how can I go about finding the surface absorptance of a material if I'm not given the radiant emittance of the non- black body?

I want to become an astrophysicist, but I don't have enough money to attend a 4-year college once I graduate (may 2024) so my dad said that I should plan on going to a community college and then transfering to a university. Will I still be able to become a physicist if I go to community...

https://www.physicsforums.com/threads/regret-induced-jealousy-how-to-deal-with-this.1011135/#post-6586239 I made a post this few days ago but I believe this is different than that post. How do I get over this? I wasted time trying to make online income, creating blogs. I didn't realize full...

Is it possible for me to do cosmology and quantum mechanics as a joint degree at uni? If so where and does it cost extra? I’ve been wondering for a whole and I’m not sure where to look.

Hey! So, I'm starting university this year, going in for a BSc. Physics and Astronomy, and one of my first year courses is computer science for the physical sciences. I do have some coding experience but it's very minimal with html and and Visual Basic, not very good languages. I did well in...

The classes include: Electricity and Magnetism 2, Intro Modern Physics, Intro Theoretical Physics, Optics Lab, Intro to Solid State Physics. I will have a good amount of experience in E&M as well as Theoretical Physics. This will be for my second semester of 3rd year going for a B.S. in physics...

Hi! So, I made into all the unis I applied to, for astrophysics and astronomy, ended up choosing the one not as well ranked only because I made it into their concurrent education program with astrophysics, chose a professional program over a Bsc here. I'm scared, I love astronomy and physics but...

I am very clueless when it comes to prepping for university and things like that, and as a grade 11 going into grade 12 soon, I unfortunately have to figure it out one day or another. So, I have a few quick questions, would I need Physics 30 or Calculus/Math 31 in order to become a family...

I'm currently in year 12 (studying IB with hl physics, maths and chemistry) in the UK and am starting to look at uni courses. For a few years now I have been absolutely fascinated by the particle physics/quantum side of physics. At the movement I would love to work in research in this sort of...

Hello everyone. I have a weird question regarding the calculation of free energy changes in a multi-step mechanism. Now, if you have a bunch of calculated free energies in gas phase at 1 atm (say, from an electronic structure program) and you want to model in solvent, you need to get them in a...

Hey guys, I am currently working on a uni MATLAB group project for blast radius, thermal radius etc. Apparently these formula are the best possible to use: r_thermal = Y^0.41 * constant_th r_blast = Y^0.33 * constant_bl r_radiation = Y^0.19 * constant_rad But can anybody tell me what...

Let's start with a vacuum, I will write |0000...> as |0>. $$ \psi^+ (x) |0\rangle = \sum_k e^{-ikx} a^+ (k) |0\rangle $$ Qns: What happens if you superpose/add up state vectors corresponding to a particle of momentum k and you add up with coefficient e-ikx? $$ \sum_k e^{-ikx} a^+ (k) |0\rangle...

Hi. Anyone here doing the distance learning hnc at teesside uni.

Figure (a) shows a narrow charged solid cylinder that is coaxial with a larger charged cylindrical shell. Both are nonconducting and thin and have uniform surface charge densities on their outer surfaces. Figure (b) gives the radial component E of the electric field versus radial distance r from...

In high school, everyone and I tried to get admission into the best college we could. But then I realized that this doesn't make much sense. For example, if someone got into a reach school, and did so by luck (their GPA and SAT is lower than the average admitted student there), then when they...

Hi everyone, So I'm currently in the middle of my summer holiday (waiting for A Level results) and I'm getting pretty bored of not knowing what to do. (I have contacted some charities for volunteer work but still waiting to hear, anyway that's beside the point) At A Level I studied Maths (Core...

I'm asking because I'm slow when it comes to mathematics in Physics exams , and I was wondering if Universities cater for people who are slow thinkers by making Physics exams longer than high school exams?

Hi all, I have a very basic question regarding the topic of stress.While deriving the equations of equilibrium for a plane element,there is a concept called incremental stress.That is,if stress in the x direction for one face is σx the stress in the opposite face is σx + (δσx/δx)*dx. Where the...

I am an electrical engineering student. My university is not that great and the EE program is not that great either, I don't even like the subject. . I just took the best opportunity I got in my country.. Anyways, I wish to pursue higher studies abroad after graduation and I will definitely...

Is there always the same "amount" of spacetime curvature in the uni.? Universe is what I meant by uni. Okay, if matter and energy cannot be created or destroyed, and since they are what causes spacetime to curve, does that mean there will always be the same amount of spacetime curvature...

Doing badly in high school but want to go to uni for science :( Well, maybe I'm not doing TOO badly. You see, I am in the IB program, which is a rigirous high school program designed to simulate university. In this program, our final marks are basically determined by our exams, since our exams...

At my university, they calculate gpa without the +- system. So if i got 90s (A-) in all of my classes i would have a 4.0. In general, when applying to grad school, will they look at the gpa my university says i have or will some of them calculate it to be a 3.6?

I think for the first time in my life I am feeling really exhausted and slightly depressed. I'm studying computer science and I'm in my second year and I just feel completely exhausted and constantely tired. I am really not enjoying my subjects and it just feels like a chore to learn...
