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.

The garden is a riot In conventional agriculture, vegetation is kept at the weed or herb level using energy to keep it cut, weeded, tilled, fetilised, and even burnt; that is, we are constantly setting the system back and incurring work and energy-costs when we stop natural succession from occurring. Instead of fighting this process, we can direct and accelerate it to build our own climax species in a shorter time. There is no attempt to form the garden into strict neat rows; it is a riot of shrubs, vines, garden beds, flowers, herbs, a few small trees, and even a small pond. Paths are sinuous, and garden beds might be round, key-holed, raised, spiraled, or sunken. Bill Mollison, Introduction to Permaculture 172. Garden Growing WildChef's Table: Jeong Kwan gardens
