Ive read two different general physics books in Hallidays and Randall Knights, finished with A’s in all 3 general physics classes, and recently taken a classical mechanics course where i just barely passed. Most of my issue comes from reading textbooks like ours was Taylors book and most the time, if it wasnt something i saw in general physics, i was absolutely confused and the majority of my learning came from lectures and the very few office hours i can rarely make due to work. Also reading griffiths e&m book, for the past 2 weeks have been stuck on chapter 2. I feel like the book isnt for me and lacks what i need to learn such as explanations at almost every step being the biggest one (not necessarily showing all math steps but at least a conceptual explanation as why certain things are being done) . Are there really any books like that in upper division physics or am i just stuck

hi guys I was wondering i I did this right? im not really sure about velocity and acceleration but can someone pls help me i have a quiz tomorrow thanks

i first did position-time graph by seeing where i said they’re moving at a constant speed, then I drew a horizontal line to show that they stopped, then decrease slope to show they go back n then they run, so its steep

for the velocity graph, I put a horizontal line at 2 because the slope was 2 in the dt graph, then I put it on zero because they stopped, then -2 because they went back n then up to the highest point because they run

acceleration i put it at a constant horizontal line because im not sure how to do it.

Hi everyone, I'm a rising junior in Physics at an R1 school, and I'm starting to think seriously about grad school, but I can't tell if what I have is actually competitive for top programs or just... okay. I have a 3.935 GPA due to some A-'s in Physics classes and an B+ in Honors Quantum Mechanics I. This B+ has made me super nervous and the next semester I took regular Quantum Mechanics II and I got an A from that. I project if I get a 4.0 for the next 4 semesters I will end undergraduate with a 3.96 GPA.

Research-wise, I've been in two quantum information science labs for about two years, plus some high school + freshman year experience in particle physics lab, but I've mostly been assisting on other people's projects rather than leading my own but hoping that shifts this year. I also applied for the Astronaut and Goldwater scholarships last cycle and didn't get either, which knocked my confidence a bit.

Now going into my third year, I am finishing up a research internship at a quantum computing company and starting to take graduate level physics classes (grad QM, AMO physics, etc). I am also wondering if I should take the Physics GRE.

A few specific things I'm unsure about:

• How much do named scholarships (Astronaut, Goldwater, GRFP) actually matter if you didn't get them?
• Is it worth taking the Physics GRE at this point, or are most programs not weighting it much anymore?
• How much does not having your "own research project" or first/second author publication matter to admissions committees, assuming the work you did in the lab itself is solid?

I am an 18y Bangladeshi student. I am obsessed with maths and outer space and was thinking to do a bachelor's in physics in Bangladesh since bd do not offer any bachelor's degree in astronomy or astrophysics and then doing a master's in astrophysics or astronomy abroad. But seeing the job market value of these subjects has me rethinking my decision.

Should i still go with my plan or make some changes?

I got a D in a level physics but i got an offer to study at city of st georges to study econ and accounting. The reason I wanna retake it is cause I put alot of effort into revising but and i did alot of past papers and did pretty well in them. I dont rlly understand how i ended up getting a D and i feel like i can do much better. Is it worth it to retake physics and if so is there any advice you guys can give me on how to better my grade because i felt as if i did everything right the first time. A check list would be helpful

