Happy you think so too.
Here's a specific discussion that I found useful:
One quote in particular reminded me of things Erick is writing about
"[T]ension and compression often operate at 90 degrees to each other. Tense a rope and its girth goes into compression. The fibers crowd closer and closer together. Load a pillar, and its girth widens slightly, as the weight it is supporting pushes its molecules apart into tension. If you pull on a rope, its fibers compress together. If you push on a pillar, it gets (maybe only a very little) wider in the middle."
