Safety cut rope axe man In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.

Design is a connection between things The core of permaculture is design. Design is a connection between things. It's not water, or a chicken, or the tree. It is how the water, the chicken and the tree are connected. It's the very opposite of what we are taught in school. Education takes everything and pulls it apart and makes no connections at all. Permaculture makes the connection, because as soon as you've got the connection you can feed the chicken from the tree. To enable a design component to function efficiently, we must put it in the right place. Bill Mollison, Introduction to Permaculture To call each thing by its right name design
