Demon's Cost

Bits measured by the demon

Each decision = at least 1 bit in the demon's notebook. Landauer (1961): erasing one bit dissipates kT·ln(2) ≈ 2.85×10⁻²¹ J at room temp. The notebook IS the entropy sink.

Press play. With Color Demon on, reds slide left, blues slide right. Watch S drop from ~2 bits to ~1 bit as the chambers segregate.
