Thanks a whole lot, this seems very useful! Can't thank you enough :)

I kinda understand it, I've seen some videos on Khanacademy about divergence and curl (don't remember which one that triangle symbol is referring to ) and partial derivatives, but I haven't seen them used in physics. Would this PDF be about the classical mechanics you are referring to...

I tried looking at lagrangian mechanics but I got lost at the introduction :P What are the knowledge requirements of lagrangian mechanics?

For classical mechanics, I've learned about: Forces, pressure, Newtons laws, momentum Energy (kinetic and potential) Thermodynamics Electricity and Magnetism Optics Waves (sound, spring and light - although light is more about quantum mechanics?)

I know things up to basic calculus: stuff like derivates, integrals, rotating integrals, differential equations. Trigonometry, if that counts as calculus (I live in sweden so I don't exactly know what americans consider calculus) Just a question: do Lagrangian or Hamiltonian mechanics play a...

I am a high school student. I looked up Special relativity and grasped it pretty easily, without needing to learn any new math. But when I tried to read about general relativity, I was immediately confused by all the math, equations and notation. My problem is that I have no idea where to...

I'm sensing that I have to go and understand how an accelerometer works more deeply... :P Thanks for the help, I will check out the accelerometer before I ask any more questions!

I mean, if you are standing still in the center of the accelerating frame, the inertial frame appears to accelerating (like standing on the train, looking at the person on the station platform). But from the point of view of the inertial frame, the accelerating frame appears to be, well...

I'm probably not being fully clear :P I'm kind of thinking along the lines of "How do we sense acceleration at all?"

Suppose we have two frames of reference, with one being accelerated (not inertial). This could be you standing on the platform of a train station as a train in front of you is starting. From the train's point of view, you are accelerating, but one obviously knows that it is actually the train...
