    Programs Deciding between a math and physics major

    Ok. Just for the sake of completion I think I should respond, but I think I might have some sense as to what I'm going to do (you were definitely helpful though). I do realize that there was some contradiction related to the fact that I had stressed applicability and yet showed interest in...

    Programs Deciding between a math and physics major

    Okay. So I’m a rising Junior and in a bit of a dilemma. I have to pick a major and right now I’m trying to decide between math and physics (hard to do both because I’m taking a fair number of computer science, economics, mechanical engineering courses et cetera). There are things that I like and...

    Schools Choice for particle physics between LAC and university

    I haven't edited this as much as I might to make it pretty, but it gets my general opinion across. No one has responded yet so I'm just going to go for it. Unfortunately I am only an undergraduate so it is harder for me to comment on the PhD side of the equation; however I can talk about how I...

    Java Defining variables in the context of implicit functions in java

    I found a way around the issue since I'm allowed to approximate. The software you mentioned is definitely interesting and I think I will take a look at it as I begin my next project. Thanks!

    Java Defining variables in the context of implicit functions in java

    Sorry for the disturbance, So I have been looking (without success) for a way to define a variable within an implicit function in Java. What I really mean by this is I have the equation: In this function my program will give me all of the values except for px. I have tried rearranging the...

    Is My Rocket Mass Distribution Formula Incorrect?

    Sorry for the trouble. Actually my assignment provider changed the dry mass fraction because he realized that the parameters we were given were not feasible. Everything is resolved now. I hope this thread did not cause any difficulties. Thanks for the time.

    Is My Rocket Mass Distribution Formula Incorrect?

    Note: I have noted that one of the formulas I have provided does not show up on my webpage in preview mode and so have also made it as an attachment. Quick summary: I have found two different websites that offer the equation that I am looking for in different forms, but I am starting to think...

    Using ampere's law for a circular loop

    Ok. (Just confirming) $$\vec{B}\cdot\vec{dl}$$ will equal zero (because we're taking a dot product of perpendicular vectors) but this does not mean B equals zero. Ideally we want to choose a loop where B is in the same direction as dl such that we can just divide by the distance over which the...

    Using ampere's law for a circular loop

    I think I get it. Since the B fields may be opposite at some points if I integrate the B fields over the surface I will get zero. But if I'm to find a specific B field at a location since B is not a constant function (it flips signs) I can't just divide by 2* pi * r and get 0. This is because...

    Using ampere's law for a circular loop

    Homework Statement Sorry to bother you guys, I've heard that Ampere's Law is either ineffective for calculating the B field due to a circular loop or needs some modification (I wasn't sure which). I'm trying to figure out why this doesn't work so I can get a better understanding of Ampere's...

    Conservation of Energy for Parallel Wires

    So this video is a demonstration of induced current due to change in magnetic flux I believe. Are you saying that the law that this relates to will get me to the derivation of where the new potential energy by closing Circuit 1 comes from? Totally possible; just want to check. I believe my...

    (Fundamentally) Understanding Circuit Boards

    I was hoping not to bump this but I do want to thank you for the info. There is a lot of stuff here for me to look through. Thanks :).

    Conservation of Energy for Parallel Wires

    Homework Statement So I'm trying to prove to myself that energy is conserved in the case of magnetism. Here is the set up that I'm using to get that understanding (attached image). Just to be clear the arrows represent the current lines and I am calculating a gain in PE because if I release...

    (Fundamentally) Understanding Circuit Boards

    Just so I'm clear on this, the difference between system functionality and implementing specific functions is that (this is a little bit of a guess; I hope I didn't miss an important part of your text): i) System functionality is more macro. Instead of figuring out how each function of the...
