    How can I master physics?

    Wow, Thank you Hiero But, can you suggest me any good source? I mean is the source a book or do I have to create the source myself?

    How can I master physics?

    Greg, I'm ready to work and practice a lot, as I have said in my question. But the problem is, I don't know how do I go about this. I don't want to put my work blindly everywhere. I just wanted some path where can I go, so that I get a good deal of knowledge about this subject. I thought that it...

    How can I master physics?

    Hello everyone, and first of all I would like to clarify that I don't think I'm asking a regular "how do people do physics" out of frustration. I am really interested in physics and I've joined a university for my Under Grad Physics course, and I want to go beyond what my course teaches. Is...

    B Is a "meter" observer dependent?

    Thank you...Helped me a lot

    B Is a "meter" observer dependent?

    I would like to know whether this occurs along with Lorentz contraction due to OUR definition of a meter.

    B Is a "meter" observer dependent?

    I tried to mean like this....Think of a giant wall(stationary wrt earth) beside both of them, and think that they have the ability to mark exactly as per the SI definition on that wall...Now, when a beam of light passes they do their measurement. Now, as time dilates for the person in motion...

    B Is a "meter" observer dependent?

    SI defines one meter as the distance travelled by light in one upon 299792458(=k) seconds, from which we get that, D=c*k, where k is marked above. So, let's consider two frames on at rest wrt the earth(f1) and another moving at, say 0.99*c(f2). SR says that the time dilates for f2 wrt f1. And...

    Magnetic field due to a current carrying loop

    Wow! Thanks, but what does that 'high symmetry' here signify?

    Magnetic field due to a current carrying loop

    Homework Statement The actual question was to somehow derive the expression for a magnetic field at the center of a current carrying loop. Homework Equations The Biot-Savart's law equation dB = (mu/4π)*(i dl x r)/r^3 (I'm not actually good at typing in the equations, so please just forgive...

    Phase and Phase difference.....Can somebody enlighten me?

    Or can I say like this...phase is the condition/position of a particle at a particular point and at a particular instant of time in a travelling wave, and difference between trigonometric arguments of a particular particle at different instants of time is phase difference. Is that right...

    Phase and Phase difference.....Can somebody enlighten me?

    I'm currently studying wave mechanics(high school level), and more thing that makes scribble all over is the concept of phase and Phase difference. After these long tries, I could mathematically think of what they are, but cannot geometrically or logically express it. Can someone help me out.....

    Acceleration of wedge due to normal force exerted by block?

    Yup, Exactly what I had in my mind...

    Is Matter Created continuously?

    This was not actually my intention. I'm just now starting to learn this amazing science of quantum mechanics, and this one popped into my mind(a misconception, of course), so I just wanted to clarify this.

    Acceleration of wedge due to normal force exerted by block?

    Actually, what I thought was normal force was caused due to gravity(when no other force acts on the system),So, if we consider this set-up in space, will there be a normal force? Also in this space set-up the gravitational attraction between the two particles will be negligible...

    Acceleration of wedge due to normal force exerted by block?

    Yes, Of course I could understand your reply, and I don't argue that why should the block move along the incline, all I doubt is, will the wedge move in the opposite direction, due to the motion of the ball(if gravity is the only force acting on the system)?

    Is Matter Created continuously?

    But, casimir effect, which is based on the interaction of VPs, has been already proved and hence, existence of VPs are also proved! And today, many scientific theories(including the famous Hawking Radiation), are based on this interaction. Therefore, if VPs don't exist, then many theories are...

    Acceleration of wedge due to normal force exerted by block?

    This isn't actually a problem. It is a doubt which I have about wedges according to Newton's Laws Consider a friction less wedge, of mass 'M', inclined at angle θ, placed on a smooth horizontal surface, on which a block of mass 'm' is placed. The block exerts some normal force perpendicular to...

    Is Matter Created continuously?

    I've studied in many books, from which I learnt that a vacuum is not truly a vacuum, that is, virtual particles are created every time. And I had also learnt that the universe is left handed, that is a small non obeying in parity symmetry(individually), resulted in production of around one in a...

    'And' means 'Multiply' and 'Or' means 'Add'?

    Yes! I do know that this involves only combinatorics...But I wondered, whether this principle is followed in combinatorics too?

    'And' means 'Multiply' and 'Or' means 'Add'?

    Mentor note: Moved from a non-HW forum section, so missing the HW template When I was attending probability class, my math teacher said me that in the problems involving Case 1 'and' Case 2, I have to multiply probability of Case 1 and Case 2, while in the case of Case 1 'or' Case 2, I have to...

    How did Maxwell's theory predict that c is constant?

    Ha, well said! Thank you.

    How did Maxwell's theory predict that c is constant?

    Yes, SR does say that. But Maxwell's time was when people believed in "absolute time", that is there were no ideas of time dilation. For "them", it was "possible" to catch up with the speed of anything!
