What exactly is the difference between the two? And does it matter which is chosen if the person intends on getting a BS degree?

Hi dear all Please explain to a stupid dummy a very simple thing. Take an a photon in 1+3 dimensions. How DOF it has? We all know that 2. How we calculate it? a) 1) We have a spin 1 particle that should have 2s+1=3 spin state. So DOF=3. 2) We have 4 Aμ guys. One is out because of gauge...

Okay yes . I am a noob. I want to know what all courses are out there that are related to physics ...classical non classical anything related to physics that I can take up in college ?

Hello people, I am a grade 11 student in Ontario. I am currently facing a dilemma. Recently, I started thinking about my career, seeing as how I apply to university next year. I was considering options and I stopped to think; I want to do something I enjoy. I want a job that I don't see as...

I am doing a projectile motion problem with my own results, and the unknown's of initial velocity and time. It is at 0 degrees, which I thought would mean I could find the vertical down of the projectile (where at an angle you find the vertical up and down because it goes up first). I have tried...

OK I have a right angled triangle and one angle is 1/8 pi. So I know two angles then, 90 degrees and 1/8 pi. I also know the hypotenuse has a length 5 units. I am required to find the angle remaining in radians. The problem I have is that although I can do conversions on the calculator they...

Hi I am struggling with a problem here. I have 6 data points, and I have found the solution of a model which I believe should describe the behavior of the data. Now I am trying to fit the parameters of the solution to the 6 data points. The model contains 5 degrees of freedom, all of which...

Homework Statement Okay, this is a projectile motion problem(No Drag) where a rock is thrown as 35m/s at an angle of 48 degrees. The question that I am struggling with is: "Find where and when the trajectory angle is 10 degrees?" Homework Equations The Equation that my teacher was used...

Hey guys, I hope you can help me with this question. I'm currently studying engineering. When I applied to my college i told them i want to to electrical computer engineering but when I look at my degree online it says electrical engineering. So my question is, is there any difference between...

This is about applying from a British undergraduate to an American graduate. How is a British degree viewed by an American university? Is a British applicant with a 1st Class Degree viewed just as favorably as an American candidate with GPA 4.0? Is there anything that goes in favor of the...

I'm starting on lagrangian mechanics and is a little puzzled by the use of generalized coordinates. Shortly, what is a degree of freedom? And what I find harder to understand, why is it that a holonomic constraint allows you to remove a degree of freedom? Consider for instance two particles...

Do I need the special "areospace" or "aeronautic" degrees? I've been thinking about going to a local college that has a very good engineering and physics department and was wondering if I needed the specific areospace or aeronautic engeneering titles or do I just need mechanical engineering or...

Hi, If you are sick of me already, I don't blame you. Ok so here is the update. I just got fired from my job for a code of conduct violation. I have an undergrade business degree with a focus on economics. Basically, I like banking and finance and especially stock trading, but I hate...

I am currently attending IUPUI for a double major in Pure Mathematics and Computer & Information Science with a double minor in German and Physics. Overall this will take me 4 1/2 years and give me $38,000-$45,000 of debt. 1. I am wondering, which masters degree should I go for first? Math or...

I'm going to be a freshman in college this year, and I really want to go into astrophysics or particle physics. At this point, I really want to work at the LHC when I get out of school. I know I may change my mind along the way, but could you please give me advice on any specific courses to take...

So, recently I have graduated from a community college, I have received two different A.S. degrees. One is for math, and the other is for science. I am continuing my studies with more math, more science, and a computer programming. Since computers and science go really well together, I have...

How can I calculate degrees of freedom of a rank (o,3) tensor, Aabc, that is mixed symmetry and antisymmetric in the first 2 indices? By mixed symmetry I mean this: Aabc+Acab+Abca=0.

In the case where you have a photonic clock bouncing a photon between 2 mirrors, if the mirrors are alligned on the vertical axis, bouncing the photon up and down and the overall clock traveling along the horizontal axis, then the whole thing makes sense to me. However, if you were to rotate the...

angles -- why in radians instead of in degrees? greetings, why all the angle in electrical is represented in radian instead in degree? advanced thanks

Hey everyone, I'm beginning my physics major in the fall, but my situation is a little odd. I have an AA in history (because I had to work full-time through my degree and it was available entirely online at my school). Now that I'm able to finally study what I want, my #1 plan is to graduate...

I was reading through a book on statistical physics when i came across this sentence: "An Einstein solid has two degrees of freedom for every oscillator." How is this possible? I picture an oscillator (ex. mass on spring) to move only in one dimension, thus one degree of freedom. Where does...

I had three questions that had to do with spacetime, digital physics, and the holographic principle: 1. Why are there dimensions in space? 2. Why isn't there just some sort of information matrix as suggested in digital physics? 3. How do these two ideas work with the holographic principle?

I have a list of bearings that I want to convert. The normal degrees circle is oriented with 0 to 360 going counter clockwise. I have degrees calculations that require this. I have a set of data from bearings from an aircraft where I need to convert those bearings to normal degrees bearings. As...

So if we have an extension of E of F, then we can consider E as a vector space over F. The dimension of this space is the degree of the field extension, I think most people use [E:F]. This is correct in most people's books, right? Defining \omega = cos (2\pi /7) + i sin (2\pi / 7) Why...

My dilemna is not lack of knowing what I want to do, it's knowing too much that I want to do. I'm very passionate about both Electronic Engineering, and Computer Science. I'm intending to apply for both at different universities (because I'd love to study either of them, and what I've applied...

Hi, A symmetric 4x4 matrix has 10 independent components. Let's say that matrix describes graviton h_mu_nu. In general I can bring any symmetric matrix to diagonal form, so if can and I bring my h_mu_nu matrix to diagonal form where it has only 4 independent components ... than what happens...

Consider one particle traveling at a relativistic velocity in 3-space. Then the configuration space of the system consisting of that one particle would have 3 degrees of freedom – 1 particle times 3 dimensions. Because of its high energy, the particle decays into, say, 2 particles. Now the...

Homework Statement Homework Equations The Attempt at a Solution I'm confused actually how to go about this. Sounds very simple, but when i do what they suggest, 'first, find the variance of (n-1)s2/σ2 i get larger variances rather than smaller, which makes no sense. should...

Hi. Here is some (more or less) relevant information: So I'm majoring in Philosophy and Logic, and I recently found out that if I do about an extra year of undergrad work, I can get a second bachelor's degree (In Mathmatics!) So I'm thinking: Since graduate school in Philosophy is pretty hard...

Recently did an exercise calculating the theoretic heat capacity of a metal. In the solutions manual they put the degrees of freedom f=6. Why is that? I know that a rigid body has 6 degrees of freedom but does that apply to each atom in the crystal?

What I want to end up doing is working with electronics that interface with the brain, and work to fix disabilities and issues in functionality, as well as possible devices that can read the brain etc etc. What is the best undergrad and grad degrees to pursue for this? As of now I am going EE at...
