At which point do you start feeling like a real physicist? Thanks for the article, it is brilliant. However a troubling thought that sometimes bothers me is that at which point do you feel like you're a true physicist who can do some stuff? right now I'm learning undergrad physics full speed...

I got stuck going over the derivation of fictitious forces in rotating frames. see specifically http://en.wikipedia.org/wiki/Rotating_reference_frame#Time_derivatives_in_the_two_frames this page to see the proof I'm talking about (sorry i'd love to be able to explain it by myself but...

seems to be a "paradox" in galilean relativity Hello I'm having a little bit of trouble with so-called rest frames. I will distinguish two cases. consider frame S, and a particle moving along the x-axis at speed v. Case I: consider the rest frame S' traveling along with x at speed v...

thanks a lot for the replies! I guess i will start with python and see where I end up :) bigerst

I will be going into university this summer, and I intend to learn to code during the summer as it is important to physicist. I have virtually no programming experience. Which language is at the right level and can run complex physical simulations? thanks

I'm reading this book now, it is one of the few physics books I have read (though indeed my experience is limited) that are rigorous and abstract.

Ok that makes much more sense, so it's an effect purely based on time dilation ergo the gamma factors. Thanks.

I don't think you really need differential equations for this one, since there is no external force there is a point on the spring that neither stretches nor compresses. on either side of this point is 2 springs with different spring constants, so effectively you have two different oscillators...

Homework Statement taken directly from Rindler A large disc rotates at uniform angular velocity ω in inertial frame S. Two observers O1 and O2 ride on the disc at radial distances r1 and r2. They carry clocks C1 and C2 they adjust to keep with clocks time with S, i.e., they have been adjusted...

thanks for the reply so the idea is that force is as much a description to the motion as displacement itself (am i understanding this correctly?) then the above formulation completely overthrows the typical problem solving strategy i have encountered: identify the forces that cause the motion...

im just confused, intuitively i'd think a force would cause motion, but at t=0 there is no force, but at the next instant the object starts moving, so what causes it to move? i think there might be something wrong with saying "next instant" since time is continuous? is that the key? Thanks

thanks for the reply that's pretty much what I am facing right now, i wouldn't say i mastered all of the content for i am well aware it is going to take a year or so for those material to sink in and become part of my arsenal, for i can see a gap between myself and really recreating and...

ok i get how forces are interactions but just one more question, does a force cause motion? the example i stumbled upon was the function x=e^-1/t^2 (from mary boas) where the derivative of all orders vanish at t=0, hence is it correct to say that interactions produce Newton's second law, the...

I'm just uncertain (haha), what IS Newton's Second law exactly? F=ma, or F=dp/dt, aren't these defining equations for F itself? what is a force? what would you mean a "force" acts on a object, would it be equally probable to define say, d^3Q/dt^3 = m dx^3/dt^3? does Newton's second law have...

Hello I am a grade 12 student looking to be a physicist. the school course is hardly satisfactory so I did a hell of a lot of self study, I'm wondering in which direction i should head next. I did high school physics in grade 9, calculus in grade 10, first yr uni physics g11, and intro to real...
