Hello,
I was solving the time dependent schrodinger equation in a time-independent potential such that E<V and I got the following solution:
ψ = exp(-\sqrt{k}x - (iE/\bar{h})t)
where k > 0 and k = (2m/\bar{h}^{2})(V-E)
I was wondering if this was a left traveling wave i.e. whether I...
Hello,
So I am confused on whether the statement that "a function f exists at all points in an open subset U of (say) R" , indicates that it is well-defined on all the points in that subset i.e will the function have a real value on all the points in the subset?
Also, can the derivative of...
Thanks twofish-quant. I appreciate your advice. Its not that I don't enjoy my courses, nor is it that they're easy courses. I was taking two fourth year courses and three third year courses this semester even though I am in my third year, as these courses are more relevant to my program than...
Hi,
Thanks very much for the advice guys. YesI am in my third year of mathematical physics. I was in engineering physics and thus had a lot of courses in common with the physics program. I then took the required math courses over the summer. The thing is, I've been spending all my time on...
I also wanted to ask, if I do well in my masters, will I be in a better position to get into academia, regardless of my undergrad gpa? Does it all depend on the research you conduct during your masters, or the grades?
Hello,
I am currently in my third year of Mathematical Physics. I was in biology in my first year and in Engineering physics in my second year. I knew my interest was in physics but tried the former just to please my parents. Upon getting into a depression in my second year due to lack of...
I never thought of it that way. I guess from the cm frame, it itself is stationary and the points around it rotate about it. It makes sense now. Thanks very much! =]
I don't quite understand =[
The points around the centre of mass always maintain the same constant position around it, i.e. the body doesn't rotate ABOUT the centre of mass. As the position of the centre of masss changes relative to the origin, so do the positions of the other points. I seem...
Wouldnt the centre of mass and all the other points around it have the same angular speed with respect to the origin though? If that would be the case then the angular speed of those points with respect to the centre of mass would be zero right?
help with parallel axis theorem??
Hey guys,
I've attached a picture from my textbook (Intro to Classical Mechanics by David Morin) showing the beginning of the proof for the parallel axis theorem. I understand most of it except the sentence where it states that if you glue a stick to the body...
AHH! That helps a lot and the relativistic mass concept is interesting! xD
I really need to word myself more carefully.
I thought the concept of time dilation arose because the speed of light is the same in all reference coords. What I meant by the quoted statement is that in the situation...
ah sorry for taking so long to reply, I was thinking about the stuff. Thanks very much for helping me!
I am actually confused with the cause of time dilation. The only "reason" I know is the derivation of the formula; however, my brain thinks that the derivation is based on two observers...
Ah, bad way of wording it, I meant one observer moving at a speed close to c wrt to the other xD And I am confused because I don't understand how time dilation applies to such a situation. I found derivations of time dilation with the mirror-light source situation, but couldn't find any where...
