Carter Submission history [v1] 2012-10-22 16:16:26 [v2] 2013-05-24 23:05:39 [v3] 2014-01-24 13:08:40 The ubiquity of complex numbers throughout fundamental physics has never been satisfactorily explained. Moreover, the mathematical primacy of complex and imaginary numbers suggests the primacy of complex and imaginary structures in Nature, while further implying the existence of imaginary spatial dimensions preceding real dimensions. On this basis a consistent cosmological Read more […]

Ghost in the atom

Ghost in the atom Marcus Chown New Scientist, 28 July 2012 In quantum theory the wave function encodes all the possible behaviours of a quantum system and allows the calculation of the probability of finding a particle at any particular point in space. The tradition in quantum physics has been to regard the wave function as a convenient abstraction for the purpose of calculations, and as being just a probability distribution. The alternive is that the quantum wave is a real underlying Read more […]

Interpretations of quantum theory

Physics: Interpretations of quantum theory Elegance and Enigma: Quantum Interviews Ed. Maximilian Schlosshauer Springer (2011) Keywords:  collapse theories, pilot-wave theories, decoherence, quantum information This book demonstrates that the different interpretations of quantum theory are becoming more distinct and more entrenched, rather than showing any sign of moving towards any kind of consensus. In particular, six types of approach are distinguished, (1.) Everett many-world Read more […]

Freewill and the block universe

Posted by

A Century of Time J.R. Lucas In:- The Arguments of Time – Ed. Jeremy Butterfield – British Academy/Oxford University Press INTRODUCTION:  The openness or otherwise of the future is important in any consideration of free will or the agency role of consciousness. The view that there is no past/future distinction is sometimes referred to as the ‘Block Universe’ in which the universe is a single block of time, just as it is a single block of space. This idea derives from one interpretation Read more […]
