I’ve been fascinated by the idea of the four fundamental forces in physics ever since I first learned of the idea. I used it as a metaphor for Big History in A Brief History of the Corporation a few years back. Brian Skinner’s meditation on Coulomb interactions and some conversations with my favorite crazy engineer Artem Litvinovich (blog, twitter) have gotten me thinking about the four forces again.
I made up a metaphorical mapping of the four forces to sociology. It’s not pretty, but it’s interesting.
