Ontology engineering, along with semantic Web technologies, allow the semantic development and modeling of the operational flow required for blockchain design. The semantic Web, in accordance with W3C, “provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries” and can be seen as an integrator for various content, applications and information systems. The most widely used blockchain modelling system, by abstract representation, description and definition of structure, processes, information and resources, is the enterprises modelling. Enterprise modelling uses domain ontologies by model representation languages.

The distinction between falsification and refutation in the demarcation problem of Karl Popper
Despite the criticism of Karl Popper’s falsifiability theory for the demarcation between science and non-science, mainly pseudo-science, this criterion is still very useful, and perfectly valid after it was perfected by Popper and his followers. Moreover, even in his original version, considered by Lakatos as “dogmatic”, Popper did not assert that this methodology is an absolute demarcation criterion: a single counter-example is not enough to falsify a theory; a theory can legitimately be saved from falsification by introducing an auxiliary hypothesis. Compared to Kuhn’s theory of revolutions, which he himself later dissociated from it transforming it into a theory of “micro-revolutions,” I consider that Popper’s demarcation methodology, along with the subsequent development proposed by him, including the corroboration and the verisimilitude, though imperfect, is not only valid today, but it is still the best demarcation methodology. For argumentation, I used the main works of Popper dealing with this issue, and his main critics and supporters. After a brief presentation of Karl Popper, and an introduction to the demarcation problem and the falsification methodology, I review the main criticisms and the arguments of his supporters, emphasizing the idea that Popper has never put the sign of equality between falsification and rejection. Finally, I present my own conclusions on this issue.

The distinction between falsification and refutation in the demarcation problem of Karl Popper
Lakatos on justificationism
According to the scientific “justificationist” method, knowledge consisted of proven sentences. Classical intellectuals (or “rationalists,” in the narrow sense of the term) have accepted extremely varied – and powerful “proofs“, through revelation, intellectual intuition, experience. These, with the help of logic, have allowed them to prove any kind of scientific statement. Classical empiricists accepted as axioms only a relatively small set of “factual propositions” that expressed “hard facts”. The value of their truth has been established by experience and has been the empirical basis of science.

About God in Newton’s correspondence with Richard Bentley and Queries in Opticks
In Newton’s correspondence with Richard Bentley, Newton rejected the possibility of remote action, even though he accepted it in the Principia. Practically, Newton’s natural philosophy is indissolubly linked to his conception of God. The knowledge of God seems to be essentially immutable, unlike the laws of nature that can be subjected to refining, revision and rejection procedures. As Newton later states in Opticks, the cause of gravity is an active principle in matter, but this active principle is not an essential aspect of matter, but something that must have been added to matter by God, arguing in the same Query of Opticks even the need for divine intervention.

Isaac Newton on the action at a distance in gravity: With or without God?
The interpretation of Isaac Newton’s texts has sparked controversy to this day. One of the most heated debates relates to the action between two bodies distant from each other (the gravitational attraction), and to what extent Newton involved God in this case. Practically, most of the papers discuss four types of gravitational attractions in the case of remote bodies: direct distance action as intrinsic property of bodies in epicurean sense; direct remote action divinely mediated by God; remote action mediated by a material ether; or remote action mediated by an immaterial ether. The purpose of this paper is to argue that Newton categorically rejected the types of direct action as the intrinsic property of bodies, and remote action mediated by a material ether. Concerning the other two types of action, direct through divine intervention and mediated through an immaterial environment, Newton has repeatedly stated that he does not know the exact cause of gravity, but in both cases, he has directly involved God, directly in the first case and as the primary cause (the environment/ether being the secondary cause) in immaterial mediated action. But since recognition of direct distance action could have given some credit to those who thought gravity could be essential to matter, and hence to atheism, Newton never openly acknowledged the possibility of such an idea.

