Loved this piece. SS is a textbook, a text and reference manual. Rip had me at the moment diagrams, I hadn't seen moment diagrams computed since my undergrad days. To see it applied to strength, to bar path, the analysis of center of mass literally fired me up. And I enjoyed the challenge of learning the anatomy.
And what Bill references in the article about Selye's Law as described in Practical Programming 3rd Ed is required reading. I dont listen to anyone who cannot dwscribe the stress-recovery-adaptation cycle in depth.
I just read a good book that discusses the futility of superficial inderstanding, and the need to "go deep" to develop a knowledge base that has any value . It is called Deep Work by Cal Newpirt. It is a good read and applies to the need to truly go deep to learn and apply complex topics....such as SS.
