Synergetics by Buckminster Fuller

I found a free copy of the book here, of particular interest to us syntegralists. The following sections relate to my writing on leverage and compression here.

792.30: Tension and Compression: Everything we call structure is synergetic and exists only as a consequence of interactions between divergent compressional forces and convergent tension forces.

792:40: Tidal Complementarities: We have demonstrated experimentally that tension and compression always and only coexist. One can be at high tide of visibility and the other coincidentally atlow tide, or vice versa. These tidal covariables are typical complementarities: They are not mirror images of one another, but must always balance one another complexedly in physical equations.
