It follows from the proved theorems that ifM π=〈Q, ϕ〉 (whereQ={0,q 1,q 2,...,q α}) is a machine of the classM F then there exist α machinesM πi such thatM πi(〈1,c〉)=M π(〈q i,c〉) andQ i={0, 1, 2, ..., α+1} (i=1, 2, ..., α).And thus, if the way in which to an initial function of content of memoryc∈C a machine assigns a final onec′∈C is regarded as the only essential property of the machine then we can deal with the machines of the (...) formM π=〈{0, 1, 2, ..., α}, ϕ〉 and processes π(t) (wheret=〈1,c〉,c∈C) only.Such approach can simplify the problem of defining particular machines of the classM F , composing and simplifying them.

The old-fashioned concept of state is shown to be inadequate and misleading. Replacing it by a concept of information and taking advantage of the invariance of the mechanical description under time reversal puts the problems of the interpretation of quantum mechanics in a new light. A more realistic interpretation appears to be possible. Moreover, a new explanation of the Einstein-Podolsky-Rosen paradox is presented, too.

In this paper we introduce a new technique of proving undecidability results. This technique is based on the notion of a Thue tree. We also give examples of applications of this method to term rewriting, Horn implication problem and database dependencies.

There are few opinions as soundly rooted and commonly acknowledged as the notion of usefulness of education. There is a deep belief, proved right by the experience of mankind, that an educated person has the advantage over a simpleton. It is considered that educated individuals understand themselves and the world around them better. Therefore, they are more a homo rationalis than uneducated ones.In the world changing as in a kaleidoscope an educated person must have the skill to absorb incoming information (...) easily and quickly, to select it and then process into substantial knowledge about the world. At the same time, they need to be reliable and highly efficient in its particular applications. In a word, an educated person needs to know how to develop their individual capital of knowledge. The average age of starting a career increases. Keeping up with fast occurring civilisation changes requires some outside assistance, and so the tasks for higher education are expanding to include theneed to organise lifelong learning.I think that the more effectively will an educational system deliver the abovementioned objectives-acquiring knowledge as such, understood as acquiring the truthabout the world and as increasing the intellectual potential of the society-the ’better’ it will be. This leads to perceiving also the system’s effectiveness as a value in itself, and achieving this value becomes the system’s priority.However, are the values and goals of the higher education mentioned above exclusive? What tradition is backing the priorities of universities nowadays? What should be changed to make the education in universities more efficient in the changing world?I am asking those difficult questions while not quite convinced that my opinion is the best and the only one possible, but I would like to make a small contribution to the discussion on values of education.

W latach 1931-1934 Kazimierz Ajdukiewicz sformułował dwie wersje teorii znaczenia. Tarski wykazał, że druga wersja teorii dopuszcza moż- liwość istnienia równoznacznych nazw o różnej denotacji. Cecha ta zo- stała uznana przez Tarskiego i Ajdukiewicza za dyskwalifikującą teorię. W artykule dokonuję porównania obu wersji teorii, przede wszystkim ze względu na podstawową definicję wzajemnej wymienialności wyrażeń. Pokazuję, że wbrew rozpowszechnionej opinii zarzut Tarskiego dotyczy także pierwszej wersji teorii. Siła argumentu Tarskiego opiera się na założeniu, że żadna adekwatna teoria znaczenia nie może dopuszczać (...) istnienia równoznacznych nazw o różnej denotacji. Podejmuję dyskusję z tym stanowiskiem. (shrink)

Author: Sawicki Jerzy Title: THELEOGICAL PRINCIPLE IN KANT’S METHODOLOGY (Zasada teleologiczna w metodologii Kanta) Source: Filo-Sofija year: 2005, vol:.5, number: 2005/1, pages: 281-292 Keywords: KANT, THELEOGICAL PRINCIPLE, FINALISM, MECHANICISM Discipline: PHILOSOPHY Language: POLISH Document type: ARTICLE Publication order reference (Primary author’s office address): E-mail: www:The work contains a concise of I. Kant’s views on the problem of the laws of nature and the theleological principle presented in this context, which Kant proposes in the character of a regulative methodological postulate. (...) The analysis of fundamental philosophical notions (the law of nature, necessity, causality, purpose) carried out from the position of an extreme aprioristic rationalism leads Kant to the conclusion about the basic impossibility of educing the conception of purpose (in relation to nature) from aprioristic transcendental laws, ie. such laws which the theoretical reason imposes to the nature by necessity. However, the fact of a total functioning of an organism does not fit, according to Kant, into the frames of a mechanically understood causality. Kant tries to solve this problem choosing the way of conclusion by analogy and finally he suggests to introduce into the living nature a specific causal relation in which the purposes constitute a particular kind of causes and results at the same time. That conception oscillates between mechanicism and theological finalism, and the fitting of a science system into the frames of aprioristic categories does not permit a finally decide about the supremacy of one or the other way of seeing the world. However, nevertheless, the perceiving and stressing of the peculiarity of organic symptoms, the formulation of the postulate about their unreductability to the law of a mechanical type constitute unquestionable and great merit of the author of the Criticism of the Judgment Authority. The idea of the totality of organism, though involved in subjective idealistic non consequences of Kant’s conceptions has in the given historical period all features of a deep and progressive thought, outpacing and inspiring several later research ideas, both in philosophy and in natural science.

Las jako zespół przyrody o określonych właściwościach pełni szereg wielorakich funkcji gospodar­czych, pośrednio gospodarczych i pozagospodar­czych. Jako przyrodnicza całość jest mało stabilny i ulega wielu czynnikom biotycznym, abiotycznym i antropogenicznym. Z praktyki ochrony lasu w granicach admini­stracyjnych Regionalnej Dyrekcji Lasów Państwo­wych w Olsztynie wynika, że szczególnie niebez­pieczne bywają owady - z grupy szkodników pier­wotnych - żerujące na drzewach żywych i pozornie zdrowych, a osłabionych działaniem jednego lub kil­ku czynników, zwykle abiotycznych. Pojawy nie­których zmuszają do podejmowania zabiegów ratow­niczych. Sposoby sprowadzania liczebności (...) trzech moty­li, tzn. brudnicy mniszki, strzygoni choinówki i zwójki zieloneczki, do poziomu przed laty nazywanego „żelaznym zapasem” przedstawia niniejsze opracowanie.
