Formal Systems as Physical Objects: A Physicalist Account of Mathematical Truth
mathematical truth physicalism formal systems deduction
2008/4/22
This paper is a brief formulation of a radical thesis. We start with the formalist doctrine that mathematical objects have no meanings; we have marks and rules governing how these marks can be combine...
On the Physical Consistency of the Special Theory of Relativity (STR)
Special Theory of Relativity Lorentz Transformations
2008/4/22
There are well-established facts whose validity is beyond any doubt, such as the fact that 2 + 2 = 4 or the fact that, say, a lamp that can only flash once in its entire lifetime can only flash at a g...
Physical Models and Fundamental Laws: Using One Piece of the World to Tell About Another (Pavia MBR'01 version)
Models similarity laws analogical reasoning
2008/4/22
In this paper I discuss the relationship between model, theories, and laws in the practice of experimental scale modeling. The methodology of experimental scale modeling, also known as physical simila...
Physical Relations or Functional Relations ?A non-metaphysical construal of Rovelli’s Relational Quantum Mechanics
Quantum mechanics relational interpretation
2008/4/22
Rovelli’s RQM is first characterized by contrast with both Everett’s and Bohr’s interpretations of quantum mechanics. Then, it is shown that a basic difficulty arises from the choice of formulating RQ...
The purpose of this paper is to discuss the various types of physical universe which could exist according to modern mathematical physics. The paper begins with an introduction that approaches the que...
PROBABILISTIC EVENTS AND PHYSICAL REALITY: A COMPLETE ALGEBRA OF PROBABILITY
Probability foundations random events
2008/4/22
This contribution derives from a rather extensive study on the foundations of probability. We start by discussing critically the two main models of the random event in Probability Theory and cast ligh...
The definability of physical concepts
theory of definition definability of physical concepts
2008/4/21
Our main purpose here is to make some considerations about the definability of physical concepts like mass, force, time, space, spacetime, and so on. Our starting motivation is a collection of suppose...
The Fundamental Principles of Existence and the Origin of Physical Laws
ontological principles of reality reduction of biology to physics
2008/4/21
In this essay the ontological structure of reality is explored. The question of reducibility of biology to physics is considered in the context of their ultimate principles. It is shown that biology i...
Standard Quantum mechanics (SQM) deals with observers, frames of reference (apparatus) and systems under observation (SUOs). Heisenberg based his approach to quantum mechanics on a desire to avoid met...
The Many-Worlds Interpretation of Quantum Mechanics: Psychological versus Physical Bases for the Multiplicity of "Worlds"
Psychological Quantum Mechanics
2008/4/21
This unpublished 1990 preprint argues that a crucial distinction in discussions of the many-worlds interpretation of quantum mechanics (MWI) is that between versions of the interpretation positing a p...
The representation of facts in physical theories
Breaking of the time-reversal symmetry Nonanticipative behavior
2008/4/21
The purpose of this contribution is to call attention to a problem which has not received the interest which, in my opinion, it deserves: the problem of representation of facts in physical theories. T...
On the nature of continuous physical quantities in classical and quantum mechanics
quantum mechanics physical quantities
2008/4/15
Within the traditional Hilbert space formalism of quantum mechanics, it is not possible to describe a particle as possessing, simultaneously, a sharp position value and a sharp momentum value. Is it p...
Holism, Physical Theories and Quantum Mechanics
Quantum Mechanics Physical Theories Holism
2008/4/14
Motivated by the question what it is that makes quantum mechanics a holistic theory (if so), I try to define for general physical theories what we mean by `holism'. For this purpose I propose an epist...
Explaining Leibniz equivalence as difference of non-inertial appearances: dis-solution of the Hole Argument and physical individuation of point-events
Hole Argument
2008/4/11
”The last remnant of physical objectivity of space-time” is disclosed in the case of a continuous family of spatially non-compact models of general relativity (GR). The physical individuation of point...
EPR Paradox and the Physical Meaning of an Experiment in Quantum Mechanics
the Physical Meaning of an Experiment EPR Paradox
2008/4/11
It is shown that there is one purely deterministic outcome when
measurement is made on the state function chosen by EPR to describe the
combined two-particle system – the distance between the two pa...
