Towards a Group-Theoretical Interpretation of Mechanics
quantum mechanics gauge theories moment map symplectic reduction
2016/6/12
We argue that the classical description of a symplectic manifold endowed with a Hamiltonian action of an abelian Lie group G and the corresponding quantum theory can be understood as different aspects...
Discussions of the concept of disease have largely focused on whether a specific account successfully identifies necessary and sufficient conditions for a state to count as pathological. Correctly acc...

Theoretical technologies in an “experimental” setting: empirical modeling of proteinic objects and simulation of their dynamics within scientific collaborations around a supercomputer
biophysics protein chemistry models simulation experimental data
2009/9/8
This paper examines, as a case study, some modeling and simulating practices in protein chemistry. In this field, theorists try to grasp proteinic objects by constructing models of their structures an...
Species are not theoretical objects, or, On what there is in biology
theoretical objects biology
2009/9/8
It is often claimed that species are the units of evolution, but this is not defined or clearly explained. In this paper I will argue that species are phenomenal objects that stand in need of explanat...
Carnap on Theoretical Terms: Structuralism without Metaphysics
Carnap structuralism structural realism theoretical terms Ramsey sentence
2009/6/5
Both realists and instrumentalists have found it difficult to understand (much less accept) Carnap’s developed view on theoretical terms, which attempts to stake out a neutral position between realism...

Local, General and Universal Prediction Strategies: A Game-Theoretical Approach to the Problem of Induction
Problem of Induction Meta-Induction Prediction Method
2008/4/22
In this paper I present a game-theoretical approach to the problem of induction. I investigate the comparative success of prediction methods by mathematical analysis and computer programming. Hume's p...
Theoretical Omniscience: Old Evidence or New Theory
Bayesian Confirmation Theory Theoretical Omniscience
2008/4/21
I will show that, in the Problem of Old Evidence, unless a rational agent has a property I will call theoretical omniscience (a stronger version of logical omniscience), a problem with non-commutativi...
Emil Rupp, Albert Einstein and the canal ray experiments on wave-particle duality: Scientific fraud and theoretical bias
Emil Rupp Albert Einstein wave-particle duality
2008/4/11
In 1926 Emil Rupp published a number of papers on the interference properties of light emitted by canal ray sources. These articles, particularly one paper that came into being in close collaboration ...
Beyond Theoretical Reduction and Layer-Cake Antireduction: How DNA Retooled Genetics and Transformed Biological Practice
reduction reductionism theoretical reduction
2008/4/10
Watson and Crick’s discovery of the structure of DNA led to developments that transformed many biological sciences. But what were the relevant developments and how did they transform biology? Much of ...
Supporting a Discourse About Incommensurable Theoretical Perspectives in Mathematics Education
Incommensurable Theoretical Perspectives Mathematics Education
2008/4/7
The issue in which I focus in this article is that of coping with multiple and frequently conflicting theoretical perspectives. This issue relates directly to the question of how is mathematic learne...
Towards ‘chemical congruence’ of the models in theoretical chemistry
models in theoretical chemistry theoretical analysis methodological criteria for models
2008/4/7
A series of ‘growth crises’ in the methodological framework of chemistry has led to serious discrepancies between the operational approach used in experimental practice and the methods and models use...
The Epistemological Status of Theoretical Models of Molecular Structure
rigid and dynamic model of molecular structure representation quantum theory of molecular structure
2008/4/7
For many decades, chemists regarded rigid models of molecular structure as representing structures of real molecules as their attributes. However, new experimental data required a new theoretical conc...

George S. Levit Biogeochemistry
2008/4/3
It would be wrong to claim that the life and work of Vladimir Vernadsky (1863-1945) has not been well investigated. Indeed, the attractiveness of Vernadsky’s person and the global character of his the...
