From learning about plywood to translation: “NOT SAFE IF ANY BEAM FAILS.” Pretty, though.

270 pages written by someone with a very dry, academic sense of humour. And ideas and details to inspire.
I like the Schwedler dome page 184
.
“A feature of this dome is that it can be analysed as a statically determinate structure.”
– which led me to find out what a statically determinate structure is, which led me to http://www.ae.msstate.edu/vlsm/truss/statically_det_indet_trusses/statically_det_indet_trusses.htm
“A truss is considered statically determinate if all of its support reactions and member forces can be calculated using only the equations of static equilibrium. For a planar truss to be statically determinate, the number of members plus the number of support reactions must not exceed the number of joints times 2.”
and
Key Observation
Since a statically determinate truss cannot have more members than the number required for stability, it is not a fail-safe structure. This means that if one member of the truss were to fail, then the truss will collapse. This is a major reason for introducing redundant members in truss structures, especially when public safety is of primary concern.”
Translation:  “NOT SAFE IF ANY BEAM FAILS.”
