot afford the gas in the fall to go to UK. I have been forced to register at a...

Does a circle have a constant rate of change of it self that defines it as a circle. I have never heard of such a thing but I am curious. It must right?? Since every circle is the same no matter the radius(the arch will change by some constant amount per radian) If that doesn't make...

Hello, I was hoping that someone might be able to provide a definition for the "resonance self shielding correction". -TP

I have two main questions: 1. What's next? I have taken several physics courses(covered both mechanics, E/M, wave motion, fluid dynamics, and special relativity) in my high school career. I want to know what i can learn next? (preferably not quantum) The reason I ask is because I love...

So this fall is going to be my first full semester as an EE major. Here's my classes: Introduction to Circuits and Electronics This course introduces linear circuit analysis and design including extensive use of op amps. Presents DC networks, including node and mesh analysis with...

Self Propelled Golf "Pull" Cart Hello everyone. I am quite the novice when it comes to stuff like this but I was wondering if anyone would be able to help me with a project I would like to undertake. My idea is to build a golf “pull” cart with some sort of DC motor that might run off a battery...

I'm an engineer student, and I think I need a refresher on everything from algebra to calculus. Would definitely appreciate it if some of you can provide recommendations for some math self study software.

Do you have any stories of people successfully self-studying a relatively advanced subjected in which they've had absolutely no coursework? Personally, I've taken some honors level courses in high school and then done some extra studying to get on a good enough level to take the AP test. I've...

I'm sure there are many like myself who are self studiers: read the book, do the problems. Right now I'm working through Halliday, Resnick and Walker, Fundamentals of Physics, and doing all the odd problems because the answers are in the back of the book. I'm also watching the MIT OCW lectures...

Hi all, I am trying to find numerically the eigenvalues of a nonlinear schroedinger equation in a similar way as the Self Consistent Field method for Hatree-Fock problems. Does anybody know in the SCF calculation how to improve the convergency? Is there any trick other than simply inserting...

Hi, I have been calculating the 3 infinities in QED as part of my project (vacuum polarisation, vertex corrections and electron self energy). Mostly I have been following the description in Mandl and Shaw for determining the first two (chapter 10, sections starting on p211). However it does...

Hi, I am grade 11 in high school I got my grade 11 math and physics credit and i thought i want to move on and study grade 12 and more (maybe even university level) I always loved math and last semester I tried physics for first time and it was awesome (except optics,, hahaha personal...

I'm thinking of teaching myself some topics in maths and physics for fun over the summer. However, I've found that I usually need a teacher/lecturer to explain some concepts to me when the books go all sketchy in those areas. I need this especially when I can't see where I've gone wrong in my...

I am taking calculus b but for some reason it seems to be a shorter version according to my instructor. We are using james stewart 6th edition but only taking chapters from 7-11 excluding 10 which are 7_Inverse Functions: Exponential, Logarithmic, and Inverse Trigonometric Functions...

Hi all! I am a current senior in high school, and will be finishing BC by the end of this month. I do not yet know where I am going to college, but I am planning on trying to place out of a few math classes before arriving. II will most likely major in engineering, but I still am interested...
