1156The intelligence cycle is a set of processes used to provide useful information for decision-making. The cycle consists of several processes. The related counter-intelligence area is tasked with preventing information efforts from others. A basic model of the process of collecting and analyzing information is called the "intelligence cycle". This model can be applied, and, like all the basic models, it does not reflect the fullness of real-world operations. Through intelligence cycle activities,…Read more

687După încheierea Războiului Rece, guvernele și agențiile de informații au continuat să utilizeze modelul convențional pentru a evalua amenințările de stat. Dar conceptele de securitate s-au îndepărtat de o confruntare extrem de militarizată între adversari cunoscuți și a crescut îngrijorarea față de amenințările nestatale mai greu de identificat. Actorii nestatali au devenit amenințări strategice, conceptul de "terorism strategic" fiind dezvoltat imediat după atacurile din septembrie 2001. Au exi…Read more

727A presentation of Hooke’s 1674 monograph introducing the idea of universal gravity was included in the Philosophical Transactions (Royal Society 1775) and subsequently several letters containing observations, including one of Huygens. But obviously, after the publication of Principia in 1687, Hooke’s priority in proposing universal gravitation was forgotten. Hooke, considered as a “mechanical genius” rather than a scientist, was often at a social disadvantage to Newton, the noble theorist, or Hu…Read more

960Popper's supporters argued that most criticism is based on an incomprehensible interpretation of his ideas. They argue that Popper should not be interpreted as meaning that falsifiability is a sufficient condition for the demarcation of science. Some passages seem to suggest that he considers it is only a necessary condition. Other passages would suggest that for a theory to be scientific, Popper requires (besides falsifiability) other tests, and that negative test results are accepted. A demarc…Read more

719Dans une note intitulée « Un état vrai de l'affaire et la controverse entre Sr Isaak Newton et le Dr Robert Hooke comme priorité de cette noble hypothèse du mouvement des planètes autour du Soleil en tant que leurs centres » non publié au cours de sa vie, Hooke a décrit sa théorie de la gravité. Pour soutenir sa « priorité », Hooke cite ses conférences sur les mouvements planétaires du 23 mai 1666, « Une tentative de prouver le mouvement de la Terre à partir d'observations » publiées en 1674 et …Read more

1798The methodology of scientific research programmes is a collection of papers published over time expressing a radical review of Popper's demarcation criterion between science and non-science, leading to a new theory of scientific rationality. Volume I address aspects of the philosophy of science, and volume II contains works on the philosophy of mathematics. For a science historian, the reconstruction proposed by Lakatos is attractive and explains the evolution of science to a level that has not …Read more

10174Thomas Kuhn criticized falsifiability because it characterized "the entire scientific enterprise in terms that apply only to its occasional revolutionary parts," and it cannot be generalized. In Kuhn's view, a delimitation criterion must refer to the functioning of normal science. Kuhn objects to Popper's entire theory and excludes any possibility of rational reconstruction of the development of science. Imre Lakatos said that if a theory is scientific or non-scientific, it can be determined ind…Read more

495Falsificaționismul dogmatic admite falsificabilitatea tuturor teoriilor științifice fără calificare, dar păstrează un fel de bază empirică infailibilă. Este strict empiricist fără a fi inductivist: neagă faptul că certitudinea bazei empirice poate fi transmisă teoriilor. Astfel, falsificabilitatea dogmatică este cea mai slabă marcă a justificării. Semnul distinctiv al falsificării dogmatice este recunoașterea faptului că toate teoriile sunt la fel de conjecturale. Știința nu poate dovedi nicio t…Read more

733Intelligence services are currently focusing on the fight against terrorism, leaving relatively little resources to monitor other security threats. For this reason, they often ignore external information activities that do not pose immediate threats to their government's interests. Extremely few external services operate globally. Almost all other services focus on immediate neighbors or regions. These services usually depend on relationships with these global services for information on areas b…Read more

1421A scientific theory, according to Popper, can be legitimately saved from falsification by introducing an auxiliary hypothesis to generate new, falsifiable predictions. Also, if there are suspicions of bias or error, the researchers might introduce an auxiliary falsifiable hypothesis that would allow testing. But this technique can not solve the problem in general, because any auxiliary hypothesis can be challenged in the same way, ad infinitum. To solve this regression, Popper introduces the ide…Read more

723Tarkovsky a dezvoltat o teorie a cinematografiei pe care a numit-o "sculptarea în timp". Prin aceasta el a vrut să evidențieze caracteristica unică a cinematografiei ca mediu, aceea de aborda experiența noastră despre timp și de a o modifica. Filmul neregulat transcrie timpul în timp real. Folosind filmări lungi și câteva tăieturi în filmele sale, el a urmărit să ofere spectatorilor un sentiment de trecere a timpului, timpul pierdut și relația dintre un moment de timp și altul. El consideră cine…Read more

