Thankyou for your reply.
Why do the resulting equations give all geodesics, including null geodesics, as affine-parameterized curves?
because we are optimising s hence finding the shortest path through space-time?
I have an example question (and the corresponding solution) for the metric I...
What are you trying to do when you find parametric equations for a geodesic lines on a surface?
Take the metric ds^2 = dq^2 + (sinh(q)*dp)^2
Are you simply trying to get q as a function of s? and p as a function of s?
If so, why?
Thanks
I have a fission exam next week, can someone help me with this past paper question:
If you know the masses of two nuclei (A)Z and (A+1)Z, (say masses are (A) and (A+1)) and you know the 'critical fission energy' of (A+1)Z, how do you determine if (A)Z is fissile? if it is not fissile, at...
Can someone show me how to integrate any (or both) of these two simple equations. I have written down the equation that needs integrating and the final result and attached them as a pdf.
Regards,

Lenz's Law states that in a given circuit with an induced EMF caused by a change in a magnetic flux, the induced EMF causes a current to flow in the direction that opposes the change in flux. That is, if a decreasing magnetic flux induces an EMF, the resulting current will oppose a further...
Is it possible to put these three equations into a matrix equation
w*a = b -2a + e
w*b = c -2b + a
w*c = d -2c + b
of the style w*u = T*u where u is a vector, u = {a, b, c} and T is a matrix. w is just a number.
I am doing a project on tightly-coupled processive molecular motors. My 1D model consists of motors which literally step discrete step sizes of size U while executing a biased random walk along a filament which moves along its longitudinal axis with negligible drag. The motors are attached to a...
