The Evolution of Useful Things A Book by Henry Petroski Here, then, is the central idea: the form of made things is always subject to change in response to their real or perceived shortcomings, their failures to function properly. This principle governs all invention, innovation, ingenuity.

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
