The notion of transdisciplinary science and technology has been gradually formed during
struggles to establish the recognition of non-natural scientific foundation of engineering. This article
presents the way the struggle has been conducted in the author’s step-by-step advance towards
the understanding of transdisciplinary science and technology. Similar notions related to transdisciplinary
science and technology, such as “pure engineering” and “design sciences”, are discussed in
the context of engineering education and social relevance of science and technology. The importance
of the transdisciplinary science and technology in the future techno-society is discussed. Consilience
of knowledge is discussed in the light of transdisciplinary science and technology.
The key issue of the role of the science and technology in the 21st century is how to
create the socio-economic value through the science & technology innovation process. The roll of
the transdisciplinary science and technology is indispensable to build up Japan in the 21st century
for both the national innovation system and also for the global sustainable innovation ecosystem.
Building the Innovation Pipe Network Systems is proposed connecting the kowledge creation and
the socio-economic value creation in conjunction with the roll of the transdisciplinary science and
Activities of collection and exchange of knowledge in the Society for Science on Form,
Japan, are described. The society was originated in the joint meetings of the groups of “physics of
form” and “stereology”. The word KATACHI (Japanese expression of “form”) has a less-restricted
definition and has meanings of gaining some completeness. That is contrasted with the western
word “symmetry” which has a clear definition and gives norms of beauty. KATACHI appears in all
fields and its notion can be shared beyond the difference in the terminology of different fields. It
is found that researches from broad range of fields in science, technology and art, can have active
discussions and exchange of knowledge under the aspect of KATACHI. It is expected that the aspects
of KATACHI in a variety of fields lead to a transdisciplinary integration of knowledge.
The modern statistical methodology and practical statistical sciences have been systematically
generated since the establishment of the grammar of science for recognition to give laws to
Nature in 1892 by K. Pearson. The author proposes to construct a new grammar of science for design
and corresponding new mathematical or statistical methodology to improve the laws for society
such as the Taguchi method. In this new grammar, not passive facts based on the researchers’ sense
impression but active facts designed by numerical simulation will take an essential role. The author
also introduces recent research activities in Japanese Society for Quality Control to establish new
statisical methodology for technology developments based on numerical simulation.
The ubiquitous services are paid to attention as social infrastructure services in which the
range of the applications reaches the entire society. The acceptability as a social system is required
in such social infrastructure services. In this paper, both an integrated knowledge structure and the
function creation process are clarified by classifying the Koto-Tukuri in the ubiquitous services using
Duality plays a pivotal role in every field of science and engineering, but its concrete
meaning is diverse. In search of duality-based technology duality concepts are classified and the role
of duality in optimization and control is discussed. As fundamental duality phenomena in mathematics,
emphasis is laid on the dual space in linear algebra and the Legendre transformation for convex
functions. Duality between connotation and denotation is also explained. Two specific examples
indicate recent fruitful interactions between different areas through duality.
This paper considers the view of artifact in the Japanese culture, through the comparison
with aWestern Europe modern culture. Concretely, though the clock technology had been introduced
into Japan in the Muromachi age, why it had not developed to the automatic technology as inWestern
Europe is discussed.
