Classic gravitational tests of post-Einsteinian theories

|

With the help of PPN formalism, gravity theories are confronted with the results of experiments in the solar system. The γ parameter in this formalism highlights the light deflection and the light delay. By calculations according to PPN, light deflection … Read More

Blockchain and the causal tree of reference

|

In a previous article, Philosophy of Blockchain Technology – Ontologies, (Sfetcu 2019) I talked about applying Paul Ricœur’s narrative theory in developing an ontology of blockchain technology. In this section I intend to highlight the idea of an analogy between … Read More

Testing the relativistic theories of gravity

|

Clifford M. Will describes, in Theory and Experiment in Gravitational Physics, [1] the emergence of a new era for general relativity, testing and checking at very high levels of accuracy. In 1959, scientists at Lincoln Laboratories in Massachusetts bombarded the … Read More

Evaluation of post-Einsteinian gravitational theories through parameterized post-Newtonian formalism

|

Proliferation of post-Einsteinian gravitational theories Right after the elaboration and success of general relativity (GR), alternative theories for gravity began to appear, which can fall into four broad categories: [1] Bifurcated theories (with the Lakatosian[2] hard core identical or very … Read More

Causal Theory of Reference of Michael Devitt

|

Michael Devitt develops a hybrid causal theory of non-empty proper names and certain singular terms that semantically resemble them. He considers that the use of a name designates an object not by virtue of the different information we know about … Read More

Heuristics of the General Relativity

|

The essential principle of coordination in GR is the principle of equivalence, including a negative heuristic. The argument “is not that all reference frames are equivalent, but that the classical coordination of uniform motion in a straight line with the … Read More

Dear Nicolae Sfetcu, Re: Excellence in Quality and Management Forum (Cannes France) & official ‘Excellence in Quality’ Project It is my pleasure to address you today on behalf of the Excellence in Quality and Management Forum and European Awards Night … Read More

Big Data Ethics

|

Ethical issues Big Data ethics involves adherence to the concepts of right and wrong behavior regarding data, especially personal data. Big Data ethics focuses on structured or unstructured data collectors and disseminators. Big Data ethics is supported, at EU level, … Read More

Epistemology of General Relativity

|

Early philosophical interpretations of the general theory of relativity are very diverse, each trying to identify Einstein as a follower of that philosophy. Mach’s supporters highlighted Einstein’s attempt to implement a “relativization of inertia” in general relativity (GR), and his … Read More

Causal theory of reference of Gareth Evans

|

Gareth Evans, in The Causal Theory of Names, states that the causal theory of reference needs to be expanded to include what he calls multiple “bases”. After the initial baptism, the use of the name in the presence of the … Read More

Tests and Anomalies of Post-Newtonian Gravitational Theories

|

Tests of post-Newtonian theories Newton’s proposed tests In the first edition of Principia, Newton considered that the experiments with the pendulum would allow him to decipher the different types of resistance force and their variation with speed. It recognizes the … Read More

Legal aspects of Big Data – GDPR

|

The use of Big Data presents significant legal problems, especially in terms of data protection. The existing legal framework of the European Union based in particular on the Directive no. 46/95/EC and the General Regulation on the Protection of Personal … Read More
