Time in Quantum Mechanics
Quantum Mechanics
2008/4/21
Time is often said to play in quantum mechanics an essentially different role from position: whereas position is represented by a Hermitian operator, time is represented by a c-number. This discrepanc...
Richard Feynman has claimed that anti-particles are nothing but particles `propagating backwards in time'; that time reversing a particle state always turns it into the corresponding anti-particle sta...
Contrary to the informed consensus, time travel implies spontaneity (as distinct from chance) so that time travel can only be of the second kind.
This paper is a survey of the theories of time travel in a perspective close to theories of time. In the last section we discuss the special ontology of the objects that exist on closed timelike curve...
Relativity, Special and General represent Time as a linear dimension in a 4-diemnsional spacetime. However, one of the important ways in which time can be distinguished from space is through the exami...
In this paper I try to sort out a tangle of issues regarding time, inertia, proper time and the so-called “clock hypothesis” raised by Harvey Brown's discussion of them in his recent book, Physical Re...
This is a copy of my DPhil thesis, the abstract for which is as follows:
The first third of this thesis argues for a B-theoretic conception of time according to which all times exist equally and th...
The Everett interpretation of quantum mechanics has repeatedly been criticized on the grounds that probabilty makes no sense on its terms. These criticisms are considered in detail, and found to be wa...
This contribution explores Wolfgang Pauli's idea that mind and matter are complementary aspects of the same reality. We adopt the working hypothesis that there is an undivided timeless primordial real...
Time-reversal invariance and irreversibility in time-asymmetric quantum mechanics
quantum mechanics irreversibility time-reversal invariance
2008/4/21
The aim of this paper is to analyze the concepts of time-reversal invariance and irreversibility in the so-called 'time-asymmetric quantum mechanics'. We begin with pointing out the difference between...
In the literature on the compatibility between the time of our experience and the time of physics, the special theory of relativity has enjoyed central stage. By bringing into the discussion the gener...
Moderate structural realism about space-time
structural realism structure relations intrinsic properties
2008/4/15
This paper sets out a moderate version of metaphysical structural realism that stands in contrast to both the epistemic structural realism of Worrall and the – radical – ontic structural realism of Fr...
It is argued that Minkowski space-time cannot serve as the deep structure within a ``constructive'' version of the special theory of relativity, contrary to widespread opinion in the philosophical com...
Indeterminism, Asymptotic Reasoning, and Time Irreversibility in Classical Physics.
determinism indeterminism acausality
2008/4/14
A recent proposal of Norton (2003) to show that a simple Newtonian system can exhibit stochastic acausal behavior by giving rise to spontaneous movements of a mass on the dome of a certain shape is ex...
Modern cosmology treats space and time, or rather space-time, as concrete particulars. The General Theory of Relativity combines the distribution of matter and energy with the curvature of space-time....
