In the history of Newtonian Mechanics physicists and astronomers did not rely on so-called inertial frames, indeed they were not able to identify such frames. So the usual neo-Newtonian formalism of Newtonian Mechanics contains some superfluous components. In the present paper I will formulate a formal system for classical particle mechanics in Leibnizian space-time, where a relation, a counterpart of the second law of motion, between force on bodies and derivative of their momentum will be defined relative to every, inertial (...) or not, reference frame. And I will present a view that in the research process under Newtonian mechanics the accumulation of those models of the relation that satisfied some realistic conditions determined an additional structure of non-rotating frames to Leibnizian space-time.

The uncertainty relation in quantum mechanics has been explicated sometimes as a statistical relation and at other times as a relation concerning precision of simultaneous measurements. In the present paper, taking the indefiniteness of individual experiments as represented by diameters of Borel sets in projection-valued measure, we mathematically distinguish four expressions, two statistical and two concerning simultaneous measurements, of the uncertainty relation, study their interrelations, and prove that they are nonequivalent to each other and to the eigenvector condition (EV) in (...) infinite-dimensional Hilbert space.

日本の国家、国民精神、法学は、いかにあるべきか―。共和主義と立憲主義を理論的柱とし、国家共同体を支え、形成する国民の蒸神の在り方を探る「市民法学」の輪郭を提示。.

Pyridoxal 5′‐phosphate, the vitamin B6 derivative, acts as the coenzyme of many enzymes involved in amino acid metabolism. Exceptionally, this compound was found covalently bound to glycogen phosphorylase, the key enzyme in the regulation of glycogen metabolism. Although it is essential for the function of phosphorylase, its direct role has remained an enigma. We have recently found that the glucose moiety of pyridoxal (5′)diphospho (1)‐α‐D‐glucose, a conjugate of pyridoxal 5′‐phosphate and glucose 1‐phosphate through a pyrophosphate linkage, is transferred to the (...) nonreducing end of glycogen, forming a new α‐1,4‐glucosidic linkage. This finding emphasizes the importance of the direct phosphate‐phosphate interaction between the coenzyme and the substrate in the phosphorylase catalytic reaction. We have proposed a catalytic mechanism for phosphorylase in which the phosphate group of pyridoxal 5′‐phosphate acts as an electrophile to the phosphate group of glucose 1‐phosphate. This appears to represent the first instance of the direct involvement of a phosphate group in catalysis by enzymes. (shrink)

As its name implies, Vasubandhu’s _Vyākhyāyukti_ (VyY) explains the logic or methodology (_yukti_) of exegesis or sūtra interpretation (_vyākhyā_) and only survives in a Tibetan translation. In recent years, research on this treatise has been gradually accumulating. However, due to the difficulty of the Tibetan translation, some of the arguments therein have been misunderstood. In this article, after reviewing the general framework of Vasubandhu’s method of interpreting the sūtras, I will present a newly discovered parallel regarding his discussion of the (...) “purpose, _prayojana_” of the sūtras and reread it through a close philological examination of various sources in Sanskrit and Tibetan. Thus, this article will first elucidate the details of Vasubandhu’s explanation of the purpose of the Buddha’s preaching using synonyms and will clarify an aspect of his views on the Buddha’s word. In addition, concerning this “purpose,” I will elucidate the characteristics of the final chapter of this text, which provides stories about hearing the Buddha’s words with respect. By doing so, I would like to reveal the characteristics of the VyY as a manual for vivid preaching. (shrink)

時間が流れるとはどういうことか。時間は本当に流れているのか。西田幾多郎は合理的に理解可能な一つの「世界」を描いた。「永遠の今の自己限定」に帰着するその全貌を解読する。そしてそこから、西田哲学が封印した もう一つの時間論が浮上する。.

This paper offers some ideas and methods of consensus building towards integration of values in flood control, environment, and landscape. These three factors sometimes oppose to each other in the process of construction of public infrastructure such as roadbuilding and river improvement. It is crucial to avoid or resolute conflicts between the government and the local people through project management with the consensus building process. In public works in Japan, flood control has been given priority over the environmental preservation and (...) the landscape conservation due to the perception that it is through flood control that the life and property of individuals are adequately protected. As a consequence, the landscape and the environment have been paid only lip‐service. In the case of the Ohashi River Project in Izumo region presented in this paper, however, the river repair process might entail a severe blow to the tourism industry and have a dramatic impact on the fishery resources of the region, which would be considered a major loss in terms of the urban development of the city. One of our concerns is thus to avoid any losses, through proper consideration of the relationship between the three crucial factors. In this paper, the author reports some ideas and methods that appear in “Basic Policy for the Development of the Area around Ohashi River” composed by the Matsue Review Committee on the Development of the Area around the Ohashi River, in which the author is involved as a committee member. The most important task of the Committee wasto search for the ideas and methods to harmonize the values of flood control, environment, and landscape. (shrink)

西田幾多郎の哲学は、単なる宗教体験の表現ではない合理的世界観である。その全貌を解読する時、われわれは、西田哲学が封印したもう一つの視点を発見する。そこであらわになるのは、驚くべき「時間」の真相―時間幻 想である。.
