Andre Julg

From Atoms and Molecules to the Cosmos

A Quasi-Ergodic Interpretation of Quantum Mechanics

• Broschiertes Buch

Produktbeschreibung

André Julg has published several papers concerning the continuity of classical physics and quantum mechanics. He provides a provocative conclusion in this book: the quantum formalism can be effectively interpreted within the framework of classical physics, provided some minor rearrangements are accepted.
