hi guys.
i have the london penetration depth defined as \lambda_l = \sqrt{\frac{m^{**}}{4\pi n_{s} e^{2}}}.
i'm trying to figure out the dimensionality of it...surely it must be a length, but i get
[(Kg)(m^{3})(A^{-1}s^{-1})]^{0.5}
in SI units.
am i doing something wrong?
cheers.
i have an equation for the density of states that depends on 1/(sqrt E). i have lots of coefficients to this
[Vm^{3/2} w_c ] / [2 sqrt {2} pi^2 hbar^2]
do these coefficients represent the degeneracy of the desity of states?
i'm revising for an exam and have this question posed (this isn't homework)
what is the maximal velocity for a clock being transported from london to new york if the time difference to a stationary clock should be less than 10^-8 seconds.
i'm not allowed to use calculators.
i've tried...
i have read about the experiment of people ageing slower when moving at velocity and don't quite understand.
here's my experiment:
two people, person A and B, start off in the same referance frame (both are, say 20yrs old). person A flies off in one direction and person B in another. they...
exactly, and from your perspective, your only moving at walking speed, the ship isn't even moving (well, you can't determine if it's moving without an outside referance frame, so you are completely valid in saying the ships not moving).
a bit off topic but i was just thinking. black holes have a large gravitational potential well (is it infinite?)and so anything close to them appears to slow down up to the point that objects never cross the event horizion. to me that signals that time has stopped inside the black hole. if this...
basically, everything would apear normal from your point of view (referance frame). you could walk around just like you can on earth. in fact the only way you can deduce you are moving at 99.99999% speed of light is to compare it to another referance frame but even then you don't know if your...
i was wondering what everyone thought they would see if they fell into a black hole. i know from relativity that from the perspective of me or you on earth, it would take an infinite amount of time for that person to fall in since as they approach the even horizon time dilation becomes very...
