    Shining light on a retreating object

    Homework Statement I came up with this thought experiment last night, but I'm not confident in my solution--mostly because I forgo the time values I thought would be necessary to complete it. A reflective object moves past a lamp at time T0 with constant (non-relativistic) velocity V...

    I Accelerate Charged Particle: Does Light Require Force?

    Sorry, I'm not familiar with the term, "inertial particle". So, it's not relative motion that drives emission, but changes in a charged particle's momentum? For instance, if you shake one particle in a two particle system, the shaken particle will not experience an emission from the...

    I Accelerate Charged Particle: Does Light Require Force?

    Does a charged particle need to experience a momentum changing force to emit light? Or is it sufficient for an observer to accelerate relative to the particle?

    Gravity only illusion due to expansion of universe?

    I wasn't even touching on gravitational waves. Sorry for the confusion. I was hoping the "EM" would be implied on the second set of waves.

    Gravity only illusion due to expansion of universe?

    Hmmm. Interesting, in an electric field, the smaller mass will have a greater acceleration, and emit EM waves of a higher frequency. In a gravitational field, they have the same acceleration and will emit the same frequency. I think a good argument for them being incomparable is that...

    Searching for beginners' Math for Quantum Physics ( maybe too beginners)

    Stunning. You're being awfully condescending for someone who isn't precise enough to distinguish between conducting analysis and gaining an "understanding". Particularly when any "understanding" you could gain would be highly speculative. Almost every QM book I have used has prefaced itself...

    Rigorous proof of basic absolute value theorem?

    I would do something like this. You could be a little more rigorous though. 1. A and B are real numbers. 2. A real number is less than or equal to its magnitude. (by def of absolute value) 3. A + B is a real number (by closure) 4. Assume without loss of generality that A >= B There are...

    Can magnetic field expand faster than light?

    Moonknight, What is it you read?

    Can magnetic field expand faster than light?

    I am going to restate my understanding of your question: If the magnetic field pushes on the charge moving through it, then the charge must push back on something because "every action has an equal and opposite reaction". How is the "push back" manifested? I am not confident in my...

    Searching for beginners' Math for Quantum Physics ( maybe too beginners)

    Once you have derivatives and integrals under your belt, you should be prepared to begin looking at QM. I stress 'looking' because you likely will have trouble with the Diff Eq. parts, but it would be good for you to start understanding that QM is a statistical approach and to grow comfortable...

    Golfer Needs Competing Laws of Physics Explaining Please

    hmmm it DOES operate the same way. You're thinking kind of like a calculator. Where you can only change one side of the equation. Try this:8 = 4 * 2 Now, if you increase 4 to 6 you can either change 8 to 12 to maintain the integrity of the equation OR you can change the 2 to 8/6ths. that...

    Golfer Needs Competing Laws of Physics Explaining Please

    Okay. "If I increase M (whatever such is) then I thereby increase F, and thereby increase distance." There are actually three possible results of increasing M. 1. You increase M, you maintain the acceleration A, so the Force F will increase. 2. You Increase M, but you are...

    Karkas, your enthusiasm for the topic is admirable. I was griping more than commenting on you as a person. To tailor a response to you, what math are you already familiar and comfortable with?

    Searching for beginners' Math for Quantum Physics ( maybe too beginners)

    Fair enough. I have had several math teachers try to use physics as a source of example problem only to see them make a critical conceptual mistake and not be able to identify it because their math was correct.
