Homework Statement This is not a homework problem, I'm working through griffiths Electrodynamics on my own. Homework Equations when there is an emf source, since electrosatic fields integrate to zero around a loop The Attempt at a Solution The solution claims that since the integral of f...

This is a Bamboo Copter: https://en.wikipedia.org/wiki/Bamboo-copter So the key to building a stable one is that the "rod" part spun by the hand has to be heavy. However, a uniform force field cannot exert a torque on a rigid body. By elimination, I assume that external forces stabilize the...

I set a small project for myself to design a controller for a rocket, which moves a mass around to shift the center of mass, in order to steer a rocket. The picture shows a simplified model of a rocket plus a movable mass. , shown is a rod for the rocket, and a mass for the controller. there...

So, I'm investigating a certain way of steering a rocket in space for my first undergraduate research project. Essentially, the idea is to control the location of some mass located on a horizontal track perpendicular to a rocket, so that when the mass is moved, the center of mass of the rocket...

I've been reading about self teaching physics (mainly because the college curriculum is too slow to get me to any meaningful level of understanding at the end of four years), and an issue was brought up about lack of intuition in quantum mechanics/GR, and depending too much on the math. I was...

Wow necroing a two eyar post. I was just asking why it is not a "logical" next step to assume that the coulomb or gtavitational forces add linearly just from an experiment with two particles. Ie, if you bring in one charge from infinity, you find some sort of 1/r^2 dependenced but you know...

thanks for the encouraging words. As I am. I am taking Signals and Systems this quarter but the professor is somewhat mediocre, so I'm watching the series by Oppenheim while working along that textbook instead. It's rather unfortunate, however, that my school splits the topic into continuous...

I will keep this in mind when the time comes. And as I'm looking for research. Thanks.

Ah yes, my faculty mentor said I'd be interested in such a major, but turns out my school doesn't offer the major. I just got to make do with what I have haha.

I meant that more as a offhanded joke. I'm taking a four class quarter right now and it seems fine. I have enough time left for clubs, and ballroom dancing on the weekends. I have a spreadsheet for tracking classes that I plan to take, and it already includes the EE classes that I don't need to...

If you meant this figuratively, then I could complain about how I have no time left after studying. Logistically, at UCLA to complete an EE degree you have to take 4 classes per quarter (3 classes for 2 quarters). I came in with 5 math classes fulfilled, taking two physics labs over the summer...

Clarification: I'm completing my EE major in four years, I just have a rather large amount of left over class space, with which i can either choose to rush to grad school, or taking additional classes. 1) regarding physics: I've found that being good in physics translates to mathematical...

Feel free to skip to bottom to read the questions. Below is some relevant background. I'm currently an undergraduate freshman in EE. I find physics exciting (not sure if I like it because I'm good at it, or I'm good at it because I like it), so I'll be taking most of the courses that a physics...

Thanks for all the replies, I'll be taking optics/electrodynamics/thermodynamics courses in the three coming quarters, I'll set a reminder to come back to this in a year :D. I do have a general idea of what both of you are saying, but it seems like I'd appreciate many of the basic ideas you are...

I never really had a good idea of the mechanisms behind color. why we feel heat, what determines the color of fire, etc. So, today I sat down and did some research. I want to explain the processes here to make sure I got it completely right: For complete combustion of most hydrocarbons (blue...
