The idea of designing from patterns to details, in which the design helps promote sustainability, can be compared to a spider building its web where the web shows a spiral pattern but has varying details. This concept can be applied to engineering in various ways. We can observe patterns such as energy consumption or user behavior to design more efficient and better systems, such as building energy-efficient circuits. I found the herb spiral to be quite ingenious and…
