Emergent Universe

Egon Bondy's Happy Hearts Club Banned is an album by Czech underground band The Plastic People of the Universe. It was recorded in 1974/75, mainly at Houska Castle, enabled by the castle's then warden Svatopluk Karásek, with some songs being recorded in Prague. The album could not be officially released and distributed under the former Communist regime in Czechoslovakia; instead fans duplicated tapes with one another, often resulting in poor technical quality. It was released in 1978 in France by SCOPA Invisible Production. In the Czech Republic a remastered version was published on CD in 2001 by Globus Music. The album title is a parody of The Beatles' album Sgt. Pepper's Lonely Hearts Club Band. Most of the songs on the record are settings of poems by Egon Bondy.

Emergent quantum mechanics explores the possibility of an ontology for quantum mechanics. The resurgence of interest in "deeper-level" theories for quantum phenomena challenges the standard, textbook interpretation. The book presents expert views that critically evaluate the significance–for 21st century physics–of ontological quantum mechanics, an approach that David Bohm helped pioneer. The possibility of a deterministic quantum theory was first introduced with the original de Broglie-Bohm theory, which has also been developed as Bohmian mechanics. The wide range of perspectives that were contributed to this book on the occasion of David Bohm's centennial celebration provide ample evidence for the physical consistency of ontological quantum mechanics.
