I will be taking intermediate mechanics next semester, and am a bit concerned about potential gaps in my mathematical knowledge. Long story short, I used to be a physics major, switched to electrical engineering, and then decided to double major after a semester in EE. The issue is that, as a...
Okay so I recently found out that in official canon, the Galactic Republic of Star Wars was founded 25,000 years before the first original movie. Hyperdrives were presumably invented around 25,000 BBY. By the time of the Phantom Menace which is in the year 32 BBY, Technology has stayed basically...
Hello there, do you guys have recommendations for math textbooks that i should have?
The math is of course related to physics, I mean the maths that a physics student must know.
Hello,
TL;DR: Could it be practical to leave a PhD in earth science in order to earn a BS in math (starting at the upper division level) if I'm tired of having a spotty math foundation and want to be able to learn anything?
I've been on a slow, wandering path towards a vaguely defined "career...
Hypothetical: Approximately how far from earth would a star the size of the sun have to be for an object the size of a quantum particle to cause a total eclipse of that star when orbiting the earth at a distance equal to that of earth to the center fro the moon?
This might be total nonsense, but the thought popped into my head while I was trying to get to sleep, so I thought I see if I could find any advanced help with the following hypothetical:
If light were instantaneous, how far from earth would the sun have to be to cause a quark orbiting in place...
Hello,
So, I'm looking for some advice from people here who have experience studying physics outside of an academic program. Recently, I've started Griffiths E&M. Although it hasn't been long, I've been having an absolute blast: like, heart-fluttering, "helping me with suicidal depression"...
I am currently in my second year of studying a bachelor in physics and applied maths. My aim is to one day do research in physics. I am particularly interested in subjects such as gauge theories, AdS/CFT and gravity. My question is whether it would be more beneficial to switch from studying...
Homework Statement: Hallo. Can somebody explain to me what's the importance-use of unit vector in the below (second) equation? Why isn't the first equation just enough to describe r? What's the reason for unit vector to even exist?
Homework Equations: in the photos
Homework Statement: what is the mathematical explanation for fresnel lenses
Homework Equations: No equations were provided
I'm gonna post a link to one article I found that I think has the answer, but I couldn't understand because of my lack of knowledge in physics and math...
Is there any theory in physics that can be modelled in any type of space (Hilbert space, Euclidean, Non-Euclidean...etc)? And if yes, could that theory also contain/be compatible with all types of (physical) symmetries?
I am a beginner and I know a little bit of Math.
Can anyone tell me what concepts in Math do I need to know to see one ball jumping in space?
I need names of the concepts which lets me realize this Jumping Ball.
Thanks.
Throughout a degree as a physics major, you take a bunch of math courses, and it's safe to say that you should have a good understanding of all the calculus and algebra courses. But what math subject/specific course should I master at a spiritual level? Especially ones that are needed for...
Hello everyone, since recommendation letters are usually important when applying for graduate studies, I'd like to ask the following:
What do you guys think of the statement
'The best way to maximize the "goodnes" of your recommendation letter is by not caring about it'
?
I guess it's...

So I decided to go for two degrees instead of one so the goal is two associate degrees.One in Physics and the other in Mathematics any one have any advice on the this math heavy course of action I’ have set for myself.
Hi, I have this equation about Rossler system, describe as Eq. 1. Given that the chaotic behavior of the system for parameter values a=b=0.2 and c=5.7.
How can I calculate the chaotic sequence for this equation below.

Is it because it would depend on your reference frame?
What are the conditions for applicability of u-substitution, i.e. when does it not work? Note that I'm not asking when is it a bad idea (that won't get you any closer to evaluating the integral), but are there any conditions that cause u-sub to yield wrong answers?
I started running into what I...
Considering one is taking all the required math courses for a typical physics degree, what math electives are most crucial to the field of cosmology/theoretical astrophysics?
Also, is it true that mathematical modeling courses(discrete and dynamical modeling across physics) are more important to...
I am a high school student who is planning to start Young and Freedman’s University Physics out of personal interest. However, I am not sure what level of math is required for the book.
I haven’t learnt Calculus yet, so I’m planning to study Strang’s Calculus alongside Young’s University...
I’ll be taking the year long physics sequence at my college this fall and I want to know what specific math topics I should master, so that I can conquer my first year of physics. I’m planning to brush-up on any necessary topics from algebra, through precalc, and including calc 1. It’s an honors...
I have spent the past few months incredibly conflicted. I just finished my freshman year of undergrad (at a 4-year American university) and I have discovered Biophysics, a field which I really want to pursue. However, I still love math and want to continue with my Applied Math major. I'm afraid...
Hi! I just started high school and have developed a passion for cosmology and astrophysics. I would like to know if I really need to be very good at physics and mathematics (and if there is more that I need to be good at) and where do i find a job (spaces like N.A.S.A., SpaceX etc).
Thanks for help!
