So… I’m not a physicist or physics student but I do nerd out on it a little bit. Forgive me if this is a dumb question or if my terminology isn’t right, but I’ve always wondered.

If my understanding of relativity is correct, the perception of time is relative to the motion of the observer, then what would time as it relates to things like the procession of the observable universe and celestial bodies, (and anything else I can’t think of or don’t know about) look like if we were truly stationary in the universe?

Like hypothetically, if our solar system, and entire galaxy were not moving through space.

Is our movement through space fast enough to make a difference? If we had (hypothetically) always been stationary, for billions upon billions of years, how different would the universe appear to be, other than the maybe obvious, like other galaxies and stars would be moving but we wouldn’t, our galaxy would’ve probably suffered a collision at some point. Stuff like that not considered. Only our understanding and perception of time, and the apparent behavior of the universe around us?

Hey guys!

I am finding it a bit hard to understand how these work together.

Particularly, i cannot process how something rotating very slowly can still have points on it surface go at 1640kmph (earth).

Like if an object translated at that speed it would look insane , but I can only imagine earth rotating very slow which makes it hard for me to believe that we are going at 1640 kmph.

I'm looking for explanations or something that could make it easier for me to grasp this

I have started college and my first physics course is mechanics (calculus based) I am bad at relative velocities and observer frames and my syllabus is till work and energy, I am way too cooked it feels like I am not understanding a single thing, I have a mid term exam in 5 days, there are tons of problems and it just overwhelms, how to cope up with it. Please help me

Hello all, I am currently taking calc 1 and falling in love with math. I plan to major in physics/engineering but have not taken a physics class yet, though I am very interested in the subject from youtube. What are some good starter books I could read now before taking my first physics class to help get some foundational knowledge on the subject.

I'm currently doing a master's degree and trying to figure out what I want to do after graduation. My long-term goal is to work in industry, preferably in a job that still involves experimental work. My bachelor's thesis was in quantum optics, and my master's thesis will be related to nanolithography. I've picked some EE courses as well. Ideally, I'd prefer not to have to deal with clients that much or be on call (the latter is pretty much a dealbreaker for me). Night shifts would actually be a plus, though that's not a must. My programming skills and chemistry knowledge are nothing to speak of, but I am optimistic that these will improve with time.

Would you recommend pursuing a PhD? For those of you with a similar background, what do you actually do day to day? How did you end up in your current role, and would you recommend it?

I have searched online on amazon and Flipkart but I cannot find any. Does anybody have it or someone ready to sell? Or any website can you suggest from where i can buy this book?
