On the Emergence of Time in Quantum Gravity
quantum gravity emergence quantum geometrodynamics
2008/4/22
We discuss from a philosophical perspective the way in
which the normal concept of time might be said to `emerge'
in a quantum theory of gravity. After an introduction, we
briefly discuss the notio...
On the problem of emergence of classical space-time: The quantum-mechanical approach
Emergence generalized functions Hilbert space
2008/4/22
The classical space-time structure is derived from the structure of an abstract infinite dimensional separable Hilbert space S. For this S is first realized as a Hilbert space H* of functions of abstr...
Two articles on the reduction of chemistry are examined. The first, by McLaughlin, claims that chemistry is reduced to physics and that there is no evidence for emergence or for downward causation bet...
Integrating research and development: the emergence of rational drug design in the pharmaceutical industry
drug development basic science and technological development
2008/4/14
Rational drug design is a method for developing new pharmaceuticals that typically involves the elucidation of fundamental physiological mechanisms. It thus combines the quest for a scientific underst...
Emulation, Reduction, and Emergence in Dynamical Systems
Reduction emergence models structure of theories
2008/4/11
The received view about emergence and reduction is that they are incompatible categories. I argue in this paper that, contrary to the received view, emergence and reduction can hold together. To suppo...
Recent work on emergence in physics has focused on the presence of singular limit relations between basal and upper-level theories as a criterion for emergence. However, over-emphasis on the role of s...
Emergence in exact natural science
Intertheoretical relations Higher-level theories Singular asymptotic expansions
2008/4/11
The context of an operational description is given by the distinction between what we consider as relevant and what as irrelevant for a particular experiment or observation. A rigorous description of ...
Dynamical Emergence of Instantaneous 3-Spaces in a Class of Models of General Relativity
Achronal 3-spaces in GR Distant simultaneity Endurantism
2008/4/11
The Hamiltonian structure of General Relativity (GR), for
both metric and tetrad gravity in a definite continuous family of space-times, is fully exploited in order to show that: i) the "Hole Argumen...
Contextual Emergence in the Description of Properties
contextual emergence contextual observables molecular shape
2008/4/10
The role of contingent contexts in formulating relations between properties of systems at different descriptive levels is addressed. Based on the distinction between necessary and sufficient condition...
