On the Linearity of the Lorentz transformations. U. Hoyer's argument for the linearity is discussed and a modification of the argument is proposed.

U. Hoyer's argument for the linearity is discussed and a modification of the argument is proposed.

Within the framework of the Kershaw approach and of a hypothesis on spatial stochasticity, the relativistic equations of Lehr and Park, Guerra and Ruggiero, and Vigier for stochastic Nelson mechanics are obtained. In our model there is another set of equations of the hydrodynamical type for the drift velocityv i(x j,t) and stochastic velocityu i(x j,t) of a particle. Taking into account quadratic terms in l, the universal length, we obtain from these equations the Sivashinsky equations forv i(x j,t) in (...) the caseu i →0. In the limit l →0, these equations acquire the Newtonian form. (shrink)

For a sufficiently large class of formal systems a duality theorem is proved. We consider such formal set theories $\widetilde{\scr{T}}$ [2] which, at least, satisfy the following conditions: 1. The theory $\widetilde{\scr{T}}$ contains its own (either bounded or introduced by a definition) substantive constant U, for which $\vdash \forall x[x\in U]$ or $\vdash \forall x[x\subset U]$ . 2. The operation of "complement", denoted by C, is defined with respect to U. 3. For any formula (resp. a term), A ⊦ A (...) ↔ ⅂⅂ A (resp. ⊦ CCA = A), and some basic conclusions follow. (shrink)

There is no unique way to generalize the mass operator 0 2 −p · p to curved spacetimes. The possible generalizations using either an analytic or an algebraic (group-theoretic) approach are discussed. We investigate in detail three possibilities: (i) the generalized D'Alembertian $$- \tilde \square = - (1/\sqrt { - g} )(\partial /\partial x^v )(\sqrt { - g} g^{\mu v} {\text{ }}\partial /\partial x^\mu$$ (ii) the operator ( $- (\tilde \square + \tfrac{1}{6}{\text{R)}}$ , which is conformally invariant in the massless (...) case, and (iii) an operator suggested by Meggs for Robertson-Walker spacetimes. A criterion for choosing among the different possibilities is proposed. It is used to eliminate the Meggs operator, but is not stringent enough to decide between the other two. (shrink)

في كتابه من نقد العقل إلى هيرمينوطيقا الرموز: بحث في فلسفة الثقافة عند إرنست كاسيرر، الصادر عن المركز العربي للأبحاث ودراسة السياسات، يحاول فؤاد مخوخ التركيز على فلسفة كاسيرر، ساعيًا لإثبات أصالتها وجِدَّتِها في مجال نقد الثقافة. فـ "قراءة كاسيرر فلسفة كانط"، كما يقول مخوخ، "متميزة وأصيلة، ويتجلى ذلك في مشروع تطوير نقد العقل وتمديده إلى نقد الثقافة الذي تجسد في فلسفة الأشكال الرمزية باعتبارها فلسفةً للثقافة، وتقعيدًا نظريًا لإبيستمولوجيا علوم الثقافة، وهيرمينوطيقا لتأويل عالَم الإنسان وفهمه".

In the article the issue of singling out some systemic criteria of differentiation between the fundamental and applied terminologies is considered. The authors point at the fact that each terminology has its own individual peculiarities, which mark it out against a general background of the terminological fund of a certain language. It is asserted that one of the most important and effective criteria that can be the basis of the approach to the study of sublanguages for special purposes is a (...) fundamental or applied character of the sphere of professional or scientific knowledge verbalized by a certain terminology. Such terms, as ‘fundamental terminology‘, ‘applied terminology‘ and ‘terminology of transition type‘, are introduced for scientific use. The fundamental terminology is understood as a sublanguage for special purposes that verbalizes the notions, forming the totality of fundamental knowledge, serving for the description of phenomena and processes in reality and in science, in the framework of which the fundamental research is carried out. The applied terminology is the name for the sublanguage for special purposes representing the notions, in which the results of human being’s practical scientific-industrial activity for changing the reality, forming the artificial habitat, are conceptualized. The terminology of transition type is the terminology that verbalizes the fragments of the field of scientific knowledge in which the research can have both a fundamental and applied character. The authors come to the conclusion that pure applied or fundamental terminologies are quite rare, that it is rational to speak about the degree of manifestation of the applied or fundamental character within the limits of this or that terminological system.

The topic of our discussion is extremely complex by virtue of the diversity of problems it covers, their contradictions, and their many layers. An objective analysis is complicated by the fact that we are "by origin from there," that we were all drawn into the process, and that it is difficult, if not impossible, for us to distance ourselves from this fact. Being involved in what happened is, on the one hand, a positive factor: it gives access to occurring events (...) through a knowledge of facts and details that is difficult, if not impossible, to obtain for an investigator of the events many years later. But such involvement not only discloses the truth, it also creates the illusion that one possesses the truth, because a participant in events often makes his personal beliefs about them the basis of theoretical generalizations. A participant and a witness are very different categories in terms of their objective relation to actual facts. (shrink)
