Degree Definition and 1000 Threads

Hey guys so I'm enrolled to start a physics major this coming semester but have been out of school since 2009 (im 24 now) and haven't done much if any related math or physics study since. Had always been quite good at maths and physics in high school but worried that i will have forgotten a lot...

Can one teach college level Physics classes with a CAMPEP accredited Master's or Ph.D. in medical physics? Do most departments look for pure physics graduates or is medical physics acceptable?

Hey, I'm looking for a bit of advice with regards to applying for a PhD program in Europe. As a bit of background: I graduated from Durham University in 2013 with a 1st class MPhys in Theoretical Physics. My thesis (which contributed to half of the grading in the 4th, masters year) was focused...

Hey! :oI want to calculate the degree $[\mathbb{Q}[\sqrt{3}, \rho] :\mathbb{Q}]$. It holds that $$[\mathbb{Q}[\sqrt{3}, \rho] :\mathbb{Q}]=[\mathbb{Q}[\sqrt{3}, \rho] :\mathbb{Q}[\sqrt{3}][\mathbb{Q}[\sqrt{3}] :\mathbb{Q}]=[\mathbb{Q}[\sqrt{3}, \rho] :\mathbb{Q}[\sqrt{3}]]\cdot 2$$ and...

Hey! :o Let $E_1, E_2$ be extensions of the field $F$, that are contained in a bigger field, so it makes sense to consider the field $E_1E_2$. Without using the proposition: $F \leq K \leq E \Rightarrow \text{tr.deg}(E/F) = \text{tr.deg}(E/K) + \text{tr.deg}(K/F)$ I want to show that...

I am a sophomore in High School, and I am considering getting a PhD in astrophysics. Is a PhD worth it? Also, what job opportunities will be available to me? Thanks for any feedback : )

So I was talking to one of my friends who is a huge programmer, and he said that you don't even need a computer science degree to work in software. He said that companies would rather teach a mechanical engineer how to program, than a computer science grad how to problem solve, and that out of...

I am currently doing Bachelors in Economics however I have always wanted to pursue astrophysics and all. So like can I in the future with a good enough GRE score do a graduate degree in Physics? And also what would you suggest me to study to know undergrad education of Physics? I really love...

Hello, I'm currently a junior in high school and I've been thinking about what I want to do for a while now. Since my freshman year I've wanted to go into astrophysics but, as you all know, that is far from uncommon. I plan on primarily pursuing astrophysics, but I don't want to graduate without...

I was wondering if one could earn a Physics degree while on active duty. I was thinking about joining the Air Force.

Hi i was thinking about how to calculate the temperature lost by Degree Celsius per minute and was wondering if you had the surface area of the object, its initial temperature, a constant flow rate of air around the object and probably also need some coefficient of heat loss based on the...

Hello everyone. I'm approaching the end of my physics graduation and must start to think about what to do next. I'm working in a project with a professor in the university about stellar sctructure and it captivated me. Now i don't know if i take the specialization in nuclear physics or...

I apologize for asking a question that has been asked trillions of times. I've searched the PF for many links, however, I didn't find something good. Let's suppose, a person named Arthur. This guy is a 12th grade student. He is able to do Halliday Resnick Walker. He has slight background in...

If ##M^{2} \subset \mathbb{R}^{3}## is a surface with given normal field, we define the Gauss (normal) map $$n:M^{2} \rightarrow \text{unit sphere}\ S^{2}$$ by $$n(p) = \textbf{N}(p), \qquad \text{the unit normal to $M$ at $p$}.$$...

I am a physics student from Spain and hopefully I will be finishing my degree in physics (4y) by next June. I am trying to decide on a Master's program to study but I am finding very difficult to decide since there are so many oportunities and so diverse specially when looking for programs...

Homework Statement If Char(K) = 0 and [L:K]=2, is L:K a galois extension? Homework EquationsThe Attempt at a Solution My gut is saying yes because if [L:K]=2 then it seems that any polynomial in K[x] with a root in L should split in L[x]. Something about how some hypothetical minimal...

Hi, I'm just 2 semesters short of graduating and I'm currently in specialization in physics program (Bsc). Over the years I have taken more math courses than physics (due to interest) and as a result, I can change my program to double major in physics and math. From employability point of view...

Homework Statement Find the roots of x^4 - 6x^2 - 2 Homework EquationsThe Attempt at a Solution So my first observation is that this polynomial is irreducible by Eisenstein criterion with p=2. If I substitute y=x^2 then this polynomial becomes a quadratic, and I can apply the quadratic...

I am really interested in physics, and have a knack for it (am currently in my second year of physics at college, so I think I can honestly match myself up with other physics majors), but am not a savant or anything. I would love to push through and finish the degree, but the degree doesn't seem...

Hi! this community seems like the exact place to to find the answers I am chasing after. I want to earn a degree in physics and pursue one of the vast array of different fields that are available. I am what's called the black sheep of the family, as both my sisters have masters and a PHD. I...

I have the following question: Is there a basis for the vector space of polynomials of degree 2 or less consisting of three polynomial vectors ##\{ p_1, p_2, p_3 \}##, where none is a polynomial of degree 1? We know that the standard basis for the vector space is ##\{1, t, t^2\}##. However...

I wanted to know which one was better for finding jobs and salary wise or are both pretty much the same. Computer Science or Software Engineering degree? Also would anyone recommend getting the degree online?

So say that I have the quadratic equation ##x^2 - 2x +1 = 0##. If I multiply each side by ##x##, a valid operation, I get the new equation ##x^3 - 2x^2 + x = 0##, which has a different solution set as the first, namely ##\left\{ {0, 1}\right\}##. If I make the substitution ##x^2 = 2x -1 = 0##...

Up until this past summer, I thought I was going to go to Physics grad school following my undergraduate study. I worked at an REU program at UC Davis this summer, and decided that physics was not the route for me. Now I am trying to decide to which engineering discipline I should apply. I have...
