comment Numerical Error Propagation
Great answer and I've definitely bookmarked it, but I'm looking for the method of calculus for this particular problem.

comment Numerical Error Propagation
$ \delta g = g_{0}(\frac{\delta L}{L_0}+2\frac{\delta T}{T_0}) $ My issue is what to plug in for the naught values. I've just plugged in averages and what the calculated value of $g_0$ was, and I got a fair value with doing that, but is that the proper method? ( The period has factor $2$ because I used $ g = \frac{4\pi^2 L}{T^2} $

How familiar are you two with differential equations?

Yes. Do fits for velocity-time and position-time, and if you can get analytical functions for x(t) and v(t) that'll make things a lot easier.

Even better! You can do it numerically! ( Numerical methods are so drab :C ) But yes! I've got to run a quick errand, and if no one has showed you how by my return, I'll go ahead and give you a quick run down of the general method.

It's going to get really messy really quick without the coefficient of friction. If you have enough information regarding positions and velocities, you can set up a differential equation and solve for friction on each surface.

comment Understanding the cause of the big bang
Cosmology is the field of study that my undergrad thesis will be in. I've got a multitude of books on the prerequisite math and physics. Currently I'm following Leonard Susskind's Theoretical Minimum which is inclusive of Cosmology!

By most agreed upon, I mean the theories with the most support by whatever means. (I would assume observational evidence.)

comment Understanding the cause of the big bang
I'd never heard the whole point-singularity idea explained in terms of the scale factor. I've always just had sort of an intrinsic understanding of the idea. That's good to know, and makes a ton of sense! ( I've restrained myself from pushing into the mathematics of cosmology until I get to it in Leonard Susskind's Theoretical Minimum )

Fair enough. Editing. But in what way do you find it misleading?