Causal Loops in Time Travel
About the possibility of time traveling based on several specialized works, including those of Nicholas J. J. Smith (“Time Travel“), William Grey (”Troubles with Time Travel”), Ulrich Meyer (”Explaining causal loops”), Simon Keller and Michael Nelson (”Presentists should believe in time-travel”), Frank Arntzenius and Tim Maudlin (“Time Travel and Modern Physics“), and David Lewis (“The Paradoxes of Time Travel”). The article begins with an Introduction in which I make a short presentation of the time travel, and continues with a History of the concept of time travel, main physical aspects of time travel, including backward time travel in the past in general relativity and quantum physics, and time travel in the future, then a presentation of the Grandfather paradox that is approached in almost all specialized works, followed by a section dedicated to the Philosophy of time travel, and a section in which I analyze Causal loops for time travel. I finish my work with Conclusions, in which I sustain my personal opinions on the time travel, and the Bibliography on which the work is based.

The new (liberal) eugenics
Despite the Nazi horrors, in 1953 the new eugenics was founded, when Watson and Crick postulated the double helix of DNA as the basis of chemical heredity. In 1961, scientists have deciphered the genetic code of DNA, laying the groundwork for code manipulation and the potential building of new life forms. After thirty years from the discovery of the DNA structure, the experimenters began to carry out the first clinical studies of human somatic cell therapy.
The practice of prenatal genetic tests identifies genes or unwanted genetic markers. Parents can choose to continue pregnancy or give up the fetus. Once the preimplantation genetic diagnosis occurs, potential parents can choose to use in vitro fertilization and then test early embryonic cells to identify embryos with genes they prefer or avoid. Because of concerns about eugenics, genetic counseling is based on a “non-directive” policy to ensure respect for reproductive autonomy. The argument for this counseling service is that we should balance parental autonomy with child’s autonomy in the future. Specialists have not yet given a clear answer to the question of whether these practices should be considered eugenic practices, or if they are moral practices.

The Ontology of General Relativity
General Relativity generated various early philosophical interpretations. His adherents have highlighted the “relativization of inertia” and the concept of simultaneity, Kantians and Neo-Kantians have underlined the approach of certain synthetic “intellectual forms” (especially the principle of general covariance, and logical empirics have emphasized the philosophical methodological significance of the theory.
Reichenbach approached the GR through the “relativity of geometry” thesis, trying to build a “constructive axiomatization” of relativity based on “elementary matters of fact” (Elementartatbestande) for the observable behavior of light rays, rods and clocks.
The mathematician Hermann Weyl attempted a reconstruction of Einstein’s theory based on the epistemology of a “pure infinitesimal geometry”, an extended geometry with additional terms that formally identified with the potential of the electromagnetic field.

Space, time, and time travel
Newton supported the idea of absolute time, unlike Leibniz, for which time is only a relation between events and cannot be expressed independently, a statement in concordance with the relativity of space-time.
Eternalism claims that the past and the future exist in a real sense, going to the idea that time is a dimension similar to spatial dimensions, that future and past events are “present” on the axis of time, but this view is challenged. On four-dimensional vision, the universe is an existing space-time topology, containing everything that has happened, everything that happens and everything that’s going to happen. It follows that there is no singular moment to be considered as insignificant as present. Time travel is possible if the four-dimensional vision including the time is correct, but it is not possible if presentism is true. William Godfrey-Smith says that “the metaphysical image underlying the discussion of time travel is that of the universe block, in which the world is conceived as extended in time as it is in space.”

Science and pseudoscience – Falsifiability
The delimitation between science and pseudoscience is part of the more general task of determining which beliefs are epistemologically justified. Standards for demarcation may vary by domain, but several basic principles are universally accepted.
Karl Popper proposed falsifiability as an important criterion in distinguishing between science and pseudoscience. He argues that verification and confirmation can play no role in formulating a satisfactory criterion of demarcation. Instead, it proposes that scientific theories be distinguished from non-scientific theories by testable claims that future observations might reveal to be false.