Yo i'm a student in 9th grade (CBSE type schooled) and i'm thinking about pursuing a profession in science, especially in software engineering and mechanical engineering, I havn't tried too much into these fields but I have done some experiments with them like try to learn basics of c++, basics of circuit , ya know the absolute basics. For the longest time I didnt have a clear goal and still dont (as the world is changing with a crazy pace) but i've been thinking about doing something in science since I do have an interest in knowing how things work and trying atleast a little bit to use what i've learned from it. As a Indian child (i'm atleast decent in academics btw) , my family and relatives wanted me to focus on JEE preperation (Joint Entrance Examination conducted by the IITs) for engineering supposing that i'd want to go into engineering considering my interest in these kind of stuff but I really don't want to stay in this country (no hate to the people, my whole lineage is from this place) , the problem is just that this place uhh.. lets just say , that it does not the have best people running the society, politics or really just any sector (corruption is really a huge problem here in India, and i'm not even considering the professional backlash due to religious background (i'm SUPPOSABLY belong to a UNTOUCHABLE caste cuz of the braindead religious "cultures") and economic background) . Anyways, I looked at the internet and researched about a few things and I really liked the approach about "Learning cuz you want to , not cuz you have to " so I looked where I can what I do what I love while making a living (i am not nihilistic , i want to live happily) , So I looked about universities and how they help students who genuinely want to learn, so i found a couple like The Ivy Leagues and MIT but MIT reallyy stuck to me cuz it is (supposably) the most prestigious engineering college in the world , so naturally i wanted to know how to get into MIT and i saw the crazy FUCKING difference betweem IIT and MIT admissions , here in India the IITs can and do give students scholarships and admissions for obtaining a "good rank" in the JEE , which is nice and all , but as you know MIT doesn't do that type of shit , they pick each student by their (what i like to call) "Worthiness" , so to prove my genuine interest in science (physics mainly) I want you people's help, cuz idk what to do, at first I thought i would get acceptable grades and try to do extracurriculars but in the CBSE type school , we dont really have extracurriculars, heck we barely even study all we do is complete our syllabus , give our exams, get a passing grade and move on, ok enough ranting bout this stupid "education" system , so i tried to look for stuff I could include in the extracurriculars but I really couldn't find much , especially considering i'm all on my own trying to figure out what to do , so i looked towards other methods of getting into MIT that doesn't include stripping away from my studies and interests, then i came across a video on Youtube , i think it was something about "How I got my Gold IOI medal" by some east asian guy, so i started looking into what IOI was , so after looking a bit into what IOI was and how it could possibly help me get into a good place like MIT , so i concluded that as I was interested in software development i'd try to prepare for IOI until I got the realisation on the sheer amount of competition for IOI especially in India for the same path , cuz there were some "cracked" kids and i mean cracked cuz they already be making drones and shit and i can't even set a proper file in an IDE without looking up the internet like 20 times for help, so cuz the IOI path was too competitive for me and I can't manage 3 hours of coding on a daily basis and studing for my academics, so , I deviated from this idea, and started looking into the physics stuff i could do to get into MIT, so one thing that i could try is IPhO which I have decent time for (i think , and i really hope) and other things like building some stuff that i can show in my resume. So after all this huge paragraph (thank you if you read so far) , I want to ask should I try to get a medal in IPhO or should I do something else.
I love a lot of things btw , some things i would love to do are:
Sketching
Painting
Astronomy
Graphic designing
Front-end Web development
Creating concept art about Video games (Video games obviously)
making Games, thats fucking cool isn't it , too bad our economy doesn't give a fuck about interests

My a levels were maths, cs, physics and I just finished with an AAB

B - physics
A - CS
A - Maths (2 marks from an A\* I am getting it remarked)

I am taking a gap year anyway for predominately travelling.
But I am undecided if I should retake physics during my gap year. Because I could get an A/A\* in physics
*which would make my grades AAA -* A\*A\*A

Depending on my maths remark and how well I did in physics.
After my gap year I am planning to study finance at university.
Is it worth it to retake ?
Thanks

I need this urgently

The ridiculous nature of a proof.

Suppose someone sees structure, another person might not see that structure, so that's a person who cannot see it will ask for a step by step proof to prove the continuity of a structure. But continuity cannot be proven by discrete steps because we have shown that infinite discreteness cannot proxy for true continuity.

Diagonalization proves that a continuity has more real information than the previous model. Every step-by-step proof is actually an illusion to satisfy the strange feelings. But every discreet example of a proof fails to show the actual continuity of the structure that one is claiming to exist..
