+          This simulator models both the forgetting curve and how memories become more stable with repeated retrievals:

+          The simulator models three key memory phenomena:
+        </p>
+        <ol class="mt-2 list-decimal pl-5 space-y-1">
+          <li>
+            <strong>Exponential decay</strong>: Memories naturally fade over time following Ebbinghaus' forgetting curve
+          </li>
+          <li>
+            <strong>Retrieval practice effect</strong>: Each retrieval boosts the memory strength temporarily
+          </li>
+          <li>
+            <strong>Long-term memory formation</strong>: After sufficient retrievals, memories become increasingly stable
+            and resistant to decay, eventually becoming "permanent"
+          </li>
+        </ol>
+        <p class="mt-3">
+          This reflects how the brain forms long-term memories through a process of neural consolidation,
+          where repeated activation of neural pathways leads to structural changes that stabilize memories.
+          The spaced repetition study method leverages this effect for efficient learning.
