Dear Nicolae Sfetcu, Re: Summit of Leaders 2019 (Oxford UK) & official ‘Best Enterprises/Manager of the Year’ Project On December 17, the traditional Summit of Leaders and the Socrates Awards Ceremony will be held at the Oxford Town Hall. The … Read More

Strong Field Gravitational Tests

|

When the density of the body becomes large enough, general relativity predicts the formation of a black hole. The neutron stars of about 1.4 solar masses and the black holes are the final stage for the evolution of the massive … Read More

Modern Tests of Relativistic Gravitational Theories

|

Dicke and Schiff established a framework for testing general relativity, [1] including through null experiments and using the physics of space exploration, electronics and condensed matter, such as the Pound-Rebka experiment and laser interferometry. The gravitational lens tests and the … Read More

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
