Astronomers evidence Einstein theories star orbiting massive black hole
2019/10/22
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. Instead, astronomers turn their att...

三亚国际数学论坛 Superconformal Field Theories in 6 Lower Dimensions
2017/11/24
Conformal field theories represent a very active research field worldwide with many international experts working on various aspects of the topic. Progress during the past several years has led to man...

On Identifying Background-Structure in Classical Field Theories
background-structure background-independence geometric objects absolute objects space-time structures Newton Einstein Newtonian mechanics Newtonian gravitation general relativity classical field theories action-reaction principle Trautman-Anderson-Friedman programme
2016/6/15
I examine a property of theories called ‘background-independence’ that Einsteinian gravitation is thought to exemplify. This concept has figured in the work of Rovelli (2001; 2004), Smolin (2006), Giu...
Empirically Adequate but Observably False Theories
empirical adequacy truth coordinated isomorphism strict empirical adequacy
2016/6/14
I show that a theory may be empirically adequate according to van Fraassen's definition even though it can be observationally determined that the theory is false. I suggest a modification of empirical...
The Semantics of Scientific Theories
semantics of theories logical empiricism received view theoretical terms vagueness analyticity analytic-synthetic distinction
2016/6/14
Marian Przełęcki’s semantics for the Received View is a good explication of Carnap’s position on the subject, anticipates many discussions and results from both proponents and opponents of t...
Lateral and vertical transfer in biology,linguistics and anthropology-An account of widely neglected ideas in the formation of evolutionary theories
unilinear transmission of cultural and biological replicators phylogenetic images of descent tree of life and the tree of languages metaphors 'antidotes' to evolution lateral and vertical transfer in biology linguistics and the history of sciences networks and reticulations Sprachbund mixed languages endosymbiosis cultural diffusion anti-evolutionism evolutionary epistemiology
2016/6/14
Models of biological and cultural evolution that developed from the 19th century onward are characterized by two main features:(1)They were mostly centered on the unilinear transmission of cultural an...
Causality and Chance in Relativistic Quantum Field Theories
Local causality Microcausality Bell correlations Relativistic quantum field theories Pragmatist interpretation Causal intervention
2016/6/13
Bell appealed to the theory of relativity in formulating his principle of local causality. But he maintained that quantum field theories do not conform to that principle, even when their field equatio...
The emergence of spacetime in quantum theories of gravity

This is the introduction to the special issue of Studies in the History and Philosophy of Modern Physics on the emergence of spacetime in quantum theories of spacetime.
Pragmatists and Purists on CPT Invariance in Relativistic Quantum Field Theories
quantum field theory CPT theorem causal perturbation theory
2016/6/12
Philosophers of physics are split on whether foundational issues in relativistic quantum field theory (RQFT) should be framed within pragmatist approaches, which trade mathematical rigor for the abili...
Inertial motion,explanation,and the foundations of classical spacetime theories
Inertial motion geodesic principle general relativity Newton-Cartan theory geometrized Newtonian gravitation explanation puzzle-ball view
2016/5/31
I begin by reviewing some recent work on the status of the geodesic principle in general relativity and the geometrized formulation of Newtonian gravitation. I then turn to the question of whether eit...
