• Lots on Audio Coding...
  Created 1-29-99

• A Fallacy in the Model + Coder paradigm
  Created 6-28-98

• An Adaptive Quantum Coder
  Created 1-13-98, Modified 1-18-98.

• The 2nd law of thermodynamics implies you cannot compress all possible inputs, and other info-theoretic results. (!) Now with Quantum Info analogue. Created 1-10-98, Modified 1-28-98.

• Is there more than one bit per bit? . Created 12-17-97, Modified 12-30-97.

• How big is nothing? , and notes on the general-purpose channell. Created 12-24-97, Modified 12-30-97.

• physical time-asymetry, and entanglement With a new definition of "complexity". Biological applications. Created 11-17-97. Modified 12-24-97.
