It has been known since the 1930s that quantum mechanics can be formulated in quaternionic as well as complex Hilbert space. But systematic work on the quaternionic extension of standard quantum mecha

Quantum mechanics is our most successful physical theory. However, it raises conceptual issues that have perplexed physicists and philosophers of science for decades. This 2004 book develops an approach, based on the proposal that quantum theory is not a complete, final theory, but is in fact an emergent phenomenon arising from a deeper level of dynamics. The dynamics at this deeper level are taken to be an extension of classical dynamics to non-commuting matrix variables, with cyclic permutation inside a trace used as the basic calculational tool. With plausible assumptions, quantum theory is shown to emerge as the statistical thermodynamics of this underlying theory, with the canonical commutationticommutation relations derived from a generalized equipartition theorem. Brownian motion corrections to this thermodynamics are argued to lead to state vector reduction and to the probabilistic interpretation of quantum theory, making contact with phenomenological proposals for stochasti

"Immediate and evocative, letters witness and fasten history, catching events as they happen," write Lisa Grunwald and Stephen J. Adler in their introduction to this remarkable book.??In more than 400

Historical events of the last three centuries come alive through these women’s singular correspondences—often their only form of public expression. In 1775, Rachel Revere tries to send financial aid t

The revised, updated Fifth Edition of this pocket book is a handy reference to consult when making bedside interpretations of clinical data. Remarkably complete for its small size, the book lists nea

Bipolar disorders affect up to 3% of the world's population and are the 6th leading cause of disability worldwide. The estimated annual costs of bipolar disorder approach $50 billion in the United Sta

Wild Spaces, Open Seasons traces the theme of hunting and fishing in American art from the early nineteenth century through World War II. Describing a remarkable group of American paintings and sculpt

What does it mean to say that a painting has been “invaded” by language? Art, Word and Image answers this question by exploring how visual images and writing can work in dialogue in an ar
