The Spacetime Metric

In the (epic?) conclusion to our metric tensor trilogy, we dive a little deeper into the origins of the metric tensor in an attempt to bridge the conceptual gulf that lies between our ordinary, intuitive understanding of geometry and that abstracter comprehension of it required to master General Relativity's four-dimensional spacetime. Can we pave ourselves a path to clearer understanding in twenty minutes? Let us know in the comments.
