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

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

Maxwell's demon challenges the second law of thermodynamics by potentially decreasing entropy using information

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 Boltzmann's entropy formula states — S = k ln Ω, connecting microscopic states to macroscopic entropy

Boltzmann's formula relates entropy (S) to the natural logarithm of the number of microstates (Ω), with k as Boltzmann's constant

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 quantum Hall effect reveals — Hall conductance is quantized in units of e²/h

Quantum Hall effect shows quantized Hall conductance as e²/h

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
