Hello everyone. Most likely, I will soon be transferring to NJIT and majoring in applied physics. NJIT offers double major programs in applied physics and either applied math or computer science. If I had to pick one out of pure interest, I would probably go with applied math; however, computer...

The best instate college in my state for mathematics is Georgia Tech. However, it does not have a pure mathematics degree. Can I still go to grad school for pure mathematics as an applied math major? Will it prepare me for pure mathematics?

Why is it: $$ \langle A \rangle = \int dV ~ \psi^* (\hat{A} \psi) $$ As opposed to: $$ \langle A \rangle = \int dV ~ (\hat{A} \psi^*) (\hat{A} \psi) $$ The op can substantially change the wf, so it would seem to make more mathematical sense (at least from a linear algebra pov) to...

Due to personal life issues and limitations, I've been seeking other options for my B.S. and came upon Applied Mathematics. What I've been on the fence about for a while now has been which Engineering degree to pursue be it Material Science, Mechanical, or Aerospace. However, it has been...

Could somebody please tell me if we can apply young modulus theory to a slinky spring, or can only be applied to a rod when strenched?If possible to apply to the slinky spring, how can we calculate the elasticity of that slinky spring?by the way what is the process by which slinky springs are...

This is a problem I've been working on... I did some things wrong, and syntactically incorrectly, and just messy. Could you help me out? Tell me how I can write this more syntactically correctly, and cleanly, please? Also, I realize that some might believe this would be more appropriately put...

Hi, Can anyone explain what would be the maximum shear force experienced by a rod if equal and opposite torques (T) were applied at each end? In comparison to a rod that was fixed at one end and had a torque T applied at the other end would the maximum shear experienced by the rod be...

Hello guys, Check out this book: https://www.amazon.com/dp/0393063410/?tag=pfamazon01-20 Do you any other good book on the subject?

I think I'm missing something really simple here due to being out of school for a while: In a free body diagram, if I am trying to take the sum of torques about point 1, how should I deal with an applied torque at point 2? See attached sketch

Explain how and why the weak signal (potential) applied to the gate G modifies (or modulates) the strong (current) between the source S and the drain D in the JFET . In particular you must indicate what happens to the depletion layer and the conducting channel when a. (10) Positive potential...

I'm planning on doing a BSc in applied physics next year, but my real passion has always been history and archeology. The reason I chose for applied physics and not history or archeology is because the odds of getting a good job after the study are much greater. Now I was wondering, what are...

Hi all. I'm trying to become acquainted with thermal dynamics. I thought I had a fairly good handle on the idea gas law, PV=nRT, or PV=mRT, but I came across a problem involving the throttling of an idea gas, and the solution was totally not what I expected. Referring to picture where gas...

I was wondering what are the main types of "applied math" I could choose to study in grad school and how I can know which one I would enjoy most? Math Classes I loved were: linear algebra, number theory, intro to real analysis, discrete math, intro to abstract alg Classes I disliked...

If a force is applied to a box, and the box is not displaced, no work is done on the box, right? But to apply the force, don't you use up calories which is a unit of energy?

Hi everyone, I signed up just to ask you guys a quick question, as most of you will know infinitely more than I do on this subject. I'm not an astrophysicist, I have a strong interest in the universe and cosmology, but it's more of a hobby for me than a central focus, so I apologise in...

I have received some admissions decisions from the graduate programs that I have applied to, and I am stuck with a tough decision to make. I am hoping to hear from those who may have found themselves in a similar situation or someone who may have relevant industry experience who can shed some...

Suppose you a have superconducting loop connected to a 9V battery. What is the current through it? With a resistance of 0Ω, V = IR gives ∞. I don't think that can be right... If it were, V=\frac{I}{nAe} would give an infinite velocity... Does that equation even apply to superconductors?

Here's my current story: I'm at CC right now double majoring in Physics and Engineering Science. When I transfer (Rutgers) I will continue to Mechanical Engineering and plan to continue Physics as a minor. I am highly interested in Mech. Engineering and I love physics, I would major in...

I'm a sophomore physics major and will be choosing classes for next semester in a couple of weeks. I was planning on taking mathematical methods because I've often heard that it makes a big difference going into the upper level classes but unfortunately, it isn't being offered next year. It has...

Recently I've sent out a few resumes + cover letters to companies that have openings listed on their web sites. These are small-ish local companies, with <200 employees. The first couple, I got nothing in response - nothing. So this last one, after a week or so with no response, I sent a...

Its been many years since i studied mechanics at school and I need to know how to calculate the force applied to a vice jaw by turning the vice handle .i am guessing that it could be worked out by measuring the length oF the threaded bar and also the length from the pivot on the handle but...

I'm confused over this because generally I'm told that if the voltage increases then so does current and this satisfies the equation:V=IR because I=V/R increasing the top of the fraction should mean that the current increases but this contradicts the equation:P=IV be=P/cause this time I=P/V and...
