On the origin of quantum mechanics [PDF]
, 2005 Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the ...

Physical Determination of the Action
arXiv: History and Philosophy of Physics, 2013 The objective is a foundation of physics from the operationalization of its basic observables. We begin with classical and relativistic kinematics. Seizing on a programmatic proposal by Heinrich Hertz we arrive via quantification of energy-momentum at the equations of motion and the action functional.

Group action in topos quantum physics [PDF]
Journal of Mathematical Physics, 2013 Topos theory has been suggested first by Isham and Butterfield, and then by Isham and Döring, as an alternative mathematical structure within which to formulate physical theories. In particular, it has been used to reformulate standard quantum mechanics in such a way that a novel type of logic is used to represent propositions. In this paper, we extend

Interacting Two-Time Physics Field Theory With a BRST Gauge Invariant Action
, 2006 We construct a field theoretic version of 2T-physics including interactions in an action formalism. The approach is a BRST formulation based on the underlying Sp(2,R)gauge symmetry, and shares some similarities with the approach used to construct string ...

A variant approach to the overlap action [PDF]
, 2000 I describe an implementation of the overlap action, which is built from an action which is itself an approximate overlap action. It appears to be about a factor of 15-20 less expensive to use, than the usual overlap action with the Wilson fermion action ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

A non-abelian analogue of DBI from $T \overline{T}$
SciPost Physics, 2020 The Dirac action describes the physics of the Nambu-Goldstone scalars found on branes. The Born-Infeld action defines a non-linear theory of electrodynamics. The combined Dirac-Born-Infeld (DBI) action describes the leading interactions supported on a

Girls in the physics classroom: a review of the research on the participation of girls in physics [PDF]
, 2006 A review of research spanning the past 15 years into the participation of girls in physics at secondary school level. The review was commissioned by the Institute of Physics in order to inform policy setting agendas for the Institute and to reveal ...

Exploring the action landscape with trial world-lines
, 2010 The Hamilton action principle, also known as the principle of least action, and Lagrange equations are an integral part of advanced undergraduate mechanics.

Physicalism and the determination of action [PDF]
, 2011 There is no single version of physicalism. There is no single argument for physicalism. There is, accordingly, no standard answer concerning the implications of physicalism for the causation of human action by mental states. This chapter begins by describing a preferred version of physicalism and its implications about the connection between subjects ...
