We are going over capacitors in AC and DC circuits in my circuits class and I was reading over the applications of capacitors. It is mentioned that they are used for filtering in power supplies and there is some stuff about full-wave and half-wave rectifiers. I am confused on how all of this...

I'm pretty sure there was a grad school FAQ sticky, but I can't find it (am I just blind?). Search didn't bring it up. I've heard a lot of different things about grad school applications. Grades are everything, all that matters is if you've done research; being published is a huge boost...

I just started learning about DE's and am impressed by how much information they contain. Are they usually just a relationship between several simpler functions? For instance, a basic kinematic problem like v = at + vo seems quite hard to come up with experimentally but v = d/t would be...

The rate of capital growth in a bank account is described by the differential equation dM/dt = aM Where dM/dt is the rate of change of the capital M and a is the annual interest rate. Show that the general solution for the time dependence of capital M(t) is given by: M(t) = M0 * e^at...

This is probably a commonly asked question but I felt id ask it. If your studying math and you get really good at the good basics of math, algebra, linear algebra, real analysis, differential equations, PDE's, calculus, trigonometry, etc. etc. I can see a lot of small examples of where it is...

Homework Statement Does anyone know what applications has Meissner effect? I have search on the internet but I did not find much only that the effect is not really of great practical use because it only occurs with superconductors, most effectively with type 1 supercondustors which have to...

Homework Statement I don't know if this belongs here, but we are currently learning about Euler's formula in class. I was wondering if anyone knew some interesting applications of the formula. Homework Equations e^ix = cosx + isinx The Attempt at a Solution I looked on...

Because I'm transferring programs (Engineering -> CompSci), I may have three withdrawls this term. If I explain that the withdrawls are because of this program transfer, the admissions committee will most-likely understand right? I don't enjoy these courses and the courses will not be program...

I am about to start a mathematics degree and one of the textbooks I have been advised to get is Elementary Linear Algebra with Applications (10th edition) by Howard Anton & Chris Rorres. This book costs about $130 however I have found the 9th edition of the same book for far less. If anyone is...

I filled out some of my reu applications by hand rather than typing them up on the computer. My parents don't think this is acceptable. What do you guys think?

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...

Applications to some summer research opportunities are now open, but the current semester isn't over. I expect to get grades back by the end of this month. Right now, I still have a 4.0, but I fully expect to lose that this semester (I expect a B in my lab class, might also get a B in the junior...

I'm getting a head start on applying for REUs this weekend and am currently typing up my resume since one of the applications asks for one. Should I put clubs I was in during high school on the resume? A lot of what I did in high school isn't relevant to physics at all (I was heavily...

Hi everyone-- I am an international student, a sophomore currently, and for the summer I am applying for a few research programs in the States. I am trying to write the short essays for the applications nowadays, where most of them ask about "why would you like to participate in this...

I have been on the fence between computer science, chemistry, and physics as my planned area of study for quite some time now. I am fairly certain I am ready to narrow it down to physics, but now I'm wondering how I'm doing in terms of the likelihood I can get into top-notch school such as...

i just want to know few practical applications of group theory...please help!

So it's the anniversary of the buckyball today. I understand it's been a breakthrough to uncover a new form of carbon structure, but personally, I haven't followed the story during all this time. While I understand it has motivated much research and stimulated many ideas, I'm wondering if it has...

I'm debating on whether to take the October or November Physics GRE. If I take the November test, I have more time to study, but I was wondering if it would affect my chances of getting admitted to a physics grad program if all the schools got my scores a month later than they otherwise would if...

To introduce, I'm a third-year physics student at the University of Texas (Austin). As with most undergraduate physics students I've started to stress about applying to graduate school as I see friends of mine start to prepare for it. I'm actually not applying this year, but next year - I could...

Hi. I'm 21 year old and I'm currently changing colleges. (I quit Managerial Physics after 1.5 years) The field of mechatronics seems very attractive to me in regard to its curriculum and the wide range of applications they say it has. I was wondering: Does anybody here have any real-life...
