Black Holes with Less Entropy Than A/4
Don N. Page
One can increase one-quarter the area of a black hole, A/4, to exceed the total thermodynamic entropy, S, by surrounding the hole with a perfectly reflecting shell and adiabaticall…
Mindless Sensationalism: A Quantum Framework for Consciousness
Don N. Page
The ideas of Sensible Quantum Mechanics are expressed in lay terms for philosophers of consciousness and others. A framework is proposed and explained for the `psycho-physical-para…
Classical and Quantum Action-Phase Variables for Time-Dependent Oscillators
Sang Pyo Kim, Don N. Page
For a time-dependent classical quadratic oscillator we introduce pairs of real and complex invariants that are linear in position and momentum. Each pair of invariants realize expl…
Black Hole Configurations with Total Entropy Less than A/4
Don N. Page
If one surrounds a black hole with a perfectly reflecting shell and adiabatically squeezes the shell inward, one can increase the black hole area A to exceed four times the total e…
