Summary

Story summary

Recent research links heat flow to the knowledge of physical systems, tying thermodynamics to information.
Physicist Nicole Yunger Halpern emphasizes the significance of this relationship between information and thermodynamics.
James Clerk Maxwell proposed a demon that could sort gas molecules to create temperature differences.
Scientists show the demon's memory would saturate, requiring erasure that produces more entropy than it saves, linking information to entropy, with experimental validation in 2010.
