Physics and probability: essays in honor of E.T.Jaynes

The pioneering paintings of Edwin T. Jaynes within the box of statistical physics, quantum optics, and likelihood concept has had an important and lasting influence at the learn of many actual difficulties, starting from primary theoretical questions via to sensible purposes akin to optical picture recovery.