732Blockchain, denumit inițial lanț de blocuri, este o listă în continuă creștere de înregistrări numite blocuri, care comunică între ele prin mesaje criptografiate. Fiecare bloc conține un hash criptografic al blocului anterior, un marcaj de timp și datele tranzacției. Prin proiectare, un blockchain este "un registru deschis, distribuit, care poate înregistra tranzacțiile între două părți eficient și într-un mod verificabil și permanent", de obicei gestionat de o rețea peer-to-peer care aderă la u…Read more

687According 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".…Read more

2067In 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 principl…Read more

531Interpretarea textelor lui Isaac Newton a suscitat numeroase controverse, până în zilele noastre. Una din cele mai aprinse dezbateri este legată de acțiunea între două corpuri aflate la distanță unul de celălalt (atracția gravitațională), și în ce măsură Newton a implicat pe Dumnezeu în acest caz. Practic, majoritatea lucrărilor discută patru tipuri de atracții gravitaționale în cazul corpurilor aflate la distanță: acțiunea la distanță directă ca proprietate intrinsecă a corpurilor în sens epicu…Read more

1174Despite 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 test…Read more

963As John Henry states, Newton simply wants to reaffirm the truth of God's omnipresence without directly involving him in the physics of the world system. Newton simply wants to distance himself from a Cartesian concept of God and convince the atheists that God is a real presence extended in the world. God must exist in space for the space to exist, but God does not only act through contact. Henry believes that Andrew Janiak and Hylarie Kochiras give us a wrong picture of a Newton who believes in …Read more

1280Călătoria în timp implică deplasarea într-un timp diferit de cel prezent, în trecut sau în viitor, în principiu fără o deplasare în spațiu cu referire la un sistem de coordonate local. Călătoria în timp poate fi făcută de un corp material care poate fi sau nu o ființă vie, și pentru care se folosește de obicei un dispozitiv special denumit mașina timpului. Călătoria în timp este un concept recunoscut în filosofie și știință, dar a cărui posibilitatea este foarte disputată, dând naștere la numero…Read more

667The perception of intelligence as power has intensified during the Second World War, when several intelligence agencies has been formalized and significantly increased. In all countries, new agencies and departments have been set up to deal with threats. Government publications in developed countries, following the September 11, 2001 attack, reflected a consensus that intelligence services are key to preventing mass attacks, spending huge amounts for the intelligence agencies that are considered…Read more

3526Isaac Newton on the action at a distance in gravity: With or without God?MultiMedia Publishing. 2019.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 …Read more

606Dans la définition de l'eugénisme, il est très difficile d'établir une distinction claire entre la science (médecine, génie génétique) et l'eugénisme. Et de définir une ligne de conduite sur laquelle l'ingénierie génétique ne devrait pas aller, conformément aux normes morales, juridiques et religieuses. Tant que nous acceptons l'aide de la génétique pour trouver des moyens de lutter contre le cancer, le diabète ou le VIH, nous acceptons également l'eugénisme positif tel qu'il est actuellement.

1637There is, among some scientists and philosophers, the idea that any theory that would allow the time travel would introduce causal issues. These types of temporal paradoxes can be avoided by the Novikov self-consistency principle or by a variation in the interpretation of many worlds with interacting worlds. The world in which we live has, according to David Lewis, a Parmenidean ontology: "a manifold of events in four dimensions," and the occupants of the world are the 4-dimensional aggregates o…Read more

643Gravitația clasică newtoniană admite o descriere geometrică. Împreună cu relativitatea specială, aceasta permite o descriere euristică a teoriei relativității generale. Mișcarea inerțială din mecanica clasică este legată de geometria spațiului și timpului, practic de-a lungul unor geodezice în care liniile de univers sunt linii drepte în spațiu-timpul relativist. Conform relativității generale, forţa de gravitaţie este o manifestare a geometriei locale spaţiu-timp. Relativitatea generală este o …Read more

2564Karl Popper, en tant que rationaliste critique, a été un opposant à toutes les formes de scepticisme, de conventionnalisme et de relativisme scientifique. En 1935, il a écrit Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft, traduisant plus tard le livre en anglais et le publiant sous le titre The Logic of Scientific Discovery (1959), considéré comme un travail de pionnier dans son domaine. De nombreux arguments de ce livre sont dirigés contre les membres du « Cercle de …Read more

1177General 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 b…Read more

86Climate Change - Global WarmingMultiMedia Publishing. 2018.A brutal and catastrophic warming could put humanity in short-term risk, a climate hypothesis that was first presented as highly speculative and subject to more science fiction than a serious prospective, before taking consistency by the scientists from the Rio Summit, and the difficulties of implementing the Kyoto Protocol. This possibility is beginning to be considered by the futurists, including the Intergovernmental Panel on Climate Change (IPCC), under the aegis of the UN, then a university…Read more
