Entropy Quote by Basil Mahon

“Leo Szilard, in 1929, showed that the very act of acquiring information about a system increases its entropy in proportion to the amount of information gathered. As the entropy increases, less of the system's total heat energy is available for doing work. To gather enough information to work the…” quote by Basil Mahon

““Leo Szilard, in 1929, showed that the very act of acquiring information about a system increases its entropy in proportion to the amount of information gathered. As the entropy increases, less of the system's total heat energy is available for doing work. To gather enough information to work the shutter effectively we would have to use up, or render inaccessible, an amount of energy at least equal to the work output of any machine that we could drive from the system. So we will never be clever enough to create perpetual motion. Through the work of Szilard and others, Maxwell's demon helped to spark the creation of information theory, now an essential part of the theoretical basis of communications and computing.””

About This Quote

Acquiring information about a system inevitably raises its entropy, limiting the usable energy and preventing perpetual motion.

In simple terms: Gathering info costs energy, so you can’t get free work.

Key Takeaway

Information has a thermodynamic cost.

Themes

physics information theory thermodynamics limits perpetual motion

Mood

thoughtful analytical
