What Maxwell's demon thought experiment challenges — can information be used to decrease entropy

What the second law of thermodynamics says — entropy of an isolated system never decreases

Entropy in an isolated system always increases or remains constant

What the information paradox asks — does information falling into a black hole disappear, violating quantum mechanics

The information paradox questions: Does information vanish in black holes, contradicting quantum theory?

What the arrow of time problem asks — why does time have a direction when fundamental laws are time-reversible

The arrow of time problem questions why entropy increases in one direction despite time-reversible laws

What Landauer's principle resolves — erasing one bit of information dissipates at least kT ln 2 of energy

Landauer's principle states energy dissipation during bit erasure is kT ln(2)

How does the concept of information entropy, as described by Claude Shannon, contribute to understanding the complexity and unpredictability of communication systems?

Information entropy quantifies uncertainty and complexity in communication systems, aiding in efficient data encoding and transmission

What Einstein's 1905 Brownian motion paper proved — the existence of atoms by explaining pollen's random motion

Brownian motion confirmed atoms' existence through pollen's erratic movement
