The Criticality in Sandpiles and BrainsWhy nature prefers to balance on the brink of collapse

Complex systems maximize efficiency by maintaining a state of precarious instability. Using the Bak-Tang-Wiesenfeld model, this story reveals how a single grain can trigger avalanches of unpredictable sizes. This mathematical signature connects earthquake frequencies to neuronal activity, showing that teetering on the edge of disorder is actually essential for adaptability.
