    <div class="sphx-glr-thumbcontainer" tooltip="Ordinary critical phenomena (the Ising transition, percolation) require tuning a parameter -- temperature, occupation probability -- to a precise critical value. Bak, Tang, and Wiesenfeld&#x27;s 1987 sandpile model showed that some driven, dissipative systems tune themselves to criticality through their own dynamics, with no external parameter to adjust.">
